METHOD FOR HEATING CRIMPED FIBERS AND PRODUCT THEREOF

摘要

26 TITLE Method for Heating Crimped Fibers and Product Thereof A method of producing crimped tow by continuously feeding a tow against an adjustable counter pressure means; the tow is maintained at an average predetermined thickness and steam enters the chamber and is exhausted from the chamber in a manner to provide uniform heating of the tow to provide a fiber that is uniformly annealed as determined by measuring light reflectance for yarn dyed with a structural sensitive Milling Blue "B" dye or shrinkage uniformity determined by thermal analysis. 26
