Problems solved by technology

[0003] However, the finishing temperature of some haloamine compounds is higher, the time is longer, and the energy consumption is high; some hydroxyl-containing compounds need to be grafted with cellulose under the action of a crosslinking agent, and the cotton fiber is easily Hydrolytic degradation occurs, the degree of polymerization decreases, and the tensile breaking strength of the fabric is significantly reduced, which seriously affects the wearability of the fabric; the water solubility is poor, and a large amount of flammable solvents must be added to help dissolve when used, which not only increases the cost of finishing and wastewater treatment, but also There are security risks

Embodiment 1

[0022] Add (3-acrylamidopropyl) trimethylammonium chloride that final concentration is 100g / L to water, add the initiator sodium persulfate that final concentration is 0.1mol / L again, configure finishing liquid; The fabric is placed in the finishing solution, reacted at 60°C for 3 hours, and then washed with detergent for 15 minutes to remove unreacted monomer substances on the surface, then washed with clean water to remove the detergent on the surface of the fabric, after drying, wash with 10wt% sodium hypochlorite solution Chlorination for 1 hour, washing and drying to obtain the finished antibacterial cotton fabric. After testing, the effective chlorine content of the finished fabric is 0.06%.

Embodiment 2

[0024] Add (3-acrylamidopropyl) trimethylammonium chloride that final concentration is 100g / L in water, add the initiator potassium persulfate that final concentration is 0.3mol / L again, configure finishing liquid; The fabric is placed in the finishing solution, reacted at 60°C for 3 hours, and then washed with detergent for 15 minutes to remove unreacted monomer substances on the surface, and then washed with clean water to remove the detergent on the surface of the fabric. After drying, chlorinated with 10wt% sodium hypochlorite solution for 1 hour, washed and dried to obtain the finished antibacterial cotton fabric. After testing, the effective chlorine content of the finished fabric was 0.12%.

Embodiment 3

[0026] Add (3-acrylamidopropyl) trimethylammonium chloride that final concentration is 100g / L in water, add the initiator potassium persulfate that final concentration is 0.4mol / L again, configure finishing liquid; The fabric is placed in the finishing solution, reacted at 70°C for 3 hours, and then washed with detergent for 15 minutes to remove unreacted monomer substances on the surface, and then washed with clean water to remove the detergent on the surface of the fabric. After drying, chlorinated with 10wt% sodium hypochlorite solution for 1 hour, washed and dried to obtain the finished antibacterial cotton fabric. After testing, the effective chlorine content of the finished fabric is 0.10%.

Abstract

The invention discloses a preparation method of olefine halamine compound grafted antibacterial cotton fabric containing quaternary ammonium groups. The method comprises the following steps of: (1) preparing finishing liquid: adding an olefine halamine compound precursor containing quaternary amine groups at the final concentration of 50-150g / L into water, adding an initiator at the final concentration of 0.1-0.4mol / L to prepare the finishing liquid, and (2) antibacterial finishing: putting cotton fabric to be treated in the finishing liquid for reaction at 50-70 DEG C for 1-5h, soaping, washing with water, airing, chloridizing, and obtaining the antibacterial cotton fabric finish product, wherein a chemical structural formula of the precursor is as shown in Formula (I). The method is simple in technology, low in energy consumption and short in time, and an antibacterial test and a fabric strength test show that the prepared antibacterial cotton fabric has excellent antimicrobial property and good wearability, and has an important industrial application value.

Description

technical field [0001] The invention belongs to the technical field of textile production and antibacterial materials, and in particular relates to a method for preparing antibacterial cotton fabrics loaded with quaternary ammonium group olefin haloamine compounds. Background technique [0002] Pathogenic bacteria are harmful to human health, and human skin itself has the temperature, nutrients and moisture suitable for the growth of pathogenic bacteria. Therefore, pathogenic bacteria can grow and reproduce rapidly, and then endanger human health. Cotton fabric is the textile material with the most contact with human skin. It has strong hygroscopicity and is more conducive to the growth and reproduction of bacteria. With the improvement of people's living standards and the continuous increase of health awareness, it is particularly important to develop textiles with excellent antibacterial properties. Each glucosyl ring in the cotton fiber molecule contains 3 hydroxyl group...
