Description
Summary:Three POY yarns of 80/100, 80/48, and 80/34 denier/filament are textured with four variables at five levels. The Box-Hunter statistical experimental design is used to produce thirty-six samples in each case. The effects of texturing variables—draw ratio, disc surface speed to yam speed ratio (D/Y ratio), first heater temperature and heater contact time on tensile properties, crimp characteristics, dye uptake, broken filaments, and tight spots—are studied. First heater temperature and draw ratio have a significant influence oh tensile, crimp, and dyeing properties. With increased D/Y ratio, broken filaments decrease but tight spots increase. A proper selection of the D/Y ratio gives acceptable levels of broken filaments and tight spots.
