Description
Technical Field
The invention relates to the field of functional fabrics, in particular to a preparation method of a low-frizzing cotton crepe fabric for inhibiting sweat odor.
Background
Crepe fabrics are a broad class of yarn-dyed products and are popular in the marketplace. The crepe fabric can be produced by a variety of methods, such as using crepe tissue, heavy twist yarns, different shrinkage, elastic or yarn combinations, and special finishing processes. The surface of the cotton crepe fabric should have a finely particulate appearance which is dispersed and of a non-obvious regularity; or various wavy corrugations are formed. The fabric has the main characteristics of plump cloth cover, soft light reflection, smooth and stiff hand feeling, elasticity, soft texture, comfort in wearing and the like. Therefore, the cloth is commonly used as men's and women's shirts, children's wear, skirt materials, night clothes and the like, and can also be used as decorative cloth. Cotton crepe fabrics are one of the main varieties that have been popular in the international market in recent years.
The humidity and heat of the human microenvironment seriously affect the comfort of the garment. Although the pure cotton fabric can absorb a large amount of sweat, when the sweat yield of a person is slightly large, the cotton fiber can expand due to moisture absorption, and cannot timely discharge and emit sweat into the environment, so that the air permeability of the pure cotton fabric is reduced and the pure cotton fabric is stuck to the skin, and cold and wet feeling is caused to the human body. Under the conditions of high temperature, perspiration, moisture or airtight, unpleasant human body odor such as sweat odor and special human body odor such as bromhidrosis and foot odor is often generated after the human body wears the textile, and inconvenience is brought to consumers. The human body odor is mainly organic volatile gas caused by decomposing human skin secretion by bacteria, 3 typical odor molecules of sweat odor are ammonia, acetic acid and isovaleric acid, and the generation of partial human body odor can be prevented by endowing textiles with an antibacterial function, in particular the odor caused by decomposing human body dander or secretion adhered to the textiles by the bacteria which move, which is the odor-resistant concept. However, the deodorizing effect is limited due to the following reasons, and the human body odor is still heavy: firstly, for safety and for the protection against the destructive action of the human skin flora, the national standard prescribes the use of non-leachable antibacterial products, i.e. antibacterial products which cannot migrate to the surface of the human skin, which results in a limited effective working distance of the antibacterial textile, only a few tens of microns. Thus, the antimicrobial fabric is essentially only effective against bacteria that migrate onto it, and not possibly against all bacteria on the skin surface, which is also unsafe. Secondly, bacteria on the skin surface which are not contacted with the textile still generate peculiar smell, such as between the toe heads of the toes. For the part of the human body odor having a large specific gravity which has been generated, it should be eliminated, i.e., deodorized, by a physical or chemical method. The deodorizing ability means that existing odor molecules are eliminated to such an extent that they are not perceived by the human body by physical adsorption or chemical reaction.
Disclosure of Invention
The technical problems to be solved are as follows: the invention aims to provide a low-seam-slip cotton crepe fabric capable of inhibiting sweat odor, which is characterized in that the surface of the cotton crepe fabric is subjected to atomization finishing, small-particle finishing agent is finished on the surface of the fabric by an atomization finishing method, and the finishing agent is finished on the inner side of the fabric to inhibit sweat odor, so that the mechanical properties of the fabric are not affected.
The technical scheme is as follows: a method of making a low seam combing cotton crepe fabric for inhibiting sweat malodour comprising the steps of:
s1, cleaning green persimmons, slicing, drying, ball-milling, crushing, sieving with a 40-100-mesh sieve to obtain persimmon powder, adding the persimmon powder into acetone, stirring to remove pigments and other small molecular compounds, then after the acetone volatilizes, adjusting the water content of the persimmon powder to 50-100%, freeze-drying the persimmon powder with a certain water content, and ball-milling to obtain the persimmon powder with the fineness of 400-500 meshes;
s2, adding the persimmon powder obtained in the step S1 into a methanol solution containing dibenzoyl peroxide, and reacting at a certain temperature to obtain persimmon powder with a surface partially modified by hydroxymethyl;
s3, adding the persimmon powder with the surface partially modified by hydroxymethyl into a protein powder and ceric ammonium nitrate solution, stirring at a certain temperature for reaction, washing after the reaction is finished to remove unreacted components, and drying to constant weight to obtain the protein grafted persimmon powder;
s4, adding the protein grafted persimmon powder into water, performing ultrasonic dispersion, and preparing a protein grafted persimmon powder solution with a certain concentration;
s5, placing the cotton crepe fabric in a sodium carbonate solution to treat the fabric, washing to remove slurry and other impurities on the surface of the fabric, treating the fabric under the conditions of constant temperature and constant humidity, then placing the fabric in an atomizer, uniformly spraying a protein grafted persimmon powder solution on the surface of the cotton crepe fabric, and then drying in an oven to obtain the cotton crepe fabric for inhibiting sweat odor.

Performance test:
deodorizing rate test: the deodorizing rate, i.e. the deodorizing rate of the sample to the odor in a certain period of time, can be used to evaluate the deodorizing ability of the sample to the target gas. During testing, a certain concentration of target gas is filled into the sample container, and after the gas is filled, the sample is quickly placed into the container from the sample port and sealed. After leaving for 2 hours at room temperature, the concentration C of the remaining gas in the container was measured by a detection tube. Meanwhile, filling target gas with the same concentration into a container without any sample, standing for 2h, and testing the concentration C of the residual gas in the container 0 . The deodorizing ratio is calculated by the following formula: y= (C 0 -C)/C 0 X 100%; wherein: y is deodorizing rate; c (C) 0 The gas concentration after 2h of the blank sample container is controlled; c is the residual gas concentration after 2 hours of the sample container with the sample. At least 3 replicates were run and the deodorizing rate was the average of all results.
