Problems solved by technology

But the improvement of these existing technologies to this production, that is, the one-step method is mainly the winding stage, and the pre-spinning step adopts two spinning boxes to produce different polyester filaments respectively, and has not realized real simultaneous production. Spinning box one-step method, not to mention the process integration of colored composite polyester yarn

Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 The production process flow diagram of the one-step method shown in the production of colored composite polyester yarn, the specific described method comprises the following steps:

[0020] a. The polyester chips in the chip silo 1 are transported to the chip dryer 2 for drying, and then transported to the screw extruder 3 to be heated and melted into a melt.

[0021] The polyester used in the present invention is polyethylene terephthalate (PET for short), and the PET raw material is vibrated and screened to remove powder and particles with inconsistent particle sizes, and the sliced ​​raw material that meets the requirements is transported to the sliced ​​bin 1 for standby. Before melting, the slices are also sent to the dryer 2 for drying to remove moisture in the slices. The dried chips enter the screw extruder 3 for heating and melting....

Abstract

The invention discloses a method for producing a color composite polyester yarn through one step. Spinning positions are utilized to divide different areas, and the synchronous different-path spinning of pre-oriented yarns (POY) and fully-drawn yarns (FDY) and strand combined yarn networking are compounded together, so that four processing links of stock solution coloring, spinning, drawing and networking are completed through a one-step method. The production technological process is short, the production efficiency is high, energy consumption and loss are small, pollutant discharge is reduced, and the method is ecological and environmental-friendly.

Description

technical field [0001] The invention relates to a melt spinning method, in particular to a method for producing colored composite polyester yarn in one step. Background technique [0002] The technology of white mixed fiber composite polyester yarn is relatively mature, but it is mostly produced by two-step process, which has long process flow, low production efficiency, large energy consumption and loss, and to make colored fabrics, it is necessary to dye the fabric after weaving. Subsequent deep processing links are seriously polluted and not environmentally friendly. At present, some improvements have been made to this technology, such as the equipment and method for one-step production of chemical fiber polyester composite yarn disclosed in the patent application document CN102618983A, and the one-step process 24 head / position multi-different mixed fiber composite fiber spinning disclosed in the patent document CN202265627U Winding joint production equipment, etc. But ...
