Description

Functionality protection suit

The present invention relates to a functional protective clothing, using a functional fabric having heat retention, antibacterial properties and far-infrared radiation as a lining, and laminated using a fabric having protection against water and bacteria penetration while having breathability as an outer material, but as a lining It relates to a functional protective clothing in which the functional fabric used is formed into a triple weave structure to improve heat retention and antibacterial properties and, in particular, to further improve far-infrared radiation.

In general, functional protective clothing is used in chemical and semiconductor laboratories, laboratories, chemical plants, waste treatment plants, asbestos removal workshops, tank cleaning workshops, bio facilities, pharmaceutical manufacturing facilities, etc. It is worn to protect the body of workers from fine dust and harmful chemicals and to maintain a clean working environment.

In addition, functional protective clothing is worn by firefighters and safety personnel or used to protect against harmful substances such as various medical drugs, microorganisms, bacteria, and viruses that occur in medical facilities such as hospitals, government and local governments, and quarantine centers.

Since these general functional protective clothing have poor thermal insulation function in winter, especially when working for a long time in a screening clinic where the outside air is not blocked, it is not only inconvenient to have to wear several layers of clothing in the protective clothing to keep it warm, There are problems with many restrictions.

Also, in the prior patent technology for functional protective clothing, Patent No. 10-2313036 'protective clothing for blocking chemical substances with improved antibacterial function' is known, which is a polypropylene nonwoven fabric, as shown in FIG. The antibacterial composition is applied and dried to form an antibacterial treatment, but the antibacterial composition is formed by including an ethanol extract of Stregia leaf and an ethanol extract of Achiote fruit in a weight ratio of 4:6 to 6:4, which is Korean Industrial Standard KS As a result of the antimicrobial test according to K 0693-1990, it was judged to be acceptable.

However, the functional protective clothing of the prior art has a problem in that it is difficult to uniformly apply the antibacterial composition in a plain weave fabric, so that the antibacterial property is partially lowered, and also there is a problem that the heating performance is deteriorated because it does not have a far-infrared radiation function.

Also, in other prior patents related to functional protective clothing, Patent Registration No. 10-1398007, 'electrospun composite nanofibers containing germanium and silicon dioxide' is known, which is a nanofiber of germanium and silicon oxide in PVA through an electrospinning process. It is a technology that encapsulates particles to form Ge/SiO ₂ composite nanofibers to have far-infrared radiation and antibacterial performance.

More specifically, as a result of measuring the far-infrared emissivity and radiant energy according to the concentration of Ge and SiO ₂ of the composite nanofiber containing germanium and silicon oxide nanoparticles, the composite nanofiber containing 0.5wt% of Ge _and 1wt% of SiO2 has a far-infrared emissivity of 0.891 and an excellent far-infrared radiation ability of 3.44×102W/ ^{m 2} It shows a 99.9% reduction in bacteria for cocci and E. coli, but a 34.8% reduction for pneumococci.

However, the other prior patent technology, although the bacteria reduction rate of 99.9% for Staphylococcus aureus and E. coli occurs, the reduction rate of bacillus pneumoniae is low, so it is somewhat suitable to provide a protective suit for managers of patients with pneumococcal infectious diseases such as the recently popular Corona 19 There are issues that do not exist.

Also, in another prior patent technology related to functional protective clothing, there is known Patent No. 10-1345899, a three-layer thermal insulation fabric for agriculture, which, as shown in FIG. Divided into warp (3), weft yarn is divided into surface layer weft yarn (4), double layer weft yarn (5), and feed weft yarn (6). The surface fabric and the double layer are woven in a double weave so that the surface fabric 7 and the double layer fabric 8 are composed based on the connecting line 9, and the surface layer fabric and the double layer fabric are woven in a double weave for agriculture in which a feeding weft is located between the surface layer fabric and the double layer fabric Further provided with a feeding weft diagonal to the feeding weft located at the hollow point composed of the fabric, and the feeding weft and the feeding slope are placed in a non-woven state so as to become a bulky holding part 11 at the point adjacent to the connecting line. , by placing a plain weave part 12 on the inside, it is composed of a three-layer weave that becomes a surface layer fabric, a plain weave part, and a double layer fabric.

In another prior patent technology, the thermal insulation fabric is woven in a triple weave to improve the thermal insulation, but since the surface layer weft and the double weft yarn are combined weaving in one stitching warp, the joining warp to be combined is easily damaged, and accordingly, the triple weave fabric There is a problem that a part of it is separated and swells.
