Description
Technical Field
The invention relates to the technical field of blended fabrics, in particular to a stretch-proof and fracture-resistant blended fabric.
Background
With the improvement of living standard, people put more and more demands on the functions of fabrics, when people go out to travel, people often suffer from mosquito bites, but the travelling burden is increased by carrying mosquito repellent liquid, insecticide and other medicaments with people; the quantity of exercise is great in the journey, and the fabric is required to have certain moisture absorption and air permeability, and is comfortable, but the fabric is too strong in moisture absorption, so that clothes cannot be dried in time, bacteria are easy to breed after the wet clothes are worn for a long time, people feel uncomfortable, and cold is caused.
The viscose is a cellulose fiber obtained by taking natural fiber as a raw material and adopting a wet spinning technology and a series of treatments, has strong hygroscopicity and air permeability, smooth hand feeling, smoothness and softness, low price and comfortable wearing, but has the defects of wear resistance, easy fuzzing, poor elasticity and easy fracture, thereby limiting the application of the viscose, and the strong water absorbability of the viscose easily causes bacteria and corrosion to be more easily bred in the viscose, and influences wearing feeling.
Therefore, a stretch-proof fracture-resistant blended fabric with proper hygroscopicity and mosquito-proof and antibacterial properties and a preparation method thereof are needed to solve the problems. Disclosure of Invention
In order to solve the technical problems, the invention provides the following technical scheme: stretch-proof fracture-resistant blended fabric and preparation method thereof.
The stretch-proof fracture-resistant blended fabric comprises the following raw materials in parts by weight: 80-100 parts of modified viscose fiber, 80-100 parts of modified combed cotton fiber and 100-120 parts of polyurethane fiber.
The modified viscose fiber contains a large number of cationic groups such as guanidine groups and amino groups, and the modified combed cotton fiber contains a large number of anionic groups such as carboxymethyl groups and hydroxyl groups, so that the modified combed cotton fiber has stronger adsorption force on the modified viscose fiber; the modified viscose fiber and the modified combed cotton fiber are made into the blended yarn through the Siro spinning technology, the modified viscose fiber and the modified combed cotton fiber are bonded together through the electrostatic self-assembly effect, and the tensile strength and the breaking elongation of the obtained blended yarn are obviously improved.
Further, the modified viscose fiber comprises the following raw materials in parts by weight: the anti-mosquito liquid comprises, by weight, 20-30 parts of a modified anti-mosquito liquid, 30-50 parts of a carrier and 80-120 parts of a viscose fiber spinning liquid.
Further, the modified mosquito-repellent liquid comprises the following raw materials in parts by weight: the weight portions of the components are 60-70 portions of hydrazine ethyl chitosan oligosaccharide, 20-30 portions of glycerin, 15-20 portions of peppermint extract, 20-25 portions of pyrethrin, 8-12 portions of deet, 10-14 portions of emulsifying agent, 30-35 portions of urea and 25-35 portions of dimethyl sulfate. The emulsifier is ammonium dodecyl sulfate.
The main components of the modified mosquito-proof liquid are natural components, so that the modified mosquito-proof liquid is safe and nontoxic and has good mosquito-proof effect; because the volatile components of the mint extract, the pyrethrin, the deet and the like are strong, the long-acting mosquito-repellent effect is difficult to realize by directly adding the mint extract, the pyrethrin, the deet and the like into the fabric; the invention uses emulsifying agent to emulsify hydrazine ethyl chitosan oligosaccharide, glycerin, peppermint extracting solution, pyrethrin and mosquito-repellent amine at high speed to obtain emulsion, then uses urea and dimethyl sulfate to react to generate methylated urea, and the methylated urea reacts with nucleophilic substitution of the emulsion to obtain guanylated emulsion, namely modified mosquito-repellent liquid;
firstly, vinyl triethoxysilane is hydrolyzed and condensed in nitric acid solution to form vinyl oligomeric silsesquioxane; then, zirconium chloride and 2-amino terephthalic acid are subjected to solvothermal reaction to generate a metal organic frame, the metal organic frame is modified by methacrylic anhydride, and vinyl is successfully modified on the surface of the metal organic frame; copolymerizing vinyl oligomeric silsesquioxane and a vinyl metal organic frame under the action of azodiisobutyronitrile, bonding the vinyl oligomeric silsesquioxane and the vinyl metal organic frame together through covalent bonds, and finally modifying part of amino on the surface of the vinyl oligomeric silsesquioxane and the vinyl metal organic frame through hydrazine hydrate and ethylenediamine to obtain a carrier;
the oligomeric silsesquioxane contains Si-O-Si bonds, has strong mechanical properties, low surface energy and certain hydrophobicity; the metal organic framework is a nano porous material formed by metal ions and ion clusters, has larger specific surface area, but has insufficient mechanical properties, is unstable in a humid environment, and has limited application; the carrier prepared by the invention combines certain hydrophobicity of the oligomeric silsesquioxane and larger specific surface area of the metal organic frame, and is modified with amino groups on the surface and mixed with viscose spinning solution to prepare modified viscose, so that the carrier can reduce the water absorption of the modified viscose; because the viscose contains a large number of hydroxyl groups, the agglomeration phenomenon is easy to occur when the carrier is directly mixed into the viscose, the compatibility of the carrier and the viscose spinning solution is poor, and the mechanical property of the viscose is greatly influenced; the amino group is modified on the carrier, so that on one hand, the dispersibility of the carrier in the viscose spinning solution can be improved, on the other hand, the amino group on the carrier can react with the hydroxyl group in the viscose spinning solution, the compatibility of the carrier in the viscose spinning solution is enhanced, and the mechanical property of Gao Gaixing viscose is improved; meanwhile, the amino is taken as a cation and can react with hydroxyl in the modified combed cotton fiber, so that the modified combed cotton fiber and the modified viscose fiber have stronger interface binding force; the mechanical properties of the prepared blend fiber are greatly improved by utilizing the synergistic effect of the modified combed cotton fiber and the modified viscose fiber.
