Abstract:In order to improve the breaking strength of raw yarn and meet the tear and burst strength of finished fabric，the effects of spinning twist factor，fiber length，fiber linear density and initial modulus of viscose fiber on the yarn strength of viscose/cotton blended yarn are discussed.Through parameter optimization and cotton assorting cost calculation，high wet modulus viscose fiber with matching ratio of 60% and linear density of 1.33 dtex，and high-quality Brazilian medium cotton with matching ratio of 40% are selected as spinning materials.The result of parameter optimization and cotton assorting cost calculation are used to spin the yarn for fabric of R/CJ 60/40 18.2×L/R 55/45 38.9 299×268 160 1/1.The key points of each spinning process are described in detail.It is pointed out that the twist factor of viscose/cotton blended yarn needs to be set a larger yarn density than that of viscose yarn and pure cotton yarn with the same yarn density，which the yarn strength can be improved.The improvement of cotton fiber length and length uniformity on yarn strength is not obvious.The uniform distribution of fibers in the section of yarn is beneficial to improve yarn strength.High wet modulus viscose with a suitable linear density can increase yarn strength of blended yarn and improve elongation at break significantly.
