In general, natural dyeing refers to the process of applying color to fabrics using vegetable, animal or mineral dyes. The characteristics of such natural dyes are that the color saturation is not high compared to chemical dyes, and there are many eco-friendly and human-friendly elements.

Compared with synthetic dyeing, natural dyeing has advantages in that the color is natural, the aesthetics are excellent, and the natural material is processed into a dye to have the functionality such as antibacterial, deodorizing and anti-allergic properties as natural dyeing. In addition, natural dyes have the advantage that they do not cause problems with wastewater and odors incidental to the use of synthetic dyes, and have affinity for the environment.

As an example of the prior art, Patent Publication No. 2015-105529 discloses a dyeing method using a persimmon dye and a natural dye. However, in the prior art described above, not only pure persimmon is used, but a process of pre-treating the fabric with soybean juice to prevent the occurrence of dyes and stains extracted from natural dyes is required, thereby increasing the dyeing process and cost, resulting in economic feasibility. And there was a problem that productivity is lowered.

In addition, the hollow fiber may have a number of 24 to 72 filaments, preferably, may have a number of 24 to 48 filaments.

If the hollow fiber is less than the number of 24 filaments, there may be a problem in that the unique feel of the fiber is reduced, and if the number of the hollow fibers is greater than 72 filaments, there may be a problem of fiber aggregation and thermal insulation deterioration.

On the other hand, the sponge can be used without limitation as long as it is a sponge capable of performing double-sided bonding, preferably, it may be a sponge of a bonding material for clothing that is soft, flexible, and has a shape retention feeling and light weight.

In this case, the sponge may have a thickness of 0.8 to 5.0 mm, preferably 0.8 to 1.2 mm.
