ASTM D7507-23 PDF

Overview

ASTM D7507-23 is the internationally recognized standard specification for woven high stretch fabrics used in apparel. Published by ASTM International, this document sets forth the performance requirements for woven fabrics containing high levels of elastic fibers, primarily used in clothing where flexibility and stretch are essential. The standard ensures that these high stretch fabrics meet specific criteria for durability, safety, and quality, providing a basis for both manufacturers and purchasers to evaluate and select suitable textiles for fashion and performance garments.

Key Topics

• Performance Requirements: Specifies how woven high stretch fabrics should perform in essential aspects such as stretch, dimensional stability, colorfastness, and flammability.
• Testing Methods: References widely accepted ASTM and AATCC test methods for evaluating:
  • Stretch and recovery
  • Dimensional change after laundering and dry cleaning
  • Colorfastness to laundry, dry cleaning, bleaching, perspiration, crocking, light, and ozone
  • pH levels and fabric weight
  • Flammability (in alignment with 16 CFR 1610)
• Quality Control: Defines acceptance criteria for textile lots, sampling processes, and reporting of physical and chemical properties.
• Purchasing Agreements: Allows flexibility for buyers and suppliers to mutually agree on modifications to requirements for specific aesthetics or end uses.

Applications

ASTM D7507-23 is vital for professionals in the apparel industry, including textile manufacturers, fashion designers, sourcing specialists, and quality assurance personnel. Its value and practical applications include:

• Garment Manufacturing: Ensures that sportswear, fashion apparel, uniforms, and other stretch-based garments perform reliably in terms of fit, comfort, and appearance after repeated use and care cycles.
• Fabric Sourcing: Enables buyers to specify and verify compliance with international standards for stretch performance, durability, and color retention when selecting high stretch woven fabrics.
• Product Development & Innovation: Provides a standardized baseline for developing new woven stretch fabrics with enhanced performance or targeted end-use applications.
• Regulatory Compliance: Facilitates adherence to governmental and trade regulations concerning flammability and consumer safety, especially in markets with stringent import requirements.
• Dispute Resolution: Acts as an industry-accepted reference in case of quality disputes between buyers and suppliers.

Related Standards

ASTM D7507-23 references and is complemented by additional standards and test methods, including:

• ASTM D123: Terminology Relating to Textiles
• ASTM D3107: Test Methods for Stretch Properties of Fabrics Woven from Stretch Yarns
• ASTM D3775: Test Method for End (Warp) and Pick (Filling) Count of Woven Fabrics
• ASTM D3776: Test Methods for Mass Per Unit Area (Weight) of Fabric
• AATCC Methods: A suite of colorfastness, dimensional change, and pH tests (e.g., AATCC TM8, TM135, TM158, TM16)
• 16 CFR 1610: Standard for Flammability of Clothing Textiles

These documents, along with ASTM D7507-23, form a comprehensive framework for assessing and specifying the quality and performance of woven high stretch fabrics for use in apparel.
