Abstract

The invention discloses a spinning manifold for manufacturing POY (pre-oriented yarn) and FDY (fully drawn yarn) composite fibers. The spinning manifold comprises a spinning manifold body (1), melt distribution pipes, metering pumps and spinning assemblies. The POY manufacturing spinning assemblies (2) and the FDY manufacturing spinning assemblies (3) are parallelly arranged side by side, each POY manufacturing spinning assembly (2) comprises two spinneret plates (4), and each FDY manufacturing spinning assembly (3) comprises two spinneret plates (5). The spinning manifold has the advantages that the POY and FDY composite yarn productivity and the POY and FDY composite yarn production efficiency can be guaranteed against being affected, so that the quality of obtained products is high, and the moisture absorption and the breathability of fabrics can be obviously improved.

Description

technical field [0001] The invention relates to a spinning box, in particular to a spinning box for producing POY and FDY composite fibers. Background technique [0002] The spinning box is composed of a melt distribution pipe, a metering pump, and a spinning assembly. The melt filtered by the filter enters the spinning box. The heating of the box body and the melt pipeline is heated by the guide steam generated by an electric heating furnace. There are 6 positions in the spinning box, and each position is equipped with a metering pump, which quantitatively presses the melt into the assembly, and is extruded through the fine holes of the spinneret to form a thin stream of melt. The role of the spinning box in the spinning forming process generally has the following aspects: [0003] 1. The melt is kept warm to the required temperature in the piping of the spinning box, and the temperature is kept uniform. [0004] 2. At a certain spinning speed, rely on the number of revo...
