Abstract

The invention discloses a method for extraction of a natural plant-based anti-mite antibacterial material and preparation of a finishing agent and an application. The method comprises the following steps: A, extracting a natural plant anti-mite antibacterial material, and extracting effective components from mixed plant materials of dried houttuynia cordata, coptis chinensis and radix sophorae flavescentis by an ultrasonic reflux low-temperature extraction method; and B, preparing the natural plant anti-mite antibacterial finishing agent; firstly, adding an aqueous acrylate adhesive into a liquid anti-mite antibacterial extraction liquid obtained in the step A according to a certain proportion, and stirring for 1-2 h; and then adding deionized water, and stirring for 1-1.5 h, and thus obtaining the stable natural plant anti-mite antibacterial finishing agent. The invention also aims to provide an application of the natural plant anti-mite antibacterial finishing agent in mite and bacteria prevention of fabrics; the finishing agent is prepared by the natural plant anti-mite and anti-bacterial effective components, the fabrics are finished by a dipping and rolling method; the finishing agent has excellent anti-mite and anti-bacterial dual functions, the original hand feeling style of the fabrics is maintained, and a formed anti-mite and anti-bacterial material coating layer has excellent washing resistance property.

Description

technical field [0001] The invention relates to the preparation and application of a natural plant anti-mite and antibacterial material extraction and finishing agent, which belongs to the field of biotechnology and functional textile development and application. Background technique [0002] Anti-mite and antibacterial functional textile and clothing products, as new products that can protect people's health and reduce the spread of diseases, have important practical significance especially in the field of home textiles. However, most of the current anti-mite and antibacterial functional products are mainly based on drugs such as pyrethrins, which have poor anti-mite and antibacterial performance and strong biological toxicity. It is of great practical significance to use natural plants to extract active ingredients to prepare highly efficient and non-toxic anti-mite and antibacterial textiles. Contents of the invention [0003] The invention aims at the technical proble...
