Abstract

The embodiment of the invention relates to a production process of a mothproof and bacteriostatic woolen sweater. The production process comprises the following steps of: performing shrink-proof treatment on wool by using a bio-enzyme shrink-proof treatment solution, performing mothproof and bacteriostatic treatment on shrink-proof wool tops by using a mothproof and bacteriostatic treatment solution, preparing mothproof and bacteriostatic wool yarns, and preparing the woolen sweater. The bio-enzyme shrink-proof treatment solution comprises hydrogen peroxide, sodium bicarbonate, sodium hydrogensulfite, compound protease B, silicone, a penetrating agent and an isocyanate-terminated polyurethane prepolymer. The mothproof and bacteriostatic treatment solution comprises a hyperbranched polymer, a mothproofing agent, a silver ion antibacterial agent and an ultraviolet initiator. According to the production process disclosed by the invention, the wool is subjected to shrink-proof treatment,so that the wool has excellent shrink-proof performance. Moreover, by using an ultraviolet irradiation method, the hyperbranched polymer can be well complexed with the wool, and the mothproofing agentand the antibacterial agent can be solidified in an accommodating cavity formed by lots of branched chains in the hyperbranched polymer, so that the woolen sweater has excellent washing resistance.

[0018] Example one

[0019] The production process of a moth-proof and anti-bacterial wool sweater involved in this embodiment includes the following steps: step A is anti-shrinking treatment on wool, step B is anti-moth and anti-bacterial treatment on shrink-proof tops, and step C is anti-moth and antibacterial Preparation of wool yarn, preparation of step D woolen sweater.

[0020] In the anti-shrinkage treatment of wool in step A, the wool top is subjected to water washing pretreatment, the washed wool top is immersed in a biological enzyme anti-shrink treatment solution, and then padding treatment is carried out, with a liquid rate of 70%, and then dried.

[0021] Wherein, the biological enzyme anti-shrink treatment liquid includes the following components in mass percentage: 1% hydrogen peroxide, 1% sodium bicarbonate, 2% sodium bisulfite, 15% compound protease B, 35% silicon Ketone, 7% penetrant, 29% isocyanate-terminated polyurethane prepolymer.

[0022] In the moth-proof and anti-bacterial treatment of the shrink-proof top in step B, the moth-proof and anti-bacterial treatment solution for the top obtained in the previous step is padding, with a liquid rate of 80%, irradiated with ultraviolet light for 5 seconds, and then steamed Heat for 5s and then dry to get moth-proof and anti-bacterial tops.

[0023] Wherein, the moth-proof and anti-bacterial treatment liquid includes the following components in mass percentage: 7% of hyperbranched polymer, 9% of moth-proofing agent, 10% of silver ion antibacterial agent, and 1% of ultraviolet light initiator;

[0024] In the preparation of mothproof and antibacterial wool yarn in step C, the wool top prepared in the previous step is prepared into wool yarn.

[0025] In the preparation of the sweater in step D, the wool yarn prepared in the previous step is prepared into a sweater.

[0026] Further, in step B, the mothproofing agent includes diphenylurea derivatives, polychloro-2-(chloromethanesulfonate) diphenyl ether, and dichlorophenyl ether ester. Specifically, the diphenylurea derivative, polychloro-2-(chloromethylsulfonamido)diphenyl ether, and dichlorophenyl ether ester are mixed in a weight ratio of 1:1:1.

[0027] Further, in step B, the hyperbranched polymer includes a hyperbranched polymer having a terminal amino group, and a hyperbranched poly-3-hydroxymethyloxetane. Specifically, the hyperbranched polymer with terminal amino groups and the hyperbranched poly-3-hydroxymethyloxetane are mixed in a ratio of 2:1 by weight.

[0028] Hyperbranched polymers are homologues of dendrimers. Their structure starts from a central core and spreads out step by step by the branching monomer ABx, or is passed by the central core, several layers of branch units and peripheral groups. Connected by chemical bonds. Due to its unique branched molecular structure, no entanglement between the molecules, and a large number of end groups, hyperbranched polymers exhibit high solubility, low viscosity, high chemical reactivity and many other linear polymers do not have The special performance.

[0029] The hyperbranched polymer with terminal amino groups used in this embodiment has terminal amino groups and can be easily combined with the protein in the wool fiber. After the shrink-proof treatment, the wool has polyurethane and ketones on the surface. The hyperbranched poly-3-hydroxymethyl oxetane used in this example can have good binding ability with it, making it Does not fall off easily after washing.

[0030] In addition, the branch of the hyperbranched polymer forms a containing cavity, which can contain mothproofing agents and antibacterial agents, and the silver ion antibacterial agent can more easily enter the containing cavity formed by the hyperbranched polymer with terminal amino groups. The mothproofing agent is easier to enter the containing space formed by the hyperbranched poly-3-hydroxymethyloxetane branch chain, and can better combine with the wool fiber. In addition, different hyperbranched polymers can be more entangled with each other, so that the two are easily consolidated.

[0031] In addition, the use of ferric chloride as the ultraviolet light initiator can make it easier to combine the hyperbranched polymer with the wool fiber under the irradiation of ultraviolet light. This makes the hyperbranched polymer and wool fiber have greater binding force and is less likely to fall off.

[0032] Diphenylurea derivatives, polychloro-2-(chloromethylsulfonamido)diphenyl ether, and dichlorophenyl ether ester are all mixed with each other, which is easier to form a good mothproof effect and can prevent different kinds of moths.
