Method of manufacturing multipurpose safety glove and multipurpose safety glove manufactured thereby
View Patent ↗The present disclosure relates to a method of manufacturing a multipurpose safety glove and a multipurpose safety glove manufactured thereby, and, more particularly, the present disclosure relates to a method of manufacturing a multipurpose safety glove and a multipurpose safety glove manufactured thereby in which a breakaway portion is not easily broken when general work is performed, so that a worker may be able to easily perform work tasks while wearing the safety glove. At the same time, safety requirements for the glove to be easily broken away from the hand in the case of danger are met, whereby a worker's body can be protected while maintaining working efficiency.
1. A method of manufacturing a multipurpose safety glove comprising a body portion, a finger portion, and a breakaway portion connecting the body portion to the finger portion and being separable by force pulling from the outside, the method comprising manufacturing the breakaway portion by:
twisting and weaving a first yarn insoluble in water and a second yarn comprising a water-soluble polymer; and
eluting a portion or all of the water-soluble polymer by treating the twisted water-soluble polymer with water.
2. The method of claim 1 , wherein an average fineness (A) of a fiber forming the body portion and the finger portion, and an average fineness (B) of the first yarn satisfy a following formula:
30≤ A/B≤ 70.
3. The method of claim 1 , wherein the water-soluble polymer comprises one selected from among polyvinyl alcohol (PVA), water-soluble acrylic polymer, polyethyleneimine (PEI), and water-soluble polyester.
4. The method of claim 1 , wherein the water soluble polymer has a melting point of 40° C. to 100° C. in water and the treatment with water in the eluting of the water-soluble polymer is performed at a water temperature of 40° C. to 100° C.
5. The method of claim 1 , wherein the first yarn comprises at least one selected from among nylon, spandex, polyamide, ultra-high molecular weight polyethylene (UHMWPE), polyolefin fiber, and polyester.
6. The method of claim 1 , wherein, in the twisting of the first yarn and the second yarn, the first yarn and the water-soluble polymer are mixed in a weight ratio of 1:2 to 4.
7. The method of claim 1 , further comprising coating a portion or all of the breakaway portion, simultaneously with or after eluting the water-soluble polymer.
8. A multipurpose safety glove comprising:
a body portion;
a finger portion; and
a breakaway portion that connects the body portion with the finger portion and can be separated by a force pulled from the outside, wherein the breakaway portion comprises a first yarn insoluble in water, and
wherein the breakaway portion has a tensile strength of 20 to 40 N when measured according to KS K 0520 standard, and satisfies a following formula:
30≤ A/B≤ 70
wherein A denotes an average fineness of a fiber forming the body portion and the finger portion, and B denotes an average fineness of the first yarn.
