Polyester fiber products

Polyester fiber pretreatment

Polyester fiber pretreatment including desizing scouring, relaxation, book type, such as alkaline deweighting process.The purpose is to remove the fiber manufacturing with oil, add stock, the color of dye weaving and contamination in the process of transportation and storage of oil and dust;To eliminate internal stress of fabric, the fabric relax;At the same time make polyester fiber molecular structure more uniform, dimensional stability, facilitate subsequent dyeing and finishing.

Polyester fiber dyeing

Polyester fiber dyeing is generally under the condition of high temperature and high pressure, polyester macromolecular intense thermal motion occurs, disperse dye by dispersion, adsorption and diffusion into the polyester fiber dyeing in the process.Disperse dye rely mainly on hydrogen bonding and molecular inter-atomic forces combined with fiber.Add in the process of dyeing of disperse dye and other auxiliaries can be appropriately increased both the solubility of disperse dye;Improve the dispersion stability of dye;Promote the disperse dye adsorption on the surface of fiber;For the fiber plasticizing or increase the degree of swelling, speed up the diffusion of disperse dye on the fiber.
