Let us know more about Polyester Cationic Dyeable Yarn

Polyester cationic dyeable yarn full name polyester cationic dyeable yarn, chemical name: polybutylene terephthalate (elastic polyester); cationic dyed polyester; Abbr. PBT, also known as CD in the factory. polyester cationic dyeable yarn belongs to denatured/modified polyester and can be dyed with cationic dye at 110℃.

The modification method of polyester cationic dyeable yarn

The modification method of polyester cationic dyeable yarn is to copolymerize polyester dyeing agents, such as dimethyl m-5-sulfonate sodium (commonly known as trimonomer, English abbreviation SIPM) and polyester. After copolymerization, sulfonate groups are introduced into the polyester molecular chain, which can be dyed with cationic dyes. The dyed fabric has bright colors, high dye absorption rate, and greatly reduces the discharge of printing and dyeing wastewater. Copolymerized polyester slicing can also increase the anti-static, anti-pilling and hygroscopic properties, which is one of the main methods to improve polyester dyeing properties in recent years. The microfiber with high dyeing depth can be made by using the block copolymer of 4 parts of the cationic dyeable polyester containing sulfonate group and 1 part of ethylene glycol/polyethylene glycol/sulfonic acid sodium phthalate/terephthalic acid in Unijica company of Japan. BHET(hydroxyethyl terephthalate) is copolymerized with cationic active agent and a small amount of denaturant before or during spinning. The spinnability of the polymer is improved by making it into random linear polymer. The modified polyester can not only be dyed with cationic dyes, but also has pilling resistance and improved wrinkle recovery.

Characteristic of polyester cationic dyeable yarn

The polyester cationic dyeable yarn has a lower melting point and crystallinity than the ordinary polyester, which makes the dye molecules easy to penetrate, and makes the fiber easy to stain, improve the color absorption rate, and improve the moisture absorption. The molecular weight, crystallinity and strength of polyester cationic dyeable yarn are lower than that of ordinary polyester. The Young's modulus of polyester cationic dyeable yarn is 10%~30% lower than that of ordinary polyester, so its fabric is softer than ordinary polyester fabric. In addition, compared with ordinary polyester, polyester cationic dyeable yarn has a much higher alkaline hydrolysis rate. Therefore, the alkali decrement rate of polyester cationic dyeable yarn fabric is much higher than that of ordinary polyester fabric at the same temperature. Polyester cationic dyeable yarn can not only ensure the cationic easy dyeing, but also increase the micropores of the fiber, improve the dyeing rate of the fiber, air permeability, moisture absorption, so as to further adapt to the polyester fiber silk; By imitation silk can make the fabric soft, breathable, comfortable, anti-static, normal temperature and pressure can be dyed; By cationic modification of multifunctional wool-like, can make the fabric feel soft, anti-static, anti-pilling, normal temperature and pressure and wool co-dyeing.
