| titleOfInvention | A kind of method for hydrophilic modification of polylactic acid fiber |
| abstract | The invention belongs to the technical field of hydrophilic modification of polylactic acid fibers, in particular to a method for hydrophilic modification of polylactic acid fibers. In view of the problem of poor hydrophilicity of polylactic acid proposed in the background art, the following solutions are now proposed, including lactic acid 40- 60 parts, 10-15 parts of maleic anhydride, 30-40 parts of ethylenediamine, 3-5 parts of benzoyl peroxide, 1-2 parts of acetone, 1-2 parts of tetrahydrofuran, S1, the synthesis of lactide; S2 , Synthesis of maleic anhydride modified polylactic acid; S3, purification of maleic anhydride modified polylactic acid; S4, synthesis of ethylenediamine modified polylactic acid. In the present invention, lactic acid is first made into lactide, and then the ethylenediamine-modified polylactic acid is obtained by sequentially mixing lactide, maleic anhydride and ethylenediamine. Compared with the original lactic acid, the ethylenediamine-modified polylactic acid is more The hydrophilic effect is obvious, which is conducive to expanding the application scope of polylactic acid. The process of the experiment is simple, and the raw materials required for the experiment are easy to obtain. The experiment is environmentally friendly, pollution-free and valuable for the overall process of hydrophilic modification of polylactic acid fibers. |
