Description
Technical Field
The invention relates to the field of functional fabrics, in particular to a preparation method of a low combing crack crepe fabric for inhibiting sweat odor.
Background
Crepe fabrics are one of the broad categories of yarn-dyed products and are popular in the market. Crepe fabrics are produced by a number of methods, such as by using crepe weave, hard twist yarns, different shrinkage, elasticity or combinations of yarns, and special post-finishing processes. The surface of the cotton crepe fabric should have a dispersed and unnoticeable fine granular appearance; or forming various wave-shaped wrinkles. The fabric is characterized by plump cloth cover, soft reflection, smooth and stiff hand feeling, high elasticity, soft texture, comfortable wearing and the like. Therefore, it is often used as shirt, garment, skirt, pajamas, etc. for men and women, and also as decorative cloth. Cotton crepe fabrics are one of the main varieties popular in the international market in recent years.
The damp heat in the microenvironment of the human body seriously affects the comfort of wearing. Although the pure cotton fabric can absorb a large amount of sweat, when the sweat amount of a person is slightly large, the cotton fiber can absorb moisture and expand, and cannot discharge the sweat in time and diffuse the sweat into the environment, so that the air permeability of the pure cotton fabric is reduced, and the pure cotton fabric is stuck on the skin, and causes a cold and wet feeling to the human body. Under the conditions of high temperature, sweating, humidity or sealing, unpleasant human body peculiar smell such as sweat odor and special human body peculiar smell such as bromhidrosis and foot odor is often generated after a human body wears textiles, so that inconvenience is brought to consumers. The odor of human body is mainly due to organic volatile gas caused by bacteria decomposing secretion of human skin, 3 typical odor molecules of sweat odor are ammonia gas, acetic acid and isovaleric acid, and the odor of human body can be prevented from being generated partially by endowing the textile with an antibacterial function, particularly the odor caused by decomposing human body dander or secretion adhered to the textile by the bacteria which are born, so that the concept of odor prevention is realized. However, the deodorizing effect is limited due to the following reasons, and the human body odor is still heavy: first, due to safety and destructive concerns about preventing human skin flora, national standards prescribe the use of non-leaching antimicrobial products, i.e. antimicrobial products that cannot migrate to the surface of human skin, which results in antimicrobial textiles with a limited effective working distance of only a few tens of microns. Therefore, the antibacterial fabric is effective only on bacteria colonized thereon, and is unlikely to be effective on all bacteria on the skin surface, which is also unsafe. Secondly, bacteria on the skin surface which is not contacted with the textile can still generate peculiar smell, such as between toes of the feet. The part of the human body odor with large specific gravity which is generated already should be eliminated by physical or chemical methods, namely, deodorization. The deodorizing property means that existing odor molecules are eliminated to such an extent that the odor molecules cannot be sensed by a human body by means of physical adsorption or chemical reaction.
Disclosure of Invention
The technical problem to be solved is as follows: the invention aims to provide a low combing crack cotton crepe fabric for inhibiting sweat odor, which is characterized in that the surface of the cotton crepe fabric is treated by atomization finishing, a small-particle finishing agent is treated on the surface of the fabric by the atomization finishing method, and the finishing agent on the inner side of the fabric is treated to inhibit the sweat odor without affecting the mechanical property of the fabric.
The technical scheme is as follows: a method of making a low combing crack crepe fabric that inhibits sweat odor comprising the steps of:
s1, cleaning green persimmons, slicing and drying, performing ball milling and crushing, and screening by 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 is volatilized, adjusting the water content of the persimmon powder to 50-100%, performing freeze drying on the persimmon powder with certain water content, and performing ball milling treatment to obtain the persimmon powder with the fineness of 400-plus-500 meshes;

s3, adding protein powder and a ceric ammonium nitrate solution into the persimmon powder with the surface part modified by hydroxymethyl, stirring at a certain temperature for reaction, washing after the reaction is finished to remove unreacted components, and drying to constant weight to obtain 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-creped 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 the protein grafted persimmon powder solution on the surface of the cotton-creped fabric, and then drying in an oven to obtain the cotton-creped fabric capable of inhibiting sweat odor.

and (3) deodorizing rate testing: the odor elimination rate, namely the odor elimination rate of the sample in a certain time, can be used for evaluating the elimination capability of the sample on the target gas. During testing, the sample container is filled with target gas with certain concentration, and after the sample container is filled with the target gas, the sample is quickly put into the container from the sample opening and is sealed. After standing at room temperature for 2h, the concentration C of the residual gas in the container was measured with a detector tube. Meanwhile, filling the container without any sample with target gas with the same concentration, standing for 2h, and testing the concentration C of the residual gas in the container0. The odor eliminating rate is calculated by the formula: y ═ C0-C)/C0X is 100%; in the formula: y is the deodorization rate; c0The gas concentration of the blank sample container after 2 hours is compared; and C is the residual gas concentration of the sample container with the sample after 2 h. At least 3 replicates were run and the odor elimination rate was the average of all results.
