Embodiment 1

[0046] Cut and puncture resistance of industrial protective gloves

[0047] The present invention measures cut performance according to the ANSI / ISEA 105 cut protection standard and measures puncture resistance according to the ASTM F2878 standard. In one embodiment, the weight ratio of water-based polyurethane and silica sol in the mixed adhesive layer of water-based polyurethane and silica sol is 1-3:3-1, different weight ratios can prepare gloves with different cutting resistance and puncture resistance , and the test results are shown in Table 1.

[0048] Table 1 - Effect of weight ratio of waterborne polyurethane to silica sol on cut resistance and puncture resistance

[0049]

[0050]It can be seen from the results in Table 1 that when the coated fabric only uses the polyurethane layer, the industrial protective gloves have a cut resistance of 7N to 8N according to ANSI / ISEA105, and when the coated fabric only uses the silica sol layer, the industrial protective gl...

Embodiment 2

[0055] Puncture Resistance of Gloves Coated Fabrics with Different Coating Numbers

[0056] The industrial protective gloves of the present invention can be made of at least one layer of cut-resistant and puncture-resistant coated fabric. Preferably, the industrial protective gloves of the present invention may comprise one-layer, two-layer or three-layer coated fabrics, and the results of the puncture resistance test are shown in the table below.

[0057] Table 2 - Puncture resistance of one- and three-layer coated fabrics

[0058]

[0059] It can be seen from the results in Table 2 that when the industrial protective glove comprises a layer of coated fabric, the industrial protective glove has a puncture resistance of 3N to 4N according to ASTM F2878, and the puncture resistance grade is grade 1. When the industrial protective glove comprises a three-layer coated fabric, the industrial protective glove has a puncture resistance of 11 N according to ASTM F2878 with a pu...

Embodiment 3

[0061] figure 1 Different types of coated fabrics are shown and the areal densities of these coated fabrics are given in the table below. As can be seen from the results in Table 3, Samples 1 to 4 are layered fabrics of different colors, having a thickness of approximately 150 to 250 g / m 2 while samples 6 to 9 are coated fabrics of different types (flannel or leather) in black, white or gray, with approximately 150 to 350 g / m 2 area density.

[0063]

[0064] figure 2 Shown is the puncture resistance of different types of coated fabrics. Samples 1 to 4 are layered fabrics of different colors with a puncture resistance of 1N to 7N according to ASTM F2878, while samples 6 to 9 are coated fabrics of different types (velvet or leather) in black, white or gray according to ASTM F2878 F2878 has a puncture resistance of 2N to 10N.

Abstract

The invention relates to a cutting-resistant and puncture-resistant industrial protective glove, which comprises a glove body, the glove body is formed by connecting a finger part and a palm part, and the glove body is made of at least one layer of cutting-resistant and puncture-resistant coated fabrics. The industrial protective gloves according to the invention have a cut resistance of at least 7N according to ANSI / ISEA 105 and a puncture resistance of at least 3N according to ASTM F2878. When the glove body comprises a layer of cutting-resistant and puncture-resistant coated fabrics, the industrial protective glove has a puncture resistance of 3N to 4N according to ASTM F2878. When the glove body comprises three layers of cutting-resistant and puncture-resistant coated fabrics, the industrial protective glove has a puncture resistance of at least 11 N according to ASTM F2878.

Description

technical field [0001] The invention belongs to the technical field of weaving, and in particular relates to the preparation of a cut-resistant / puncture-resistant fabric for industrial protective gloves and a preparation method thereof. Background technique [0002] Protective gloves are one of the very important protective gear products for workers on the construction site, which can reduce the chance of workers' hands and fingers being injured during the construction process. [0003] Strong fiber composite materials such as high molecular weight polyethylene or poly-p-phenylene terephthalamide (UHMWPE / Kevlar) are currently widely used commercially to make cut-resistant gloves. [0004] Chinese Patent Publication Application No. 102326896 discloses a cut-resistant glove that uses Kevlar yarn and cotton yarn as raw materials. The gloves produced are not only soft to wear, flexible in fingers, durable, but also have a good sweat-absorbing effect in the inner core, and a good...
