摘要:
Provided are a nanofiber composite unidirectional fabric and a preparation method therefor. The nanofiber composite unidirectional fabric according to the present invention comprises at least two unidirectional sheet layers and nanofibers located between adjacent unidirectional sheet layers. The unidirectional sheet layers each comprise unidirectionally arranged high-performance fibers and an adhesive, and the adhesive comprises nanofibers. The provided nanofiber composite unidirectional fabric has a novel composite structure, which integrates the comprehensive characteristics of fiber filaments, a resin matrix and nanofibers. The nanofiber composite unidirectional fabric of the present invention has excellent bulletproof performance and is suitable for novel bulletproof sheets.

The present invention provides a polyethylene fiber which can attain a high dye exhaustion rate, which indicates deep color, and which is excellent in dyeability and color fastness; a woven or knit textile that uses the polyethylene fiber, and that is excellent in cut-resistance and heat-retaining property, and a glove thereof. A polyethylene fiber of the present invention is characterized by having an intrinsic viscosity [·] of 0.8 dL/g or more and less than 5 dL/g; being composed of a repeating unit substantially derived from ethylene; having pores being formed from a surface of the fiber to an inside of the fiber; having an average diameter of the pores of ranging from 3 nm to 1 µm when the diameter is measured, by each pore being approximated by a column, at a contact angle of 140 degrees, in a mercury intrusion method; a porosity of the pores of ranging from 1.5% to 20%1; or a thermal conductivity in a fiber axis direction at a temperature of 300 K of ranging from 6 W/mK to 50 W/mK.

The present invention provides a high strength fiber coated with a coating composition, wherein the coating composition contains a UV absorber. The UV absorber can be selected from the group consisting of hydroxybenzophenones, hydroxyphenylbenzotriazoles, oxalanilides, phenyl esters, benzooxazinones, cyanoacrylates, formamidine, benzylidene malonates and hydroxyphenyl triazines and combinations thereof. Such fibers are particularly useful in ropes and fishing nets.
