AI Technical Summary

Problems solved by technology

Nano-titanium dioxide has the characteristics of large specific surface area and specific surface energy, and it is easy to agglomerate; and the surface of nano-titanium dioxide has strong polarity, and there is no binding force with cotton fibers, which is easy to cause interface defects, resulting in hard hand feeling and poor air permeability of the material fabric. Problems such as poor washing fastness and poor functional durability
[0004] Some commonly used organic antibacterial materials have weak antibacterial properties, poor heat resistance and stability, self-decomposition products and volatiles may be harmful to the human body, and are not suitable for high-temperature processing. Their applications are limited.

Synthetic example

[0031] In a nitrogen atmosphere, add 1L of divinyltriamine, 5L of thioacetamide aqueous solution (2wt%), and 800mL of methyl acrylate dropwise into 2L of methanol, and react at 30°C for 2h; then rotary evaporate to remove methanol, and continue the reaction under reduced pressure at 140°C After 6h, the reaction was stopped to obtain an amino-terminated hyperbranched compound.

Embodiment

[0033] Immerse the cotton fibers in the cotton fiber finishing solution according to the bath ratio 1:60, shake; soak at 60°C for 15 minutes, and dry at 120°C; then soak in the cotton fiber finishing solution, soak at 80°C for 8 minutes, 120°C °C drying; washing and drying to obtain antibacterial cotton material; wherein the composition of the cotton fiber finishing solution is shown in Table 1.

Abstract

The invention relates to a preparation method for an anti-microbial cotton material. Cotton fibers are placed in a finishing liquid comprising amino-terminated hyperbranched polymers, micromolecule functional agents, ytterbium fluoride and nano-titanium dioxide, dipping treatment is carried out, and anti-microbial cotton fibers are obtained. The cotton fibers finished through the method has good hand feeling, air permeability and fastness to washing and has strong anti-microbial endurance. Treatment is convenient, the method is simple, and operation is easy.

Description

technical field [0001] The invention belongs to the technical field of fiber composite materials, and in particular relates to a preparation method of an antibacterial cotton material, which has high antibacterial properties. Background technique [0002] Cotton-type textile material is a textile material with a lot of contact with the human body. During the contact process with the human body, the sweat, cortex and other secretions of the human body become a good source of nutrition for various microorganisms. Under suitable external conditions, microorganisms grow rapidly. , reproduction, and spread diseases through various channels, threatening the survival and development of human beings. Therefore, with the improvement of health awareness and the rapid development of science and technology, the development of pure cotton textiles with bactericidal and antibacterial functions has attracted people's attention. [0003] The particle size of nano-titanium dioxide is betwee...
