Basis of Presentation (Policies)	Sep. 28, 2013
Accounting Policies [Abstract]
Basis of Presentation	The accompanying consolidated financial statements reflect the consolidated operations of the Company and have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) as defined by the Financial Accounting Standards Board (“FASB”) within the FASB Accounting Standards Codification (“ASC”). In the opinion of management, the accompanying consolidated financial statements contain all adjustments, which include normal recurring adjustments, necessary to present fairly the consolidated results for the periods presented. The accompanying consolidated financial statements should be read in conjunction with the consolidated financial statements included in the Polymer Group, Inc. Annual Report on Form 10-K for the year ended December 29, 2012.
Fiscal Period	The Company's fiscal year is based on a 52 week period ending on the Saturday closest to each December 31. Therefore, the financial results of 53-week fiscal years, and the associated 14-week quarters, will not be comparable to the prior and subsequent 52-week fiscal years and the associated quarters having only 13 weeks. The three months ended September 28, 2013 and September 29, 2012 each contain operating results for 13 weeks.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In February 2013, the FASB issued Accounting Standards Update No. 2013-02, "Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income" ("ASU 2013-02"), which requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, ASU 2013-02 requires an entity to present, either on the face of the income statement or in the notes to the financial statements, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts, an entity is required to cross-reference to other disclosures required under GAAP that provide additional detail about those amounts. The amendments in ASU 2013-02 do not change the current requirements for reporting net income or other comprehensive income in the financial statements. ASU 2013-02 is effective prospectively for reporting periods beginning after December 15, 2012. The adoption of this guidance concerns disclosure only and does not have an impact on the Company's financial results. See Note 11 for additional information. In July 2013, the FASB issued Accounting Standards Update No. 2013-11, "Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists" ("ASU 2013-11"), which requires an unrecognized tax benefit, or a portion of an unrecognized tax benefit, be presented in the financial statements as a reduction of a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax position is disallowed. In situations where a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction or the tax law of the jurisdiction does not require, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. ASU 2013-11 is effective prospectively for reporting periods beginning after December 15, 2013, with retroactive application permitted. The Company is currently assessing the potential impacts, if any, on its financial results.

Disclosure of accounting policy for determining an entity's fiscal year or other fiscal period. This disclosure may include identification of the fiscal period end-date, the length of the fiscal period, any reporting period lag between the entity and its subsidiaries, or equity investees. If a reporting lag exists, the closing date of the entity having a different period end is generally noted, along with an explanation of the necessity for using different closing dates. Any intervening events that materially affect the entity's financial position or results of operations are generally also disclosed.
