Polyester Auxiliaries

Polyester fiber is the common name of PET fiber. Based on PTA or DMT and MEG, this fiber is made from a fiber-forming high polymer manufactured by esterification or ester exchange and condensation reaction and processed by spinning and post-processing. This fiber is the largest kind of man-made fiber and is massively used in manufactured fashion fabrics and industrial products. Polyester fiber textiles have excellent wrinkle resistance and conformity and therefore are perfect for outdoor goods such as sportswear, jackets/coats, bags and tents.

Polyester Pretreatment

Preprocessing of polyester fiber includes processes such as desizing & scouring, relaxation, pre-setting and de-weighting. The purpose is to remove the oil added when manufacturing fibers, slurry added during weaving, staining dyes and oils, and dust attached during transportation and storage to eliminate forces inside the textile and enable the textiles to relax. In the meantime, this also makes a more level polyester fiber molecular structure and stable size and facilitates the following dyeing and finishing processes.

Polyester Dyeing

Generally, polyester fiber dyeing refers to the process where under high temperature and high pressure, large molecules of polyester fiber generate fierce thermal motion and disperse dyes through dispersion, absorption, and diffusion, causing them to enter the polyester fibers to finish dyeing. The disperse dye mainly relies on the force between the hydrogen bond and molecules to combine with fibers. Adding auxiliaries such as disperse leveling agents during the dyeing process can properly increase the solubility of dispersion dyes, upgrade dyes' dispersion stability, enhance the dispersion dyes' absorption into the fiber surface and run plasticization or increase the swelling of fibers to accelerate the diffusion speed of the dispersion dyes into the fibers.
