Production Practice of C/Shutansi 60/40 29.16 tex+70 D Siro Spinning Core-spun Yarn
In order to give full play to the advantages of Shutansi fiber and spin Shutansi fiber yarns well,the cotton assorting,blending and drawing mode and spinning process of C/Shutansi 60/40 29.16 tex+70 D Siro spinning core-spun yarn are introduced,the process parameters set-ting and control requirements of opening,carding,drawing,roving,spinning and winding are an-alyzed.It is pointed out that the Shutansi fibers have poor straightness,good resilience,high rolling index and poor spinnability alone,and must be mixed with good spinnability fiber to roll and strip smoothly.The yarn blending ratio is accurate and stable,and the drafting process can prevent the increase of small nubs,yarn nubs and neps caused by improper control of Shutansi retraction,so as to ensure the yarn quality and make the fabric have good resilience and weara-bility.
