Problems solved by technology

[0004] However, when the above-mentioned knitted fabrics are used for high-risk task groups such as firefighters and special armed police, due to the low ignition point of this fiber, when firefighters and armed police personnel are at the scene of a fire to rescue the people, this fabric is easily ignited by the flames on the scene. Burning, causing injury to firefighters and armed police personnel

preparation example Construction

[0038] A method for preparing a bulletproof, cutproof and flame retardant fabric, comprising the steps of:

[0039] Step 1: manufacture gray cloth, gray cloth comprises base yarn and veil, as attached figure 1 and figure 2 As shown, the bottom yarn is manufactured by the multi-axis warp knitting method, and the bottom yarn includes aramid fiber yarn 1, carbon fiber yarn 3 and steel-clad wire yarn 2; the aramid fiber yarn 1 in the bottom yarn can choose aramid 1313 In any one of the three filaments, aramid 1414 filaments or mixed fibers of aramid 1313 and aramid 1414, a plurality of aramid fiber yarns 1 are arranged and distributed in parallel to form the first tensile stress layer.

[0040] Steel-clad yarn 2 is made of stainless steel wire as the base, and then covered with aramid 1414 yarn. There are two groups of steel-clad yarn 2, which are laid on the first tensile layer in two layers. A plurality of steel-clad yarns 2 are arranged in parallel to form a tear-resistant f...

Embodiment 1

[0069] Embodiment 1: Aramid fiber yarn 1 in the bottom yarn is made by blending aramid 1313 staple fiber and aramid 1414 staple fiber, wherein the weight ratio of aramid 1313 staple fiber is 30%, and aramid 1414 staple fiber The weight ratio is 70%.

Embodiment 2

[0070] Embodiment 2: Aramid fiber yarn 1 in the bottom yarn is made by blending aramid 1313 staple fiber and aramid 1414 staple fiber; wherein, the weight ratio of aramid 1313 staple fiber is 40%, and aramid 1414 staple fiber The weight ratio is 60%.

Abstract

The invention relates to the field of fabric preparation, and discloses a method for preparing a bulletproof, cutting-resistant and inflaming-resistant fabric. The method comprises the following stepsthat Step 1, gray fabric is prepared, wherein the gray fabric comprises ground yarn and shell yarn, the ground yarn comprises aramid fiber yarn, the shell yarn comprises inflaming-resistant fiber yarn, and the ground yarn and the shell yarn are sewn to be combined to form the gray fabric; Step 2, gray fabric raising is carried out, wherein the surface of the shell fabric fluffs through a raisingmachine, and fluff on the surface of the shell yarn is combed, so that the gray fabric becomes raised cloth; Step 3, the gray fabric is shaped, wherein the raised cloth forms a finished fabric througha shaping machine. The tensile performance and tear resisting performance of the gray fabric can be enhanced through the characteristic of the aramid fiber yarn, the inflaming resistance of the grayfabric can be improved through the inflaming-resistant fiber yarn, and therefore the fabric cannot be ignited by open fire easily. The air chamber effect on the surface of the gray fabric can be enhanced through the fluff, the human body and external air are separated, the temperature of a fire scene cannot be transferred to a wearer easily, and therefore the aim of protecting the human body to acertain degree is achieved.

Description

technical field [0001] The invention relates to a preparation method of a bulletproof, cutproof and flame retardant fabric. Background technique [0002] The production technology of knitted fabric is known, and generally comprises the following steps: steps such as spinning, weaving, dyeing, finishing and setting. With the improvement of people's material living standards, the requirements for clothing fabrics have also increased accordingly. In order to meet the needs of consumers, cater to the fiercely competitive market, and seek a place for development, all fabric manufacturers have set their sights on the development of fabrics with certain functions. Therefore, a variety of new functional fabrics have been widely used in recent years, such as nano-antibacterial fabrics, waterproof and moisture-permeable fabrics, bamboo charcoal fiber fabrics with far-infrared and anion-emitting functions, and heat-retaining fabrics. [0003] At present, the Chinese patent with the no...
