Production practice of knitted yarn with wicking anti-pilling fiber /PTT /wool

The paper describes the properties of raw material used in 14. 8 tex knitted yarn with wicking anti-pilling fiber / PTT / wool( 65 /20 /15), the key technical points of each process and parameters were also disscussed. According to the characteristics of raw performance,combining with practical situations,a spinning process route was selected rationally,raw material was pretreated before spinning,more opening,less noil should be adopted in opening and cleaning process,tight gauge,strong carding were introduced in carding process,rational distribution of drafting was chosen in drawing process,suitable roving twist factor was chosen,low speed and strengthening fiber controlling should be adopted to improve yarn evenness. Only by appropriate process parameters as well as adopting appropriate technical,smooth production of yarn can be ensured and achieve the design requirement.