The invention uses low pressure condition to remove air in the carrier of viscose fiber as far as possible, when the pressure is restored to normal pressure, the anti-mosquito liquid is pressed into the carrier on the viscose fiber by the atmospheric pressure to obtain the modified viscose fiber; the low-pressure environment can increase the load capacity of the modified mosquito-repellent liquid in the carrier as much as possible;
the modified mosquito-repellent liquid is a guanylated mosquito-repellent liquid, and the guanidine belt has positive charges, so that the modified mosquito-repellent liquid prepared by introducing the guanylated mosquito-repellent liquid into the mosquito-repellent liquid has a strong sterilization and bacteriostasis capability, and has a good mosquito-repellent function and a strong sterilization capability; electrostatic self-assembly occurs between the guanidine groups and the modified combed cotton, and the modified mosquito-repellent liquid can be effectively fixed in the blend fiber and is not easy to volatilize and run off, so that the mosquito-repellent effect of the blend fabric is longer and longer;
the hydrazine ethyl chitosan oligosaccharide and the mint extracting solution which are specially added into the modified anti-mosquito liquid have certain antibacterial and bacteriostatic effects, and fresh aroma emitted by the mint extracting solution can inhibit the generation of mildewing and peculiar smell of the blended fabric, keep the blended fabric to continuously emit fresh taste, and are pleasant in mood;
further, the carrier comprises the following raw material components: the anti-aging agent comprises, by weight, 70-80 parts of vinyl triethoxysilane, 40-50 parts of nitric acid, 10-20 parts of dichloromethane, 25-35 parts of zirconium chloride, 18-24 parts of methacrylic anhydride, 8-10 parts of triethylamine, 8-10 parts of chloroform, 18-24 parts of azobisisobutyronitrile, 20-26 parts of zinc acetate, 10-20 parts of hydrazine hydrate and 10-16 parts of ethylenediamine.
Further, the modified combed cotton fiber comprises the following raw materials in parts by weight: 80-100 parts of combed cotton fiber, 8-10 parts of sodium hydroxide and 10-16 parts of ammonium chloroacetate.

antibacterial rate test: evaluation of antimicrobial Properties of textiles section 3, see GB/T20944.3-2008: the oscillation method tests the antibacterial rate of staphylococcus aureus in the blended fabric sample.
As shown in the table data, the blended fabric prepared in the examples 1-3 has strong mechanical properties, the tensile strength is above 55MPa, and the elongation at break is greatly improved compared with that of common viscose fibers; the antibacterial rate to staphylococcus aureus is above 95%, and the antibacterial agent has stronger antibacterial capability.
Example 4
The difference with example 3 is that the guanidyl modification is not carried out on the anti-mosquito liquid, the anti-mosquito antibacterial effect of the prepared blended fabric is obviously reduced due to the lack of guanidyl, and meanwhile, the bonding force between the modified viscose fiber and the modified combed cotton fiber is greatly reduced, so that the mechanical property of the prepared blended fiber is reduced.
Example 5
The difference from example 3 is that the carrier is not modified by amino groups, the prepared carrier is agglomerated in the viscose spinning solution, the interfacial binding force between the modified viscose and the modified combed cotton fiber is reduced, and the mechanical property of the prepared modified viscose is obviously insufficient.
Example 6
The difference from example 3 is that the modified anti-mosquito liquid is directly mixed into the viscose spinning liquid for adding the carrier, the proportion of the viscose spinning liquid in the viscose is reduced due to the addition of the modified anti-mosquito liquid, and the mechanical property of the prepared viscose is seriously insufficient.
Example 7
The difference from example 3 is that the combed cotton fiber is not modified, and a large amount of anions are not modified on the combed cotton fiber, so that the interface binding force between the combed cotton fiber and the modified viscose fiber is not enough, the mechanical property of the blend fiber is greatly influenced, the loss of antibacterial substances is serious, and the blended fabric is reduced.
Comparative example:
the blended fabric obtained by blending the common viscose fibers, the common combed cotton fibers and the polyurethane fibers has poor interfacial bonding force among the fibers and insufficient antibacterial performance.
From the above data and experiments we can conclude that: firstly preparing guanidine anti-mosquito liquid, compounding oligomeric silsesquioxane and a metal organic framework, modifying amino to obtain a carrier, and mixing the carrier into viscose spinning liquid to prepare modified viscose; the modified viscose fiber contains a large number of cationic groups such as guanidine groups and amino groups, and the modified combed cotton fiber contains a large number of anionic groups such as carboxymethyl groups and hydroxyl groups, so that the modified combed cotton fiber has stronger adsorption force on the modified viscose fiber; the modified viscose fiber and the modified combed cotton fiber are made into the blended yarn through the siro spinning technology, the modified viscose fiber and the modified combed cotton fiber are bonded together through the electrostatic self-assembly effect, and the prepared blended yarn has good stretch-proof and fracture-resistant performance and good antibacterial and antibacterial effects.
