Abstract:
A twisting method for a yarn strand includes passing the yarn to a pin where the yarn is wrapped no more than 360. degree. about the pin and where the pin intersects the yarn path at an angle of approximately between 90. degree. and 100. degree. , the yarn may be previously heated and cooled upstream of the twister to impart texture to a thermoplastic yarn; the pin twister may be flexible and may be vibrated to induce random variations in the amount of twist imparted to the yarn wrapped around the pin; the yarn downstream of the false twisted pin may be passed directly to a fabric forming machine for incorporation of the yarn into a fabric; the pin may be used to impart twist to a moving yarn in a variety of applications.
