Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Basis of Presentation In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary for a fair presentation of results for such periods. Albany International Corp. (Albany, the Registrant, the Company, we, us, or our) consolidates the financial results of its subsidiaries for all periods presented. The results for any interim period are not necessarily indicative of results for the full year. The preparation of financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in Albany International Corp.’s Consolidated Financial Statements and accompanying Notes. Actual results could differ materially from those estimates. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with Albany International Corp.’s Annual Report on Form 10-K for the year ended December 31, 2020.

Segment Reporting [Abstract]
Reportable Segments and Revenue Recognition	Reportable Segments and Revenue Recognition In accordance with applicable disclosure guidance for enterprise segments and related information, the internal organization that is used by management for making operating decisions and assessing performance is used as the basis for our reportable segments. The Machine Clothing (“MC”) segment supplies permeable and impermeable belts used in the manufacture of paper, paperboard, tissue and towel, nonwovens, fiber cement and several other industrial applications. We sell our MC products directly to customer end-users in countries across the globe. Our products, manufacturing processes, and distribution channels for MC are substantially the same in each region of the world in which we operate. We design, manufacture, and market paper machine clothing (used in the manufacturing of paper, paperboard, tissue and towel) for each section of the paper machine and for every grade of paper. Paper machine clothing products are customized, consumable products of technologically sophisticated design that utilize polymeric materials in a complex structure. The Albany Engineered Composites (“AEC”) segment, including Albany Safran Composites, LLC (“ASC”), in which our customer SAFRAN Group (“Safran”) owns a 10 percent noncontrolling interest, provides highly engineered, advanced composite structures to customers in the commercial and defense aerospace industries. AEC’s largest program relates to CFM International’s LEAP engine. Under this program, AEC through ASC, is the exclusive supplier of advanced composite fan blades and cases under a long-term supply contract. AEC net sales to Safran were $54.0 million and $57.0 million in the first six months of 2021 and 2020, respectively. The total of Accounts receivable, Contract assets and Noncurrent receivables due from Safran amounted to $105.1 million and $127.1 million as of June 30, 2021 and December 31, 2020, respectively. Other significant programs by AEC include the F-35, Boeing 787, Sikorsky CH-53K and JASSM, as well as the fan case for the GE9X engine. In 2020, approximately 46 percent of AEC sales were related to U.S. government contracts or programs. The following tables show data by reportable segment, reconciled to consolidated totals included in the financial statements: Three months ended June 30, Six months ended June 30, (in thousands) 2021 2020 2021 2020 Net sales Machine Clothing $ 159,921 $ 153,433 $ 308,127 $ 290,035 Albany Engineered Composites 74,598 72,557 148,753 171,719 Consolidated total $ 234,519 $ 225,990 $ 456,880 $ 461,754 Operating income/(loss) Machine Clothing $ 55,902 $ 56,543 $ 106,264 $ 103,718 Albany Engineered Composites 7,164 8,299 10,102 15,922 Corporate expenses (13,100) (12,115) (24,581) (27,319) Operating income $ 49,966 $ 52,727 $ 91,785 $ 92,321 Reconciling items: Interest income (401) (348) (930) (795) Interest expense 4,619 4,171 8,717 8,595 Other expense/(income), net 862 1,091 1,462 16,660 Income before income taxes $ 44,886 $ 47,813 $ 82,536 $ 67,861 There were no material changes to total assets of the reportable segments in the first six months of 2021. The table below presents restructuring costs by reportable segment (also see Note 4): Three months ended June 30, Six months ended June 30, (in thousands) 2021 2020 2021 2020 Machine Clothing $ 10 $ 388 $ (58) $ 1,030 Albany Engineered Composites (48) 2,248 41 2,248 Corporate