Moisture-absorption and Quickdrying Anti-ultraviolet Polyester Fiber

2025-03-20News 980

Reasons for recommendation

The fiber, featuring anti-ultraviolet, heat shielding, moisture-absorption and quick-drying capabilities, keeps skin protected from intense sun and maintains a dry and comfortable feeling. lt is the perfect companion for summer clothing fabrics.

Preparative technique

A certain proportion of anti-ultraviolet functional master batches are blended with polyester pellets, and then processed through a deformed spinneret plate to produce the fiber through the melt spinning technique.

Features of fibers and finished products

Filament: 50dtex/48fDTY

Polyester draw textured yarn(GB/T 14460-2015)

Properties of fibers and features of finished products

.Cruciform section design, which allows sweat to be quickly transported to the fabric surface and evaporated in the process of wicking, transporting, and diffusing, and achieves the effect of moisture-absorption and quick-drying.

.Anti-ultraviolet performance UPF50+,T(UVA) 4.44%.

Q: What are the main principles and influencing factors of the anti-

ultraviolet function in fibers and fabrics?

A: Anti-ultraviolet fiber is a type of fiber material that can effectively prevent the penetration of ultraviolet rays. Its principle involves the addition of additives that have the function of reflecting and scattering ultraviolet rays, effectively blocking ultraviolet rays from reaching human skin and serving as a sunscreen.The section shape of the fiber and the structure of the fabric will affect their anti-ultraviolet performance. Fibers with smoother surfaces and larger surface areas tend to have better anti-ultraviolet performance. Fabrics with low porosity and

that are thick and dense have better anti-ultraviolet performance.
