Embodiment 1

[0024] In the production method of low shrinkage polyester composite fiber described in this example, the semi-dull polyester melt is transported to the cooler through a booster pump and then enters the interior of the static mixer; then the semi-dull polyester melt is melted through a melt distributor The melt is transported to the spinning box, and the semi-dull polyester melt is extruded to the POY spinneret and FDY spinneret by a metering pump. The POY fibers from the POY spinneret are cooled by side blowing, and then oiled through the oil nozzle in turn. , yarn guide, pre-network, yarn guide, the FDY fiber coming out of the FDY spinneret is cooled by side blowing, and then oiled through the oil nozzle, yarn guide, pre-network, GR1 hot roller, POY coming out of the yarn guide The fiber and the FDY fiber coming out of the GR1 hot roll enter the ply comb-shaped yarn guide together, and then pass through the godet, the intermediate network, the GR2 hot roll, the main network, ...

Abstract

The present invention relates to the field of polyester fiber production equipment, and especially discloses a production method of low-shrinkage rate dacron complex fibers. Semidull polyester melts enter into a static mixer, are then conveyed into a spinning manifold through a melt distributor, and are extruded onto a POY spinneret and an FDY spinneret; POY fibers coming out of the POY spinneret are cooled by cross air blow and oiled by an oil nozzle, pass a yarn guide, a pre-network and another yarn guide; FDY fibers coming out of the FDY spinneret are cooled by cross air blow and oiled by an oil nozzle, pass a yarn guide, a pre-network and a GR1 hot roller; and the POY fibers coming out of the yarn guide and the FDY fibers coming out of the GR1 hot roller enter into a stranding comb-shaped yarn guide together, and then pass a yarn guide disc, an intermediate network, a GR2 hot roller and a main network, thus to be rolled for shaping. According to the production method, the obtained fibers are different in boiling water shrinkage, and thus a shell fabric is good in velvet feeling, soft in hand feeling, firm, anti-wrinkle and wear-resisting.

Description

technical field [0001] The invention relates to the field of polyester fiber production equipment, in particular to a production method of low-shrinkage polyester composite fiber. Background technique [0002] The added value of the product in the existing fiber product production is low, thus making the competitiveness of the enterprise poor. Contents of the invention [0003] The purpose of the present invention is to provide a method for producing low-shrinkage polyester composite fibers in order to solve the deficiencies of the above-mentioned technologies. The obtained fibers have different shrinkage in boiling water, so that the fabric has a strong velvet feel, soft hand feeling, and great skin affinity; but Without losing fastness, it can resist wrinkle and wear, and has good drapability. [0004] In order to achieve the above-mentioned purpose, the production method of the low-shrinkage polyester composite fiber designed by the present invention, the semi-dull pol...
