Abstract

The invention discloses a composite special-shaped spinning device for producing a high-brightness high-resilience terylene BCF (Bulked Continuous Filament). The composite special-shaped spinning device comprises a shell, a filter screen, a spinning plate, a washer and a fastening piece, wherein the spinning plate and the filter screen are fixed in the shell through the fastener; the washer is embedded into the melt inlet of the shell; and the spinning plate is provided with a spinning hole. The composite special-shaped spinning device is characterized in that: the spinning hole is trefoiled; the width of the leaf top of each leaf of a trefoil is smaller than that of each leaf root; both sides of each leaf intersect with each other on an elongation line, so that an included angle is formed; the included angle is 10-11 degrees; and the length of each leaf is 0.8-1.1 millimeters. The spinning device is easy and convenient to clean, assemble and produce, and the product terylene BCF has the advantage of high bulkiness and the characteristic of high brightness. A fabric business carpet has high covering performance, bright color and luster, bright color and high resilience, and a high-grade novel fiber material is provided for the business carpet.

Description

technical field

[0001] The invention relates to an equipment device for producing novel chemical fiber materials, in particular to a BCF composite special-shaped spinning device for producing high-brightness and high-resilience polyester. Background technique

[0002] BCF (Continuous Bulked Filament) has the characteristics of good bulkiness, high resilience, stable three-dimensional crimping, and soft touch. It has been widely used in carpets, car seat cushions and decorative fabrics.

[0003] At present, the modified polyester BCF has the advantages of low price, high strength, easy dyeing, and recyclability, but compared with the expensive nylon BCF, its brightness and resilience are quite different.

[0004] The authorized invention patent 200810063476.4 and the published invention patent 201010153396.5 are only for the preparation of easy-to-dye and ultra-fine polyester BCF. The spinneret micropores used are all three-lobed (Y) shaped, and the brightness of the produced...
