Embodiment approach

[0054] As mentioned above, in the preparation methods of existing antibacterial textiles, some antibacterial agents are added to textile raw materials to make antibacterial fibers, and then spun into various antibacterial fabric products. High; Some are made of various antibacterial textiles by adding antibacterial agents in the finishing process of textile printing and dyeing. This method has the problems of poor antibacterial effect persistence and poor washability. However, the existing antibacterial agents all have the problems of not lasting antibacterial effect and poor washability, and there are also risks of toxicity, skin irritation and drug resistance caused by the release of antibacterial agents. In view of this, the inventor has carried out a large amount of research on antibacterial natural textile materials.

[0055] The present inventors have found that a new antibacterial strategy of surface stereochemistry can be used to prepare an antibacterial natural texti...

Embodiment 1

[0109] Soak the pretreated cotton textiles in an acetone solution with a concentration of 10vol% 3-aminopropyltriethoxysilane for 10 minutes, then take it out and heat it at 50°C for 2 hours to promote the formation of covalent bonds, and finally acetone thoroughly Excessive aminosilane was washed off and dried to obtain aminosilane-modified cotton textiles. Then soak it in an ethanol solution of D-borneol derivatives with a concentration of 0.02 g / mL, and soak for 1 hour at room temperature. Finally, the excess uncombined borneol derivatives are thoroughly washed with ethanol, and dried to obtain borneol-modified cotton textiles. The anti-bacterial adhesion rate is greater than 90%, and the anti-fungal effect is greater than 25 days (using experimental strains: Escherichia coli, Staphylococcus aureus, Aspergillus, Mucor, etc.).

Embodiment 2

[0111] Soak the pretreated cotton textiles in an acetone solution of 10vol% 3-aminopropyltrimethoxysilane for 10 minutes, then take it out and heat it at 60°C for 2 hours to promote the formation of covalent bonds, and finally wash it thoroughly with acetone Remove excess aminosilane and dry to obtain aminosilane-modified cotton textiles. Then soak it in an ethanol solution of L-borneol derivative with a concentration of 0.02g / mL, and soak it for 2h at room temperature. Finally, the excess uncombined borneol derivatives are thoroughly washed with ethanol, and dried to obtain borneol-modified cotton textiles. The anti-bacterial adhesion rate is greater than 90%, and the anti-fungal effect is greater than 25 days (using experimental strains: Escherichia coli, Staphylococcus aureus, Aspergillus, Mucor, etc.).

Abstract

The present invention relates to a borneol surface-modified antimicrobial natural textile material, using a new antimicrobial strategy of surface stereochemistry, obtained by means of a natural textile material coupled to aminosiloxane and a borneol 4-aldehyde benzoate derivative, reaction conditions of a preparation process being mild, and the preparation technique being simple. The antimicrobial natural textile material is a non-release type antimicrobial textile material, and will not release bactericide to kill a microorganism, instead affecting microorganism adhesion by means of a material surface stereochemical structure, which can ensure safety of use, will not stimulate and sensitize skin, and will not harm natural skin flora; in addition, the present material has good anti-adhesion functionality for both bacteria and fungi, capable of effectively inhibiting bacterial and fungal adhesion in the long term, and the structure is stable and washable. The present antimicrobial natural textile material is a safe, stable and environmental new antimicrobial natural textile product, which may be wide used in the medical, hygiene, environmental and clothing industries.

Description

technical field [0001] The invention belongs to the field of biological antibacterial materials, and relates to an antibacterial natural textile material with surface-modified borneol, a preparation method and application thereof. Background technique [0002] Natural textiles are widely used in people's daily life, such as clothing, bed sheets, masks, white clothes and medical gauze, etc., but they also provide a breeding ground and medium for the growth, reproduction and spread of harmful microorganisms, which seriously threaten human beings during use health. With the advancement of science and technology and the improvement of people's awareness of hygiene and safety, people have also put forward higher requirements for the antibacterial properties of textiles. Therefore, how to meet the requirements of endowing textiles with efficient and durable antibacterial function without affecting the appearance and safe use of textiles has become a research hotspot of common con...
