Extended stretch manufacturing methods as well as stretching restore animal hair spun yarn of the hair fiber, stretching restore composite animal hair spun yarn, restore animal hair spun yarn, restore animal hair fabrics, extending telescopic hair fiber bundle, animal hair fiber bundle, stretching fixed animal hair fiber spun yarn and fabric

摘要

The object of the present invention, complicated and large-sized equipment, without the decrease in productivity, to provide a method of making a relatively easily extended telescopic hair fibers while suppressing the glare of the animal hair fiber surface It is in. In the method of manufacturing the extended telescopic hair fiber according to the present invention, firstly, swelling plasticized animal hair fiber bundle (5) is produced animal fiber bundle (1) is passed through the swelling plasticization treatment apparatus (30) that. And, then, in the side view, the upstream nip portion of the upstream nip roller pair (10) (10N) and upstream nip swelling plasticized animal hair fiber bundle between the downstream nip portion and (20N) of downstream nip roller pair (20) swelling plasticized animal hair fiber bundle in a state where the flowing S-shaped or reverse S-shape towards the downstream nip portion is drawn from.
