A kind of preparation method of antibacterial and antiviral cotton fabric, cotton fabric and application thereof

Abstract

The invention discloses a preparation method of antibacterial and antiviral cotton fabric, cotton fabric and application thereof. The preparation method comprises the following steps: pretreating the cotton fabric to generate reactive free radicals; making the pretreated cotton fabric Soaking in the finishing solution for finishing treatment to introduce at least two different types of antibacterial and antiviral groups on the cotton fabric to obtain the antibacterial and antiviral cotton fabric. The invention uses ultraviolet light or low-temperature plasma to pretreat cotton fabric to generate reactive free radicals, and then enters at least two different types of functional groups with antibacterial and antiviral properties. The cotton fabric of the present invention increases the broad-spectrum antibacterial performance and hydrophilicity of the cotton fabric while maintaining the good moisture absorption and air permeability of chitosan and biocompatibility, and the cotton fabric forms chemical bonds with the antibacterial and antiviral functional groups The connection significantly improves the washability of functional cotton fabrics, and also improves the broad-spectrum antibacterial properties and multi-field adaptability of functional cotton fabrics.

Description

technical field

[0001] The invention relates to the field of cotton fabrics, in particular to a preparation method of antibacterial and antiviral cotton fabrics, cotton fabrics and applications thereof. Background technique

[0002] People are often infested by bacteria and viruses in daily life, affecting people's quality of life, seriously even endangering human life and health. Because ordinary textiles do not have antibacterial properties, they adhere to human secretions during the wearing process of the human body and become a good environment for bacterial growth, endangering human health. The wide application of antibacterial materials began with the prevention of bacterial infections in hospitals and the attention and protection of personal hygiene; in addition, regarding viruses, the SARS (Severe Acute Respiratory Syndrome) virus that broke out in 2003, because it is easy to enter through the respiratory system The human body, the immune system, and the rapid repli...
