The present invention relates to a fiber containing a mineral powder and a method of manufacturing the same, and in particular to a powder of a mineral having a functional (crystalline) shape (cleft) and a table (plate shape) alone, or having a functional and crystalline (cleft shape) columnar, pyramid Selectively mix a certain amount of mineral powders, such as phase, rhombohedral, hexahedral, octahedral, and dodecahedral phases, and then selectively mix an inorganic antimicrobial agent with the mixed powder, It relates to a process for producing functional fibers by mixing and to functional fibers produced therefrom.

Reflecting the interest on functional products, the textile field has been manufacturing functional fibers by adding functional minerals to chemical resins for a long time.

As such functional minerals, there are many other types of minerals such as ganbanite, hornblende, rutile, zeolite, zircon, mullite, gemstones, tourmaline, and artificially synthesized natural minerals. These minerals have various functions and effects such as far infrared emission, antibacterial, deodorant, electromagnetic wave blocking, ultraviolet ray blocking, adsorption, hygroscopicity, and anion emission which are beneficial to human body.

Conventionally, the functional fiber is manufactured by adding a certain amount of functional mineral powder to the chemical resin based on the general manufacturing process of the fiber, and then manufacturing the functional fiber by spinning, stretching, flamming, cutting or spinning and weaving. Functional minerals added to the chemical resin in the manufacturing process of the crystal form of the main phase, pyramidal phase, rhombohedral, hexahedral, octahedral, dodecahedral, etc. Abrasion, rollers, guide bodies, etc. were frequently worn, and the surface layer of the yarn produced according to the inherent shape of the mineral was not uniform, so that the surface of the fabric was not smooth. Breakage of the thread frequently occurred.

In other words, mineral fiber is added to produce functional fibers. Due to the irregular crystalline structure of the mineral and the cause of high hardness, the yarn produced has protruding mineral particles on the surface layer, resulting in expensive spinning, stretching, Wear of flammable and spinning process equipment has rendered normal production impossible.

The present invention has been made to solve the above problems of the prior art, the first object of the present invention is far-infrared emission, blood pressure control, pain relief, antibacterial, deodorant, electromagnetic wave blocking, UV protection, absorption, hygroscopic, It has various complex functions and effects such as anion release and is mixed with a certain amount of chemical resin by using one or more kinds of powders of crystalline (cleft) or table (plate) or scaly form and then spun by conventional mixing or spinning method. By manufacturing through post-stretching, flamming, cutting, spinning, the particles of the powder mixed in the yarn is arranged in one direction, so that smooth, smooth and flexible, and has excellent properties compared to conventional fibers.

The second object of the present invention is the mineral powder having the function described in the first object, and the crystal form is tabletop, and the crystal form is in the form of columnar, pyramidal, rhombohedral, or hexahedral, octahedral, dodecahedral, etc. After mixing a certain amount of mineral powder and then mixing with a certain amount of chemical resin and spinning by the usual mixing or spinning method, it is produced by drawing, flamming, cutting, spinning, so that the production process can be performed smoothly and the fiber produced And in addition to the fiber produced under the first object in the effect can be to enhance and complement the function and effect, and to have a soft and excellent touch characteristics compared to the conventional fiber.

The third object of the present invention is to produce a functional fiber as described in the first or second object, by using an electromagnet in the process of fine grinding to remove iron mixed in minerals, While presenting a method for producing a fine mineral powder having a desired particle size by passing it, an antimicrobial activity of the fiber is improved by adding a mixture in which silver (Ag) is supported on zeolite, calcium phosphate, or zirconium phosphate as an inorganic antibacterial agent.
