Problems solved by technology

However, during the napping process of the above-mentioned light, warm, and flame-retardant fleece fabrics, the napping machine will break the loop yarn and pull out the aramid fiber to form fluff, which destroys the strength and modulus of the aramid fiber yarn. , resulting in this kind of light, warm, flame-retardant velvet fabric does not have the effect of bulletproof, cut-proof and flame-retardant

Embodiment 1

[0044] Example 1: A method for preparing a bullet-proof, cut-proof and flame-retardant fabric, including the following steps:

[0045] (1) A circular knitting machine is used to weave the fabric. Both the ground yarn and the face yarn contain aramid fiber filaments. The aramid fiber filaments are filaments made of aramid 1414 fibers, that is, aramid 1414 fiber filaments. Many loop yarns are polyester fiber yarns.

[0046] Before circular knitting, the aramid fiber yarn is irradiated with gamma rays to cause the cross-linking reaction between the skin layer and the core layer of the aramid fiber to increase the tensile strength of the aramid fiber yarn. The tensile strength comparison table of aramid fiber yarn is shown in Table 1:

[0047] Table 1: Comparison of tensile strength of aramid fiber yarn before and after γ-ray radiation

[0048]

[0049] According to Table 1, the tensile strength is the critical value for the transition of the measured object from uniform plastic deformat...

Embodiment 2

[0068] Example 2: A method for preparing a bulletproof, cut-resistant and flame-retardant fabric. The difference between this example and Example 1 is that the aramid fiber filaments in step (1) are aramid blended fibers, and the aramid blended fibers include The components in parts by weight are as follows: 10 parts of aramid 1313 fiber and 90 parts of aramid 1414 fiber.

Embodiment 3

[0069] Embodiment 3: A method for preparing a bulletproof, cut-proof and flame-retardant fabric. The difference between this embodiment and Embodiment 1 is that the aramid fiber filaments in step (1) are aramid blended fibers, and the aramid blended fibers include The components in parts by weight are as follows: 20 parts of aramid 1313 fiber and 80 parts of aramid 1414 fiber.

Abstract

The invention relates to the field of fabrics, and discloses a preparation method of a bulletproof, anti-cutting and anti-flaming fabric. The method comprises the following steps of 1, adopting a circular machine for knitting a fabric, wherein multiple pieces of ground yarn include aramid fiber filaments, multiple pieces of loop yarn include polyester fiber yarn; in the knitted fabric, after the ground yarn is knitted, a plurality of first coils arranged and distributed in the length direction are formed, after the loop yarn is knitted, a plurality of second coils arranged and distributed in the length direction are formed, looped piles opposite to the second coils are arranged and distributed in the length direction, the looped piles are perpendicular to the first coils, after the loopedyarn is knitted, the formed second coils and the first coils formed by knitting the ground yarn coincide, and meanwhile, in the follow steps, the coinciding first coils and second coils run through the first coils and the second coils which coincide in the previous step. When the circular machine is used for knitting, the adopted ground yarn contains aramid fiber filaments, the aramid fiber filaments have the advantages of being high in strength and modulus and capable of resisting flaming, and therefore the fabric has the effects of resisting bullets, preventing cutting and resisting flaming.

Description

Technical field [0001] The invention relates to the field of fabrics, in particular to a method for preparing bullet-proof, cut-proof and flame-retardant fabrics. Background technique [0002] Fabric is the material used to make clothing. Fabrics can not only interpret the style and characteristics of clothing, but also directly influence the color and shape of clothing. The development trend of functional fabrics has received increasing attention. For example, in places where there are flammable substances such as petroleum and chemical industries, antistatic clothing made of antistatic fabrics are needed, and bulletproof clothing made of bulletproof fabrics are needed in the field of personal protection. [0003] Aramid 1313 is a meta-aramid fiber with a zigzag molecular chain. Aramid 1414 is a para-aramid fiber with a linear molecular chain. Aramid 1313 and aramid 1414 have ultra-high strength and high modulus. And high temperature resistance, acid and alkali resistance, light...
