Effects of Twist on PSA (Polysulfonamide) Yarn Properties

摘要：

Several kinds of PSA (polysulfonamide) yarns with different twists were designed and produced;the tensile property and appearance quality of these yarns were tested and analyzed.It can be found that with the raising of TM (twist multiplier),the yarn strength increases firstly and then decreases,while the yarn evenness is in a contrary trend and the yarn hairiness declines steadily.When the TM reaches 240,the strength of the yarn comes to maximum.
