ASTM D2057-05(2022)

Standard Test Method for Colorfastness of Zippers to Laundering

SIGNIFICANCE AND USE
5.1 Test Method D2057 is useful for testing to determine if the degree of alteration in shade is satisfactory for the intended end-use and for determining if unacceptable staining of color into adjacent fabric will occur.
Note 1: For guidance in evaluating the results of this method, refer to Practice D3692.  
5.2 This test method is considered satisfactory for acceptance testing of commercial shipments because the method has been used extensively in the trade for acceptance testing.  
5.2.1 If there are differences of practical significance between reported test results for two laboratories (or more), comparative tests should be performed to determine if their is a statistical bias between them, using competent statistical assistance. As a minimum, the test samples should be used that are as homogeneous as possible, that are drawn from the material from which the disparate test results were obtained, and that are randomly assigned in equal numbers to each laboratory for testing. Other materials with established test values may be used for this purpose. The test results from the two laboratories should be compared using a statistical test for unpaired data, at a probability level chosen prior to the testing series. If a bias is found, either its cause must be found and corrected, or future test results must be adjusted in consideration of the known bias.  
5.3 The method(s) in this standard along with those in D2051, D2052, D2053, D2054, D2058, D2059, D2060, D2061, and D2062 are a collection of proven zipper test methods. They can be used as aids in the evaluation of zippers without the need for a thorough knowledge of zippers. The enumerated test methods do not provide for the evaluation of all zipper properties. Besides those properties measured by means of the enumerated test methods there are other properties that may be important for the satisfactory performance of a zipper. Test methods for measuring those properties have not been published either because...
SCOPE
1.1 This test method covers the determination of alteration in shade and of staining under conditions similar to that experienced in domestic washing of zipper stringers. This test method is applicable to the textile portion of zipper stringers that utilize tapes made of cotton, linen, or manufactured organic fibers, and to combinations thereof.  
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview

ASTM D2057-05(2022) - Standard Test Method for Colorfastness of Zippers to Laundering specifies procedures for assessing the resistance of zipper textiles to color changes and staining during laundering. Developed by ASTM, this standard ensures reliable evaluation of zippers used in garments and household products by simulating home laundry conditions. It is widely recognized within the textile industry for quality control, acceptance testing, and product development, helping manufacturers determine the suitability and durability of zippers for their intended end use.

Colorfastness is a vital property, as it affects the appearance and function of textile products. By following this standard, textile professionals can minimize the risk of zipper staining or fading, ensuring customer satisfaction and product longevity.

Key Topics

• Scope and Applicability

  • Targets zippers constructed with tapes from cotton, linen, or other manufactured organic fibers, including blended tapes.
  • Tests alteration in color shade and staining under laundering conditions simulating domestic washing.

• Test Methodology

  • Involves laundering zipper specimens in contact with a multifiber test cloth using standard washing and drying equipment.
  • Grading is performed for color change (using the AATCC Gray Scale) and for staining (using the AATCC Chromatic Transference Scale).
  • Laundering conditions cover various temperatures and use of both chlorine and nonchlorine household bleaches.

• Significance and Use

  • Assesses if the color alteration and staining levels are acceptable for the end use of the product.
  • Useful for evaluating if color transfer to adjacent materials or significant color fading may occur.

• Acceptance and Statistical Validity

  • Approved for acceptance testing in commercial shipments due to its widespread industry usage.
  • Guidelines provided for resolving differences between laboratory results, including statistical comparison procedures.

Applications

• Textile and Apparel Manufacturing

  • Used to qualify zippers for garments, uniforms, and care-labeled textiles that require frequent laundering.
  • Helps ensure product quality by verifying that zippers maintain color integrity and do not cause unwanted staining to garments.

• Quality Control and Procurement

  • Integral part of incoming material inspections and batch testing for zipper suppliers and garment manufacturers.
  • Supports supply chain requirements for consistent product performance.

• Product Development

  • Applied in R&D phases to select zipper materials with high colorfastness for new designs and textile innovations.

• Performance Specification

  • Assists brands and retailers in defining product requirements and setting pass/fail criteria for colorfastness and staining of zipper components.
