One side of the fabric is hydrophilic and absorbs sweat or water and the other side of the fabric is water repellent and does not absorb and bounces sweat or water. The method for manufacturing the one side water repellent fabric, one side of which is hydrophilic and the other side of which is water repellent, includes: a step of preparing a predetermined viscosity of water repellent made up of a mixture of polytetrafluoroethylene, paraffin, pyroligneous liquor, chitosan, hydrogen, melamine resin, and silicone resin; a step of dipping an application roller into the water repellent; a step of scrapping and removing the water repellent from the application roller with a water repellent remover such that a predetermined thickness of the water repellent is left; a step of allowing one side of the fabric to be coated with the water repellent with a thickness of 0.010 to 0.025 mm by passing the fabric between the application roller and a non-application roller; and a step of drying the water repellent-coated fabric by passing it through a drying chamber.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water repellent fabric,

The present invention relates to a water-repellent material and a method for producing the same, and a water-repellent material having water-repellent properties such that one side of the fabric has a hydrophilic property to absorb sweat and water and the other does not absorb sweat or water, .

Generally, unlike the method of dipping the entire fabric into the aqueous solution, the single-sided water-repellent (or single-side absorbing) process is a fiber finishing technique in which only one side of the fabric is subjected to water repellent treatment. It can be usefully used for fabrics of functional garments.

Especially, it is used for processing fabrics using sweat-absorbing quick drying (sweat-absorbing and quick-drying) yarns that absorb sweat and secretions from the body, such as Aerocool and Cool max, It is expected that the quality of sports wear and leisure clothes can be improved more ergonomically.

Therefore, there is a need for a method of fabricating a web as disclosed in Korean Patent Publication No. 10-1132061, which comprises the following steps: a) de-oiling a fabric to remove water repellency of the fabric; b) dipping the deodorized fabric in a photocatalytic solution to form a photocatalyst layer on both sides of the fabric; c) heat treating the fabric having a photocatalyst layer on both sides thereof; and d) water repellent processing of one side of the fabric.

However, in the above-described method of water-repellent processing of a fabric, it is impossible to apply the water-repellent agent to the fabric with an accurate thickness because the water-repellent agent does not have a viscosity, The thickness of the fabric can not be varied, so that there is a problem that the touch feeling on the fabric having different thicknesses can not be satisfied.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted so as to avoid obscuring the subject matter of the present invention.

One side of the fabric has hydrophilic property to absorb sweat or water and the other side has water repellent property to repel without absorbing sweat or water but it is applied by having a device for removing the water repellent agent on the application roller As shown in FIG. 1, the method for preparing a water-repellent layer according to an embodiment of the present invention, which is applied with a different thickness depending on the thickness of a fabric, includes a step of preparing a viscous water- , A water repellent agent removing step (S13), a water repellent agent applying step (S14), and a fabric drying step (S15).

1) Preparation of viscous water repellent agent (S11)

The water repellent agent 10 according to the embodiment of the present invention is prepared by mixing polytetrafluoroethylene, paraffin, wood vinegar, chitosan, hydrogen, melamine resin, and silicone resin at appropriate ratios and having a viscosity of a predetermined viscosity.

For example, the water repellent agent 10 may include 10 to 45 wt% of polytetrafluoroethylene, 15 to 25 wt% of paraffin, 5 to 15 wt% of wood vinegar, 6 to 15 wt% of chitosan, 10 to 20 wt% of hydrogen, 8 to 15% by weight of a resin, and 2 to 10% by weight of a silicone resin are used as a mixture. Alternatively, mixtures of various types may be used.

The water repellent agent 10 of the present invention may further contain one or more adjuvants such as a far-infrared ray emissive agent, an ultraviolet screening agent, a fragrance, an antistatic agent, an antibacterial agent, a bactericide, a deodorant and a deodorant. The adjuvant may be any known one, and there is no particular limitation thereto.

The viscosity of the water repellent agent (10) is commercially available, and it is possible to use an appropriate viscosity enhancer harmless to the human body.
