Problems solved by technology

The existing full-dull modified polyester has disadvantages and difficulties such as high spinning production consumption, high hardware conditions for DTY stretching, easy to produce color stripes in shake socks dyeing, and high requirements for subsequent fabrics. Therefore, it is relatively scarce in the market and cannot meet customer needs.

Embodiment Construction

[0016] The present invention will be further described below with regard to specific embodiment:

[0017] A production method of full-dull modified polyester, comprising the following steps: the masterbatch is transported to a drying system for crystallization and drying, and then passes through a masterbatch high-level silo, screw melt extrusion, a masterbatch metering pump, a melt dynamic mixer, After the melt static mixer enters the spinning box, at the same time, the polyester melt is transported through the pipeline, the booster pump enters the melt cooler to cool, and then is transported into the spinning box through the pipeline to polymerize with the masterbatch melt. Then go through the metering pump, spinneret, ring air cooling, nozzle oiling, wire guide, pre-network, GR1, GR2 winding forming, finished product inspection, and then pack into the warehouse. alcohol. Specifically, a melt injection system is designed and added in front of the spinning box of the POY spi...

Abstract

The invention discloses a production method for complete extinction modified polyester. The production method comprises the following steps: conveying master batch to a drying system for crystal drying, feeding through a master batch high-level cabin, a screw rod melting extrusion machine, a master batch metering pump, a melt dynamic mixer and a melt static mixer in sequence, feeding into a spinning manifold, and performing a polymerization reaction on polyester melt in the spinning manifold, wherein the polyester melt is cooled by a melt cooler; feeding through a metering pump and a spinneret plate, performing annular air-blowing cooling, and feeding oil through a nozzle, feeding through a wire guide and a pre-network, performing GR1 and GR2 coiling molding, inspecting a finished product, and packaging and storing in a warehouse in sequence. By adoption of the production method, production situations can be relatively stable, a product is excellent in appearance and high in dyeing property, and later weaving can be performed smoothly.

Description

[0001] Technical field: [0002] The invention relates to polyester production technology, in particular to a production method of full-dull modified polyester. [0003] Background technique: [0004] Since the "Eleventh Five-Year Plan", my country's chemical fiber industry has been in a state of rapid development, and the output of chemical fiber has grown rapidly. In recent years, the situation of overcapacity in the domestic chemical fiber industry has become prominent. Against the backdrop of the unfavorable situation in the global chemical fiber market, raw material costs account for 87% of the industry's production costs and oil prices are high, the ability of China's chemical fiber industry to continue to absorb oil price pressures and transmit cost pressures downstream has weakened. To overcome difficulties and remain invincible in the fierce market competition, we must take the road of technological innovation and rely on product differentiation and functionalization t...
