preparation example Construction

[0026] The present invention also provides a kind of preparation method of antibacterial fabric, comprises the following steps:

[0027] Step (1) Preparation of N-2-hydroxypropyltrimethylammonium chloride chitosan: chitosan is dissolved in dilute acetic acid solution, and glycidyltrimethylammonium chloride is added to the reaction system, the shell The molar ratio of polysaccharide to glycidyltrimethylammonium chloride is 1:5, then adjust the pH value of the solution to 6.0-6.5 with dilute hydrochloric acid, and react at 85°C for 14 hours. After the reaction, the product is precipitated with ethanol. Filter, and finally wash the product with 70% ethanol aqueous solution to obtain a crude product, dissolve the crude product in water, and filter with a sand core funnel, the filtrate is precipitated with acetone, and the solid final product N-2-hydroxypropyl trimethyl is obtained after filtering again ammonium chloride chitosan.

Abstract

The invention relates to an antibacterial fabric and a preparation method thereof. The antibacterial fabric comprises a fabric base material and a composite microcapsule antibacterial agent added into the fabric base material. The preparation method of the antibacterial fabric comprises the following five steps of preparation of N-2-hydroxypropyltrimethylammonium chloride chitosan, an emulsification reaction, a complex coacervation reaction, a cross-linking reaction, and combination of the composite microcapsule antibacterial agent and the fabric base material. According to the invention, the antibacterial active component, namely the N-2-hydroxypropyltrimonium chloride chitosan, thujopsis dolabrata oil and fennel oil are used for preparing a microcapsule, so that the fabric has an efficient antibacterial effect, good slow-release performance and good safety performance, is good in washing resistance, can still keep good antibacterial performance after being used for a long time, and has a wide industrial application prospect.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to an antibacterial fabric and a preparation method thereof. Background technique [0002] With the development of human science and technology and the improvement of people's living standards, while people pay attention to the beauty and comfort of fabrics, they also put forward higher requirements for the hygiene of fabrics. Antibacterial fabrics have gradually become an important emerging industry field.
