Description

Soft water-absorbing fabric and application thereof
Technical Field
The invention belongs to the field of textiles, and particularly relates to a soft water-absorbing fabric and application thereof.
Background
With the continuous improvement of living standard, the requirements of people on the quality of clothes are higher and higher. The garment is made by cutting the fabric, so that the characteristics of the fabric determine the quality of the garment to a great extent. Soft and comfortable is the most intuitive and original evaluation and is the primary consideration of all properties. As for natural fiber fabrics, especially pure cotton fabrics, the natural fiber fabrics are favored by consumers due to good water absorption. However, the pure cotton fabric can be close to the skin after absorbing moisture, so that consumers feel uncomfortable. The conventional chemical fiber fabric has poor water absorption, and sweat stains can not be effectively discharged in time when people wear the fabric to generate stuffy feeling, so that the wearing comfort is directly influenced. In addition, in the wearing process, microorganisms generally exist on the fabric of the clothes, and the microorganisms can rapidly propagate under the condition of proper temperature and humidity, so that the fabric stained with sweat and human body secretion generates stink, cortex aging is caused, and various skin diseases are even caused, so that the safety and the antibacterial property of the fabric are also important while the wearing comfort is ensured.
For example, chinese patent document CN103422340A discloses a production and finishing process of a water-absorbent soft fabric, which uses a finishing agent containing hydrogen peroxide, 2D resin, water-soluble polyurethane and other components to process a blended fabric of polyester fibers and cotton fibers to obtain a soft water-absorbent fabric. For another example, chinese patent document CN108301096A discloses a process for producing a soft fabric with high water absorption, which comprises the steps of preparing a woven fabric from yarns blended with polyester fibers and cotton fibers, and dyeing and finishing the woven fabric, wherein the polyester fibers have hydrophilic functional groups in the molecules, so as to obtain a permanent soft fabric with high water absorption and washing resistance. But none of these fabrics have antimicrobial properties.
For another example, chinese patent document CN101469511A discloses a super absorbent soft antibacterial textile, wherein a hydrophilic and soft polyester compound and an antibacterial compound are attached to the surface of a fiber by using a binder to obtain the super absorbent soft antibacterial textile, but the antibacterial property obtained by the method is only against staphylococcus aureus, i.e., gram-positive bacteria, and the used binder exerts a certain influence on the hand feeling.
Disclosure of Invention
The invention aims to provide the fabric which is simple in production method, safe and environment-friendly, and has the advantages of antibiosis, softness, water absorption and high water washing resistance, and the application thereof.
The technical solution of the invention is as follows:
the soft water-absorbing fabric comprises the following components in parts by weight:
the component 1 at least comprises carbohydrate, anthraquinone compound and amino acid compound;
the component 2 is one or more of benzene derivatives, phenol derivatives, pyrrolidones, amines, amides, ethers, esters and alcohol compounds.
The fabric integrates antibacterial property, softness and water absorption, has the characteristics of natural degradability, excellent washability and the like, and can be applied to manufacturing clothes, bedding, towels or socks and the like.
Detailed Description
The soft water-absorbing fabric comprises the following components in parts by weight:
the component 1 at least comprises carbohydrate, anthraquinone compound and amino acid compound;
the component 2 is one or more of benzene derivatives, phenol derivatives, pyrrolidones, amines, amides, ethers, esters and alcohol compounds.
The carbohydrate in the invention can be galactose, mannose, glucose, fructose, arabinose, sucrose, lactose, trehalose, xylose or rhamnose, and can also be polysaccharide composed of the above components, etc. Carbohydrate, especially polysaccharides, has a large amount of hydrophilic hydroxyl groups, and the hydroxyl groups, carboxyl groups and other polar groups of the carbohydrate can form hydrogen bonds with water molecules to combine a large amount of water, and meanwhile, molecular chains of the carbohydrate can be interwoven into a net shape and combined with the hydrogen bonds of water, so that the carbohydrate, especially the polysaccharides, can play a strong role in absorbing water and preserving moisture. The carbohydrate content can be adjusted as desired. In the present invention, if the carbohydrate content is less than 1.8% by weight, the water absorption tends to decrease; on the other hand, if the content of the carbohydrate is more than 3.0% by weight, the dispersibility tends to be poor due to the physicochemical properties of high viscosity. Therefore, the content of the carbohydrate in the present invention is preferably 1.8 to 3.0% by weight.
