Hereinafter, the present invention will be described in detail.

The present invention provides a process for producing an environmentally friendly composite yarn comprising the steps of producing a composite yarn using ramie fiber, metallic yarn and PET fiber.

The laminated yarn is a vegetable material which is harmless to human body and has a natural material texture and excellent in insect repellency, antifouling property, deodorizing property and the like, and has remarkably excellent air permeability as compared with other fibers. The laminating yarn is produced by removing the outer shell and the air-hole of the harvested mother lily, dipping the laminating fiber into water several times, drying the laminating fiber, and twisting the produced laminating fiber to a certain thickness and length Can be used.

In addition, since the quality of the laminated yarn is not uniform due to the uneven quality such as strength, elongation, and fiber thickness, mechanical properties may be deteriorated. In order to compensate for this, the laminated yarn is formed by spinning a laminated yarn and a polyester yarn The laminated yarn can be utilized. The laminated yarn used as the laminated yarn is preferably made of laminated yarn formed by spinning 10 to 90% of laminated yarn and 10 to 90% of polyester yarn, .

The metal yarn serves to maintain mechanical strength in the composite yarn, to block ultraviolet rays by reflecting light, to impart flame retardancy, and to be made of a metal such as gold (Au), silver (Ag) The material can be used without limitation as long as it is manufactured by mechanical processing such as melt extraction method, cutting method or drawing method. In particular, the metal yarn is preferably made of a material having high corrosion resistance, and stainless steel yarn made of a stainless steel alloy can be preferably used. Alternatively, a metal yarn made of silver (Ag) having an excellent antimicrobial and anti-acupuncture effect, generating anion to stabilize the mind and body, and inducing activity of energy can be used.

The metal yarn may be formed with irregularities along the length direction at an interval of 0.5 to 20 mm. The metal yarn has a good elasticity due to the irregular shape. The elasticity of the metal yarn makes it easy to process the fabric, , Can be made freely of any type of fabric, and the fabric produced is of a soft texture. In addition, the metal yarn has the property of being easily entangled with various types of fibers formed by the irregularities, and the frictional force is increased and the stability is excellent.

When the diameter of the metal yarn is less than 0.01 mm, the diameter of the metal yarn is small and the tensile force is weak. When the thickness exceeds 1 mm, the diameter of the metal yarn is large, The metal yarn having a diameter of 0.05 to 0.5 mm can be used.

The polyester (PET) yarn is a synthetic fiber obtained by spinning a polyester which is a polymer of terephthalic acid and ethylene glycol. It is a non-toxic material minimizing environmental harm, and has excellent transparency, excellent stretchability, It can be used without restriction as long as it has excellent wrinkle recovery and low hygroscopicity.

Preferably, the polyester yarn is preferably an LM yarn having a low melting point, and the woven fabric having the LM yarn is woven together with the metal yarn and the laminated yarn, , The LM yarn is melted and strongly bonded to the metal yarn and the laminated yarn to form a fabric having excellent bonding force. Further, when the LM yarn is cured after the heat treatment, the LM yarn becomes stiff and gives rigidity to the fabric, so that a fabric having excellent drape characteristics can be formed.

Therefore, even if the conventional method of coating a coating agent to impart drape to a fabric is not used, when the fabric is manufactured by weaving the LM yarn as described above and then heat-treating the fabric under specific conditions, It is possible to form an excellent fabric without causing any deformation due to temperature and humidity.

On the other hand, the fabric can be produced by using ramie yarn, metal yarn and polyester yarn as warp and weft yarns, respectively, and weaving them in a predetermined ratio. In particular, To 1:10, and weaving the laminated yarn, metal yarn and polyester yarn.

The weaving method can be carried out using various conventional methods. However, it is possible to manufacture a fabric having a jacquard pattern by woven using a jacquard loom, or to fabricate a fabric having a jacquard pattern and use the fabric as a blind fabric.

Alternatively, the fabric can be produced by spinning a metal yarn, a laminated yarn, and a polyester yarn by using various conventional spinning yarn manufacturing methods to produce a composite yarn, and using the thus produced composite yarn as warp and weft yarns, Can be manufactured.

For example, the metal yarn, the laminated yarn and the polyester yarn may be wound together into a single yarn to produce a composite yarn, which may be woven to form a fabric.

Specifically, a metal yarn 100, a laminated yarn 200 and a polyester yarn 300 are arranged and wound in the same manner as a single yarn to form a composite yarn 10 having a cross section and a side surface as shown in FIG. 1 ) Can be formed.

As another example, a composite spun yarn is manufactured by introducing a wrapping technique, and the composite spun yarn is woven by using it as warp and weft yarns to produce a fabric.

Specifically, the composite yarn may be a core of a metal yarn to cover the periphery of one or a plurality of metal yarn strands with a polyester yarn in a coil shape to form a polyester yarn layer, A composite yarn having a triple structure of a metal yarn core layer 100, a polyester fiber layer 200, and a laminated fiber layer 300 as shown in Fig. 2 (see Fig. 2) by covering the laminated yarn in a coil- 10) can be formed. Further, the composite yarn 10 having a triple structure of the metal yarn core layer 100 ', the polyester fiber layer 200 and the laminated fiber layer 300 having unevenness as shown in FIG. 3 can be formed, Can be used to weave textiles.

The fabric may also include 10 to 40% mixed lami yarns, 5 to 20% mixed metal yarns and 35 to 85% mixed polyester yarns, preferably 30 to 45% mixed laminates It is possible to manufacture a fabric having excellent properties such as human affinity, longevity, antifouling property and deodorizing property including yarn.

According to the method of manufacturing a fabric for blinds according to the present invention as described above, it is possible to produce a woven fabric for blinds by using a laminated yarn, a metal yarn, and a polyester yarn, which are eco-friendly vegetable materials, A fabric having an inferior dimensional stability, flexibility, gloss, shrinkage and fusing property and excellent mechanical strength and dyeability can be produced.

In particular, the fabric may be fabricated by weaving the composite yarn through a conventional weaving method commonly used for the manufacture of textile fabrics, but preferably the fabric fabric is a dobby fabric The fabric can easily block the light coming from the outside while keeping the decorative property such as a curtain or a blind paper while allowing the light entering through the window of the room to be easily reflected And the heat exchange with the outside can be effectively blocked.

The blind fabric may be woven such that the warp density is 80 to 150 yarns / inch and the weft density is 30 to 100 yarns / inch, and preferably the warp density is 100 Inch / inch and a weft density of 50 bands / inch.

The fabrics manufactured by weaving the composite yarn with the woven fabric do not need to be coated with the conventional fabric for introducing ultraviolet rays, flame retardancy, antibacterial properties, etc., and thus the manufacturing process is also environmentally friendly.

The woven fabric may be a woven fabric after being woven and heat treated, and the woven fabric treated by such a subsequent heat treatment process exhibits excellent dimensional stability and smoothness of the fabric surface. Further, the polyester yarn contained in the fabric is melted by the heat treatment to form stronger bonding force between the polyester yarn and the laminated yarn, and stiffness is formed after the polyester yarn is cured to have excellent drape property . The heat treatment may be performed at a temperature of 150 to 200 ° C, and ironing may be used.

The fabric may be dyed in various ways to provide a desired pattern and color.

Also, in the present invention, there is provided a woven fabric having a function of a dark coat formed by weaving a yarn such as an LM yarn having a dark coat property by using a composite yarn including ramie yarn, metal yarn and polyester yarn as a ramp .
