HT Fine Textile Chemical Auxiliary Agent

High temperature levelling agent , soluble in water and general organic solvents, has excellent dye dispersibility, early retarding property and can be used with dyes at the same time. The performance of high temperature levelling agent is mainly measured by three indexes: retarding, dispersivity and migration. Retarding refers to dyeing rate, or dyeing speed. The faster the dyeing speed is, the easier the fabric is uneven. While it shouldn’t completely prevent the fabric from being colored, which will affect the final dyeing rate. Dispersivity is the ability to distribute dyes evenly in water bath so that the dye can be evenly absorbed by fiber or fabric. Migration refers to the transfer of disperse dyes to the lower concentration of the dye through levelling agent.   High temperature and high pressure dyeing is an important dyeing method of polyester fiber. On the one hand, because of dyeing properties of polyester fiber, it has basic requirements for high temperature levelling a...

In printing and dyeing process, how to avoid uneven phenomenon is one of the important indexes of printing and dyeing.  Levelling agent  is the auxiliary that can be used in the fiber and makes the fabric dyes evenly. One of the functions of levelling agent is making the dyes slowly absorbed by the fibre. The second function of  dyeing agent  is when it is the uneven dyeing, the dark part of the dye moves towards the light part, and finally, achieve levelling. Therefore, retarding and migration are the two most important functions of levelling agent. Levelling agent is the auxiliary that has affinity to fiber and dyes, which can promote dye exhaustion, so that they can quickly penetrate into the fiber, achieving dispersion and obtain uniform dyeing effect. It can promote a variety of fabric surface levelness, improve damaged tip of wool fiber, make the wool in its original quality at 85℃. It should be noted that it can not be combined with other anionic additives, a...
