Antibacterial additive and preparation method thereof

Abstract

The invention discloses an antibacterial additive and a preparation method thereof. The antibacterial additive is prepared from the following raw materials in parts by weight: 30-40 parts of ternary copolymer dimethylsiloxane, 20-25 parts of bis-(tallow amide hexyl)-polyethoxymethyl ammonium-methyl sulfate, 5-7 parts of hydroxyl modified polydimethylsiloxane, 4-8 parts of an emulsifying agent, 0.5-1 part of organic acid, 5-10 parts of a solubilizer and 50-70 parts of water. A quaternary amination and hydroxyl hybrid modification method is adopted; the obtained antibacterial additive is good instability; when the antibacterial additive is applied to fabric, the fabric is enabled to be fine, soft and smooth, and the antibacterial property of the fabric is effectively improved.

Description

technical field

[0001] The invention relates to the technical field of fabric dyeing and weaving auxiliaries, in particular to an antibacterial auxiliaries and a preparation method thereof. Background technique

[0002] In recent years, with the widespread spread of viruses such as Ebola and influenza A, human health has been threatened, and people's demand for textiles with antibacterial functions has become increasingly urgent. As one of the most commonly used fabric finishing agents, silicone oil has the advantages of low surface energy and good film-forming properties. Using it in the finishing of fiber fabrics can not only modify the surface properties of fabrics, but also give fabrics softness, smoothness, etc. Diversity of touch. Existing silicone oils are mostly used as softeners for textile finishing, but less research has been done as antibacterial agents. Contents of the invention

[0003] The inventors of the present invention have found that the quaternary a...
