双曲线

In the influencing factors of yarn, the yarn of less diameter have lessfiloplume, as adding twist, the filoplume lessen, on the other hand, adding twist increases the tightness of fabric, make the filoplume of fabric moving back harder, aggravate theprickle to skin. The relationship between the prickle and twist is double curve.
