Embodiment 1

[0017] Such as figure 1 As shown, a cut-resistant yarn described in this embodiment is composed of ultra-high molecular weight polyethylene fiber 2, polyester low elastic yarn 3, and glass fiber 1. After glass fiber 1 and ultra-high molecular weight polyethylene fiber 2 are paralleled, Two polyester low elastic yarns 3 are cross-wrapped on the outside to form a core-spun yarn; glass fiber 1 and ultra-high molecular weight polyethylene fiber 2 are cross-wrapped by two polyester low elastic yarns 3, wherein the polyester yarn located on the outside The twist of the low elastic yarn 3 is 350 twists / meter when covering, and the twist of the polyester low elastic yarn 3 inside is 400 twists / meter when covering. The mass ratio of the ultra-high molecular weight polyethylene fiber 2, the polyester low elastic yarn 3, and the glass fiber 1 is: 68:21:11. Such a coating form can achieve a more comprehensive and uniform coating on the glass fiber 1 through reasonable control of the twis...

Embodiment 2

[0019] Such as figure 2 As shown, a cut-resistant yarn described in this embodiment is composed of ultra-high molecular weight polyethylene fiber 2, polyester low elastic yarn 3, and glass fiber 1. Two polyester low elastic yarns 3 are crossed outside the glass fiber 1. Covering, wherein the twist of the polyester low elastic yarn 3 positioned on the outside is 800 twists / meter when covered, and the twist of the polyester low elastic yarn 3 positioned on the inside is 900 twists / meter when covered. Then the glass fiber 1 coated with polyester low elastic yarn 3 is cross-wrapped with two ultra-high molecular weight polyethylene fibers 2 or one ultra-high molecular weight polyethylene fiber 2 and one polyester low elastic yarn 3 to form a core Yarn; In this form, when the polyester low elastic yarn 3 and the ultra-high molecular weight polyethylene fiber 2 are coated with the glass fiber 1 coated with the polyester low elastic yarn 3, the polyester low elastic yarn 3 and the ul...

Embodiment 3

[0021] Such as image 3 As shown, a cut-resistant yarn described in this embodiment is composed of ultra-high molecular weight polyethylene fiber 2, polyester low-elastic yarn 3, and glass fiber 1. A polyester low-elastic yarn 3 and glass fiber 1 are passed outside the glass fiber 1. An ultra-high molecular weight polyethylene fiber 2 is cross-wrapped, and the ultra-high molecular weight polyethylene fiber 2 is located between the polyester low elastic yarn 3 and the glass fiber 1 to form a core-spun yarn. In the third wrapping form, the twist of the ultra-high molecular weight polyethylene fiber 2 when wrapping is 400 twists / meter, the twist of the polyester low-stretch yarn 3 is 300 twists / meter when wrapping, and the polyester low-stretch yarn The twist of 3 is smaller than that of UHMWPE fiber 2. In this form of covering process, the glass fiber 1 is exposed to 20-40%, which also has strong cutting resistance.

Abstract

The invention relates to the technical field of yarn, in particular to cutting-resistant yarn. The cutting-resistant yarn is prepared from ultra-high molecular weight polyethylene fibers, polyester drawn textured yarn and glass fibers. The cutting-resistant and stab-resistant fabric is formed by knitting or tatting the cutting-resistant yarn. The obtained cutting-resistant yarn and cutting-resistant and stab-resistant fabric have strong cutting resistance and stab resistance, the cutting resistance can reach level 5 of American Standard and level 5 of European standard EN388:2016, the stab resistance of the cutting-resistant and stab-resistant fabric can reach level 4, and the cutting resistance and the stab resistance can both reach the highest level.

Description

technical field [0001] The invention relates to the technical field of yarns, in particular to a cut-resistant yarn and a cut-resistant and stab-resistant fabric. Background technique [0002] In the prior art, glass fibers and ultra-high molecular weight polyethylene fibers are used to weave cut-resistant and stab-resistant fabrics, such as Chinese patent, patent number 201510257903.2, and the patent name is the preparation of ultra-high molecular weight polyethylene fiber cotton type cut-resistant gloves The method discloses that the blended yarn of ultra-high molecular weight polyethylene fiber and polyester broken string, polyester-coated spandex covered yarn, and PVC-coated glass fiber spandex filament yarn are used for weaving to form cut-resistant gloves. Although it has a certain cutting resistance, its stab resistance is poor due to the characteristics of the weaving, and the cut resistance and stab resistance of the whole glove are average.
