Problems solved by technology

After the melt is extruded from the spinneret, it is generally cooled by water cooling or air cooling. In the past few years, the technology of cooling and forming the filaments was mainly the side blowing cooling technology, but the fiber unevenness of the produced polyester fibers is low. , and the required cooling air volume is large, which increases the energy consumption and cost increase in the production process, and also limits the number of holes in the spinneret

Embodiment 1

[0040] In the production method of the high F soft velvet cotton-like fiber described in this example, the polyester is put into the final polymerization tank and passed through the melt distributor, and then the booster pump is used to transport the melt through the melt cooler and then enters the static mixer Then, after passing through the melt distributing valve, it enters the spinning box, extrudes the melt by a metering pump, spins on the spinning assembly, uses a ring blower to cool and form, and finally goes through oiling, spinning Winding, winding, quality inspection, and packaging are carried out after the tunnel, network device, GR1 godet, and GR2 godet; the viscosity of the melt is 0.646dl / g, and the outlet temperature of the melt cooler is controlled at 284°C .

[0041] In the selection of the spinneret, the analysis and design were carried out from the perspective of improving the dyeing. It is necessary to consider that the number of 192F holes must meet the re...

Abstract

The invention relates to the field of terylene production spinning in light and textile industry, in particular to a production method of high-F soft plush cotton-imitated fiber. According to the method, polyester is put into a polymerization final polycondensation kettle and then passes through a melt distributor, melts are conveyed by a boosting pump and then enter a static mixer after passing through a melt cooler, next, the melts enter a spinning box after passing through a melt distributing valve, the melts are extruded by a metering pump, the spinning is carried out on a spinning assembly, an annular blowing air tube is adopted for cooling forming, and finally, winding, spooling, quality inspection and packaging are carried out sequentially through an oiling device, a spinning channel, a spooling device, a GR1 draw-off godet and a GR2 draw-off godet, wherein the viscosity of the melts is 0.643d1 / g to 0.650d1 / g, and the outlet temperature of a melt cooler is controlled to be 280 DEG C to 286 DEG C. Cotton-imitated fiber, silk tows and fabric produced by the method have the hand feeling of cotton yarn effect.

Description

technical field [0001] The invention relates to the field of polyester production and spinning in light industry textiles, in particular to a production method of high-F soft velvet imitation cotton fiber. Background technique [0002] For a long time, the differentiation technology of polyester fiber has been the focus of chemical fiber enterprises. After the melt is extruded from the spinneret, it is generally cooled by water cooling or air cooling. In the past few years, the technology of cooling and forming the filaments was mainly the side blowing cooling technology, but the fiber unevenness of the produced polyester fibers is low. , and the required cooling air volume is large, which increases the energy consumption and cost increase in the production process, and also limits the number of holes in the spinneret. Contents of the invention [0003] The purpose of the present invention is to provide a kind of tow cooling sufficiently in order to solve above-mentioned ...
