Technical Analysis of Hemp/Cationic Modified Cotton Blended Yarn
In order to solve the problems of poor spinnability of hemp fiber,such as high lignin and gum content,low fiber coarseness,low uniformity and high fiber length dispersion,the pretreatment process of health preserving of hemp fiber was analyzed and studied,the cationic modification of cotton fiber was carried out.The technical route and main technology of hemp blended yarn were analyzed.The research shows that the performance index of hemp fiber after optimized curing pretreatment can meet the demand of back spinning process,high quality hemp/cationic modified cotton blended yarn was successfully produced on the basis of ring spinning equi pment,and the yarn strength and evenness were significantly improved by compact Siro spinning process.
