Overview
SIST EN ISO 13936-1:2004 specifies a standard test method for determining the slippage resistance of yarns at a seam in woven fabrics, specifically using the fixed seam opening method. Developed by the International Organization for Standardization (ISO) and adopted by the Slovenian Institute for Standardization (SIST), this standard provides a reliable way to assess how fabric thread systems resist slippage when sewn, an important parameter in textile product quality and durability. The test is crucial in ensuring that woven textiles perform as expected during usage, particularly at seams where slippage can impact garment and textile product performance.
Key Topics
- Scope of Application: Focuses on woven fabrics, excluding stretch and industrial fabrics such as belting.
- Test Principle: Measures the force required to produce a specified gap (seam opening) at a sewn seam using a constant-rate-of-extension (CRE) tensile testing machine.
- Sampling and Test Preparation: Emphasizes representative sample selection, proper cutting, and sewing procedures to avoid bias from damaged or edge material.
- Test Equipment: Recommends CRE tensile testing machines, specific clamping devices, suitable sewing threads, and lockstitch sewing machines for sample preparation.
- Calculation and Reporting: Stresses accuracy in recording the seam opening and corresponding slippage resistance force, reporting results separately for warp and weft directions.
- Atmosphere and Conditioning: Requires conditioning specimens in standardized laboratory atmospheres for reliable and repeatable results.
Applications
SIST EN ISO 13936-1:2004 is highly relevant to various sectors within the textile industry, textile testing laboratories, and manufacturers:
- Quality Control: Ensures that garments, furnishings, and technical textiles meet minimum performance requirements for seam integrity and yarn slippage resistance.
- Product Development: Assists fabric and garment designers in selecting materials and seam constructions that will perform reliably in end-use.
- Compliance Testing: Supports meeting regulatory or customer requirements for fabric and seam durability, especially where seam slippage could lead to product failure.
- Inter-Laboratory Comparison: Provides a harmonized test method for consistent results between different organizations and countries.
Related Standards
For comprehensive textile testing and quality assurance, the following standards are complementary to SIST EN ISO 13936-1:2004:
- ISO 139 - Textiles - Standard atmospheres for conditioning and testing
- ISO 4915 - Textiles - Stitch types - Classification and terminology
- ISO 7500-1 - Metallic materials - Verification of static uniaxial testing machines - Part 1: Tension/compression testing machines
- ISO 6330 - Textiles - Domestic washing and drying procedures for textile testing
- ISO 3175-2 - Textiles - Professional care, drycleaning and wetcleaning of fabrics and garments
By adhering to SIST EN ISO 13936-1:2004, organizations improve product reliability, reduce failures due to seam slippage, and enhance customer satisfaction in textile goods. This standard is essential for manufacturers and testing bodies seeking to demonstrate quality through internationally recognized slippage resistance testing of woven fabrics.
