摘要:
In a partially oriented nylon feed yarn for drawtexturing, the filaments have high RV sheaths and low RV cores. Exceptional crimp development is achieved in the resulting textured yarn.
摘要:
High RV nylon 66 flat yarns having specified filament deniers afford superior fabric properties. The yarns also provide superior spinning performance.
摘要:
An improved partially-oriented nylon 66 (PON) spinning process and product are provided by increasing the molecular weightwell above the levels customary for apparel end uses.
摘要:
A polyester yarn having filaments with aperiodic varying shrinkage levels along their lengths, the filaments having within-filament and between-filament shrinkage C.V.'s of at least 10%. The yarn may be made by conventional melt spinning within a critical narrow range of spinning speeds wherein yarn shrinkage decreases rapidly with spinning speed. A greige fabric incorporating the yarn as filling is textured by shrinking the unrestrained fabric, then heating the fabric sufficiently to cause the yarn to elongate.
