Hydrophilic and anti-pilling modified polyester fiber

2024-09-03News 6130

Recommendation Reasons

To solve the problem of high energy consumption of polyester fiber dyeing at high temperature and high pressure, the normal temperature dyeing method is adopted to reduce waste water discharge, save energy and reduce emission. The modified design makes the fiber soft and skin-friendly. moisture-absorption and quick-drying, low static electricity, and anti-pilling, as well as upgrades the wearing comfort.

Processing Technology

The third and fourth monomer are used to modify the polyester macromolecular chain, reduce

the regularity of the macromolecular chain and the modulus of polyester while increasing the

hydrophilic groups. Then melt direct-spinning is performed to produce the hydrophilic and anti-

pilling modified polyester fiber.

Weaving: Suitable for all kinds of weaving, knitting, braiding processing; the weaving process is

the same as the ordinary dacron

Dyeing and finishing: The dyeing process can be performed at normal pressure; if there

are special requirements such as special deep black, the temperature can be raised to

105~115℃ for dyeing; high color saturation,and good fixation

Heat-setting: the heat-setting temperature of fabrics is 15~ 20℃ lower than that of

ordinary dacron.

Fiber Application:Clothing textiles,Leisure wear,sportswear,Home wear,Down jacket

Home textiles:Bedding,Curtain,Sofa fabric

Q: What kinds of comfortable experiences can hydrophilic and anti-pilling modified polyester fibers bring to consumers when used in clothing?

A: The fiber has high moisture regain, low static electricity, and low charge density on fabric surface. Wearing it closely can increase skin affinity, and reduce static electricity and itchy feeling caused by skin contact. The appropriate reduction of fiber modulus can reduce fabric pilling and fluffing,avoiding skin friction and discomfort caused by pilling.
