Production method of multifunctional textile finishing agent

Abstract

A skeleton template for synthesis of nano silver is made with DNA, so that growth of nano silver can be effectively limited, and agglomeration of the nano silver is prevented. The nano silver grown isin chain shape. Compared with spherical nano silver, the nano silver herein under the same concentration has better antibacterial or antistatic effect; DNA is bio-based macromolecules, so that the agent is green, the sources of materials are rich, the macromolecular chains contain massive phosphorus and nitrogen long-chain polymers as well; under heating, phosphorus-nitrogen synergistic flame retardance can be achieved, and the flame retarding effect is significant; nano DNA / Ag is multifunctional powder that can inhibit bacteria and electrostatic electricity and retard inflaming; the multifunctional finishing agent uses a waterborne UV curing system, water is used as a dispersing medium which is green; after the agent is used to finish cloth, and finishing can be performed just through reaction for 30 s to 2 min under ultraviolet exposure; compared with traditional high-temperature baking modes, the production method is simple to perform, significant in advantage and easy to use to implement industrial production.

Description

technical field [0001] The invention relates to the field of preparation of fabric finishing agents, in particular to a preparation method of an antibacterial, flame-retardant and antistatic fabric finishing agent. Background technique [0002] With the improvement of people's living standards and the development of dyeing and finishing technology, people's requirements for fabrics are not limited to their original functions, and endowing fabrics with multifunctionality has become a new demand for people to wear, such as waterproof, oil-proof, anti-fouling, anti-fouling, etc. Static electricity, anti-ultraviolet, antibacterial, flame retardant, etc. [0003] In daily life, the most impossible thing for people to avoid is contact with various bacteria, fungi, etc., especially in the Huangmei weather in the south, where bacteria breed faster. Therefore, endowing fabrics with long-lasting and efficient antibacterial properties is very important for improving people's quality of...

AI Technical Summary

Problems solved by technology

The research comparison found that inorganic flame retardants have low flame retardant efficiency, poor compatibility with polymer matrix, and affect the wearability of fabrics to a certain extent

Although halogen-based flame retardants have better flame retardant effects, they will release harmful and toxic gases when they are thermally cracked, which is not environmentally friendly. Therefore, the greening of flame retardants has become an inevitable trend in the development of flame retardant technology.
