The technical field is as follows:

the invention relates to the technical field of textile fabric processing, and particularly relates to a green environment-friendly antibacterial and anti-mite fiber fabric for home textiles.

Background art:

one third of the life of people spends on the bed, household textiles such as bed sheets and quilt covers are washed less frequently, most of the household textiles are natural fiber products, cotton fibers can store a large amount of moisture and nutrient substances, and a good environment is provided for the growth of bacteria and mites, so that the most required functions of the home textiles are antibacterial and anti-mite performance.

According to the action mechanism and the way, the antibacterial treatment of the fiber or the textile can be divided into chemical and physical methods, and the physical method is mainly completed by the modes of blending addition in the spinning process, dipping quenching or adsorption in the after-finishing process and the like; the chemical method is mainly completed by introducing a structure with antibacterial and detoxifying functions into a polymer main chain or a side group through copolymerization and grafting methods. The chemical treatment method is easy to prepare the antibacterial detoxifying fiber or textile with durability and uniformity.

At present, various antibacterial textiles seen in the market are basically produced by adopting 3 methods: firstly, an antibacterial agent (often called as an antibacterial finishing agent) is added in the finishing process after printing and dyeing of the fabric, and then various antibacterial textiles are prepared, the method can be used for producing both pure natural fiber or pure chemical synthetic fiber products and blended fiber products, and has wide adaptability, so that most of antibacterial textiles are produced by the method, but the washing fastness of the method is relatively poor; secondly, the antibacterial agent is added into the spinning material to prepare antibacterial fiber, and then various antibacterial textiles are prepared, the method is relatively complex in technology, but relatively good in washing fastness; thirdly, the antibacterial gene is grafted to a reaction group on the surface of the fiber, and for substances without the reaction group, the reaction group is introduced to enable the fiber to have the condition of chemical modification, so that the home textile is manufactured, and the method has narrow adaptability.

Fiber or fabric antimicrobial agents can be classified into two broad categories, organic and inorganic. The inorganic group mainly includes: ag. Metals such as Cu, Au, Zn, Hg, Cd, metal salts and compounds thereof, wherein the silver-carrying antibacterial agent is taken as a representative. The organic substances can be natural or artificial, and the natural substances include chitin such as chitosan, its derivatives, and plant extracts; the synthetic method comprises quaternary ammonium salt, guanidine, phenol, fatty acid and the like, and the quaternary ammonium salt and the polymer derivative thereof are most widely applied at present. The preparation methods of the antibacterial detoxifying auxiliary agents and the corresponding materials thereof have characteristics, and the novel antibacterial detoxifying auxiliary agent which is safe, environment-friendly, efficient and reproducible to human bodies is a development trend.

Therefore, the selection of a proper antibacterial agent and an antibacterial treatment method is the key for preparing the washable antibacterial fabric, and the anti-mite effect needs to be considered at the same time, so that the prepared fabric has double effects of resisting bacteria and preventing mites, and the market competitiveness of the product is improved.

The invention content is as follows:

the invention aims to solve the technical problem of providing the green environment-friendly type home textile antibacterial and anti-mite fiber fabric, which is endowed with excellent antibacterial and anti-mite performance through the preparation of the antibacterial and anti-mite master batch and the addition of the antibacterial and anti-mite master batch in the fabric textile process, can obviously improve the washability of the antibacterial and anti-mite effect of the fabric, and avoids the problem that the antibacterial and anti-mite performance of the fabric is suddenly reduced after being washed.

The technical problem to be solved by the invention is realized by adopting the following technical scheme:

the green environment-friendly type home textile antibacterial and anti-mite fiber fabric is characterized in that a fabric main fiber and an antibacterial and anti-mite auxiliary fiber are made into blended yarns through a spinning process, and then the blended yarns are made into a fiber fabric through a weaving process; the main fiber of the fabric is natural fiber and/or synthetic fiber; the antibacterial and anti-mite auxiliary fiber is prepared from antibacterial and anti-mite master batches through a spinning process.

The mass ratio of the main fiber to the antibacterial and anti-mite auxiliary fiber of the fabric is 90-99: 1-10.

The natural fiber is selected from one or more of cotton fiber, bamboo fiber, hemp fiber and wood fiber.

The synthetic fiber is selected from one or more of polyester fiber, polyamide fiber, acrylic fiber, polyvinyl fiber, spandex fiber and polyolefin fiber.

The antibacterial and anti-mite auxiliary fiber can be made into composite fiber with natural fiber and/or synthetic fiber, thereby widening the application range of the antibacterial and anti-mite master batch and preparing antibacterial and anti-mite fiber fabrics with different materials.

The antibacterial and anti-mite master batch is prepared by preparing allyl isothiocyanate sulfadiazine silver monomer from 2-chloropropenyl isothiocyanate and sulfadiazine silver through substitution reaction, and preparing the antibacterial and anti-mite master batch from the allyl isothiocyanate sulfadiazine silver monomer through polymerization reaction.

Dissolving silver sulfadiazine in a sodium hydroxide solution to obtain a solution I, dissolving 2-chloropropenyl isothiocyanate in N, N-dimethylformamide to obtain a solution II, dropwise adding the solution I into the solution II, heating to 50-70 ℃ for reaction, adding water after the reaction is finished, stirring, filtering, and drying to obtain the propenyl isothiocyanate sulfadiazine silver monomer.

The molar ratio of the silver sulfadiazine to the 2-chloropropenyl isothiocyanate is 1: 1.

The reaction equation for the substitution reaction is as follows:

the polymerization reaction is that propenyl isothiocyanate sulfadiazine silver monomer and initiator are mixed evenly and then fed into a double-screw extruder, and the mixture is subjected to melt reaction at the temperature of 200-250 ℃ and the screw rotation speed of 100-500rpm and then extruded and granulated to obtain the antibacterial and anti-mite master batch.

The initiator is peroxide initiator, azo initiator or the combination of the two.

The polymerization degree of the polymerization reaction is 50-100.

Although silver sulfadiazine belongs to known sulfanilamide/silver salt antibacterial drugs, the sulfadiazine silver is generally used for treating burn and scald wound infection. The monomer containing the isothiocyanate and the silver sulfadiazine group is prepared from the 2-chloropropenyl isothiocyanate and the silver sulfadiazine through a substitution reaction, and the antibacterial and anti-mite master batch is prepared from the monomer through a polymerization reaction, so that on one hand, the washability of silver ions is improved through a chemical bond connection mode, and the antibacterial and anti-mite master batch containing the silver ions is prepared into fibers and then is prepared into composite fibers with natural fibers and/or synthetic fibers through a blending process, and the silver ions are wrapped in the composite fibers, so that the washability of the silver ions is further improved; on the other hand, the introduction of the isothiocyanate group can further optimize the antibacterial and anti-mite effects of the fabric.

The spinning process, the spinning process and the weaving process adopted in the technical scheme all adopt the existing processes in the field.

The invention has the beneficial effects that: the invention adopts non-release type high molecular antibacterial anti-mite agent (i.e. antibacterial anti-mite master batch), which can act on the cell membrane of bacteria to make the bacteria unable to breathe and cause the death of the bacteria, and can avoid and kill mites simultaneously, so that the mites cannot survive and propagate on textiles, and has outstanding washability, reliable and durable antibacterial anti-mite effect, the bacteriostasis rate of staphylococcus aureus, escherichia coli and candida albicans can reach more than 99%, and the avoidance rate of the mites can reach more than 97%.
