Polyester Draw Texturing Yarn Cationic

Polyester Draw Texturing Yarn Cationic is a new type of polyester product which is spun by dimethyl isophthalate with SO3Na into polyester. Its appearance is no different from that of ordinary Polyester Yarn. However, the ionic modified polyester filament not only improves the color absorption of the fiber greatly, but also reduces the crystallinity and makes the dye molecules permeable easily. The fibers are easy to dye, the absorptivity is improved, and the water-absorbing is also improved. This kind of fibers can not only ensure cationic dyeability, but also increase the micropore of the fibers, and improve the dyeing rate, air permeability and moisture absorption of the fibers, the fabrics can be soft, air permeable, comfortable, antistatic and dyeable at room temperature and atmospheric pressure. Fabrics made of cationic yarn have the following characteristics when dyed with cationic dyestuff:

1. Bright tone, good deep dyeing;

2. High water-absorbing;

3. Good fastness to sunlight and fading;

4. Good stability in high temperature dyeing bath;

5. Dye stability is high when pH value changes in dyeing bath.
