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

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

What problems might arise during high-temperature dyeing?Under high-temperature and high-pressure conditions, the average kinetic energy of polyester fiber macromolecular chains rapidly increases. Above 80°C, polyester fibers transition from a frozen state to a vitrified state. As the temperature co Read More

What is the principle behind affinity-based leveling dyeing?When the leveling agent's affinity for the fiber is greater than the dye's affinity for the fiber, the leveling agent and dye compete for dyeing. The leveling agent preferentially binds to the fiber, occupying dyeing sites on the fiber, hin Read More

How do printing and dyeing plants use coagulation and sedimentation to treat wastewater? Coagulation and sedimentation can effectively remove suspended solids (SS), colloidal particles, and some dyes and auxiliaries from printing and dyeing plant wastewater. The key to this process is the use of che Read More
