Problems solved by technology

The existing technology mainly prevents see-through through coating finishing technology. For clothing textiles, coating finishing affects its wearing comfort, such as the impact on air permeability, etc.
At the same time, the adjustment of post-finishing and fabric texture has a limited degree of adjustment to the visual properties of the fabric, and the durability is insufficient.

Abstract

The invention relates to an anti-perspective DTY fiber and a preparation method thereof. The anti-perspective DTY fiber is a non-stripping orange segment-shaped two-component composite fiber. Non-stripping means that the two components have good compatibility; the two components are high polymer and the high polymer containing 5-16wt% TiO2, wherein the high polymer containing 5-16wt% TiO2 accounts for 6-30wt% of the anti-perspective DTY fiber; the anti-perspective DTY fiber is a round fiber containing 5-16wt The high polymer of %TiO2 is fan-shaped distribution starting from the center of the circle, and the radius of the fan is 4 / 5-11 / 12 of the radius of the anti-perspective DTY fiber; the opacity of the anti-perspective DTY fiber reaches 99%-100%. The anti-see-through DTY fiber of the present invention has high opacity, and its physical properties are almost the same as those of conventional fibers; the woven fabric has obvious shading effect, greatly reduces the transmission of visible light, and makes the transmission of visible light almost zero.

Description

technical field [0001] The invention belongs to the technical field, and relates to an anti-perspective DTY fiber and a preparation method thereof. Background technique [0002] The development of functional fibers, differential fibers and high-performance fibers has created favorable conditions for the technological innovation of the traditional textile industry and the transformation to high-tech industries, and has contributed to the improvement of human living standards. Functional fiber refers to a new type of fiber that has some special function in addition to the physical and mechanical properties of ordinary fibers. It is a fiber that meets certain special requirements and uses, that is, the fiber has certain physical and chemical properties. The output of conventional chemical fibers can basically meet the needs of the society, but there are still many deficiencies in performance, which cannot meet the needs of consumers. For example, some functions of fibers need ...
