Abstract

The invention discloses an antibacterial fabric and a preparation method thereof and belongs to the technical field of textile production. The hyperbranched polymer obtained by modifying a quaternaryammonium salt structure is used for antibacterial finishing of fabrics, on one hand, the hyperbranched polymer has high solubility, the washing resistance is improved; on the other hand, long-chain alkyl is introduced in the substitution process, the cytotoxicity is reduced, and a hydrophobic group and a hydrophilic group deeply penetrate into lipid layers and protein layers of bacterial cells respectively, so that the antibacterial performance is enhanced. After an epoxy group and a hydroxyl group of starch produce etherification action, the long-acting antibacterial property is formed, the performance of the fabric is improved, the plasticizing effect on the fiber is achieved, the antibacterial efficiency is improved, the plasticity and entanglement performance of the fiber are improved,the mechanical property and toughness of the fabric are improved, and the antibacterial efficiency is also increased. The problem is solved that an antibacterial additive in an existing antibacterialfabric is high in toxicity and has the influence on the mechanical property of the fabric itself.

Description

technical field [0001] The invention belongs to the technical field of textile production, and in particular relates to an antibacterial fabric and a preparation method thereof. Background technique [0002] With the gradual improvement of people's living standards, personal hygiene and health issues have been paid more and more attention. As a necessity of human life, fiber textiles have been paid more and more attention to their safety and hygiene functions. Under this social trend, the research on various antibacterial fabrics has developed rapidly in the past two decades. And since the 21st century, the successive outbreaks of major infectious diseases including SARS, bird flu, and H1N1 flu have once again threatened the safety of human life, and have also put forward more stringent requirements for public health. [0003] In daily life, people will inevitably come into contact with various microorganisms, including bacteria, viruses, fungi and algae. All kinds of bac...
