Title:
CONJUGATE ELASTIC YARN AND METHOD OF PRODUCING SAME
Document Type and Number:
Japanese Patent JPS51136951
Kind Code:
A
Abstract:
A composite yarn, which is bulky when relaxed and elongates to at least 100 percent greater length under tension, with quick recovery of the relaxed condition when tension is removed, is composed of uncrimped elastic yarn and at least five relatively inelastic continuous filaments entangled about the elastic yarn to provide protection and desirable textile properties. The composite yarn can be made at unusually high speeds by entangling the relatively inelastic filaments about stretched elastic yarn with jets of high velocity fluid impinged at an angle of 90 DEG +/-45 DEG to the yarn axis, using a filament feed rate which avoids formation of filament loops in the stretched yarn. Examples illustrate combining spandex elastic yarn at 4X stretch with nylon filaments at zero percent overfeed, when using feed rates of up to 789 yards per minute.
