The present invention relates to an environmentally-friendly water-soluble coating agent applied to a nylon fiber fabric, a method of producing a fiber fabric using the same, and a breathable down fabric prepared by the method. More specifically, the fabric is made of nylon, (Polyol) and OCN-3H on the surface of the nylon fiber fabric woven with 162 ~ 310 strands per 1 inch, and the density of the weft yarns is 7 ~ 20 deniers. 30 to 45% by weight of polyurethane solid coating composition prepared by reacting R-Nco (isocyanate) to form [-CONHRNHCooR-] _N (polyurethane), 35 to 65% by weight of water, To 20% by weight of a water-soluble coating agent, and then applying a water-soluble coating agent having a viscosity of 5,000 to 2,000 cps at a temperature of 15 to 25 ° C.

Generally, a down-product manufactured by charging a duck-down or goose down as a thermal insulation material is not only used as a winter clothing and a bedding but also recently being popular as an outdoor clothing.

In a garment or bedding product produced by including a filler between a doughed surface and a lining, the filler contained in the product during its manufacture or use may cause various phenomena such as lump, movement, and overlapping, thereby causing various inconveniences.

If the filler is a cloth like fabric, the problem can be avoided by fixing the edges of the filler together at the edge of the product.

When the filler is a continuous material such as cotton or wool, the lining, the outer material, and the filler therebetween may be sewn together or stitched in a manner of molding to prevent migration or aggregation of the filler.

When the filler is a discontinuous material such as goose down and goose down, it is difficult to fix by the above-mentioned stitching or quality method, so that a compartment is formed between the lining and the outer surface to prevent movement or jamming.

The down compartment is generally formed by connecting the lining and the outer surface with a connecting line or a connecting line for separating the compartment, and the compartment formed by the connecting line for separating the lining, the surface and the compartment is charged down. The down jacket can be formed by sewing together the lining and outer cloth at regular intervals to form a sewn line compartment wall and overlocking the lining and the open edge of the outer cloth together to form a spatially sealed down compartment.

Down products having such down compartments as described above can prevent downward movement or panning, but can also be provided with infiltration of dew and moisture through the fabric itself, exudation of down through the sewing or puncturing holes and inflow of moisture, There is a problem that the production cost is increased due to the sewing process for forming.

Down exudation through the fabric itself can be relatively easily prevented by using a down-proof fabric or a coated or laminated functional fabric. Functional fabrics, such as waterproof breathable fabrics or breathable fabrics, are produced by surface treatment, film coating or multi-layer construction, which not only prevents the exudation of down through the fabric itself, but also the inflow of moisture through the fabric itself And it is also possible to prevent the phenomenon that the downflow due to the introduced moisture becomes damp and the generation of odor.

An intercalation sewing method in which a sewing hole is sealed by inserting an insertion fabric or an adhesive band between the lining and the fabric to prevent downflow and moisture inflow through the sewing hole or the needle hole, A sewing-line sealing method for preventing the downward exudation through the sewing holes and the moisture from entering and sealing by adhering / fusing the edges after covering the edges, and bonding the fabrics without using the sewing method or the fusing method A seamless bonding method and the like have been proposed.

On the other hand, in the field of manufacturing down products, down-sizing and movement can be solved to some extent through the formation of compartments, while the additional sewing process for forming such compartments is laborious and time- I raised the problem.

In addition, such a sewing process has a problem in that mass production is difficult because of difficulty in mechanization.

As a non-sealing method which does not use such man-hours and time-consuming sewing processes, there has been proposed a bonding method using an adhesive and a fusing method using a fabric fusing process. However, these bonding methods and fusing methods have become laborious and time- However, practical use has been limited in the actual manufacturing site due to the damage of the fabric due to the fusing of the fabric, the restriction of the selection of the fabric, and the lack of the bonding strength and durability by the heat-

In such a situation, there has been continued research on a method for forming a separating divider between the lining and the outer surface using an adhesive so as not to cause problems of adhesion, adhesion durability and adhesive line finishing
