Problems solved by technology

[0002] Cotton fabric has the advantages of moisture absorption, breathability, antistatic, and comfortable wearing, but it also has disadvantages such as poor elasticity, easy to wrinkle, and not crisp.
Anti-wrinkle and non-ironing finishing of cotton fabrics is an important post-finishing process to improve fabric wearability and increase its added value. At present, the most used anti-wrinkle finishing agents are amide-formaldehyde finishing agents, especially N-methylolamide compounds. , such as dimethylol dihydroxyethylene urea, this kind of anti-wrinkle finishing is to use the etherification reaction between methylol and the hydroxyl group on the fiber fabric to produce covalent crosslinking to achieve the purpose of anti-wrinkle, and its anti-wrinkle effect Good, but there is a problem of releasing formaldehyde during production and consumption, which limits its promotion and application
Carboxylic acids, acetals, polyurethanes, and epoxy resin anti-wrinkle finishing agents developed in recent years have complicated synthesis process, high price, unsatisfactory finishing effect, serious loss of fabric strength and yellowing phenomenon; prior art The dispersibility of the antibacterial finishing agent in the textile fabric is not very good, which affects the antibacterial performance of the textile fabric

[0033] Step S23, under nitrogen protection, dissolve azobisisobutyronitrile in chloroform, then add 4-vinylpyridine, unsaturated monomer, 2-(perfluorooc...

Embodiment 2

[0036] Preparation of modified silicone oil:

[0037] Step S11: Mix 4,4' dihydroxydiphenyl disulfide, triethylamine and tetrahydrofuran, add acryloyl chloride dropwise at 0 °C, after the dropwise addition is completed, heat up to 30 °C, stir the reaction for 24h, the reaction ends Then, the solvent was concentrated under reduced pressure to remove the solvent, then dissolved in chloroform, washed with potassium carbonate aqueous solution and deionized water in turn, after washing, dried with anhydrous sodium sulfate, and then the solvent was removed by rotary evaporation to obtain unsaturated phenol monomer; , The molar ratio of 4'dihydroxydiphenyl disulfide, triethylamine and acryloyl chloride is 1:1.01:2;

[0038] Step S12, under the condition of temperature of 70°C, add unsaturated phenol monomer and Custer catalyst to the hydrogen-containing silicone oil, after the addition, the temperature is raised to 100°C, and the reaction is performed for 12 hours. After the reaction is...

Embodiment 3

[0040] To prepare the finish:

[0041] The modified silicone oil obtained in Example 2 was mixed with toluene, then isophorone diisocyanate was added, and the reaction was stirred at 80°C for 3 hours. After the reaction, the solvent was removed, and then the temperature was lowered to 20°C, and saturated hydrogen sulfite was added. The sodium continued to stir for 2 hours until the content of -NCO disappeared to obtain a stock solution; then deionized water and alkylphenol polyoxyethylene ether were added, and then the pH value was adjusted to 5 with acetic acid to obtain a finishing agent. The dosage-mass ratio of modified silicone oil and isophorone diisocyanate is 1:1.6; the dosage-mass ratio of stock solution, deionized water and alkylphenol polyoxyethylene ether is 15:50:9.

Abstract

The invention relates to an anti-fouling and crease-resistant garment fabric, which belongs to the technical field of fabrics and is obtained by treating base cloth with a finishing agent, the base cloth comprises cotton fibers and antibacterial fibers, and is obtained by putting the base cloth into a finishing agent and carrying out two times of dipping and two times of rolling, drying and baking; modified silicone oil and diisocyanate are subjected to grafting modification, then sodium hydrogen sulfite is used for blocking to prepare a finishing agent, when the finishing agent is used, deblocking occurs, isocyanate groups react with hydroxyl on the surface of base cloth, crosslinking is performed in a chemical bond mode, the restoring force of the base cloth is improved, and then the anti-wrinkle purpose is achieved. The problem that the dispersity of the finishing agent on the textile fabric is poor is solved. A disulfide bond is introduced into the structure of the modified silicone oil. Due to network rearrangement of disulfide bonds, the cross-linking density is larger, the macromolecular network structure is more complex, better elasticity can be provided after the fabric is finished, and the anti-wrinkle performance of the fabric is improved.
