Abstract
The invention discloses a deodorizing knitted fabric and a manufacturing method thereof. The deodorizing knitted fabric is obtained by finishing polyester knitted fabric with an antibacterial finishing agent, wherein the antibacterial finishing agent is prepared from the following components in parts by mass: 3-7 parts; polyhexamethylene guanidine: 1-3 parts; dispersing agent: 1-2 parts; traditional Chinese medicine antibacterial extracting solution: 15-25 parts; water: 50-70 parts of a solvent; the traditional Chinese medicine antibacterial extracting solution is one or more of cassia twig extracting solution, coptis extracting solution, folium artemisiae argyi extracting solution and wild chrysanthemum extracting solution. The deodorization looped fabric that this application was made has better antibacterial property and deodorization performance to improve the looped fabric and breed the problem that the peculiar smell appears because of the bacterium.
Description
Technical Field
The invention relates to the field of cloth, in particular to a deodorizing knitted fabric and a manufacturing method thereof.
Background
The knitted fabric is formed by bending yarns into a set and stringing the yarns, and has the advantages of soft texture, moisture absorption and air permeability. Accordingly, knit fabrics are widely used in the manufacture of undergarments, such as underwear and socks. It can significantly improve the wearing comfort compared to woven fabrics. However, in high temperature weather, the underwear easily absorbs sweat on the surface of the human body, so that bacteria are bred and peculiar smell is emitted, which is not beneficial to ensuring human health and improving wearing experience.

TABLE 3 test 1-4 test results
And (3) analyzing test results:
(1) by combining the examples 1-15 and the comparative examples 1-5 and combining the table 3, the antibacterial and deodorizing performance of the knitted fabric can be remarkably improved by adopting the traditional Chinese medicine antibacterial extracting solution; and the traditional Chinese medicine antibacterial extracting solution obtained by compounding the four extracting solutions of the cassia twig, the coptis chinensis, the wild chrysanthemum and the folium artemisiae argyi can effectively reduce pungent smell in the traditional Chinese medicine and improve customer experience. The reason for this is probably that the cassia twig extract, the coptis chinensis extract, the folium artemisiae argyi extract and the wild chrysanthemum extract all contain more antibacterial components, and when the cassia twig extract, the coptis chinensis extract, the folium artemisiae argyi extract and the wild chrysanthemum extract are arranged on the surface of a fabric or in fibers of the fabric, the growth of bacteria can be effectively inhibited, and odor substances generated due to the growth and reproduction of the bacteria are further reduced. The cassia twig, wild chrysanthemum and folium artemisiae argyi extract also contains a certain amount of aromatic substances, and the aroma smell of the extract can cover the peculiar smell emitted by the bacterial products to a certain extent, so that the aims of antibiosis and deodorization are fulfilled. The aromatic substances of the cassia twig extract, the wild chrysanthemum extract and the folium artemisiae argyi extract, especially the faint scent of the wild chrysanthemum can neutralize the irritant traditional Chinese medicine smell in the coptis chinensis, and the smell evaluation of customers on knitted fabric products is improved.
(2) By combining the example 1 and the comparative examples 4-8 and combining the table 3, the polyvinyl alcohol and the silane coupling agent can effectively improve the water washing resistance of the deodorizing knitted fabric and prolong the long-acting property of the antibacterial and deodorizing performance of the deodorizing knitted fabric; and the silane coupling agent is preferably a compound of an aminosilane coupling agent and a long-chain alkyl silane coupling agent. The reason for this is probably that polyvinyl alcohol can form a certain network cross-linking structure with waterborne polyurethane, while aminosilane coupling agent can enhance the bonding strength between the antibacterial and deodorant coating film and the fiber, and long-chain silane coupling agent can improve the hydrophobicity of the antibacterial and deodorant coating film, so that the knitted fabric can still maintain good antibacterial and deodorant performance after being washed with water for many times.
(3) By combining the example 1 and the comparative examples 9-15 and combining the table 3, it can be seen that the antibacterial and deodorant performances, especially the long-acting performance, of the knitted fabric can be remarkably improved by adding the deodorant particles and the nano titanium dioxide before the esterification of the PET. The reason may be that the addition of the catalyst before esterification enables in-situ polymerization of terephthalic acid and ethylene glycol on the surfaces of the deodorizing particles and the nano titanium dioxide, so as to form nano particles coated with polyethylene terephthalate, improve the compatibility and the dispersibility of the nano particles, reduce the falling off of the deodorizing particles and the nano titanium dioxide in water washing or use, and further improve the long-lasting property of the antibacterial and deodorizing performance of the knitted fabric.
