Abstract

The utility model relates to a covered yarn, in particular to an anti-cutting covered yarn, which belongs to the personal protective appliance. The anti-cutting covered yarn consists of a core yarn, a middle yarn and an outer yarn; wherein, the middle yarn covers the core yarn; the outside of the middle yarn is coated by the outer yarn; the core yarn adopts the urethane elastic fiber; and the middle yarn consists of three layers with glass fiber as the middle core yarn and two layers of polyester low-stretch yarns coated outside. The utility model can greatly improve the wear resistance, cutting resistance and tear resistance of the anti-cutting covered yarn. Simultaneously, the anti-cutting covered yarn feels conformable, and the unit price is greatly reduced.

Description

The anti-cutting wrap yarn

Technical field

The utility model is a kind of wrap yarn, particularly a kind of anti-cutting wrap yarn that is used in the personal protective equipment.

Background technology

The existing anti-cutting yarn of existing market mainly contains two kinds: a kind of is coating cotton thread based on aramid fiber, the another kind of anti-cutting coating cotton thread that coats composition based on fine stainless steel wire, in conjunction with low elastic polyester filament.First kind of wrap yarn supplementary material price is high, and the cutting resistance of finished product can be undesirable; Second kind is cheap, but the finished product Boardy Feeling of making, heavy.

Chinese patent CN2898068, announce a kind of moisture absorbing and sweat releasing spandex coating cotton thread, inner core is a spandex fibre, be coated with the moisture absorbing and sweat releasing yarn in this spandex fibre periphery, contain hygroscopic fibre in this moisture absorbing and sweat releasing yarn, the surface of this hygroscopic fibre vertically is provided with four grooves in order to perspire along it, and this groove is distributed in the both sides of hygroscopic fibre in twos symmetrically.Function is single relatively, can not be used for this yarn individual's protective articles, and the comfortableness of this yarn is not good yet.

Summary of the invention

The utility model mainly is to solve the deficiencies in the prior art, a kind of wrap yarn of suitable personal protective equipment is provided, have anti-cutting, tear-resistant, anti abrasive performance, can satisfy the comfortableness that the individual uses, the unit price of wrap yarn also declines to a great extent simultaneously.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:

A kind of anti-cutting wrap yarn comprises core silk, middle level yarn, outer layer yarn composition, and described middle level yarn coats the core silk, outside at the middle level yarn is coated with outer layer yarn, and the core silk is the spandex silk, and described middle level yarn is formed by three layers, with the glass fibre is middle level core silk, the two-layer low elastic polyester filament of outside coating.Described core silk is the spandex silk, can make the anti-cutting wrap yarn have certain elasticity, the middle level yarn is to form by three layers, with the glass fibre is middle level core silk, the outside of middle level core silk coats two-layer low elastic polyester filament, outside at the middle level yarn is coated with outer layer yarn, and outer layer yarn is a superhigh molecular weight polyethylene fibers.Such wrap yarn has well wear-resistant, anti-cutting, tear-resistant.

As preferably, the sth. made by twisting of the outside two-layer terylene word bomb silk that coats of middle level core silk in the yarn of described middle level to be respectively " S " type twist with the fingers to " Z " type twist with the fingers to, terylene word bomb silk is that axis twines mutually with middle level core silk.The two-layer terylene word bomb silk of middle level yarn in being is the axis of middle level core silk with the glass fibre, twists with the fingers to twisting with the fingers to twining mutually with middle level core silk with " Z " type with " S " type, forms good comfortableness and wear-resistant, anti-cutting, tear-resistant performance.

As preferably, the sth. made by twisting of the two-layer terylene word bomb silk in the yarn of described middle level to be earlier " Z " type twist with the fingers to, carry out again " S " type sth. made by twisting to.Such canoe, more the institutional framework of wrap yarn is tighter, increases the performance of wrap yarn.

As preferably, described middle level yarn is that axis is twisted with the fingers to twining mutually with the core silk with " Z " type with the core silk, and described outer layer yarn is twisted with the fingers to twining mutually with the middle level yarn with " S " type, and described outer layer yarn is a superhigh molecular weight polyethylene fibers.

Therefore, anti-cutting wrap yarn of the present utility model, wear-resistant, the anti-cutting, tear-resistant that can significantly improve the anti-cutting wrap yarn, comfortable feel simultaneously, unit price also significantly descends.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structure enlarged drawing of middle level of the present utility model yarn.

The specific embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment: as shown in Figure 1, a kind of anti-cutting wrap yarn, core silk 1 is a spandex yarn, can make the anti-cutting wrap yarn have certain elasticity, be coated with " Z " type sth. made by twisting to the middle level yarn 2 that twines in the outside of core silk 1, be coated with the outer layer yarn 3 of " S " type sth. made by twisting to winding in the outside of middle level yarn 2, described outer layer yarn 3 is a superhigh molecular weight polyethylene fibers.

As shown in Figure 2, it is the middle level yarn 2 of anti-cutting wrap yarn, described middle level yarn 2 is formed by three layers, middle level core silk 4 is a glass fibre, can further improve the cutting resistance energy, be coated with two-layer terylene word bomb silk 5 in the outside of middle level core silk 4, one deck in the two-layer terylene word bomb silk 5 is twisted with the fingers to twining mutually with middle level core silk 4 with " Z " type, in addition one deck terylene word bomb silk 5 with " S " type twist with the fingers to twist with the fingers with " Z " type to terylene word bomb silk 5 coat mutually, low elastic polyester filament 5 can prevent that glass fibre from exposing, and can make yarn keep feel preferably again.

Special middle level yarn structure makes the anti-cutting wrap yarn have wear-resistant, anti-cutting, tear-resistant, the while comfortable feel, and unit price also significantly descends.
