Problems solved by technology

[0005] The technical problem mainly solved by the present invention is to solve the problem of poor washing resistance of traditional fabric stiffeners during use, decreased fabric stiffness and elasticity after being damp, and the treated fabrics are prone to mildew during storage , provides a preparation method of using insect secretions as antibacterial components and wrapping them with modified carboxymethyl chitosan to obtain a stiffening agent for non-ironing clothing fabrics. The present invention first injects Escherichia coli mycelium suspension into Starvation treated Tenebrio molitor larvae produces a large amount of antibacterial ingredients in the body, then collects its body fluids, purifies them after centrifugation, and uses them as stiffening agent antibacterial ingredients, and then uses dodecyl glycidyl ether to graft and modify the hydrophilic type The carboxymethyl chitosan of carboxymethyl chitosan makes it amphiphilic, wraps Tenebrio molitor larvae extract, mixes with polyvinyl alcohol etc. to form uniform emulsion again, makes non-ironing garment fabric fabric stiffening agent, the fabric stiffening agent gained in the present invention is used In the process, modified carboxymethyl chitosan is used to form a firm three-dimensional network structure in the pores of the fabric, and the coated antibacterial ingredients can be released slowly, which effectively solves the problem of poor washing resistance of traditional fabric stiffeners and easy mildew during storage. changing problem

example 1

[0018] First, inoculate Escherichia coli on the surface of the solid medium with an inoculation amount of 2%, then move the solid medium into a constant temperature incubator, and culture it at a constant temperature for 2 days at a temperature of 35°C, then rinse the surface of the medium with 200mL deionized water , to obtain mycelia suspension, the solid medium is mixed with 10g tryptone, 6g beef extract, 0.6g sodium chloride, 13g agar powder, and 800mL deionized water; then select 30 heads and raise them to the 3rd age Tenebrio molitor larvae were placed in an incubator and starved for 36 hours, then 1 μL of the above-mentioned mycelial suspension was injected into the abdomen of each Tenebrio molitor larvae through a micro-syringe, and then the Tenebrio molitor larvae were fed normally for 36 hours. Remove the forefoot of the larvae, collect the effluent with a capillary tube, transfer the obtained effluent to a centrifuge, and centrifuge for 25 minutes at a speed of 8000r...

example 2

[0021] First, inoculate Escherichia coli on the surface of the solid medium with an inoculation amount of 3%, then move the solid medium into a constant temperature incubator, and culture it at a constant temperature for 2 days at a temperature of 36°C, and then rinse the surface of the medium with 250 mL of deionized water , to get mycelia suspension, the solid medium is mixed with 13g tryptone, 7g beef extract, 0.7g sodium chloride, 14g agar powder and 900mL deionized water; then choose 35 heads to raise to 3 ages Tenebrio molitor larvae were placed in an incubator and starved for 42 hours. Then, 2 μL of the above-mentioned mycelia suspension was injected into the abdomen of each Tenebrio molitor larvae through a micro-syringe, and then the Tenebrio molitor larvae were fed normally for 54 hours. Remove the forefoot of the larvae, collect the effluent with a capillary tube, transfer the obtained effluent to a centrifuge, and centrifuge for 28 minutes at a speed of 9000r / min, d...

example 3

[0024] First, inoculate Escherichia coli on the surface of the solid medium with an inoculation amount of 4%, then move the solid medium into a constant temperature incubator, and culture it at a constant temperature for 3 days at a temperature of 37°C, and then rinse the surface of the medium with 300mL deionized water , to get mycelia suspension, the solid medium is mixed with 15g tryptone, 8g beef extract, 0.8g sodium chloride, 15g agar powder and 1000mL deionized water; select 40 heads to raise to 3 years old Tenebrio molitor larvae were placed in an incubator and starved for 48 hours, then 3 μL of the above-mentioned mycelium suspension was injected into the abdomen of each Tenebrio molitor larvae through a micro-syringe, and then the Tenebrio molitor larvae were normally raised for 72 hours. Remove the forefoot of the larvae, collect the effluent with a capillary tube, then transfer the obtained effluent to a centrifuge, and centrifuge for 30 minutes at a speed of 10,000r...

Abstract

The invention discloses a preparation method of a non-ironing garment material fabric stiffening agent and belongs to the technical field of printing and dyeing auxiliaries. The preparation method comprises the steps that firstly, escherichia coli suspension liquid is injected into hungering yellow mealworm larvae to produce a large amount of antibacterial components in the larvae, then body fluid of the larvae is collected and is subjected to centrifugal separation and purification to serve an antibacterial component of the stiffening agent, the dodecyl glycidyl ether is utilize to graft modified hydrophilic carboxymethyl chitosan and make the modified hydrophilic carboxymethyl chitosan have amphiphilicity, the modified hydrophilic carboxymethyl chitosan is coated with a yellow mealworm larva extract and then is mixed with polyvinyl alcohol and the like into an uniform emulsion, and the non-ironing garment material fabric stiffening agent is prepared. The prepared non-ironing garment material fabric stiffening agent utilizes the modified carboxymethyl chitosan to form a firm three-dimensional network structure in fabric pores in the using process and can make the coated antibacterial component slowly released, and the problem that a traditional fabric stiffening agent is poor in wash resistance property and does not mildew in the storage process.

Description

technical field [0001] The invention discloses a preparation method of a non-ironing fabric stiffener, belonging to the technical field of printing and dyeing auxiliaries. Background technique [0002] The stiffness, smoothness and fullness of the fabric are called the three basic styles of the fabric. Many fabrics have strict requirements on the stiffness of their fabrics. Stiffeners have become an important part of finishing aids. Stiffening finishing is to pad the stiffening agent to make the fibers in the fabric yarn bond under certain conditions. The stiffening agent forms a film or cross-links inside the fiber, between the fibers or on the surface of the fiber, so that the fabric is produced. Firm, thick, full-bodied feel. It is widely used in the finishing process of decorative fabrics, especially the stiffening of curtain fabrics, bag fabrics, warp knitted fabrics and interlinings. [0003] The commonly used types of stiffeners are urea-formaldehyde resin, melami...
