In one embodiment, the tissue of the fabric may be any one tissue selected from the group consisting of plain weave, twill weave, weave weave, double weave, pile weave, weave weave, crepe weave, and combinations thereof, A pattern can be expressed on the fabric by using blended or colored yarns.

For example, when the plain weave, twill weave, and weaving weave are referred to as a three-way weave, the specific weaving method of each of the three-way weave is based on the conventional weaving method of each of the three-way weave, and the organization is modified or several pieces are used based on the three-way weave. It can be a fabric that can be changed by blending the texture, for example, as a variable plain weave, there are a duduk weave, a basket weave, etc., as a changeable twill weave, there are a new twill weave, a wavy twill weave, a non-twill weave, a ridge type twill weave, and an irregular weave weave as a variable twill weave. There are , middle-class, high-supply, and hwagang-supervised positions.

The double weave is a weaving method of a fabric in which either one of the warp or weft yarns is double or both are double, and the specific method may be a conventional double weaving method.

In addition, a pattern can be implemented on the fabric by blending the above various textures or using yarns of different colors to produce a door fabric, for example, dobby fabric, jacquard fabric, door fabric by mixing colored yarn and texture. can be manufactured.

More specifically, the dobby fabric is suitable for manufacturing a fabric having a relatively simple pattern, and can be used for the expression of extremely small patterns and checkered patterns completed by about 20 to about 40 weft yarns, for example, Pique (pique) weave, birds-eye (birds-eye) weave, waffle cloth (waffle cloth) weave, huekaback (huekaback) weave, crepe weave, and the like, but are not limited thereto.

The jacquard fabric is a fabric that can express a large pattern or curve differently from the dobby fabric, and may be, for example, brocade, damask, tapestry, etc., but is not limited thereto. .

The door fabric by the combination of color and texture can make a fabric with a small geometric pattern by mixing colored yarn, plain weave, basket weave, twill, etc. If all are alternately allocated one by one and weaving in plain weave, thin stripes in the warp or weft direction can be made. If two colors contrasting for warp and weft are used, and weaving in plain weave or basket weave, a crowfoot pattern can be created. can make In addition, two contrasting colored yarns are alternately arranged by 4 in the warp weft yarn, and a non-connected four-pointed star pattern can be expressed by weaving a 2/2 twill weave, and alternating the thin stripes in the warp direction and in the upper direction. Placing it can also implement a checkered pattern.

In one embodiment, the densities of the warp and weft yarns are not particularly limited when manufacturing the fabric, and for example, the basis weight of the woven fabric may be about 100 to 400 g/m 2 . If the basis weight of the fabric is less than about 100 g/m2, there may be a problem in that the mechanical strength of the manufactured functional clothing is lowered, and when the basis weight exceeds about 400 g/m2, the lightness of the manufactured functional clothing is reduced There may be a problem that activity is inhibited when manufacturing and wearing clothes.

The fabric thus prepared is cut and sewn to produce functional clothing. The fabric is applicable to both antibacterial and eco-friendly clothing products, for example, undergarments, socks, aprons, dishcloths, bed covers, sofa covers, scarves, eye patches, hair bands, and combinations thereof.
