Embodiment 1

[0060] The fabric was woven into a plain weave using peraramid multifilaments comprising peraramid monofilaments having a fineness of 1.0 as warp and weft. Warp density and weft density are 10pcs / cm. Next, at about 60 °C with Na 2 CO 3 The fabric is treated with a scouring agent, then washed with water and dried.

[0061] Next, the scoured fabric is dipped in a water repellant, which saturates the fabric. The water repellent comprises 3% by weight of hydroxylated perfluoroalkyl ethyl acrylate copolymer, 3% by weight of polyethylene terephthalate, 3% by weight of toluene diisocyanate, 0.3% by weight of dipropylene glycol , 0.3% by weight of maleic acid, 0.3% by weight of maleic acid and 90.1% by weight of water.

[0062] The fabric impregnated with the water repellent was heat-treated at a temperature of about 160° C. for 60 seconds to obtain a bulletproof fabric.

Embodiment 2

[0064] A bulletproof fabric was prepared in the same manner as described in Example 1, except that a water repellent containing the same content of polyacrylate resin was used instead of polyethylene terephthalate.

Embodiment 3

[0066] A bulletproof fabric was prepared in the same manner as described in Example 1, except that a water repellent containing the same content of melamine resin was used instead of polyethylene terephthalate.

Abstract

Disclosed are a bulletproof fabric and a method for producing the same that exhibit improved anti-traumaproperty and minimize deterioration in bulletproofness even after use under harsh conditions for a long period of time. The bulletproof fabric includes a fabric comprising at least one high-strength fiber selected from the group consisting of a high molecular weight polyethylene fiber, an aramid fiber, and a polybenzoxazole fiber, and a water repellent layer disposed on the high-strength fiber, wherein the water repellent layer is formed by treating the fabric with a water-repellent agent comprising fluorocarbon and a hardness-enhancing resin, and the hardness-enhancing resin is a polyvinyl acetate resin, a polyester resin, a polyacrylate resin, a melamine resin, or a mixture of two or more thereof.

Description

technical field [0001] The present invention relates to bulletproof fabric and its preparation method. More particularly, the present invention relates to a ballistic-resistant fabric exhibiting improved damage resistance and minimizing deterioration of ballistic-resistant performance even after prolonged use under severe environments, and a method for producing the same. Background technique [0002] Body armor is a type of clothing developed to protect the human body from shell fragments or bullets. Therefore, the most important requirement for body armor is ballistic performance. However, since the high-strength fibers constituting the body armor are easily damaged by water, serious problems have arisen, such as deterioration of the ballistic performance of the body armor under harsh environments or after long-term use. [0003] In order to solve the above problems, the present applicant has proposed a water repellent treatment method using bulletproof fabric (Korean Pa...
