Problems solved by technology

However, considering that the box is operated under high temperature conditions for a long time, in order to prevent heat loss in the box and maintain a constant high temperature in the box, a rock wool fiber insulation layer is generally installed outside the spinning box, and the insulation effect of rock wool fiber is extremely high. It is difficult to prevent the loss of heat in the cabinet, and it is poisonous and harmful to human monitoring, which does not meet the requirements of equipment energy saving and environmental protection
In addition, considering that the production of composite three-dimensional hollow crimped polyester affects its crimp mainly due to the difference in viscosity of the melt rather than the difference in temperature of the melt in the box, although the conventional composite box can meet the requirements for the production of composite three-dimensional hollow polyester staple fiber, but Because it is an independent main and auxiliary spinning box, and it is heated by two heat media with different temperatures, its processing is difficult, the processing cycle is long, the temperature accuracy is high, and the processing cost is high, which is difficult for general enterprises to accept.

Abstract

The invention relates to a double-component spinning box body and particularly relates to a single-temperature-control energy-saving type spinning box body used for producing composite fibers. The spinning box body comprises a box body and a spinning assembly, wherein the spinning assembly is fixedly arranged on the box body; the box body is internally provided with first metering pumps, second metering pumps and a heating medium; parts in the box body are immersed into the heating medium; the two ends of each first metering pump and each second metering pump are connected with a melt slurry feeding pipeline and a melt slurry discharging pipeline respectively; the melt slurry feeding pipelines are connected with slurry inlets of the first metering pumps and the second metering pumps on the box body respectively; the slurry inlets of the first metering pumps and the second metering pumps are connected with external melt filters; the melt slurry feeding pipelines are provided with melt pipeline needle type valves; and the melt slurry discharging pipelines are connected with an upper slurry inlet and a lower slurry outlet on the spinning assembly respectively. With the adoption of the single-temperature-control energy-saving type spinning box body, the quality of the product is improved, the production efficiency is improved and the labor intensity of workers is alleviated.

Description

technical field [0001] The invention relates to a bicomponent spinning box, in particular to a single temperature-controlled energy-saving spinning box for producing composite fibers. Background technique [0002] At present, with the intensification of competition in the chemical fiber market, more and more chemical fiber enterprises have become victims of the economic downturn. In order to survive in the fierce market competition and achieve long-term development, it is necessary to update equipment and technology, and develop market-competitive products with the application of new technologies and investment in new equipment, with excellent product performance and high product cost performance, Improve the market competitiveness of products. In recent years, the high-grade filling materials used in toys, sofas, mattresses, sound insulation and heat insulation materials on the market are mostly raw composite 3D coiled hollow polyester staple fibers, composite 3D coiled ho...