expenses 29 201 60 201 Total $ (9) $ 2,837 $ 43 $ 3,479 Products and services provided under long-term contracts represent a significant portion of sales in the Albany Engineered Composites segment and we account for these contracts using the percentage of completion (actual cost to estimated cost) method. That method requires significant judgment and estimation, which could be considerably different if the underlying circumstances were to change. When adjustments in estimated contract revenues or costs are required, any changes from prior estimates are included in earnings in the period the change occurs. Changes in the estimated profitability of long-term contracts could be caused by increases or decreases in the contract value, revisions to customer delivery requirements, updated labor or overhead rates, factors affecting the supply chain, changes in the evaluation of contract risks and opportunities, or other factors. Changes in the estimated profitability of long-term contracts increased operating income by $4.3 million and $3.7 million for the second quarter and first half of 2021, respectively. Adjustments in the estimated profitability of long-term contracts increased operating income by $7.4 million and $6.4 million for the second quarter and first half of 2020, respectively. We disaggregate revenue earned from contracts with customers for each of our business segments and product groups based on the timing of revenue recognition, and groupings used for internal review purposes. The following table disaggregates revenue for each product group by timing of revenue recognition: Three months ended June 30, 2021 (in thousands) Point in Time Revenue Recognition Over Time Revenue Recognition Total Machine Clothing $ 159,056 $ 865 $ 159,921 Albany Engineered Composites ASC — 26,170 26,170 Other AEC 4,432 43,996 48,428 Total Albany Engineered Composites 4,432 70,166 74,598 Total revenue $ 163,488 $ 71,031 $ 234,519 Six months ended June 30, 2021 (in thousands) Point in Time Revenue Over Time Revenue Total Machine Clothing $ 306,397 $ 1,730 $ 308,127 Albany Engineered Composites ASC — 53,254 53,254 Other AEC 8,312 87,187 95,499 Total Albany Engineered Composites 8,312 140,441 148,753 Total revenue $ 314,709 $ 142,171 $ 456,880 Three months ended June 30, 2020 (in thousands) Point in Time Revenue Recognition Over Time Revenue Recognition Total Machine Clothing $ 152,585 $ 848 $ 153,433 Albany Engineered Composites ASC — 17,576 17,576 Other AEC 4,143 50,838 54,981 Total Albany Engineered Composites 4,143 68,414 72,557 Total revenue $ 156,728 $ 69,262 $ 225,990 Six months ended June 30, 2020 (in thousands) Point in Time Revenue Over Time Revenue Total Machine Clothing $ 288,339 $ 1,696 $ 290,035 Albany Engineered Composites ASC — 55,470 55,470 Other AEC 10,463 105,786 116,249 Total Albany Engineered Composites 10,463 161,256 171,719 Total revenue $ 298,802 $ 162,952 $ 461,754 The following table disaggregates MC segment revenue by significant product groupings (paper machine clothing (PMC) and engineered fabrics), and, for PMC, the geographical region to which the paper machine clothing was sold: Three months ended June 30, Six months ended June 30, (in thousands) 2021 2020 2021 2020 Americas PMC $ 82,343 $ 81,225 $ 155,645 $ 154,902 Eurasia PMC 55,900 54,166 111,043 99,297 Engineered Fabrics 21,678 18,042 41,439 35,836 Total Machine Clothing Net sales $ 159,921 $ 153,433 $ 308,127 $ 290,035 As permitted by ASC 606, we only disclose the value of unsatisfied performance obligations for contracts with an original expected duration of greater than one year. Contracts in the MC segment are generally for periods of less than a year. Most contracts in the AEC segment are short duration firm-fixed-price orders representing performance obligations with an original maturity of less than one year. Remaining performance obligations on contracts that had an original duration of greater than one year totaled $149 million and $85 million as of June 30, 2021 and 2020, respectively, and related primarily to firm contracts in the AEC segment. Of the remaining performance obligations as of June 30, 2021, we expect to recognize as revenue approximately $48 million during 2021, $62 million during 2022, $24 million during 2023, and the remainder during 2024.

