Abstract
PURPOSE: To control the repeating periodic length and the ratio between the length of thin and thick parts freely, by drawing an undrawn polyethylene terephthalate yarn under specific conditions.
CONSTITUTION: An undrawn yarn consisting of polyethylene terephthalate, and having a double refraction of 15W80×10-3 is drawn under such conditions as to satisfy the formulas I and II [R is the ratio between the peripheral speeds of a draw roll 6 and a feed roll 4; T is the maximum temperature (°C) to heat the undrawn yarn before the drawing point (the temperature of a snapper pin 5); E is the elongation (%) of the undrawn yarn under a constant stress; L is the distance (mm) between the yarn take-off point A and the yarn introductory point B of the draw roll 6; l is the periodic pattern length (mm) of the aimed thick and thin yarn; γb (%) is the ratio between the yarn length of the thick part and one pattern length of the aimed thick and thin yarn], at a T of 70W90°C a γb of 25W60mm and an l of 100W400mm.
