Description

Processing method of glass yarn and cut resistant gloves made therefrom {Method of covering glass yarn and cut resistant gloves made therefrom}

The present invention relates to a processing method of a glass yarn and a cut preventing glove manufactured therefrom, and more specifically, to knit an industrial (cutting prevention) glove using a glass yarn, after covering the glass yarn with nylon yarn under appropriate covering conditions. The present invention relates to a processing method of a glass yarn and a cut-protective glove manufactured therefrom to improve cutting resistance and abrasion resistance as well as providing a comfortable fit and stability as a single yarn is made of a composite yarn obtained by covering it with a high density polyethylene yarn.

In general, industrial safety products such as masks, dustproof clothes, gloves, safety shoes, and the like are used to prevent accidents of workers in various industrial sites dealing with metal, glass, steel, and the like.

In particular, gloves must be worn to protect workers' hands from various harmful factors such as physical friction, machine malfunctions, sharp objects, etc. in workplaces where cutting protection is required.

The cut-resistant gloves are currently being managed in a number of countries, such as Europe or the United States, through strict standard conditions, for example, European safety standard EN-388, the quality control, based on the cutting strength of the gloves currently required in the market ( Blade cut resistance specification is performance level 5 or so.

In order to satisfy these standard conditions, most domestic manufacturers have used high-density polyethylene yarn, Dyneema yarn, developed by DSM of the Netherlands. Dyneema yarn is light, yet has high strength and stability. It has excellent impact resistance and heat resistance, and is being widely applied in various fields.

However, Dainima Co., Ltd., because the manufacturing cost is so expensive and limited in use due to patent royalty problems, alternatively, by adding wire or glass yarn to fibers such as polyester or nylon, the strength is increased by knitting gloves. Although a method of reinforcing has been used, such a glove has a problem that it is not suitable for processing a complex small part, such as an increase in strength but a lack of elasticity or a feeling of wearing, resulting in an uncomfortable hand movement.

The present invention is to solve the above problems, by adjusting the covering conditions with a composite yarn obtained by processing a glass yarn so as to replace the conventional Dyneema yarn glove with improved cutting resistance and wear resistance and stable fit It is an object of the present invention to provide a processing method of glass yarn and a cut prevention glove manufactured therefrom.

In addition, another object of the present invention is to reduce the defective rate during the knitting process of gloves to improve workability and productivity.

In order to achieve the above object, the processing method of glass yarn according to the present invention and the cut prevention glove manufactured therefrom are made of glass yarn as a screening, and after double covering nylon yarn as the covering yarn around the glass yarn, It is characterized in that the composite yarn of one set is obtained by covering it with a high density polyethylene yarn again.

Here, when the glass yarn is covered with nylon yarn, it is preferable that the number of revolutions per minute of the covering machine is adjusted to 4,500 to 5,500 rpm and the twisting coefficient is adjusted to 900 to 1,100TM.

In addition, the glass yarn is 100 ~ 400 denier 1 go, the nylon yarn is selected from 70 denier 2 or 140 denier 2 go, the high-density polyethylene yarn is preferably 450 denier 1 go.

In addition, the cut prevention glove according to the present invention is characterized in that it is produced by a single knitting by a known method using a composite yarn obtained according to the above method.

As described above, according to the processing method of the glass yarn of the present invention and the cut prevention glove manufactured therefrom, by manufacturing the glass yarn by appropriately adjusting the covering conditions to produce a glove with improved strength, such as wear resistance, cut resistance Therefore, even in various industrial sites involving dangerous work, the worker can safely use the product without worrying about injuring his hand, and extends the life of the product.

In addition, the composite yarn obtained under the covering conditions has one advantage that the workability and productivity are improved because there is no fear of a defect occurring in the knitting process of the gloves.

Moreover, since the composite yarn obtained in the present invention can partially replace the use of expensive Dyneema yarn, the overall manufacturing cost can be significantly lowered, and thus the price competitiveness can be secured.

FIG. 2 is a perspective view illustrating a state in which the nylon yarn circumference of FIG. 1 is covered with high density polyethylene yarn again;
Figure 3 is a picture substitute photograph showing a glove knitted with a glass yarn processed according to the present invention

Hereinafter, a preferred embodiment of a glass yarn processing method and a glove manufactured therefrom according to the present invention will be described in detail.

