All you need to know about Polyester Cationic Dyeable Yarn

Polyester cationic dyeable yarn is a special polyester fibre that can be coloured with cationic dye, unlike ordinary polyester yarn. This yarn is a special polyester fibre, not only is it a very light weight yarn, but contains both nylon and polyester which makes it very durable. The polyester cationic dyeable yarn is slightly firmer than natural yarn, making it ideal for knitting, embroidery and other decorative applications.

Polyester cationic dyeable yarn's upgraded and improved

The commonly used polyester cationic dyeable yarn is a new polyester product spun by introducing dimethyl isophenate with polar SO3Na into polyester slices. Its appearance is no different from ordinary polyester yarn, but because of the use of ion modification, it not only greatly improves the color absorption performance of the fiber, but also reduces the crystallinity and makes dye molecules easy to penetrate. Make the fiber easy to stain, improve the color absorption rate, hygroscopicity is also improved; This fiber not only ensures cationic easy dyeing, but also increases the micropore of the fiber, improves 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.

Methods to improve dyeing property of polyester

In order to improve the dyeing property of polyester, from the perspective of molecular structure, increasing the degree of molecular chain porosity will facilitate the entry of dye molecules. The main methods to improve dyeing properties are:

(1) copolymerization with a large molecular volume of chemical platform;

(2) Spinning by mixing with plasticizing compounds;

(3) Introduce groups with ether bond and good affinity for dispersive dyes.

The polyester resin modified by copolymerization method has low melting point and crystallinity, and its thermal and mechanical properties are damaged to a certain extent.

Polyester cationic dyeable yarn's practical advantages

Polyester cationic dyeable yarn can be compared with natural fabric in terms of wearing comfort and bright dyeing, and its price is lower than that of natural silk, which can produce high added value.
