Embodiment 1

[0014] A preparation method of inorganic nanometer antibacterial cotton fiber, comprising the following steps:

[0015] a. Place the cotton fiber into the antibacterial finishing agent and soak for 5 minutes. It should be pointed out that the carrier of the antibacterial finishing agent is nano-TiO 2 ; The pH value of the antibacterial finishing agent is 4-5;

[0016] b. Pressing the cotton fiber soaked in the antibacterial finishing agent. The above padding steps are repeated two to three times, and the liquid-carrying rate of the cotton fibers during the padding process is 70% to 80%, so as to ensure a good padding effect. The pressure of each rolling is 45kn.

[0017] c. Baking the pressed cotton fiber at a temperature of 150-170°C for 120s.

[0018] The antibacterial rate of the cotton fiber after finishing is as high as 99.9%, and the antibacterial zone is 17mm. After 10 times of washing, the antibacterial effect remains unchanged; the number of times of washing resis...

Embodiment 2

[0020] When rolling cotton fiber, the pressure of each rolling is 40kn. All the other are with embodiment 1.

Embodiment 3

[0022] When rolling cotton fiber, the pressure of each rolling is 50kn. All the other are with embodiment 1.

[0023] The present invention adopts nanometer TiO 2 It is the carrier of silver ion antibacterial agent, and releases silver ion with antibacterial effect in wet state (such as perspiration). Due to nano TiO 2 The silver ion antibacterial agent used as the carrier has great surface activity, and 1g of nano-scale antibacterial finishing agent has about 600,000cm 2 The surface area, a small amount can achieve good results.

Abstract

A preparation method of inorganic nano antibiotic cotton fiber comprises padding antibiotic finishing agent and drying; the antibiotic finishing agent comprises Ag ion antibiotic agent, the carrier of the Ag ion antibiotic agent is nano TiO2, and the pH value of the Ag ion antibiotic agent is 4-5. The invention has the beneficial effects that the invention adopts nano TiO2 as the carrier of the Ag ion antibiotic agent, so as to in a wet state (e.g. sweating) release Ag ions with antibiotic effect. As the Ag ion antibiotic agent taking nano TiO2 as the carrier has larger surface activity, 1g of nano-level antibiotic finishing agent has about a surface area of 600000cm<2>, and a little amount of the agent can achieve better effect.

Description

technical field [0001] The invention relates to the field of textile technology, in particular to a preparation method of inorganic nanometer antibacterial cotton fiber and its application in home textile products. Background technique [0002] Natural cotton fibers are popular with consumers because of their comfort, etc., but they have some disadvantages, such as cotton fibers are much more sensitive to mold and fungal attack than synthetic fibers, and under suitable conditions, some pathogenic bacteria such as golden yellow Staphylococcus, Escherichia coli, Candida albicans and Salmonella typhi exist on cotton fibers for a long time, and they multiply rapidly with the body's metabolic products-sweat, fat and dander as nutrients, decomposing various low-level fatty acids and amines Odor-smelling volatile compounds such as bacteria, plus the secretions of bacteria themselves and the smell of their dead bodies decomposing, textiles release disgusting odors. This not only di...
