Problems solved by technology

[0005] The technical problem mainly solved by the present invention is that the existing stab-proof clothing materials have insufficient toughness and poor burst resistance, and at the same time, because the resin material has air-tightness and moisture-tightness, the composite material will cause sweat to be impervious when people wear it. Emission, the body surface temperature rises, and the wearer will have obvious discomfort defects, and a preparation method for a stab-resistant composite material is provided

example 1

[0021] According to the mass ratio of 1:1, the ramie fiber and sisal fiber are mixed to obtain a mixed fiber. According to the mass ratio of 1:10, the mixed fiber and deionized water are stirred and mixed, and the pH is adjusted to 8.0 with a mass fraction of 10% sodium hydroxide solution , Get the mixed solution, and then add xylanase to the mixed solution at 55~60℃ according to the enzyme addition amount 15U / g. After stirring and mixing for 3~5h, the enzyme hydrolysis solution is obtained. The volume ratio is 1: 5. Add 25% solid content silica sol to the enzymolysis solution, stir and mix for 6-8h at 3500~4000r / min, then stop stirring and filter, collect the filter cake and freeze-dry in vacuum, collect the dried modified fiber and put it together Twist the yarn in the fancy twisting machine, collect the mixed fiber thread, place it on the loom for weaving, control the weft density to 150 strands / 10cm, and the warp density to 250 strands / 10cm. After weaving is completed, colle...

Abstract

The invention belongs to the technical field of textile materials and in particular relates to a preparation method of a puncture-proof composite material. According to the preparation method, abutilon fibers and sisal fibers are mixed; after being subjected to enzymolysis treatment, the abutilon fibers and the sisal fibers are compounded with silica sol; after the enzymolysis treatment is carried out on surfaces of the fibers, cell walls on the surfaces of the fibers are damaged by xylanase and hemicellulose in the mixed fibers is degraded, so that the cell walls of the fibers become loose; then nano silicon dioxide particles are used for effectively filling the cell walls of the fibers under a high-speed stirring condition to modify the bursting-resisting performance and toughness of a fiber material, so that the anti-impact performance of the puncture-proof composite material is effectively improved; the mixed fibers are effectively compounded with thermosetting resin and a molecular chain in the mixed fibers contains a large quantity of hydroxyl and is used for adsorbing water molecules; sweat of a human body can be absorbed under the condition that the human body perspires and the sweat is not accumulated on the body surface, so that the human body perspires effectively and breathable holes is formed, and the air permeability of the material is improved.

Description

Technical field [0001] The invention belongs to the technical field of fabric materials, and specifically relates to a preparation method of a stab-resistant composite material. Background technique [0002] With the rapid advancement of high molecular weight aggregate material science and technology, especially since the company successfully developed para-aramid, abbreviated as aramid fiber, everyone has gradually overcome the mindset of rigidity; many differences Synthetic organic fibers with excellent types and performance have come out one after another, and the comprehensive application of biotechnology and nanotechnology has brought unprecedented revolutionary breakthroughs to the development of human stab-resistant armor, and has promoted it to excellent stab-resistant performance, A further leap has been made in the direction of light weight and wearing comfort. Among the stab-resistant fabrics that have been developed, metal materials such as stainless steel, titanium,...
