Problems solved by technology

After each round of silk is fully rolled after starting production, the machine must be stopped and manually doffed, which greatly reduces the production speed of the product. Due to the limitations of the machine and equipment (the production speed cannot be faster and the equipment occupies a large area), ITY Product production rate is slow

Embodiment Construction

[0019] Such as figure 2 , image 3 Shown, the inventive method comprises the following steps:

[0020] a. Spinning: Melt POY and FDY polyester melts onto POY and FDY spinneret 1 respectively, and simultaneously pull out POY and FDY filaments from the spinneret through POY and FDY silk paths respectively; where POY filaments are sprayed The spinneret positions on the spinneret are in one-to-one correspondence with the spinneret positions on the FDY spinneret. The initial temperature is 270-310°C.

[0021] b. Filament paralleling: the POY filaments and FDY filaments pulled out in step a respectively go through the oiling rack 2 and the oiling agent equalizer 3 for oiling and oiling agent equalization treatment, and then directly merge, and then pass through two stretching rollers 4 and two The network device 6 is paralleled, and the network device is arranged between the stretching roll and the stretching roll and between the stretching roll and the winder; the separating ro...

Abstract

The present invention discloses a composite fibre spinning process. It is characterized by that said spinning process can simultaneously produce polyester melt POY fibre and FDY fibre, and can directly conjugate them together by means of one-step operation, so that its production process is simple and its production cost is low.

Description

technical field [0001] The invention relates to a polyester melt POY and FDY composite yarn spinning method. Background technique [0002] Since polyester melt POY and FDY composite yarn products were developed from South Korea in the early 1990s, they have been used for various purposes and have become the mainstream products of polyester composite yarn. POY and FDY composite yarns belong to the combination of POY yarns (PRE-ORIENTED YARN, pre-oriented yarns) and FDY yarns (FULL DRAWN YARN, fully drawn yarns) with different shrinkage properties. They are different shrinkage fibers with soft touch. kind. Such as figure 1 As shown, the existing production method of POY and FDY composite yarns is to produce POY yarns and FDY yarns separately in the spinning process, and then use ITY (INTER-LACED YARN) (multi-network composite yarn) machinery to process them through compressed air. The network is compounded and is a two-step production method. In this inevitable multi-proce...
