Problems solved by technology

[0002] Cotton fibers are used in the preparation of close-fitting clothing because of their sweat-absorbing comfort. However, cotton fibers are prone to deformation and shrinkage after being soaked in water. At the same time, although cotton fibers have strong water-absorbing and sweat-absorbing capabilities, they cannot achieve fast sweat-absorbing effects. It is difficult to dry the inside, making the clothes wet and uncomfortable to wear next to the skin, especially after sweat soaking, the sweat soaks inside the fiber, making the fabric breed bacteria from the inside of the fiber center, causing clothes to smell

Embodiment 1

[0022] The specific preparation process of hydrophobic antibacterial coating agent is as follows:

[0023] ①Add 10g of diphenylsilanediol to 170mL of acetone solution, raise the temperature to 100-110°C and stir for 20-30min, then add 2.1g of p-toluenesulfonic acid and 7.2g of cis-aconitic anhydride, and raise the temperature to 250- Reflux at 260°C for 20-22 hours to obtain a polymer solution;

[0024] ②Then lower the temperature in the reaction vessel to 90-95°C, add 7.6g of azobisisobutyronitrile and 15.7g of allyl mercaptan into the reaction vessel at the same time, stir and reflux for 1-2h, then raise the temperature to 120-130°C Reflux for 4-5 hours to obtain a hydrophobic antibacterial coating agent.

Embodiment 2

[0026] The specific preparation process of antibacterial finishing agent is as follows:

[0027] Step 1: Add 11g of resorcinol to 150mL of water, and at the same time add hydrochloric acid to adjust the pH of the solution to 1, then add 8.1g of 37% formaldehyde solution and 16.7g of acetylhydrazide trimethyl chloride to the reaction vessel Ammonium chloride, heated to 60-70°C and stirred for 10-12h, then evaporated to remove the solvent and washed to neutral to obtain phenolic hydroxyl ammonium chloride;

[0028] Step 2: Add 10 g of phenoxyammonium chloride prepared in Step 1 into 80 mL of water and stir to dissolve, then adjust the pH of the solution to 13, then add 3.5 g of formaldehyde solution with a mass fraction of 37% to it, and heat up to 50-60°C Stir the reaction for 2-3h, then add 6.2g of formaldehyde solution with a mass fraction of 37% to the reaction vessel, raise the temperature to 100-110°C for reflux reaction for 5-6h, and then carry out vacuum distillation to ...

Abstract

The invention discloses a preparation method of a cotton-based antibacterial composite fabric. The preparation method specifically comprises the following steps: adding treated cotton fibers into a hydrophobic antibacterial coating agent, soaking the cotton fibers with the hydrophobic antibacterial coating agent, then drying the cotton fibers, adding a silver nitrate solution with the mass concentration to soak the cotton fibers, adding the obtained fibers into an antibacterial finishing agent to soak, and steaming the fibers in hot water to obtain antibacterial hydrophobic cotton fibers; andweaving the prepared antibacterial comfortable cotton fibers into yarns, and then weaving the yarns into a fabric to obtain the cotton-based antibacterial composite fabric. An antibacterial hydrophobic layer is firstly loaded on the surfaces of the fibers, and then a porous water absorption layer is loaded on the surface of the antibacterial hydrophobic layer, so that the effect of instantaneous absorption of the cotton fibers is achieved, and the water absorption rate of the cotton fibers is improved; and moreover, the inner layer is a hydrophobic layer, after permeating out of the water absorption layer, sweat is intercepted between the water absorption layer and the hydrophobic layer by the hydrophobic layer, and does not permeate into the centers of the fibers, the water absorption layer of the outer layer contains a large number of gaps, and thus, the cotton fibers can be dried quickly.
