How to test the solid content of additives?Solid content (solids content) is a commonly used indicator for testing liquid additives. It generally reflects the effective content of the additive and can be used as a reference for comparing multiple additives or for batch comparison testing. However, s Read More
How to Improve Wet and Dry Rubbing Fastness? Improving wet and dry rubbing fastness (rubbing fastness) of textiles is a common quality issue, especially for dark fabrics (such as black and navy) and cellulosic fibers (such as cotton). This primarily involves dye selection, process optimization, and Read More
How to improve the waterproofing ability of fluorine-free water repellents?1. Optimizing the finishing processOptimizing the finishing process is a very direct and important step in improving the waterproofing effectiveness of fluorine-free water repellents.

Silicone defoamers have a wide range of applications, including metalworking, papermaking, wastewater treatment, pesticides, and petroleum refining. Defoamers are used in the printing and dyeing industry in two ways: 1. Direct addition during the wet finishing process;2. Pre-addition to surfactant-b Read More
How to choose a refining agent?1. Refining agentsRefining agents are mainly divided into two categories:(1) Used for cotton and linen textiles, their function is to assist caustic soda in removing symbiotic substances (pectin, wax, lignin, pigments, cottonseed shells, etc.) in cotton or linen fibers Read More
How can silicone oil be used to achieve different fabric feel? Simply put, by selecting silicone oils of different types, molecular structures, and modified groups, and adjusting the application process parameters, a wide range of hand feels can be achieved, from extremely soft and smooth to elastic Read More
What are the uses and functions of chelating dispersants? Chelating dispersants are multi-purpose organic chelating agents that perform dual functions by complexing metal ions and dispersing inorganic precipitates. They are widely used in textile printing and dyeing, water treatment, and industrial Read More
