SPINNING YARN'S HIGH SPEED DRAWING METHOD

摘要

This invention relates to the high speed drawing method of hank state acryl or nylon spinning yarn. The hank state spinning yarn is wound on a pair of rollers which are laid in a resisting pressure tank, and heated by steam until the internal temperature reaches 100--180≦̸C. At this temperature the space between two rollers is widened and the spinning yarn kis drawn. At this time the rotation of roller must be kept. After this process, steam is exhausted and the spinning yarn is relaxed and taken out by narrowing the space between two rollers.
