Description

Coated gloves with excellent cutting strength, grip and chemical resistance and improved wearing comfort

The present invention not only satisfies cutting strength, grip and chemical resistance of ANSI 5 or higher level without increasing the thickness and weight of the glove, but also improves the fit and feel of the glove and the ease of coating latex. It is about coated gloves that do.

In general, coated gloves are coated with latex (latex, natural rubber latex, synthetic rubber latex, other synthetic resin latex, etc.) These gloves are breathable and waterproof.

However, the coating gloves as described above generally have the disadvantage of insufficient cutting strength, gripping property and chemical resistance, and recently, research and development to supplement them have been actively conducted.

As a related prior art, in Patent Document 1, double covered yarn (double covered yarn) made by covering glass fiber yarn with polyester or nylon elastic fiber yarn and HPPE (high performance polyethylene, high-strength polyethylene) yarn to improve cutting strength , Gloves are knitted with a single covered yarn that covers the HPPE yarn on the elastic fiber yarn, and the double cover yarn knitted part with enhanced cutting strength on the outside and the cut resistance and elasticity on the inside at the same time By positioning the cover yarn knitted part, a glove is proposed in which the cutting resistance property to protect the hand is strengthened and the elasticity to improve the wearing comfort is maintained.

However, in the case of Patent Document 1, although the cutting strength can be slightly improved by using glass fiber, nylon or HPPE yarn, in the case of glass fiber, fine particles or fluff due to breakage are absorbed or contacted with the human body Not only does it have adverse effects (tingling, etc.), but the actual cutting strength is not excellent due to the above cracking phenomenon. Moreover, in the case of nylon, when it is exposed to chemicals or needs to be washed with water, it is easily melted and damaged during work due to its low chemical resistance. There were problems such as sticking to the .

On the other hand, in recent years, attempts have been made in Japan to weave gloves using liquid crystal polyester yarn, which has excellent cutting strength, but liquid crystal polyester yarn has poor chemical resistance and a very slippery surface. There was a problem that war latex could not be coated or was easily peeled off even if coated.

On the other hand, in the case of 'Kevlar' fiber, as an aramid-based fiber, Patent Document 2 discloses a prior art of weaving gloves using the Kevlar fiber as described above.

However, in the case of the Kevlar, although it has the advantage of excellent heat resistance, the cutting strength is very weak, and in particular, since the surface is made of fine wool, there is a problem that the latex cannot be coated.

In addition, in the case of general cut-resistant gloves, the limit is ANSI (American National Standards Institute) 3 to 4 levels, and excessive use of the above functional yarns to reach level 5 results in thick and heavy gloves. There was a problem in that the wearing comfort and workability were significantly deteriorated.

Patent Document 1: Republic of Korea Patent Registration No. 10-0767452 "Work gloves with enhanced cut resistance" Patent Document 2: Republic of Korea Patent Publication No. 10-2010-0012668 "Polyurethane foam coated with water-dispersible polyurethane resin with excellent water repellency and manufacturing method thereof"

In the present invention, in a coated glove coated with latex on a glove, the outer knitting part knitted with the double cover yarn 10 containing the tungsten yarn (T) and the inner knitting part knitted with the short cover yarn 20 or ordinary yarn However, the double cover yarn 10 is made of HPPE yarn (H) or PET yarn (P) on the surface of the tungsten yarn (T) or the plying of tungsten yarn (T) and span yarn (S) as a core The first covering and the second covering with PET yarn (P) or HPPE yarn (H) on the surface are used, and the short cover yarn 20 is covered with PET yarn (P) on span yarn (S) A coating glove with excellent cutting strength, grip and chemical resistance and improved wearing comfort, characterized in that the general yarn uses PET yarn (P), as a means of solving the problem.

Here, the tungsten yarn (T) used for the double cover yarn (10) is composed of 1 to 2 strands of tungsten yarn (T) having a thickness of 18.5 to 19.5 μm, and the HPPE yarn used for the double cover yarn (10) (H) has a thickness of 200 to 400 denier, the PET yarn (P) used for the double cover yarn 10 has a thickness of 75 to 150 denier, and the span yarn used for the double cover yarn 10 (S ) is preferably 40 to 50 denier in thickness.

The span yarn S used for the short cover yarn 20 has a thickness of 40 to 50 denier, and the PET yarn P used for the short cover yarn 20 or the general yarn has a thickness of 40 to 50 denier. 75 denier is used, but it is preferable to use DTY or spun yarn thereof.

The present invention is a coated glove in which latex is coated on the surface of the glove, and simultaneously satisfies ANSI 5 or higher cutting strength, grip, and chemical resistance without increasing the thickness and weight of the glove, as well as the fitting and tactile feel of the glove. There is an effect of improving the comfort of the back and the ease of coating of latex.
