Problems solved by technology

[0007] Since the production of sea-island fiber POY and sea-island fiber FDY uses two different equipment and processing methods, it is undoubtedly difficult for manufacturers to use one set of equipment for the production of sea-island fiber POY and another set of equipment for the production of sea-island fiber FDY. Need to increase a lot of capital investment, resulting in increased production costs and products that lack competitiveness

Embodiment Construction

[0025] see figure 1 Shown, a kind of sea-island fiber FDY production equipment of the present invention carries out the processing method of sea-island fiber POY production, it comprises;

[0026] Ordinary fiber-grade polyester chips are used as the first raw material A. After the raw material A is dried by the first dryer 11, it enters the first screw extruder 21 and is melted and extruded by the first screw extruder 21 to become a spinnable fiber. The polyester melt from the first screw extruder 21 is measured by the measuring head to ensure that the spinning temperature is 285-295°C, and after filtering, it is sent to the ordinary polyester melt by the melt distribution pipe. The spinning metering pump accurately measures, and the melt manifolds of equal length are evenly distributed to the corresponding composite components that are insulated by the spinning box 3;

[0027] Water-soluble polyester chips are used as the second raw material B. After the raw material B is dr...

Abstract

POY sea-island fibers can be produced by FDY sea-island apparatus from common fiber-grade polyester slices and aqueous soluble polyester slices as raw materials, which are respectively dried via a drying device, melted and injected via a screw injector to form spinnable molten of polyester, filtered, fed to a molten polyester distributor with metering pump for spinning, metered accurately, distributed to correspondent thermal composite assemblies with thermal spinning casings via molten feeding manifolds of with equal lengths, mixed there and sprayed out, laterally blown to cool, oil supplied via spinning channels and pre-network nozzles, and led to go through first and second heating rollers to be winded and form silk cakes of POY sea-island fibers. Both of the fibers can be produced in one apparatus to save investment.

Description

technical field [0001] The invention belongs to the technical field of chemical fiber polyester processing, and in particular relates to a processing method for producing sea-island fiber POY based on sea-island fiber FDY production equipment. Background technique [0002] Sea-island fiber is a kind of composite fiber. After post-processing and finishing, the composite fiber can be the thinnest commercialized fiber in the world. It is an ideal raw material for producing high-grade clothing fabrics, high-grade decorative cloths, and high-grade wiping materials. The sea-island fiber currently known in the industry is made of ordinary fiber-grade polyester chips (PET) as the island component, and a special polyester chip (ie, water-soluble polyester chip ES-CHIP) as the sea component. , Extruded and melted into the spinning metering pump with spinning box insulation for precise metering and extrusion, distributed to each composite spinning assembly, evenly distributed island co...
