Anti-cutting rubber-coated yarn

Abstract

An anti-cutting rubber-coated yarn includes a yarn body and a mixed rubber layer coated on the yarn body. A plurality of tiny pits is distributed on a surface of the yarn body, and the mixed rubber layer is attached in the tiny pits and is coated on an outside of the yarn body. According to the present invention, numerous tiny pits are made by etching on the surface of the existing yarn body, and simultaneously, molecular bonds on the surface of the yarn body are broken. In a dipping process, molecular bonding occurs between the rubber and the yarn body while the tiny pits are filled with the rubber and the tiny hard particles, thereby further enhancing adsorption fastness of the mixed rubber layer.

Claims

1. An anti-cutting rubber-coated yarn, comprising a yarn body and a mixed rubber layer coated on the yarn body, wherein a plurality of tiny pits are distributed on a surface of the yarn body, and the mixed rubber layer is attached in the tiny pits and is coated on an outside of the yarn body, wherein the yarn body is a polyethylene (PE)-coated yarn coated with spandex and nylon.

2. The anti-cutting rubber-coated yarn according to claim 1, wherein the mixed rubber layer covers the PE-coated yarn coated with spandex and nylon is formed by mixing one of butadiene-acrylonitrile rubber, latex, neoprene rubber, and silica gel, or a mixture thereof in any ratio and a tiny hard particle.

3. The anti-cutting rubber-coated yarn according to claim 1, wherein the PE-coated yarn is high-strength polyethylene fiber-coated yarn coated with spandex and nylon.

4. The anti-cutting rubber-coated yarn according to claim 2, wherein a pigment substance is added to the mixed rubber layer as needed.

5. The anti-cutting rubber-coated yarn according to claim 2, wherein a flame retardant substance, a moisture sweat-absorbing substance, a heating substance, or a refrigerating substance is added to the mixed rubber layer as needed.

6. The anti-cutting rubber-coated yarn according to claim 2, wherein the tiny hard particle is one of a metal particle and a stone particle, or a mixture thereof.

7. The anti-cutting rubber-coated yarn according to claim 2, wherein the tiny hard particle is one of SiO.sub.2 and glass fiber powder, or a mixture thereof in any ratio.

DETAILED DESCRIPTION OF THE INVENTION

(4) As shown in FIG. 1 to FIG. 3, an anti-cutting rubber-coated yarn comprises a yarn body and a mixed rubber layer coated on the yarn body. The mixed rubber layer is formed by mixing one of butadiene-acrylonitrile rubber, latex, neoprene rubber, and silica gel, or a mixture thereof in any ratio and tiny hard particles. The tiny hard particle is one of a metal particle and a stone particle, or a mixture thereof. The yarn body is a PE yarn, a PE-coated yarn coated with spandex, a PE-coated yarn coated with nylon, or a PE-coated yarn coated with spandex and nylon.

(5) Numerous irregularly distributed tiny pits are made by etching on a surface of the yarn body, and also, and at the same time, molecular bonds on the surface of the PE yarn are broken, and the mixed rubber layer is attached in the pits and coated on an outside of the yarn body. Since during the rubber coating process, the molecular bonding occurs between the rubber and the PE in the mixed rubber layer, the adsorption force between the mixed rubber layer and the yarn body is further enhanced, and simultaneously the anti-cutting level of the yarn is improved without affecting the weaving property of the yarn, such that the anti-cutting level of protective gloves woven from the anti-cutting coated yarn can reach Level 5 of the American Standard. Moreover, the gloves are lightweight and flexible, and protect an operator's hands from the threat of cutting and puncture from work.

(6) It is noted herein that the tiny hard particle is one of SiO.sub.2 and glass fiber powder, or a mixture thereof in any ratio.

(7) Preferably, the yarn body is a high-strength polyethylene fiber, a high-strength polyethylene fiber-coated yarn coated with spandex, a high-strength polyethylene fiber-coated yarn coated with nylon, or a high-strength polyethylene fiber-coated yarn coated with spandex and nylon.

(8) A pigment substance is added to the mixed rubber layer as needed.

(9) A flame retardant substance, a moisture sweat-absorbing substance, a heating substance, or a refrigerating substance, such as carbon black and a self-heating composite material, and so on, is added to the mixed rubber layer as needed.

(10) On the basis of the foregoing technical solution, the material of the yarn body may further be HPPE, nylon, dacron, Kevlar, aramid, bamboo fiber, acrylic fiber, or tencel.
