【Abstract】 Taking the T/C 13tex yarn as the case, a series of experiments were carried out. The experimental data were analysed by the t test method and the ordinal sum method, to see if it is feasible to eliminate the pre drawing process of polyester in the blending of polyester/cotton. The problem has also been analysed from the stand point of the technical process. The results show that eliminating pre drawing do not affect much on the quality of the yarn.更多还原
