AI Technical Summary

Benefits of technology

The present invention is a bulletproof garment that minimizes deformation caused by shock or impact, while still providing a comfortable fit. The garment is made using the bulletproof fabric, which helps prevent damage to the body from shell fragments or bullets. Additionally, the garment maintains its superior bulletproofness even after extended use in harsh environments.

Problems solved by technology

However, since high-strength fibers constituting the bulletproof garment are vulnerable to water, a serious problem such as deterioration in bulletproofness of bulletproof garments under harsh environments or after use for a long period of time occurs.
However, a problem in which water repellency imparted to the bulletproof fabric using water repellent treatment cannot be maintained for a long period of time still remains.
That is, the water-repellent agent component (for example, a fluorocarbon compound) that is adhered to the bulletproof fabric through water repellent treatment is disadvantageously readily removed from the bulletproof fabric due to exterior environments and / or passage of time.
As a result, a conventional bulletproof garment has a serious problem in that bulletproofness thereof is significantly deteriorated under harsh environments or after use for a long period of time.
When the bulletproof garment is excessively heavy or inflexible, it is not considered to be a good bulletproof garment due to deteriorated wear feeling although it exhibits superior bulletproofness.
In consideration of wear feeling, the bulletproof garment should be produced with a soft bulletproof fabric having a stiffness (flexibility) of 10 N to 70 N. However, a general soft bulletproof fabric has a limitation of unsatisfactory anti-trauma property.
Serious backface deformation of the bulletproof fabric may cause fatal damage to users.

Effect test

example 1

[0056]A fabric was woven as a plain weave using wholly aromatic polyamide multi-filaments comprising wholly aromatic polyamide monofilaments having a fineness of 1.0 as warps and wefts. The warp density and the weft density were 10 pcs / cm. Subsequently, the fabric was treated at about 60° C. with a scouring agent comprising Naz CO3, washed with water and dried.

[0057]Subsequently, the scoured fabric was immersed in a water-repellent agent to impregnate the water-repellent agent in the fabric. The water-repellent agent comprises 3% by weight of a hydroxylated perfluoroalkylethyl acrylate copolymer, 3% by weight of polyethylene terephthalate, 3% by weight of toluene diisocyanate, 0.3% by weight of diprophylene glycol, 0.3% by weight of maleic acid, 0.3% by weight of maleic acid, and 90.1% by weight of water.

[0058]The water-repellent agent-impregnated fabric was heat-treated at a temperature of about 160° C. for 60 seconds to complete a bulletproof fabric.

example 2

[0059]A bulletproof fabric was prepared in the same manner as in Example 1, except that a water-repellent agent comprising the same amount of a polyacrylate resin, instead of polyethylene terephthalate was used.

example 3

[0060]A bulletproof fabric was prepared in the same manner as in Example 1, except that a water-repellent agent comprising the same amount of a melamine resin, instead of polyethylene terephthalate was used.

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 a bulletproof fabric and a method for producing the same. More specifically, the present invention relates to a bulletproof fabric and a method for producing the same that exhibit improved anti-trauma property and minimize deterioration in bulletproofness even after use under harsh conditions for a long period of time.BACKGROUND ART[0002]A bulletproof garment is clothing that is developed to protect the body from fragments of shells or bullets. Accordingly, the most important requirement of bulletproof garments is bulletproofness. However, since high-strength fibers constituting the bulletproof garment are vulnerable to water, a serious problem such as deterioration in bulletproofness of bulletproof garments under harsh environments or after use for a long period of time occurs.[0003]In order to solve this problem, the applicant suggested a water repellent treatment method using a bulletproof fabric (Korean Patent Laid-open No. 1...
