Description
Technical Field
The invention belongs to the technical field of antibacterial textiles, and particularly relates to a moisture-absorbing antibacterial textile.
Background
Most of the existing school wear fabrics are made of chemical fiber materials, the materials cannot absorb sweat and are easy to sweat, and sweat-wet clothes are easy to attach to a body, so that activities are prevented, and students are influenced to wear. Therefore, a cloth that absorbs moisture well and facilitates student activities is a hot spot for textile research.
A preparation method of terylene and spandex blended moisture-absorbing sweat-releasing high-elastic breathable fish scale fabric as disclosed in CN 111676562A. The method comprises the following steps: respectively soaking polyester yarns in a hydrophilic agent solution and a hydrophobic agent solution, pre-baking, respectively taking the obtained hydrophilic polyester yarns and hydrophobic polyester yarns as surface warps and inner warps, taking the hydrophilic polyester yarns as surface wefts, taking the hydrophobic polyester yarns as inner wefts, weaving the double-layer fabric, simultaneously taking the inner wefts and the surface wefts in the double-layer fabric together as wefts, and taking spandex as warp, and weaving the single-layer fabric. The fabric prepared by the method not only has the effects of moisture absorption and sweat release, but also has the advantages of high elasticity and ventilation. However, the hydrophilic-hydrophobic differential arrangement of the polyester is not obvious for moisture absorption and quick drying enhancement, the polyester is polyester fiber, the polyester fiber has no antibacterial property, and the clothing prepared from the polyester fiber is easy to grow bacteria under the condition of sweat and wet, so that the polyester fiber is unfavorable for student health.
Based on the above, the invention provides the moisture-absorbing and antibacterial textile fabric which has good moisture absorption and perspiration properties, is antibacterial and is suitable for school wear.
Disclosure of Invention
The invention aims to provide a moisture-absorbing antibacterial textile fabric, which solves the problems in the background art.
The aim of the invention can be achieved by the following technical scheme:
a moisture-absorbing antibacterial textile is woven from antibacterial polyester fiber and ramie fiber.
Further, the moisture-absorbing and antibacterial textile fabric has the antibacterial fiber (mass fraction) content of 60-80%, and the ramie fiber content of 20-40%, and the elasticity, antibacterial property and stiffness of the antibacterial fiber, and the air permeability and moisture absorption of the ramie fiber are utilized to obtain the moisture-absorbing and antibacterial textile fabric with good antibacterial property, good moisture absorption and good stiffness
Further, the antibacterial fiber comprises the following steps:
adding the polyester particles and the polymer antibacterial agent into an extruder, extruding and granulating, and extruding to obtain antibacterial polyester particles; then the antibacterial polyester particles are dried to constant weight, and the antibacterial fibers are obtained through melt spinning; wherein the extruder is a double-screw extruder, the extrusion temperature is 160-200 ℃, and the melt spinning temperature is 285-295 ℃.
Further, the mass ratio of the polyester particles to the polymer antibacterial agent is 6-8:1-1.5.
Further, the polymeric antimicrobial agent comprises the steps of:
uniformly mixing the antibacterial oligomer, tetrahydrofuran and epoxy silane coupling agent, reacting for 5-7 hours at the pH value of 9-10 and the temperature of 75-85 ℃, stopping the reaction, and performing rotary evaporation, water washing and drying to obtain the polymer antibacterial agent.
In the reaction, the antibacterial oligomer is taken as a hyperbranched nucleus, the hydroxyl on the surface of the oligomer is utilized to react with the epoxy group in the epoxy silane coupling agent, so that a siloxane chain is introduced into a part of branched chain ends of the branched nucleus, the good low surface activity of the siloxane chain is utilized, the mixing of the polymer antibacterial agent and polyester particles is promoted, meanwhile, the branching characteristic of the antibacterial oligomer is low, the viscosity is low, the molecular chain of the antibacterial oligomer and the polyester molecular chain easily form an interpenetrating network structure, and the processability of the antibacterial fiber is further improved.
Further, the mass ratio of the antibacterial oligomer to the epoxy silane coupling agent is 10:0.3-0.7.
Further, the antimicrobial oligomer is prepared by the steps of:
acetonitrile, chloridion-containing oligomer, hydroxyl-containing quaternary phosphonium salt and sodium hydroxide are uniformly mixed, heated to reflux under the protection of nitrogen, kept for 10-12 hours of reflux reaction, steamed in a rotary way, washed and dried in vacuum to obtain the antibacterial oligomer, wherein the mass ratio of chloridion-containing oligomer to hydroxyl-containing quaternary phosphonium salt is 15-20:12-21.
In the above reaction, the reaction of chlorine in the chlorine-based oligomer and hydroxyl in the hydroxyl-containing quaternary phosphonium salt is utilized, and further, the quaternary phosphonium salt structure is introduced into the branched chain of the oligomer, so that the antibacterial oligomer is obtained, and the excellent antibacterial property of the quaternary phosphonium salt is utilized, so that the excellent antibacterial property is provided.
Further, the chlorine-based oligomer is prepared by the following steps:
uniformly mixing tris (hydroxymethyl) aminomethane, maleic anhydride and ethanol, heating to reflux, keeping the reflux reaction for 8-14h, stopping the reaction, and removing ethanol by rotary evaporation to obtain a product 1, wherein the molar ratio of tris (hydroxymethyl) aminomethane to maleic anhydride is 1:1.01-1.02;
the reaction of amino in the tris and maleic anhydride is utilized to obtain a product 1, wherein one molecule of the product contains three hydroxyl groups and one carboxyl group;
uniformly mixing the product 1 with anhydrous dichloromethane, then fully dripping thionyl chloride, treating tail gas by using sodium hydroxide solution, stirring and reacting for 5-8 hours in an ice water bath, then carrying out suction filtration, washing by using dichloromethane, and carrying out vacuum drying to constant weight to obtain a product 2, wherein the molar ratio of the product 1 to the thionyl chloride is 1:4-5;
