Functional fabric including illite and manufacturing method thereof {Functional fabric incluing illite and manufacturing method of the same}

The present invention relates to a functional fabric, and more particularly, to a fabric containing illite and exhibiting various functions, and a method of manufacturing the same.

Illite is a clay mineral of a porous body that generates far-infrared rays and negative ions to produce antibacterial and deodorizing effects. As it emits negative ions and far-infrared rays that are good for the human body, it promotes metabolism and improves blood circulation. It is known to do. In order to impart such functionality, methods of manufacturing functional products by adding illite powder to products made of various polymer resins have been proposed.

For example, in Korean Patent Publication No. 10-0267351, illite made of fine powder of about 1500 to 3000 mesh is mixed in a polyester chip for fiber manufacturing at a ratio of 1 to 1.4% by weight, and put in a heating stirrer at about 150℃. The master batch manufacturing process in which illite powder adheres to the polyester chip by stirring for about 1 hour, and the master batch is mixed with the polyester chip for fiber in a ratio of 5:5 and put into a rotary dryer. A drying process in which moisture is removed by heating and drying at 150℃ while rotating for ~30 minutes, and a spinning process in which the dried material is put into the melt spinning hopper and melt-spinned while the temperature of the screw spinning machine is about 260℃~270℃. , A method for producing illite synthetic fibers made through a processing process of stretching and twisting spun fibers is disclosed. In addition, Korean Laid-Open Patent Publication No. 1999-0074404 discloses the manufacture of illite fabrics in which illite fibers are mixed with 0.3 to 0.7% by weight of illite powder and used as weft to manufacture illite fabrics. The method is disclosed. In addition, Korean Patent Application Publication No. 2000-0018829 discloses a porous illite powder having a specific surface area of about 13000-14000 ㎠/g is dried at 120°C for 24 hours, mixed with 5-30% by weight of polypropylene chips for fabric manufacturing, and heated. Put in a stirrer, heat agitate, melt and mix, extrude with an extruder, water-cool the extrudate, cut into chips to prepare a master batch, and mix it with polypropylene chips for fibers in a ratio of 8: 2 to 9: 1 to melt. Disclosed is a method for producing illite mixed synthetic fibers in which illite powder is contained in the range of 0.4-3.0% by weight by spinning and stretching the blended product with a spinning nozzle of a spinning machine. In addition, in Korean Patent Publication No. 10-0422478, in the polyester fiber containing ilite containing ferric oxide, ilite purified so that the content of ferric oxide is 0.5% by weight or less is 0.3 of the total weight of the polyester. Disclosed is a polyester fiber, characterized in that the total amount of titanium oxide and the refined ilite is 10% or less of the total weight of the polyester by further containing titanium oxide thereto. In addition, Korean Patent Publication No. 10-0467101 includes a process of pulverizing polyester waste (polyester parsa and PET bottle), adding water and mixing to form chips; Dry the chips of the above process, but when the drying temperature is about 100 to 120°C, add 0.1 to 0.5% by weight of wax based on the weight of polyester and 2 to 4% by weight of illite powder of 1000 to 1700 mesh and rotate until it is about 165 to 175°C. Drying process; Disclosed is a method for manufacturing an artificial fiber containing illite, characterized in that it includes; the process of melting and spinning the chips of the above process into an extruder, winding, seaweeding, stretching, crimping, drying and setting cutting at 130 to 140°C. Has been. In addition, Korean Patent Publication No. 10-0805160 discloses that illite and additives including polymeric resin chips and dispersants are pressed and crushed while passing through a mesh roller, and illite and additives are applied to the surface of the crushed polymeric resin chips. Injecting the mixing and melting tank through the outlet; Through high-speed stirring inside the mixing and melting tank, the polymer resin chip coated with illite, the remaining illite and additives not applied to the polymer resin chip are uniformly mixed, and the surface of the crushed and crushed polymer resin chip is subjected to frictional heat. Forming a mixed resin in which the polymer resin melted by melting and illite and additives are melt-mixed and discharged to an extruder; And extruding, cooling, and cutting while transferring the mixed resin in one direction through a lead screw in an extruder, and contains 40 to 85% by weight of illite and less than 10% by weight of an additive including a dispersant (0 Excluding), a master batch chip containing illite, characterized in that it is contained, is disclosed.

Since the conventional prior art mostly relates to illite-containing fibers, it is necessary to develop a fabric manufacturing technology that reliably exhibits the functionality of illite while using illite-containing fibers as a basic raw material. In addition, Korean Patent Publication No. 10-0805160 discloses a masterbatch chip with an ilite content of 50% by weight in order to maximize the functionality of illite, and short fibers, yarns and fabrics are manufactured from the masterbatch chip. In this case, there is a problem in that the cost of raw materials is remarkably high and the commerciality is greatly deteriorated.