Referring to the drawings, the processing method of the glass yarn according to the present invention, by covering the nylon yarn (2) around the glass yarn (1), to cover the high-density polyethylene yarn (3) again to produce a composite yarn for gloves However, when covering the glass yarn with the nylon yarn, the rotational speed per minute of the covering machine is adjusted to 4,500 ~ 5,500rpm, preferably 5,000rpm, the twist coefficient is 900 ~ 1,100TM, preferably 1,000TM, and these are back to the high-density polyethylene yarn The number of revolutions per minute of the covering at the time of covering is 2,800 ~ 3,200rpm, preferably 3,000rpm, the twist coefficient is characterized in that the covering is adjusted to 180 ~ 220TM, preferably 200TM.

This will be described in detail according to the processing of glass yarn and the knitting order of gloves.

[1] primary coverings

In the present invention, one set of 100 to 400 denier glass yarns is used as a core yarn to be placed in the center.

At this time, since the glass yarn 1 is thin and soft, and may use a single yarn, the glass yarn 1 may be easily broken or broken, so that the glass yarn 1 is protected by double covering the circumference with a covering yarn 2 made of elastic fibers.

The covering yarn (Covered Yarn) is selectively used according to the desired thickness of two dens of 70 denier nylon yarns or two double 140 denier nylon yarns to cover with a covering machine (Covering machine).

That is, after selecting one of two 70 denier or 140 denier nylon yarns as a covering yarn, and as shown in FIG. 1, each of the nylon yarns 2 in the state centered on one glass yarn 1 1 roll in a spiral form alternately from left to right Double covering.

Here, the rpm of the covering machine is preferred to be 4,500 ~ 5,500rpm, if, if the rpm is set higher than 5,500rpm single yarn glass yarn may be easily broken or broken during the covering process thereafter gloves The cut resistance required for knitting cannot be obtained.

On the other hand, if the rpm of the covering machine is set too low than 4,500 rpm, workability and productivity are deteriorated.

In addition, the twisting coefficient of the covering machine (TM: Twist per meter) is preferably adjusted to 900 ~ 1,100TM, which, like the rotational speed per minute, if the twisting coefficient is set too high exceeding 1,100TM glass yarn is easily broken On the other hand, if it is set lower than 900TM, workability, productivity is lowered, so it is necessary to appropriately adjust it as described above.

[2] secondary coverings

Subsequently, the glass yarn 1 is covered with nylon yarn 2 and then covered with one set of 450 Denier High Density Polyethylene yarn.

At this time, the number of rotations per minute of the covering machine is 2,800 ~ 3,200rpm, the twisting coefficient is adjusted to 180 ~ 220TM to cover.

As the high density polyethylene yarn 3, fibers such as Dyneema or Spectra may be used.

The composite yarn 4 made under the covering conditions as described above is highly suitable for knitting with industrial gloves due to improved cutting and abrasion strength, and such composite yarn is made of one go, that is, one strand, so that workability is good. You have an advantage.

In other words, conventional gloves are knitted by putting two or three strands of composite yarn into a glove knitting machine. In this case, if even one strand is cut in the knitting process, defects (abnormalities) occur and the machine operation is automatically stopped. This problem is eliminated in the present invention.

[3] knitting gloves

Using the composite yarn (4) as described above, while knitting a glove (G) by a known method, it is a single knit.

Gloves knitted in this way can be used as an industrial glove because it is improved in cutting resistance and abrasion resistance by glass yarn, further improved in cut resistance by nylon yarn and high-density polyethylene yarn, and given elasticity and comfortable fit. there was.

[Test Example 1]

First of all, 200 denier glass yarn is used as the screening, 140 denier nylon yarn is made of 2 coverings, and the covering is set at 5,000 rpm and the twisting rate of 1,000 TM for double covering. A composite yarn is prepared by covering 1 rpm of high density polyethylene yarn with a rotation rate of 3,000 rpm and a twist coefficient of 200 TM.

After coated with polyurethane in a glove knitted with the composite yarn was subjected to a strength test based on the EN 388 standard as a sample and the results are shown in Table 1 (Test Institution: CTC Asia Ltd.).

In this test, the wear, tear, and puncture strengths of the four samples were measured and the lowest values were indicated.

Figure pat00001

According to the results of Table 1, the glove made of a composite yarn obtained by the glass processing method of the present invention is subjected to various risks as the cutting strength, wear strength, etc. meet all the quality conditions required by the European standard. It was found that it can be safely used in industrial sites.
