Abstract
New poly(ethylene terephthalate) flat yarns and tows having physical properties and dyeability more akin to cellulose acetate than to conventional poly(ethylene terephthalate) flat yarns are prepared directly by spinning at speeds of about 4000 meters/minute. Among the useful physical properties are a modulus of 30 to 65, which is relatively unaffected by boiling, low boil-off shrinkage, no need for heat setting, low shrinkage tension, large crystal size, and low amorphous orientation which is measured by a value termed "amorphous modulus." The flat yarns may be used, e.g. in textile fabrics, without drawing, and may be modified, e.g. by air-jet texturing. The tows may be converted into staple fiber. <IMAGE>
