Document Type and Number:
Japanese Patent JP2002004143
Kind Code:
A
Abstract:
To provide a method for manufacturing nylon staple yarns having crimps excellent in compression resistance or nylon straight staple yarns excellent in straightness, efficiently at low cost.
The method for manufacturing nylon raw cotton having crimps is carried out as follows: nylon tows obtained by melt spinning and solidified by cooling are stretched; and subsequently, they are crimped and at the same time heat set with superheated steam to hold crimps. Or, the method for manufacturing nylon straight raw cotton is carried out as follows: nylon tows obtained by melt spinning and solidified by cooling are stretched; and subsequently, they are heat set with superheated steam to improve the straightness of the raw cotton.
