On June 19, 2009, the National Technical Committee on Textiles of Standardization Administration of China issued GB/T 4802.4—2009, *Textiles—Determination of fabric propensity to surface fuzzing and to pilling—Part 4: Random tumble method* (hereinafter referred to as "this Standard"), which came…
In daily life, garments often develop fuzz or pills on specific areas or across the entire fabric after a period of wear; consequently, fabric pilling resistance testing has become increasingly important and widespread, as it directly affects the aesthetic appeal…
Moisture permeability is one of the key performance indicators of textiles. With increasing emphasis on moisture and water resistance, textiles with superior moisture-blocking properties (i.e., lower moisture permeability) have become a focus in textile development and use, receiving growing attention…
With the development of the times, people's demands for clothing have gone beyond just comfort; they also require clothing to have certain functions. Moisture permeability is both an important factor affecting comfort and an indicator of functionality. The testing of…
With improvements in living standards and advancements in technology, functional textiles offering water, oil, and stain resistance have garnered increasing attention from consumers. The ability of textiles to resist surface wetting by various liquids—such as water, oil, alcohol, blood, and…
There are currently two main types of waterproof fabric designs. The first is laminated waterproof fabric, created by bonding ordinary fabric with a special adhesive through a lamination process to form a waterproof composite; this structure may consist of two…
The international standard ISO 6330:2021 "Textiles—Home washing and drying procedures for testing" (hereinafter referred to as the "new standard") was published and implemented in November 2021. This standard was jointly developed by ISO/TC 38/SC2 and CEN/TC 248 under the technical…
Air permeability refers to a fabric's ability to allow air to pass through it, a characteristic that directly influences its performance in apparel. For instance, fabrics intended for summer wear require high air permeability, whereas winter fabrics need lower permeability…
A washing fastness tester is an essential textile testing machine for assessing color fastness to washing, ensuring the fabric stays colored and won't stain when washed. It simulates the actual washing process and can be used to measure washing fastness…
As the world's most important natural textile raw material, the quality of cotton fiber directly determines the performance and value of yarns, fabrics, and finished textile products. Sensory inspection of cotton fiber is a traditional yet vital process that relies…
The United States is the primary export destination for Chinese textile and apparel products and the world's largest consumer market for textiles. Products exported to the U.S. must comply with local laws and regulations; in particular, there are strict U.S.…
Aromatic polyamide fibers are fibers composed of linear macromolecules formed by aromatic groups linked by amide or imide bonds. At least 85% of the amide or imide bonds are directly connected to two aromatic rings, and when imide bonds are…