Retirement Benefits [Abstract]
Pensions and Other Postretirement Benefit Plans	Pensions and Other Postretirement Benefit Plans The Company has defined benefit pension plans covering certain U.S. and non-U.S. employees. The Company also provides certain postretirement benefits to retired employees in the U.S. and Canada. The Company accrues the cost of providing these benefits during the active service period of the employees. The composition of the net periodic benefit cost for the six months ended June 30, 2021 and 2020, was as follows: Pension plans Other postretirement benefits (in thousands) 2021 2020 2021 2020 Components of net periodic benefit cost: Service cost $ 1,090 $ 1,148 $ 66 $ 100 Interest cost 2,674 3,071 551 857 Expected return on assets (3,211) (3,415) — — Settlement — 145 — — Curtailment — 233 — — Amortization of prior service cost/(credit) 7 16 (2,244) (2,244) Amortization of net actuarial loss 1,087 1,180 1,130 1,296 Net periodic benefit cost $ 1,647 $ 2,378 $ (497) $ 9 The amount of net periodic benefit cost is determined at the beginning of each year and generally only varies from quarter to quarter when a significant event occurs, such as a curtailment or a settlement. There were no such events in the first six months of 2021. In the second quarter of 2020, the Company recorded expense of $0.4 million related to curtailments and settlements. Service cost for defined benefit pension and postretirement plans are reported in the same line item as other compensation costs arising from services rendered by the pertinent employees during the period. Other components of net periodic benefit cost are included in the line item Other (income)/expense, net in the Consolidated Statements of Income.

Restructuring and Related Activities [Abstract]
Restructuring	Restructuring Restructuring costs in the first six months of 2021 were not significant. Restructuring costs in the first six months of 2020 were related to reductions in workforce at various AEC locations, principally in the United States, as well as related to discontinued operations at the Machine Clothing production facility in Sélestat, France. Since 2017, we have recorded $13.9 million of restructuring charges related to this action. There were no charges related to the impairment of assets for the periods presented. The following table summarizes charges reported in the Consolidated Statements of Income under “Restructuring expenses, net”: Three months ended June 30, Six months ended June 30, (in thousands) 2021 2020 2021 2020 Machine Clothing $ 10 $ 388 $ (58) $ 1,030 Albany Engineered Composites (48) 2,248 41 2,248 Corporate expenses 29 201 60 201 Total $ (9) $ 2,837 $ 43 $ 3,479 The table below presents the year-to-date changes in restructuring liabilities for 2021 and 2020, all of which are related to termination and other costs: (in thousands) December 31, Restructuring charges accrued Payments Currency translation /other June 30, Total termination and other costs $ 2,195 $ 43 $ (1,485) $ 11 $ 764 (in thousands) December 31, Restructuring charges accrued Payments Currency translation /other June 30, Total termination and other costs $ 2,042 $ 3,479 $ (1,410) $ (5) $ 4,106

Under this method, loss jurisdictions, which cannot recognize a tax benefit with regard to their generated losses, are excluded from the annual effective tax rate (AETR) calculation and their taxes will be recorded discretely in each quarter. In the second quarter of 2020, the Company recorded a net tax benefit of $1.5 million as a result of a US state tax audit settlement; the Company also recorded a net deferred tax expense of $1.0 million due to an adjustment of net operating losses related to settled audits. In the first quarter of 2020, the Company recorded a $1.8 million out-of-period charge related to developments in ongoing tax audits, which resulted in a corresponding decrease in deferred tax assets.

