Physical Performance
Fabric Tensile Breaking Strength Test
- Test Purpose: To determine the maximum force (tensile strength) a fabric can withstand when stretched at a constant rate until fracture, as well as the elongation at break. This indicator directly reflects the sturdiness and durability of fabrics, serving as a fundamental physical parameter for textile quality assessment.
- Applicable Scope: Applicable to all types of textiles, especially garments frequently subjected to tension (such as trousers, sportswear, and workwear), home textiles (such as bed sheets and curtains), and industrial textiles (such as tents and safety belts).
- Key Standards: Testing is mainly conducted in accordance with GB/T 3923.1 Textiles: Tensile Properties of Fabrics — Part 1: Determination of Breaking Strength and Breaking Elongation (Strip Method) or GB/T 3923.2 (Grab Method).
Fabric Dimensional Stability Test (Shrinkage Rate)
- Test Purpose: To evaluate the dimensional changes in length and width of fabrics after care processes such as washing, dry cleaning and ironing, which are mostly shrinkage and occasionally elongation. This test is designed to predict the deformation of finished garments during consumer use and prevent clothes from shrinking or distorting after washing.
- Applicable Scope: Widely used for garments made of shrink-prone fibers including cotton, linen, and viscose (e.g., shirts, T-shirts, and jeans), as well as home textiles such as quilt covers and fitted sheets. It is a mandatory testing item for e-commerce sales and export trade.
- Key Standards: Implemented in accordance with the series standards of GB/T 8628 (Test Preparation Procedures), GB/T 8629 (Laboratory Washing and Drying Procedures) and GB/T 8630 (Determination of Dimensional Changes).
Fabric Abrasion Resistance Test
- Test Purpose: Simulate repeated friction on fabrics during daily use, such as hip contact with chairs and elbow abrasion, to determine the abrasion resistance cycles before surface damage, yarn breakage, fuzzing or pilling occurs. This parameter is used to evaluate the wear durability of fabrics.
- Applicable Scope: Especially applicable to frequently used textiles, including jeans, sofa fabrics, carpets, workwear, school uniforms and mattress fabrics.
- Key Standards: The primary applicable standard is GB/T 21196 Textiles – Determination of Abrasion Resistance of Fabrics by the Martindale Method. GB/T 3920, though formulated mainly for color fastness, also covers friction performance testing.
