Description

Technical Field

[0001] The invention relates to the technical field of fiber fabrics, in particular to a moisture absorbing and perspiration wicking fiber fabric and a preparation method thereof. Background Art

[0002] Moisture wicking fabrics are generally called "moisture wicking and quick-drying fabrics". This fabric generally has a high specific surface area and has many pores or grooves on the surface. At the same time, the cross-section of the fabric fiber is generally a special shape, such as a cross or polygon. The capillary effect can be used to enable the fiber to quickly absorb moisture and sweat from the skin surface and volatilize it through diffusion and transfer to the outer layer; The moisture wicking fabrics currently developed on the market are generally improved in the direction of moisture wicking, but the moisture wicking effect of the prepared fabrics still cannot meet our requirements. At the same time, in actual use, the poor moisture wicking performance can easily lead to bacterial growth on the fabrics, and the antibacterial properties of existing moisture wicking fabrics cannot meet the needs. Therefore, we propose a moisture wicking fiber fabric and a preparation method thereof. Summary of the invention

After polycondensation, the polyester melt is sliced ​​and dried. After the slices are dried, a water-soluble porogen is blended with the polyester slices, and then melted and filtered. After filtering, microporous special-shaped polyester fibers are obtained by spinning through a special-shaped spinneret; S2: using caprolactam as the main raw material to carry out a ring-opening polymerization reaction under high temperature and high pressure conditions to generate a nylon 6 polymer, which is then dried, melted and filtered after drying, and then filtrated through a shaped spinneret to obtain a shaped nylon fiber; S3: PHB is selected as a raw material, and then PHB is dissolved in a solvent to prepare a uniform spinning solution, and the prepared spinning solution is passed through an electrostatic spinning device to form nano-scale fibers under the action of a high-voltage electrostatic field, and then spinning is performed, and drying is performed after the spinning is completed to obtain poly 3-hydroxybutyrate fibers; S4: soaking the prepared microporous shaped polyester fiber, shaped nylon fiber and poly 3-hydroxybutyrate fiber in a bactericide for sterilization and disinfection, and drying after sterilization and disinfection; S5: using poly 3-hydroxybutyrate fiber as the warp and a part of the shaped nylon fiber yarn as the weft to weave a sterilization base fabric, and using microporous shaped polyester fiber yarn as the warp and another part of the shaped nylon fiber yarn as the weft to weave a moisture-absorbing base fabric; S6: injecting the obtained sterilization base fabric and moisture absorption base fabric into a sodium hydroxide solution for ultrasonic cleaning, and then drying, placing them in water for stirring after drying, and then drying: S7: Use suture thread to sew the dried sterilization base fabric and the moisture-absorbing base fabric together to obtain a moisture-absorbing and perspiration-wicking fiber fabric.

[0006] Furthermore, the reaction of polyethylene terephthalate and ethylene glycol in step S1 can be carried out by ester exchange reaction or direct esterification reaction. The ester exchange method includes esterifying dimethyl terephthalate with ethylene glycol to generate bis(hydroxyethyl) terephthalate oligomers, and then polycondensing them under certain temperature and vacuum conditions. The direct esterification method is to directly esterify terephthalic acid with ethylene glycol, and the polycondensation temperature is controlled at 200-300 degrees Celsius.

[0007] Furthermore, the temperature of the ring-opening polymerization reaction in step S2 is controlled at 230-285 degrees Celsius.

[0008] Furthermore, in step S1 and step S2, the cross-sectional shapes of the microporous shaped polyester fiber yarn and the shaped nylon fiber yarn are both Y-shaped.

[0009] Furthermore, in step S3, the solvent can be selected from one of chloroform, dimethylformamide and dimethyl sulfoxide;.

[0010] Furthermore, during the dissolution process in step S3, heating or mechanical stirring may be used to increase the dissolution rate.

[0011] Furthermore, in step S4, the fungicide used for soaking is a quaternary ammonium salt fungicide, and the soaking time is 1-2 hours.

[0012] Furthermore, the ultrasonic cleaning time in step S6 is 10-20 minutes, and the stirring time in water is 15-20 minutes.

[0013] Furthermore, in step S7, the suture thread used for suture is a modified cotton fiber thread obtained by blending bamboo fiber and cotton fiber.

By using a bactericidal base fabric woven from poly 3-hydroxybutyrate fibers and heterosexual nylon fibers, the fabric made from poly 3-hydroxybutyrate fibers can help reduce skin infections because poly 3-hydroxybutyrate fibers have efficient bactericidal and antibacterial properties.
