Under the condition of a certain spinning speed, the principle of selecting the stretching ratio is as follows: greater than the natural stretch multiple and less than the breaking stretch multiple. The larger the draft multiple of the precursor is, the larger the breaking strength is, and the smaller the breaking elongation is; the smaller the strand draft ratio, the smaller the breaking strength and the larger the breaking elongation. When the draft multiple is more than 3.5 times, broken filaments and broken filaments are generated.
