Device used for producing three-component skin core type fiber

Abstract

The invention relates to a device used for producing three-component skin core type fibers, comprising a gland, a first inner sand cup, a second inner sand cup, a first distribution plate, a second distribution plate, a third distribution plate, a fourth distribution plate and a spinneret plate, wherein three melts enter from three melt inlets, then enter into the spinneret plate after passing through the four distribution plates and are extruded from micropores on the spinneret plate, and each wire beam is respectively composed of three different components, namely inner component, medium component and outer component. The panel of each distribution plate is provided with flow channels, and melts comprising different components are distributed by different flow channels, thus fibers with different sectional shapes are formed. The spinning assembly provided by the invention is in a cup-type structure that the lower part is wide and the upper part is compact, and the melts extruded by each micropore on the spinneret plate are in the same pressure and flow distribution. In the invention, the types of the melts are changed or colour master batches in different colours are added to produce different three-component fibers or anti-counterfeit fibers, and the anti-counterfeiting effect is obviously improved compared with single-component fibers and bi-component composite fibers.

Description

technical field [0001] The invention belongs to the field of chemical fiber spinning processing equipment, in particular to a device for producing three-component sheath-core fibers. Background technique [0002] The devices disclosed in the prior art for the manufacture of multicomponent fibers are mostly used to manufacture bicomponent fibers, such as the bicomponent orange segmental fibers spun by polyester, brocade and orange petal-shaped composite spinning components, polyester Nylon-side-by-side composite spinning packs spin two-component parallel-side-by-side or equal-section side-by-side bi-component composite fibers, but the research on three-component sheath-core composite spinning packs is rare. In the multi-component composite spinning device, the melts of each component are distributed differently through the distribution plate, and finally the composite fibers with different cross-sectional shapes are spun, so the distribution plate is a key part of the spinnin...
