Abstract

The invention relates to a multi-differential shrinkage combined filament yarn preparation device and method. The device comprises a first spinning assembly, a second spinning assembly, a first godet, a second godet, a third godet, a four godet, a first heat roller, a second heat roller, a third heat roller, a fourth heat roller, a steering gear, a setting heat roller, a humidifying device, a doubling device, a wire stitching machine and a winding roller. The preparation method comprises the following steps of spinning with a first spinning solution and splitting into first pre-oriented yarns and second pre-oriented yarns; spinning with a second spinning solution and splitting into first fully drawn yarns and second fully drawn yarns; allowing the second pre-oriented yarns and the second fully drawn yarns to pass through the humidifying device and the setting heat roller and then pass through the doubling device, the wire stitching machine and the winding roller together with the first pre-oriented yarns and the first fully drawn yarns to obtain multi-differential shrinkage combined filament yarns. The multi-differential shrinkage combined filament yarn prepared by the invention has a multi-crimping three-dimensional effect, has a plump appearance and hand feeling, flexible adjustment of multi-differential shrinkage effect of combined filament yarns, and improvement on processing stability.

Description

technical field [0001] The invention belongs to the technical field of different shrinkage mixed fiber spinning, and in particular relates to a preparation device and method of multiple different shrinkage mixed fiber yarns. Background technique [0002] POY (pre-oriented yarn) / FDY (full drawn yarn) different shrinkage mixed fiber yarn is a kind of differentiated filament yarn formed by combining POY filament and FDY filament together. Due to the thermal shrinkage rate of POY and FDY fibers Different, after heat treatment, the monofilament with a large heat shrinkage rate shrinks into a core yarn, and the filament with a small heat shrinkage rate is crimped on the surface of the mixed fiber yarn, thus overcoming the sticky and fluffy feel of ordinary filament products to a certain extent. Low disadvantages, can be widely used in wool-like, linen-like, cotton-like, spinning and other products. The different shrinkage mixed fiber yarn currently produced is made by compounding...
