TEXTURED YARN AND METHOD AND APPARATUS FOR PRODUCING THE SAME |
摘要 |
A textured yarn suitable for weaving a fabric having an improved width shrinkage is provided by a simultaneous draw-texturing process of a partially oriented polyethylene terephthalate (PET) filament. During the draw-texturing process, the yarn delivered from a main heater is adjusted to maintain a yarn temperature not less than 80 DEG C. which corresponds to a glass transition temperature of PET prior to being introduced into a false twister, whereby both the crimpability and sonic velocity of the resulting yarn are improved. A fabric woven therefrom has a good bulkiness as well as a good resiliency. Further, according to the same principal, a textured yarn having crimp unevenness suitable for producing a fabric having a surface contour is provided by varying the yarn temperature prior to being introduced into the false twister in a range between 80 DEG C. and 160 DEG C. The latter yarn has no tight spots therein and results in a natural looking fabric. |
