Description

FUNCTIONAL COTTON GLOVES FOR WORKING AND MANUFACTURING METHOD THEREOF

The present invention relates to a functional working cotton gloves and a method for manufacturing the same, and more particularly, to a functional working cotton gloves having excellent wear resistance, flame retardancy and solvent resistance by coating the coating liquid on the cotton gloves woven with cotton yarn, and a manufacturing method thereof.

Generally, work gloves are woven into cotton yarns and are worn to protect workers' hands at various industrial sites. These work gloves can protect the hands of workers, but they are not waterproof at all, so when you catch wet items with moisture or oil, moisture or oil flows into the cotton gloves to wet the cotton gloves and hands, making them comfortable to wear. This is not good, especially when oil is introduced, it is difficult to wash hands by contaminating the hands, as well as causing dermatitis.

These discomforts come from natural rubber and latex, which are now widely used on cotton gloves, and vulcanized, and rubber coated cotton gloves are used. They are excellent in performance and good, but are weak in petroleum solvents and are therefore restricted. Products were expected to replace.

In order to solve the above drawbacks, a work glove coated with a polyurethane-coated cotton glove, ie a synthetic resin material, has been developed. Work gloves coated with a synthetic resin film as described above is widely used to prevent the penetration of moisture or oil into the outside of the cotton gloves woven with cotton yarn and to prevent slipping during work.

As an example of the work cotton gloves coated with a synthetic resin film, there is a patent No. 10-073400 (hereinafter referred to as "pre-registered patent") patented under the name of "work cotton gloves formed of a synthetic resin film and a manufacturing method thereof".

The prior patent is coated with a coating of polyurethane (polyurethane) first on the surface of the cotton gloves woven with cotton yarn, then coated with a plastisol (Plastisol) of polyvinyl chloride (Plastisol) as an interlayer. And a coating of polyurethane was completed on top of the plastisol to complete the film formation.

However, the above registered patent is complicated by coating a synthetic resin material on the surface of cotton gloves by performing three coating processes such as polyurethane formation, plastic sol formation and polyurethane formation. In addition, there has been a problem in that flame retardancy is not good because a flash point is formed by forming a film in which polyurethane, plastic sol and polyurethane are laminated.

In addition, the pre-registration license is a plasticizer such as DOP (Dioctyl Phthalate) and DBP (dibutyl phthalate) as a plasticizer of the plastisol, there is a problem that is not environmentally friendly by generating environmental hormones.

Domestic Patent No. 10-0903700 (Registered June 11, 2009) Domestic Patent No. 10-1070687 (registered September 29, 2011) Domestic Patent No. 10-1349820 (January 03, 2014 registration)
