Full-dull fine denier porous flat velvet-like polyester fiber

Recommendation Reasons

TiO₂in-situ polymerization and deformed section design are combined

with melt direct spinning. lts fabric has a unique style, rich velvet feeling

and ultraviolet resistance, so it has a good application in cotton-like velvet

fabrics.

Processing Technology

ln-situ polymerization technology is used in large-scale melt direct spinning equipment, and

the full-dull polyester melt can be prepared by adding TiO2 suspension in the production line in

the oligomer stage of the polymerization reaction, and then the full-dull fine denier porous flat

velvet-like polyester fiber can be prepared by spinning with porous flat spinneret plates.

The downstream application guidance

Spinning: It can achieve pure elasticity increase, or mix with other fibers for elasticity increase.

Weaving: It can be made into Chenille yarn and Crocheting yarn, which is used for weaving home textile decorative fabrics; it can also be directly used in a warp knitting machine to make.

warm-keeping home textile clothing fabrics of milk cashmere.

Dyeing and finishing: It is recommended to use an active printing and dyeing process

Q: Do you understand the development and subsequent application of the full-dull fine denier porous flat velvet-like polyester fiber?

A: The full-dull fine denier porous flat velvet-like polyester fiber appeared in China in about 2018. At that time, the number of fiber spinneret holes was less and the output was low. The production process was mainly based on the matting masterbatch injection method. Upon several years of development,the current product production technology has achieved breakthroughs.. ln-situ polymerization and online addition methods have gradually replaced the

master batch injection method, and the dispersion of titanium dioxide is more uniform and has the advantages of high productivity and excellent quality..The content of titanium dioxide and the number of fiber holes have beenfurther improved, with the titanium dioxide content reaching about 2.15% and the number of fiber holes being 192, 228 and 288. The color of the fiber is softer and the hand feel is more delicate. Its back-end applications have also been further expanded. It is widely used in the fields of home textiles, clothing, and decoration, and the market prospects are broad.
