Abstract： |
The preparation method of macromolecular anti-bacterial fibre with surface high-grafting ratio belongs to the field of macromolecular material, and includes the following steps: firstly, making acryl chloride containing C equal to C unsaturated double bond and tertiary amine monomer matter with OH group produce reaction, adding triethylamine as adjuvant to obtain tertiary amine with C equal to C bond, adding benzyl chloride, making reflux reactino, adding macromolecular fibre and initiator, after reaction is completed, using solution to stir and rinse reaction product, suction filtering and drying so as to obtain the invented product. By means of infrared spectrum analysis, TGA analysis and weighing analysis these analysises show that the monomer is grafted and polymerized on the surface of fibre, and grafting ratio range is 50%-150%. |