Contract Assets and Liabilities	Contract Assets and Liabilities Contract assets includes unbilled amounts typically resulting from sales under contracts when the cost-to-cost method of revenue recognition is utilized, and revenue recognized exceeds the amount billed to the customer. Contract assets are transferred to Accounts receivable, net when the entitlement to pay becomes unconditional. Contract liabilities include advance payments and billings in excess of revenue recognized. Contract liabilities are included in Accrued liabilities in the Consolidated Balance Sheets. Contract assets and Contract liabilities are reported on the Consolidated Balance Sheets in a net position on a contract-by-contract basis at the end of each reporting period. As of June 30, 2021 and December 31, 2020, Contract assets and Contract liabilities consisted of the following: (in thousands) June 30, December 31, Contract assets $ 114,097 $ 140,348 Allowance for expected credit losses (872) (1,059) Contract assets, net $ 113,225 $ 139,289 Contract liabilities $ 7,136 $ 8,206 Contract assets decreased $26.1 million during the six-month period ended June 30, 2021. The decrease was primarily due to invoicing to customers exceeding revenue recognized for satisfied performance obligations for contracts that were in a contract asset position. There were no credit losses related to our Contract assets during the six month periods ended June 30, 2021 and June 30, 2020. Contract liabilities decreased $1.1 million during the six-month period ended June 30, 2021, primarily due to revenue recognized from satisfied performance obligations exceeding amounts invoiced to customers that were in a contract liability position. Revenue recognized for the six-month periods ended June 30, 2021 and 2020 that was included in the Contract liability balance at the beginning of the year was $4.7 million and $2.1 million, respectively.

Inventory Disclosure [Abstract]
Inventories	Inventories Costs included in inventories are raw materials, labor, supplies and allocable depreciation and overhead. Raw material inventories are valued on an average cost basis. Other inventory cost elements are valued at cost, using the first-in, first-out method. The Company writes down the inventories for estimated obsolescence, and to lower of cost or net realizable value based upon assumptions about future demand and market conditions. If actual demand or market conditions are less favorable than those projected by the Company, additional inventory write-downs may be required. Once established, the original cost of the inventory less the related write-down represents the new cost basis of such inventories. As of June 30, 2021 and December 31, 2020, Inventories consisted of the following: (in thousands) June 30, 2021 December 31, 2020 Raw materials $ 59,627 $ 57,789 Work in process 45,436 40,416 Finished goods 15,602 12,273 Total inventories $ 120,665 $ 110,478

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill and intangible assets with indefinite useful lives are not amortized, but are tested for impairment at least annually. Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in each business combination. Our reportable segments are consistent with our operating segments. Determining the fair value of a reporting unit requires the use of significant estimates and assumptions, including revenue growth rates, operating margins, discount rates, and future market conditions, among others. Goodwill and other long-lived assets are reviewed for impairment whenever events, such as significant changes in the business climate, plant closures, changes in product offerings, or other circumstances indicate that the carrying amount may not be recoverable. To determine fair value, we utilize two market-based approaches and an income approach. Under the market-based approaches, we utilize information regarding the Company, as well as publicly available industry information, to determine earnings multiples and sales multiples. Under the income approach, we determine fair value based on estimated future cash flows of each reporting unit, discounted by an estimated weighted-average cost of capital, which reflects the overall level of inherent risk of a reporting unit and the rate of return an outside investor would expect to earn. In the second quarter of 2021, management applied the qualitative assessment approach in performing its annual evaluation of goodwill for the Company's Machine Clothing reporting unit and three AEC reporting units and

