What are raw materials for colour fastness to ozone production?

If this question is asked, you will think about cost, security and performance of colour fastness to ozone . A producer is expected to confirm the source of raw material, decrease the cost for raw material and apply innovative technology, in order to improve the performance-cost ratio. Now most of the manufacturers would examine their raw materials prior to processing. They may even invite third parties to check the materials and issue test reports. Stable partnerships with raw material suppliers are of great relevance to the colour fastness to ozone makers. This usually means that their raw materials will be guaranteed by price, quality and quantity.

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.
How to Know the Fabric Shrinkage Test for Your Projects
Master fabric shrinkage testing with this definitive guide. Understand causes of shrinkage, industry standards (ISO, GB, AATCC), step-by-step testing methods using Wascator equipment, and strategies to minimize shrinkage for superior garment quality and customer satisfaction.
Water Resistance Testing Standards and Methods
Textile water resistance testing evaluates fabrics through three primary methods: hydrostatic pressure (measuring water penetration resistance), spray rating (assessing surface water repellency), and water repellency tests (quantifying water absorption). Hydrostatic pressure testing is critical for high-performance applications like outdoor apparel and diving gear, while spray rating evaluates surface staining for rainwear. Water repellency tests, such as the Bundesmann method, determine overall

What Are the ISTA Standard Tests and ISTA Testing Equipment?
ISTA (International Safe Transit Association) standard tests are globally recognized transportation packaging test procedures designed to evaluate the safety and reliability of products and their packaging throughout the logistics chain. By simulating real-world transportation conditions such as drops, vibration, impact, stacking, and compression, ISTA testing helps identify potential packaging weaknesses before products enter large-scale distribution. ISTA testing equipment—including drop testers, vibration testers, incline impact machines, and compression testers—plays a critical role in accurately reproducing these conditions under laboratory settings. Proper selection and use of ISTA-compliant equipment enable manufacturers to reduce transportation damage, lower return costs, enhance packaging design, and improve customer confidence in product quality and logistics safety.
