ASTM D2057-05(2022)

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.
