摘　　要：随着社会的发展进步,人们的安全防护意识不断升级,对防割类安全与防护用纺织品的需求与日俱增,研究其开发及应用具有重要的实际意义。文章以功能母粒和锦纶半光切片为原料,重点研究了功能母粒添加量对防切割改性锦纶6全牵伸丝分子量、力学性能和可纺性等的影响。结果表明:不同防切割功能母粒添加量对防切割改性锦纶6全牵伸丝的拉伸性能影响较大,在相同纺丝工艺条件下,随着防切割功能母粒添加量的增多,防切割改性锦纶6全牵伸丝的断裂强度逐渐减小,断裂伸长率逐渐增大,但对纤维的条干不匀率及染色均匀度影响不大。当添加量为7%时,制得的防切割改性锦纶6全牵伸丝防切割性能等级可达B级,其物性指标能满足使用要求且纺况良好。People pay ever more attention to safety protection with the progress in society.Their demand for cut-resistant safety and protective textiles is increasing day by day.Therefore,related research on its development and application has important practical significance.Taking functional masterbatch and semi-dull PA chips as raw materials,the paper studied the effect of the addition of functional masterbatch on the molecular weight,mechanical properties and spinnability of the cut-resistant modified nylon 6 fulldrawn yarn.Results showed that different amount of cut-resistant masterbatch has a great impact on the tensile properties of the anti-cutting modified nylon 6 full-drawn yarn.Under the same spinning process,the more addition of the anti-cutting masterbatch,the lower breaking strength of the cut-resistant modified nylon 6 full-drawn yarn.And the elongation at break gradually increases,but it has little effect on the unevenness of the fiber and the uniformity of dyeing.When the additive amount is 7%,the cut-resistant performance of the prepared anti-cutting modified nylon 6 full-drawn yarn can reach level B,and its physical properties can meet the requirements of use and the spinning condition is good.
