One aspect of the present application, coffee bean fiber, corn fiber and pineapple fiber to cover the water-soluble polyurethane fiber to the blended yarn blended to prepare a covering yarn; Preparing a composite yarn by mixing chitosan fibers and seaweed fibers with a polyester resin and a water-soluble polyurethane resin, then melt spinning and drying; weaving a fabric using the covering yarn as a warp yarn and a composite yarn as a weft yarn; and washing and drying the fabric; It provides a method of manufacturing an eco-friendly fabric replacing harmful substances, including.

Hereinafter, a method for manufacturing an eco-friendly fabric replacing hazardous substances according to an embodiment of the present invention can be described with reference to FIG. 1 .

First, coffee bean fiber, corn fiber and pineapple fiber are blended to prepare a blended yarn, and then a water-soluble polyurethane fiber is covered in the blended yarn to prepare a covering yarn.

The coffee bean fiber refers to a fiber prepared by synthesizing coffee grounds, a by-product generated while extracting coffee, with a polymer, and the fabric made of coffee bean fiber has a deodorizing function and exhibits quick-drying properties. In addition, coffee bean fibers are eco-friendly because they use coffee residues discarded while extracting coffee as a material, so when discarded, they naturally decay faster than conventional chemical fibers.

The corn fiber refers to a fiber manufactured by processing starch obtained by fermenting a corn by-product to extract poly lactic acid (PLA) and then spinning it. The fabric made of corn fiber is more breathable than polyester, and has quick-drying and flame-retardant properties. Corn fiber is eco-friendly because it uses corn by-products thrown away while harvesting corn as a material, so when discarded, it naturally rots faster than conventional chemical fibers.

The pineapple fiber means a thin fiber extracted from the inside of the outer skin of a pineapple leaf, an evergreen perennial plant of the pineapple family, a monocotyledonous plant. It is suitable for blending together. In addition, the fiber made from pineapple leaves uses about 13 million tons of pineapple processing by-products thrown away at pineapple farms as a material, and when discarded, it is environmentally friendly because it naturally rots faster than conventional chemical fibers.

The polyurethane resin (polyurethane resin) is a material used for manufacturing polyurethane fibers. The polyurethane fiber (polyurethane fiber) is also referred to as an elastic fiber (elastic fiber) refers to a polymer compound containing a polyurethane content of 85% or more. Although the strength of polyurethane fibers is lower than that of other fibers, the fabrics made from them have excellent durability and are used in various fields of textiles, from thin fabrics to heavy clothing with good strength. Polyurethane fiber is the only elastic fiber that stretches like rubber, stretches six times or more, and has good recovery. Polyurethane fibers can produce even very fine threads, so it is possible to produce even microfibers of about 10 dtex (decitex), which is impossible with natural rubber. When mixing with other fibers, sufficient elasticity can be obtained only with a mixing ratio of 5 to 6%. The hygroscopicity is very low, less than 1%, and the specific gravity is 1.0-1.3, which is relatively light. In particular, the water-soluble polyurethane fiber is made by spinning a water-soluble polyurethane resin, and unlike the existing polyurethane resin, it is possible to prevent environmental pollution by replacing the volatile organic solvent with water.

Specifically, the blended yarn may be composed of 30 to 60% by weight of coffee bean fiber, 20 to 40% by weight of corn fiber, and 20 to 40% by weight of pineapple fiber.

In one embodiment, the covering company manufacturing step is a mixture of 5-10% by weight of ginkgo leaf extract, 5-10% by weight of eucalyptus oil, 10-30% by weight of jade powder and 50-80% by weight of a binder after manufacturing the covering company It may be to further include the step of dipping the covering yarn in the mixed solution and then drying.

Next, after mixing with chitosan fiber, seaweed fiber, polyester resin and water-soluble polyurethane resin, melt spinning and drying to prepare a composite yarn.

The chitosan fiber refers to a fiber made by processing a crustacean shell to obtain chitin similar to cellulose and mixing it with a synthetic regenerated fiber, and has excellent waterproof, deodorizing and antibacterial properties. When chitosan fiber is mixed with polyurethane resin and coated on nylon, it has a moisture-permeable and waterproof effect and is used as a fabric material for outdoor use.

The seaweed fiber refers to a biodegradable alginic acid fiber using seaweed as a raw material. Seaweed fiber has superior hygroscopicity compared to cotton, and has antibacterial properties (E. coli, Staphylococcus aureus) and excellent flame retardancy. In addition, the seaweed fiber can be manufactured from seaweed, which is commonly found in the sea, and is eco-friendly because it does not generate pollutants in the production process and is composed of biodegradable fibers that are easy to decompose when discarded.

The polyester resin is a material used for manufacturing polyester fiber, which is a representative synthetic fiber (man-made fiber) compared to natural fiber. It is used for a variety of clothing materials. Polyester fibers have good processability, so they are easy to blend with natural or regenerated fibers, and microfibers can be produced by blending with nylon.

Specifically, the composite yarn may be composed of 10 to 20% by weight of chitosan fiber, 10 to 20% by weight of seaweed fiber, 50 to 70% by weight of a polyester resin, and 5 to 10% by weight of a water-soluble polyurethane resin.

Next, a fabric is woven using the covering yarn as a warp yarn and the composite yarn as a weft yarn.

The weaving may use a conventional weaving process used in the weaving field, and specifically, may be to use a plain weave, a twill weave, and a hand weave.

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. It may be a variable weave, for example, as a variable plain weave, there are a thick 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 mountain type twill weave, and an irregular weave weave, a heavy weave weave, There are harvesters, hwagangs, etc.

In addition, it is possible to manufacture a patterned fabric by blending the above various textures or using yarns of different colors to produce a pattern, 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, a pique weave, a birds-eye weave, a waffle cloth weave, a huekaback weave, a crepe weave, and the like, but is 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 combining colored yarn, plain weave, basket weave, twill, etc. If all are alternately assigned one by one and weaving in plain weave, thin stripes in the warp or weft direction can be made. If you use two contrasting colored yarns for warp and weft, and weave 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 a warp weft yarn, and a non-connected four-point 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 fabric may be subjected to desizing, scouring and bleaching processes performed before the dyeing process after manufacturing the conventional fabric, wherein each process is performed by the method of a conventional desalination, scouring, and bleaching process. can do.

Finally, the fabric is washed and dried to manufacture an eco-friendly fabric replacing harmful substances.

In one embodiment, the washing step is performed by spraying a mixture of 50 to 90% by weight of cypress oil and 10 to 50% by weight of sunflower seed oil on the fabric before washing, and then steaming and drying is repeated 2 to 5 times. It may be to further include the step of

The cypress oil and sunflower seed oil may be added to the fabric to improve the flexibility of the fabric, thereby improving the tactile feel of the fabric produced.

Another aspect of the present application provides an eco-friendly fabric replacing harmful substances manufactured by the above manufacturing method.
