V. INSTRUCTION DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a method for producing a moisture wicking fabric which is subjected to a graft reaction on the surface of a fiber fabric to impart a sweaty property.卞 卞 fabric moisture absorbing line [Prior Art] In the field of fabrics, "the absorbent material has both water absorption and quick-drying or artificial synthetic fibers. It is difficult to make the polypropylene fiber soft, heat-insulating and antibacterial in the synthetic fiber. The potential of high resistance to materials. However, the polypropylene fiber is not good, especially in the high temperature and high humidity. These restrictions make the polypropylene fiber, and the function of the wet perspiration processing technology which is completely non-absorbent increases the function on the market today. Wet wicking woven fabrics include: profiled cross-section fibers, hollow agent coating, and fiber surface modification methods in a blended manner, such as high hydrophilic cotton or wool fibers to impart superior moisture absorption to the fabric. It is a special use in spinning, which is its disadvantage. Hydrophilic agent coating, for example

"Perspiration" refers to the non-hydrophilic texture. In general, both natural fibers have both properties. For example, humans have the functions of light weight, quick drying, soft touch and softness. They are not hydrophilic as high-grade clothes, so the sweat permeability zone or summer is not suitable for the market expansion of clothing and weaving. Because of the polypropylene fiber, it is not necessary to use the suction property to make it more widely used. The material can be made by the following techniques: mechanical porous fiber, multi-layer fabric, hydrophilic. Generally, the most commonly used method of textiles, No. 5, 3 1 2, 6 6 7 , discloses that it will be blended or interlaced with polyester fibers, and then shaped cross-section fibers and hollow microporous spun yarns, but the production cost Too high as revealed by 11 " 0 93 1 6782

1295330 V. DESCRIPTION OF THE INVENTION (2) The hydrophilic agent is applied to the fiber by post-treatment to further impart hygroscopicity to the fiber. The disadvantage is that it is not resistant to washing, and the hydrophilic agent is easily peeled off. The surface modification of the fiber is disclosed in, for example, U.S. Patent Nos. 5,354,81, and 4,808,188, the chemical composition of the fiber is changed by chemical reaction during the dyeing and finishing stage, and Producing a hydrophilic functional group to make the fiber hydrophilic. The disadvantage is that the production speed is slow, and a large amount of waste water is easily generated in the production process. [Invention] The object of the present invention is to provide a fabric for absorbing moisture wicking fabric. The invention provides a moisture wicking fabric, in particular polypropylene fiber woven fabric, to achieve the above object of the present invention. The invention has the advantages of moisture absorption and wicking, and the weaving/twisting step comprises pre-forming the surface of the hydrophobic fiber fabric. Treatment*: forming an over-emulsified product; in a solution containing polyalcohol, tert-unsaturated (d), and an alcohol, a natural glycan, and a sulphate, which are activated by oxidation; Hydrophobicity: reaction formation copolymerization ^ ^ ^ ^ ^ ^ ^ Orbital water fiber fabric surface in solution and go

The grafting reaction is carried out to form a covalent bond to obtain moisture wicking (IV) The method for producing a moisture wicking fabric of the present invention, which has a sputum " a good agent (hydrophilic substance) and fiber Washable for covalent bonding, so washable

1295330 V. INSTRUCTIONS (3) 2. The object to be treated may be a high water-repellent fabric such as 1 〇 〇% polypropylene fiber or polypropylene blend fiber, polyester fiber and polyamide fiber. The hydrophilic substance is grafted on the surface of the fiber to impart hydrophilicity to the surface of the fiber to improve the permeation of the fiber without damaging the original soft touch of the fiber, and the inner part of the fiber remains hydrophobic, so that the fabric has a fast drying property. This moisture wicking and dry function is more valuable for polypropylene that is strongly grown due to its antibacterial properties and light weight. No need to change the original process equipment, raw

Third, it can be implemented when the fabric is shaped, the production speed is fast, the cost is low, and the waste water is small. [Embodiment] The method for producing a moisture wicking fabric of the present invention is carried out by grafting a surface of a main fiber. Referring to the flow chart 1 shown in the figure, the following is not intended to illustrate the method of the present invention.