Under the Credit Agreement, $350 million of borrowings were outstanding as of June 30, 2021. The applicable interest rate for borrowings was LIBOR plus a spread, based on our leverage ratio at the time of borrowing. At the time of the last borrowing on June 30, 2021, the spread was 1.625%. The spread was based on a pricing grid, which ranged from 1.500% to 2.000%, based on our leverage ratio. Based on our maximum leverage ratio and our Consolidated EBITDA, and without modification to any other credit agreements, as of June 30, 2021, we would have been able to borrow an additional $350 million under the Agreement. The Credit Agreement contains customary terms, as well as affirmative covenants, negative covenants and events of default that are comparable to those in the Prior Agreement. The Borrowings are guaranteed by certain of the Company’s subsidiaries. Our ability to borrow additional amounts under the Credit Agreement is conditional upon the absence of any defaults, as well as the absence of any material adverse change (as defined in the Credit Agreement). On June 14, 2021, we entered into interest rate swap agreements for the period October 17, 2022 through October 27, 2024. These transactions have the effect of fixing the LIBOR portion of the effective interest rate (before addition of the spread) on $350 million of indebtedness drawn under the Credit Agreement at the rate of 0.838% during the period. Under the terms of these transactions, we pay the fixed rate of 0.838% and the counterparties pay a floating rate based on the one-month LIBOR rate at each monthly calculation date, which on June 16, 2021 was 0.08%. On November 27, 2017, we terminated our interest rate swap agreements, originally entered into on May 9, 2016, that had effectively fixed the interest rate on $300 million of revolving credit borrowings, in order to enter into a new interest rate swap with a greater notional amount, and the same maturity as the Credit Agreement. We received $6.3 million when the swap agreements were terminated, which has been fully amortized into interest expense through March 2021. On November 28, 2017, we entered into interest rate swap agreements for the period December 18, 2017 through October 17, 2022. These transactions have the effect of fixing the LIBOR portion of the effective interest rate (before addition of the spread) on $350 million of indebtedness drawn under the Credit Agreement at the rate of 2.11% during the period. Under the terms of these transactions, we pay the fixed rate of 2.11% and the counterparties pay a floating rate based on the one-month LIBOR rate at each monthly calculation date, which on June 16, 2021 was 0.08%, during the swap period. On June 16, 2021, the all-in-rate on the $350 million of debt was 3.735%. These interest rate swaps are accounted for as a hedge of future cash flows, as further described in Note 15. No cash collateral was received or pledged in relation to the swap agreements. Under the Credit Agreement, we are currently required to maintain a leverage ratio (as defined in the agreement) of not greater than 3.50 to 1.00 and minimum interest coverage (as defined) of 3.00 to 1.00. As of June 30, 2021, our leverage ratio was 1.08 to 1.00 and our interest coverage ratio was 15.02 to 1.00. We may purchase our Common Stock or pay dividends to the extent our leverage ratio remains at or below 3.50 to 1.00, and may make acquisitions with cash, provided our leverage ratio does not exceed the limits noted above. Indebtedness under the Credit Agreement is ranked equally in right of payment to all unsecured senior debt. We were in compliance with all debt covenants as of June 30, 2021.

Fair Value Disclosures [Abstract]
Fair-Value Measurements	Fair-Value Measurements Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. Accounting principles establish a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Level 3 inputs are unobservable data points for the asset or liability, and include situations in which there is little, if any, market activity for the asset or liability. We had no Level 3 financial assets or liabilities at June 30, 2021, or at December 31, 2020. The following table presents the fair-value hierarchy for our Level 1 and Level 2 financial and non-financial assets and liabilities, which are measured at fair value on a recurring basis: June 30, 2021 December 31, 2020 Quoted prices in active markets Significant other observable inputs Quoted prices in active markets Significant other observable inputs (in thousands) (Level 1) (Level 2) (Level 1) (Level 2) Fair Value Assets: Cash equivalents $ 26,848 $ — $ 17,508 $ — Other Assets: Common stock of unaffiliated foreign public company (a) 741 — 748 — Interest rate swaps — 261 — — Liabilities: Other noncurrent liabilities: Interest rate swaps — (9,270) — (12,714) (a) Original cost basis $0.5 million. Cash equivalents include short-term securities that are considered to be highly liquid and easily tradable. These securities are valued using inputs observable in active markets for identical securities. The interest rate swaps are accounted for as hedges of future cash flows. The fair value of our interest rate swaps are derived from a discounted cash flow analysis based on the terms of the contract and the interest rate curve, and is included in Other assets and/or Other noncurrent liabilities in the Consolidated Balance Sheets. Unrealized gains and losses on the swaps flow through the caption Derivative valuation adjustment in the Shareholders’ equity section of the Consolidated Balance Sheets. As of June 30, 2021, these interest rate swaps were determined to be highly effective hedges of interest rate cash flow risk. Amounts accumulated in Other comprehensive income are reclassified as Interest expense, net when the related interest payments (that is, the hedged forecasted transactions), and amortization related to the swap buyouts, affect earnings. Interest (income)/expense related to payments under the active swap agreements totaled $3.5 million for the six month period ended June 30, 2021, and $1.9 million for the six month period ended June 30, 2020. Additionally, non-cash interest income related to the amortization of swap buyouts totaled $0.3 million for the six month period ended June 30, 2021 and $0.4 million for the six month period ended June 30, 2020.