The amino acids referred to in the present invention may be threonine, valine, isoleucine, leucine, phenylalanine, lysine, arginine, aspartic acid, glutamic acid, etc. The amino acid is used as an amphoteric surfactant, can show anionic or cationic properties along with the change of pH value, has mild performance and strong affinity to fibers, and can reduce the frictional resistance between fiber tissues or between fibers and a human body, thereby endowing the fabric with soft hand feeling. The content of the amino acid compound can be adjusted as required. When the content of the amino acids is less than 0.6 percent by weight, the softness of the fabric may not meet the requirement; when the content exceeds 1.0% by weight, the fiber cohesion is reduced and the yarn strength tends to be lowered. Therefore, the content of the amino acid compound in the present invention is preferably 0.6 to 1.0% by weight.
The anthraquinone compound in the invention can be anthraphenol, oxidized anthraphenol, anthrone, dianthraquinone or dianthranone, and can also be glycosides of the compounds. The anthraquinone compounds have antibacterial effect by inhibiting oxidation and dehydrogenation of thallus saccharide and metabolism intermediate product, and inhibiting synthesis of protein and nucleic acid. The content of the anthraquinone compound can be adjusted according to the requirement. If the content of the anthraquinone compound is less than 0.9 wt%, the enzyme system activity of the microorganism may not be effectively inhibited, so that the protein is coagulated, the activity of cell synthase is destroyed, and the microorganism such as bacteria cannot be poisoned; if the content of the anthraquinone compound is more than 3.0 wt%, the antibacterial activity to be exhibited by the active ingredient is already more than 99%, and the material cost tends to increase. Therefore, in view of the antibacterial effect, the content of the anthraquinone-based compound in the present invention is preferably 0.9 to 3.0% by weight.
The surface and the inside of the fiber forming the fabric also contain a component 2, and the component 2 is one or more of benzene derivatives, phenol derivatives, pyrrolidones, amines, amides, ethers, esters and alcohols. The solvents can swell the fibers, weaken the force among fiber macromolecules, facilitate the diffusion of the component 1 to the interior of the fibers and fix the component in the interior of the fibers, and thus effectively improve the washing fastness. Wherein the benzene derivative may be biphenyl, diphenyl ether, chlorobenzene, p-dichlorobenzene, perchlorobenzene, acetophenone, diphenyl ether, etc., the phenol derivative may be phenol, o-phenylphenol, p-phenylphenol, o-phenylphenol sodium salt, monochloro-phenylphenol, etc., the pyrrolidone may be N-octyl pyrrolidone, N-methyl pyrrolidone, N-cyclop ethyl pyrrolidone, etc., the amine may be phthalic diamide, bisdodecenyl dimethylammonium bromide, bisdodecyl dimethylammonium bromide, etc., the amide may be N, N-dibutylformamide, N-diethylbenzamide, N-dimethyloctanoamide, N-dimethyldecanoamide, N-methylphthalimide, N-ethylphthalimide, N-isopropylphthalimide, etc, N-N-butylphthalimide, etc., wherein the ether may be polyoxyethylene ether, the ester may be methylphenyl phthalate, ethylene phthalate, methyl benzoate, dimethyl benzoate, butyl benzoate, phenyl benzoate, methyl 2-hydroxy-3-methylbenzoate, methyl salicylate, methyl 4-methylsalicylate, and the alcohol may be benzyl alcohol, phenylpropyl alcohol, diethylene glycol, etc.
In the invention, the component 2 is preferably alkyl dimethyl benzyl ammonium chloride, and the chemical structure of the alkyl dimethyl benzyl ammonium chloride is as follows:
Figure 37681DEST_PATH_IMAGE001
the component 2 can promote the component 1 to diffuse into the inside of the fiber and to be fixed inside the fiber, thereby effectively improving the washability. Meanwhile, the alkyl dimethyl benzyl ammonium chloride has solubilizing capability, can increase the solubility of the component 1, enables the component 1 to easily form a high-concentration layer on the surface of the fiber, and is more favorable for permeation and diffusion of the component 1 according to high and low concentration difference.
The fabric of the invention is woven fabric, knitted fabric or non-woven fabric which is formed by singly or blending natural fibers such as cotton, wool, silk and hemp, regenerated fibers such as viscose, cuprammonium, acetate and the like, or synthetic fibers such as terylene, chinlon, acrylon, spandex, vinylon and the like.
The processing method of the present invention is not particularly limited, and the treatment in a bath may be carried out or the padding may be carried out. The specific processing conditions in the bath are as follows: heat treatment is carried out for 30-60 minutes under the condition of 40 ℃, and then drying is carried out under the condition of 110-130 ℃. The padding processing specific conditions are as follows: after one-dipping one-rolling or two-dipping two-rolling, heat treatment is carried out for 2-5 minutes at the temperature of 110-130 ℃. Among them, the padding process is preferable, and the padding process of one pad and one dip is more preferable.
