The method of Confucius ticketing fiber axis of the single component using a capillary cooling unit

摘要

The invention having been melted, extruded polyester polymer of a single component in a hollow spinneret and then cooling the solidified by hollow spontaneous In the manufacture of crimped fibers, the spinning immediately after (normally, the cooling processing before) only the cooling air on one side of the spun yarn to by spraying causes the differences in the degree of orientation and crystallization in size on each side portion of the spun yarn by character so that these differences cause a difference in thermal shrinkage properties being a method for producing such ticketing layering expression.
