Development of cotton/colored cotton/spun silk blended yarn

To study the effect of blend ratio on the quality of yarn especially its tensile performance,a series of cotton /colored cotton / spun silk blended yarns in d ifferent blend ratio were spun by three fiber materials,naturally brown colored cotton,white cotton and spun silk fiber based on technological study of spinning processing.Properties of blended yarns with d ifferent blend ratio were tested.The results ind icated thatwith the spun silk content increasing,the tensile strength and elongation at break of yarn were significantly increased,and yarn physical performances such as yarn unevenness,thin and thick were improved significantly,while neps and hairiness of the yarn had no significant change.The add ition of spun silk can generally improve the performance of naturally colored cotton blended yarns.
