Description

Fabric having excellent air permeability, antistatic property and method for manufacturing thereof

The present invention relates to a fabric and a method for manufacturing the same, and more particularly, to a fabric having excellent air permeability and excellent antistatic properties, and a method for manufacturing the same.

In general, sports clothing is more convenient for athletes and ordinary people to wear and exercise when exercising, the movement of the body increases compared to usual and movement of the body increases. You will wear sportswear made of fabric. As described above, in recent sportswear, sportswear made of functional fabrics having various functions such as ventilation, waterproofing, windproofing, and antibacterial, as well as allowing the wearer's body movement to be made comfortable, are becoming the mainstream.

In addition, in manufacturing fabrics, polyester fibers are widely used. Existing polyester fibers are widely used due to their excellent properties, but they have high electrical resistance and high static electricity, which adversely affects the work during spinning and processing. There is a problem of discomfort due to static electricity even when using the product. Therefore, many studies have been conducted on a method of imparting antistatic properties to polyester.

As such, it is important to ensure air permeability as well as antistatic properties as a function of the fabric, but there is a limit to manufacturing a fabric that satisfies both of these two functions excellently.

Accordingly, there is a need for a fabric having excellent breathability and excellent antistatic properties and a method of manufacturing the same.