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Asbestos Litigation Albany International Corp. is a defendant in suits brought in various courts in the United States by plaintiffs who allege that they have suffered personal injury as a result of exposure to asbestos-containing paper machine clothing synthetic dryer fabrics marketed during the period from 1967 to 1976 and used in certain paper mills. We were defending 3,617 claims as of June 30, 2021. The following table sets forth the number of claims filed, the number of claims settled, dismissed or otherwise resolved, and the aggregate settlement amount during the periods presented: Year ended December 31, Opening Number of Claims Claims Dismissed, Settled, or Resolved New Claims Closing Number of Claims Amounts Paid (thousands) to Settle or Resolve 2016 3,791 148 102 3,745 $ 758 2017 3,745 105 90 3,730 55 2018 3,730 152 106 3,684 100 2019 3,684 51 75 3,708 25 2020 3,708 152 59 3,615 57 2021 (As of June 30) 3,615 9 11 3,617 $ — We anticipate that additional claims will be filed against the Company and related companies in the future, but are unable to predict the number and timing of such future claims. Due to the fact that information sufficient to meaningfully estimate a range of possible loss of a particular claim is typically not available until late in the discovery process, we do not believe a meaningful estimate can be made regarding the range of possible loss with respect to pending or future claims and therefore are unable to estimate a range of reasonably possible loss in excess of amounts already accrued for pending or future claims. While we believe we have meritorious defenses to these claims, we have settled certain claims for amounts we consider reasonable given the facts and circumstances of each case. Our insurance carrier has defended each case and funded settlements under a standard reservation of rights. As of June 30, 2021, we had resolved, by means of settlement or dismissal, 37,957 claims. The total cost of resolving all claims was $10.4 million. Of this amount, almost 100% was paid by our insurance carrier, who has confirmed that we have approximately $140 million of remaining coverage under primary and excess policies that should be available with respect to current and future asbestos claims. The Company’s subsidiary, Brandon Drying Fabrics, Inc. (“Brandon”), is also a separate defendant in many of the asbestos cases in which Albany is named as a defendant, despite never having manufactured any fabrics containing asbestos. While Brandon was defending against 7,709 claims as of June 30, 2021, only twelve claims have been filed against Brandon since January 1, 2012, and a negligible amount of settlement costs have been incurred since 2001. Brandon was acquired by the Company in 1999, and has its own insurance policies covering periods prior to 1999. Since 2004, Brandon’s insurance carriers have covered 100% of indemnification and defense costs, subject to policy limits and a standard reservation of rights. In some of these asbestos cases, the Company is named both as a direct defendant and as the “successor in interest” to Mount Vernon Mills (“Mount Vernon”). We acquired certain assets from Mount Vernon in 1993. Certain plaintiffs allege injury caused by asbestos-containing products alleged to have been sold by Mount Vernon many years prior to this acquisition. Mount Vernon is contractually obligated to indemnify the Company against any liability arising out of such products. We deny any liability for products sold by Mount Vernon prior to the acquisition of the Mount Vernon assets. Pursuant to its contractual indemnification obligations, Mount Vernon has assumed the defense of these claims. On this basis, we have successfully moved for dismissal in a number of actions. We currently do not anticipate, based on currently available information, that the ultimate resolution of the aforementioned proceedings will have a material adverse effect on the financial position, results of operations, or cash flows of the Company. Although we cannot predict the number and timing of future claims, based on the foregoing factors, the trends in claims filed against us, and available insurance, we also do not currently anticipate that potential future claims will have a material adverse effect on our financial position, results of operations, or cash flows.
