Description

Method for producing the yarn that is containing the inorganic compounds, and the yarn made thereby and the fabric is weaving to use them}

The present invention relates to a method for producing a spun yarn containing an incombustible inorganic component, the spun yarn and a fabric using the spun yarn, and more particularly, impregnated a non-flammable inorganic component into short fibers made of regenerated fibers, and impregnated with the non-combustible inorganic component. Spinning the recycled fibers in a conventional spinning process to produce a yarn containing a non-flammable inorganic component, and relates to a non-combustible fabric, such as interior weaving room, medical fabrics using the yarn.

In order to manufacture non-combustible fabrics (interior fabrics, living fabrics), non-combustible fabrics are manufactured using non-combustible materials such as carbon fibers, aramid fibers, and inorganic metal fibers, which are special materials. It is the development of non-combustible fabrics using recycled fiber spun yarn containing the proper amount of ingredients, and can be used for many purposes (interior and medical fabrics), and it is also developing non-combustible fabrics with excellent dyeability.

That is, until now, the non-combustible fabric weaving industry has tried to meet the standards of fire by weaving a variety of non-combustible, semi-combustible, flame retardant fabrics.

For example, in the case of upholstery fabric or partition fabric, weaving is made of natural or synthetic fibers, and then flame retardant or flame retardant is processed through post-processing.

Korean Patent Publication No. 10-1073377 (2011.10.13.) Is coated with a non-combustible composition comprising an aqueous acrylic resin, a phosphorus-based flame retardant, a catalyst, a dispersant, a pigment, an ultraviolet (UV) stabilizer, and a crosslinking agent on a spun yarn fabric made of natural materials. Thus, a non-combustible sheet embedded fabric using a blended spun yarn is disclosed which can develop a non-combustible sheet embedded fabric using fibers of natural or recycled materials without using a semi-combustible material made of a special material.

However, flame retardant processing or flame retardant processing is not only complicated and cumbersome in its processing steps, but also the flame retardant fabrics produced through this process have high production costs, resulting in poor economic efficiency and flame retardant function, and depending on the material and use of the fiber. There is a problem that cannot be applied multivariately.

In addition, since the color is monotonous and not a high-quality processing method to be heat-treated at a high temperature (175 degrees or more) during the flame retardant treatment by post-processing there is a problem that the texture of the fabric can not be maintained.

In addition, in the interior fabrics used in curtains, sofas, chairs and partition fabrics, buildings, theaters, cabarets, hotels, hospitals (medical fabrics), the dyeability required with the non-flammable and flame-retardant function is inevitably deteriorated. There are many problems in the tissue structure of the fabric, such as falling.

In order to solve the problem that the dyeing is not easy, Korean Patent No. 10-1094629 (2011.12.15.) Has a double fabric using a warp and weft yarn using two kinds of fibers of polyester fiber and non-flammable glass fiber. Woven semi-combustible fabrics are disclosed. The semi-combustible fabric has an advantage that can be expressed in a variety of colors, but there is a problem that the non-combustibility is not enough as using the polyester fiber.

Generally, non-combustible interior fabrics are manufactured using yarns made of non-combustible materials such as carbon fibers, aramid fibers, and inorganic metal fibers, which are special materials, but special materials such as carbon fibers, aramid fibers, and inorganic metal fibers are incombustible. This was an excellent but not easy dyeing problem.
