Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a material for a sportswear having excellent functionality such as light heat performance using a nanomembrane and a manufacturing method thereof,

The present invention relates to a fiber product used as a material for sportswear, more specifically, a cost-saving nanomembrane material having superior moisture permeability and water resistance, And also to develop a comfortable sportswear fabric product which has antistatic function, antimicrobial, deodorant, light heat performance, etc., which is excellent in complex functionality by applying PET side by side yarn.

Recently, due to the improvement of people's standard of living, the market size of textile products for sportswear is gradually growing, consumer interest is also rising due to the increase of leisure time and 5-day working week, and the ISPO trend of 2014 ~ 2015 As noted, attention is focused on differentiated technologies that simultaneously demand advanced functions and complex functions based on surface effects.

Therefore, consumers are increasingly demanding products with excellent functionality such as heat insulation and moisture-proof and waterproof property by increasing the outdoor activities of consumers and increasing the utilization to the casual wear. In addition, We believe that domestic and foreign brand experts will continue to increase the market for the wear and tear.

Up until now, textile products for sportswear have been used for simple application of PET and nylon materials or for breathable waterproofing products for outdoor use. However, since most of them do not have complex functions or are limited to some imported products, It is a big fact.

Therefore, by applying nano-membrane using electrospinning and high-low-viscosity PET side-by-side yarn capable of exhibiting ultraviolet shielding function, it is possible to provide various functions such as light heat (+3) performance (breathable waterproof, stretch, antibacterial, It is a reality that it is a reality to develop localization technology that can differentiate by function superior to imported products and reduce cost by developing textile product with anti-static.

On the other hand, if you look at the current state of the technology for sportswear, there is a high interest in heat-generating materials in overseas countries. Especially, famous yarn makers and material companies in Japan are researching and developing various kinds of heat- As a representative product of U company, 'Heattech' is a product that has received much attention in domestic market. In addition, Japanese brands are making a lot of efforts to develop thermal materials in accordance with the necessity of thermal insulation materials. Especially, There is a great deal of interest in heating materials and much research has been done.

At present, the domestic environment of moisture-proof tarpaulins is inferior to the products of European advanced countries due to the lack of development of processing technology. In case of dry or wet processing method using organic solvents, the problem of environmental inhibition is neglected. GORE-TEX has dominated the high-end market, followed by Dore's Entrant, Shimpatex, and Aquatore.

Since GORE-TEX Membrane is hydrophobic, water vapor that emanates from the body escapes through the space of porous form, so it has excellent water-proof and breathable characteristics and maintains dry feeling when worn. On the other hand, if it exceeds the water vapor emission limit region, there is a great disadvantage that dew condensation occurs on the coating film surface. Membranes such as Shimpatex and Entrand are hydrophilic, so that water vapor from the body is radiated to the outside through the porous space, and at the same time, it is absorbed into the coating film layer and releases the wall.

Thus, when a lot of sweat is absorbed by the film layer, there is a big disadvantage that it gives a moist feeling when it is worn for a long time. However, since these laminating clothing materials are also expensive and depend on imports, there is an urgent need to develop laminating materials for clothes that can compete with domestic and international competitors by complementing the aforementioned merits and drawbacks .

G has been sold worldwide with a number of breathable and waterproof products. However, due to sales of film-based products, not only the unit price of the high price zone is formed but also fabrics that can demonstrate its functionality are not sold. And they are all dependent on imports.

As light heat products, omnihit of company C and body heat of company B are widely used as materials for underwear and outdoor, because they have excellent heat generating performance. However, in the part of antistatic effect which causes winter problems, have.
