RAYON FASCIATED SPUN YARN AND RAYON/WOOL FASCIATED SPUN YARN BY AIR FALSE TWISTING METHOD

摘要

PURPOSE:To obtain fasciated spun yarn having crispiness imparted to pliancy with drapeability of rayon fiber and feel of woolen fiber by spinning a fiber bundle of respective rayon fiber or further with woolen fiber using an air false twisting type spinning apparatus. CONSTITUTION:Fasciated spun yarn (Y) of rayon or rayon and wool sufficiently obtained by forming a fiber bundle 2 of the rayon fiber having =200mm maximum fiber length, =55mm average fiber length and =5 denier single filament size or mixed fiber composed of 20-80wt.% aforementioned rayon fiber and 80-20wt.% woolen fiber having 140-240mm maximum fiber length and =55mm average fiber length into the shape of a fleece using a drafting mechanism composed of a back roller pair 3, a middle roller pair 5 and a front roller pair 6 and false twist spinning the resultant fleece with air jet nozzles 7 and 9.
