Title:
CHEESE DYEING METHOD OF STRETCHABLE CONJUGATE YARN
Document Type and Number:
Japanese Patent JPH0559657
Kind Code:
A
Abstract:

PURPOSE: To provide a cheese dyeing method with small difference in stretch recovery between an inner layer and an outer layer of wound yarn layer of stretchable conjugate yarn and of producing previously dyed yarn in a short time and efficiently without requiring skill.

CONSTITUTION: In a cheese dyeing method wherein spandex yarn is used as core yarn, other yarn is arranged on the periphery of the core yarn to give stretchable conjugate yarn, which is wound on cheese to give a material to be dyed and the material is dyed, the cheese is made of a polypropylene starting softening at ≥60°C and a thermally shrinkable cheese having structure wherein plural fence-like members consisting of a pair of parallel longitudinal skeleton members and plural leap spring-like members bridging a pair of the longitudinal skeleton members are arranged in parallel in the peripheral direction is used. The conjugate yarn is wound on the thermally shrinkable cheese by slightly overfeeding the stretchable conjugate yarn at a feed speed based on a revolving speed of the thermally shrinkable cheese.
