What Are the Types of Color Fastness Testing for Fabrics?
Color fastness testing evaluates how well fabrics resist fading or bleeding under conditions like washing, rubbing, light exposure, and perspiration. Key tests include rubbing fastness, washing fastness, light fastness, perspiration fastness, and sublimation fastness. These tests ensure textiles maintain color integrity, prevent health risks, and meet quality standards. Learn about different testing methods and equipment used in the textile industry.
Analysis of Pilling Influencing Factors and Testing Methods
Pilling testing plays a vital role in textile quality control, helping manufacturers evaluate and improve the wear performance of fabrics. Through the use of advanced instruments like ICI Pilling Box Test Method (GT-C18) , Martindale Abrasion Test Method (GT-C13B) , and Random Tumble Pilling Test Method (GT-C19A) , laboratories can conduct precise and standardized assessments, ensuring that final textile products deliver superior appearance, comfort, and longevity.

How to Choose Light Fastness Tester: Water-Cooled and Air-Cooled
Choosing between water-cooled and air-cooled light fastness testers depends on precision needs, budget, and application. Water-cooled testers (like GESTER GT-3000) offer superior spectral accuracy and stability for rigorous standards (e.g., automotive, coatings). Air-cooled models (like GESTER GT-D02A-1) provide energy efficiency and easier installation for routine QC. This guide compares cooling methods, features, and applications to help you select the optimal tester.
What Are the Test Methods for Fabric Bursting Strength?
Fabric bursting strength measures resistance to rupture under concentrated load. Three primary test methods are used:

Ball Burst Method (ASTM D3787): Steel ball penetration for textiles/films using testers like GT-C02-2.

Hydraulic Method (ISO 13938.1): Fluid pressure on rubber diaphragm for industrial fabrics via GT-C12A.

Pneumatic Method (ISO 13938.2): Compressed air for breathable materials tested with GT-C12B.
Results are influenced by raw materials, yarn properties,
