Embodiment 1

[0046] This flexible stab-resistant fabric uses nylon plain fabric as the base fabric, and the surface density is 180g / m 2 , the warp and weft density is 308×316 (root / 10cm). E44 epoxy resin and 650 polyamide resin curing agent, the mass ratio is 1:0.9, add 8% dioctyl phthalate toughening agent, 5% epoxy diluent (SM-90) and 5% resin mass % of color particles. The manufacturing process of this anti-stab fabric is as follows: a, at first epoxy resin is mixed with curing agent and auxiliary agent; b, this example adopts Figure 6 Honeycomb pattern screen, the side length of the hexagonal mesh in the screen is 4mm, the gap between the mesh and the mesh is 1mm, the height of the mesh is 1.0mm, and the resin mixture is evenly dispersed on each of the screen In the mesh, fill each mesh with resin, and then use a scraper to scrape off the excess resin on the surface of the mesh; c, spread the nylon fabric on the mesh filled with resin, and apply a surface of the same size and surfac...

Embodiment 2

[0050] This flexible anti-stab fabric uses polyester plain weave fabric as the base fabric, with a surface density of 210g / m 2 , the warp and weft density is 160×166 (root / 10cm). E44 epoxy resin and 650 polyamide resin curing agent, the mass ratio is 1:1, add 10% of resin mass dioctyl phthalate toughener, 5% epoxy diluent (SM-90) and 5 % of color particles. The manufacturing process of this anti-stab fabric is as follows: a, at first epoxy resin is mixed with curing agent and auxiliary agent; b, this example adopts Figure 5 The pentagons of the same size surround the square pattern of the screen, the side length of the pentagon mesh in the screen is 3mm, the side length of the square mesh is 5mm, the gap between the mesh and the mesh is 0.8mm, and the height of the mesh is 0.9 mm, the resin mixture is evenly dispersed in each mesh of the screen, so that each mesh is filled with resin, and then use a scraper to scrape off the excess resin on the surface of the screen; c, spr...

Embodiment 3

[0054] This flexible anti-stab fabric uses polyester plain weave fabric as the base fabric, with a surface density of 245g / m 2 , the warp and weft density is 280×298 (root / 10cm). Thermosetting acrylic resin (BS-965), isocyanate curing agent (740D), the mass ratio is 3:1, and 10% of the resin mass is added as a toughening agent of dibutyl benzene. The manufacturing process of this anti-stab fabric is as follows: a, at first this thermosetting acrylic resin is mixed with curing agent, auxiliary agent; B, this example adopts image 3 A mesh plate with the same size squares arranged in dislocation patterns, the side length of the square mesh in the mesh plate is 3mm, the gap between the mesh holes is 0.8mm, and the mesh height is 1.1mm. The resin mixture is evenly dispersed in the In each mesh hole of the screen, fill each mesh with resin, and then use a scraper to scrape off the excess resin on the surface of the screen; c, spread the polyester fabric on the screen filled with r...

Abstract

The invention relates to a resin-formed flexible puncture-proof fabric and a preparation method of the resin-formed flexible puncture-proof fabric. The fabric consists of garment fabric and thermosetting resin condensates, wherein a gap exists between the thermosetting resin condensates. The preparation method comprises the following steps of: uniformly dispersing the thermosetting resin in each mesh of a screen plate so that each mesh is filled with resin; scraping residual resin on the surface of the screen plate; spreading the garment fabric on the screen plate filled with resin; applying pressure to the garment fabric, and drying; solidifying the thermosetting resin condensate on the surface of the garment fabric; and finally removing the thermosetting resin condensate from the screen plate to obtain the resin-formed flexible puncture-proof fabric. According to the invention, the thermosetting resin is a good binder before solidification, has a good binding effect with the garment fabric and relatively high strength and hardness after solidification, and can resist the puncture of a conventional tool needle tube; and the shortcomings and defects of the prior art are overcome, and the needs of the military field and civil field are met.

Description

technical field [0001] The invention belongs to the field of protective fabric and its preparation, in particular to a resin-formed flexible stab-resistant fabric and a preparation method thereof. Background technique [0002] Even in peaceful times, violent conflicts continue to occur in countries all over the world. In order to ensure that the main organs of the public security officers are not or less injured by common sharp objects such as daggers when performing tasks, it is necessary for the majority of public security officers and security personnel to be equipped with protective equipment, and stab-proof clothing is one of the important protective equipment. And along with the raising of people's requirements for clothing protective performance, there is an urgent need for novel stab-resistant fabrics with good concealment performance, comfort, breathability, flexibility, lightness, and low price. In addition, stab-resistant fabrics can also be used to make stab-re...
