What is Antistatic agent? Antistatic agents are chemical additives added to resins or coated on the surfaces of polymer materials to prevent or dissipate static charge. Antistatic agents themselves lack free electrons and belong to the category of surfactants. They achieve their antistatic effect by Read More
What are the conditions for wool pretreatment?As a high-quality natural fiber, wool requires meticulous pretreatment processes to ensure the quality of the final product. Pretreatment primarily includes washing, degreasing, and carbonizing. Each step requires precise control to achieve optimal resul Read More
In the previous article, we discussed the influence of fiber, dye selection, and dyeing process control on rubbing fastness. In this second part, we focus on finishing and physical methods—the “remediation” and “enhancement” steps that can significantly boost both wet and dry rubbing fastness.3. Fin Read More
Precautions for Using Pigment Printing ThickenersStorage and HandlingProper storage is crucial for maintaining the quality of pigment printing thickeners. Store them in a cool, dry place away from direct sunlight and extreme temperatures. High temperatures can cause the thickener to deteriorate, whi Read More
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. Ensure adequate fabric pretreatment: Fabr Read More
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
