Description
Technical field
The invention belongs to anti-perforation fabric technical fields, and in particular to a kind of preparation method of anti-stab coating kevlar fabric.
Background technique
With the rapid development of society, some international terrorist incidents happen occasionally, this event promotes individual protection
The development of technology.It is some with cutter phase although many countries including China have carried out cutter stringent control
The incident of violence of pass happens occasionally, so the research and development of Anti-prick clothes are widely paid close attention to.Anti-prick clothes require both to have met anti-stab
It is required that and can take.Raising with people to the anti-stab performance requirement of clothes, there is an urgent need to good concealment, comfort level height and valences
The cheap stab-resistance body armor of lattice.In terms of the material of Anti-prick clothes, aramid fiber is obtained extensively with its unique advantage in stab-resistant material
Application, aramid fiber is a kind of novel synthetic fibers, and its chemical name is phenyl-diformyl phenylenediamines.But simple aramid fiber is fine
The anti-stab performance of dimension is also unsatisfactory, needs to be further increased.
The anti-stab mechanism of fabric is cut for the shearing thorn that bayonet is low speed low energy, i.e., energy drops rapidly when bayonet is pierced into clothes
Low, the fiber from being pierced into region propagates impact energy to the region other than contact point.Currently, the anti-stab research of fabric also has
The anti-stab function of fabric is mainly unfolded from the following aspects: (1) setting during yarn is woven into fabric for more report
Count different thread layer and weft layers, such as: Chinese Patent Application No. 201620244156.9 disclose a kind of anti-perforation fabric and its
Weaving device, the patent is using host for being interleaved warp thread, weft yarn and bundled yarn, and warp beam is for winding warp thread or binding
Yarn, and warp thread or bundled yarn are transmitted to host.(2) substance of some anti-stab functions is wrapped up in fabric interlayer, such as: China is specially
Sharp application number 200610064171.6 discloses anti-perforation fabric, and the patent is by multi-layered polyester and/or polyamide fabric layer phase each other
It is mutually fixed, and the sandwich being collectively formed with middle layer made of latex, EVA or polyurethane, made respectively by heat and pressure
Part connects.(3) protection module is embedded between fabric, such as: Chinese Patent Application No. 201710323336.5 discloses a kind of soft
Property anti-perforation fabric, multiple compact arranged protection modules in five gaps are equipped on flexible substrate, adjacent protection module passes through phase
The diplopore clamp ring mutually cooperated and connection buckle are connected and fixed.These methods can play certain anti-stab specific fabric
Effect, still, these methods come with some shortcomings for the anti-stab performance enhancement of aramid fiber, because of aramid fiber self-strength
Height inherently has certain anti-stab performance.Therefore, the anti-stab performance that further increase aramid fiber, needs to seek new
Technology.
