1. Purpose and Scope 1.1 This test method aims to evaluate the resistance of fabrics and other flexible materials to abrasion. 2. Principle 2.1 An impeler (rotor) drives an unfettered fabric specimen along a zigzag course in a generally circular orbit within a cylindrical chamber, causing it to repeatedly impinge on the walls and abradant…

Air permeability tester is an instrument. It measures a material’s permeability. It is widely used in the textile industry to test fabric porosity. You can also use it on other materials, like paper, plastic film, and leather. The tester works by applying a constant pressure across the test material. It measures the air flow rate…

ISO 13934-1 and ISO 13934-2 differ in their test method and scope. They are both textile tensile tests. Test method ISO 13934-1: The strip method tests the fabric’s width in a tensile fixture. It is for testing loose or wet fabrics. The fixture holds the sample in a low-stress area. This causes the sample to…

Why should I choose ASTM D7984 for Cool Feel Fabrics? They chose ASTM D7984 for Cool Feel fabric testing. It measures a textile’s thermal conductivity and fugacity. This quantifies a fabric’s insulation and conductivity. This method uses a modified transient planar heat source (MTPS) method. A single-sided heat sensor heats the sample surface for 1-3…

Tearing, or fabric tearing, happens when a load affects the fabric’s local yarns. In use, clothes can get caught on objects. This can pull off the local yarn in the fabric. It can form a strip or triangular tear, which is a type of fabric fracture. Definition of fabric tear strength Fabric tear strength is…

Hydrostatic pressure index is one of the important indexes of waterproof and moisture permeable fabrics. Hydrostatic pressure refers to the resistance encountered by the water through the fabric, under standard atmospheric pressure conditions, the fabric to withstand a continuous rise in water pressure, until the back of the fabric seepage water droplets, at this time,…

Colour fastness to washing is a textile’s ability to keep its original colour after washing under the specified conditions. This means they will not fade or change colour. It is an important indicator of the quality of printing and dyeing. The unqualified discolouration or staining affects the product’s look and performance. It also harms the…

Printing and dyeing, or dyeing and finishing, is a kind of textile processing. It is also the general name for pre-treatment, dyeing, printing, finishing, and washing. Dyeing and finishing Dyeing and finishing is the chemical treatment of textiles (fibres, yarns, and fabrics). It is often called printing and dyeing. They combine it with spinning, weaving,…
