what is cationic polyester?
Cationic polyester is short for cationic dyeable polyester,and some factories are also referred to as CD.
It is considered a modified polyester fiber. There are cationic dyeable sulfonic acid groups within the fabric structure, allowing for improvement in its dyeability, and has high degree of staining power. Only a small amount of dye is needed to get a rich and deep color, enhancing the vividness of the dye.
Characteristics:
1.Saturable dyeing can be done under regular pressure and 100ºC conditions, no need for high temperature or high pressure in order for dyeing to take place.
2.Brightly colored ,Excellent color fastness(>4.5grade)
3.Interweaving with spandex yarn or nylon could increased color fastness
4.When the fabrics coating or laminating with CD ,could improve dyestuff migration
5.Conjugating with regular polyester, different color effect can be created.
