Abstract

The invention relates to a POY (polyester pre-oriented yarn) spinning method and device by using a FDY (fully drawn yarn) spinning device. The POY spinning method is realized by using the FDY spinning device, wherein the FDY spinning device comprises a box body, a cross air blasting window, a chimney, a first hot roll, a second godet and a winding head. When the POY spinning is preceded, an oil tanker of the original FDY spinning device is stopped using, an oil nozzle is additionally arranged above the chimney for feeding oil, and a guide wire hook and combtype wire-dividing device of the first hot roll are provided with extension rods for moving outwards in a pre-network so as to move the spinning central line outwards; meanwhile, a second hot roll of the original FDY spinning device is stopped using, the first hot roll and the second godet are reserved, the filament bundling passes through the first hot roll for one time and winds 4-5 circles on the second godet for further moving the spinning central line outwards, and then enters into a wiring head for realizing winding. The method provided by the invention can produce high-quality POY on hot-roll type FDY equipment with the advantages of less transformation investment, simple method and fast transformation speed, thus realizing flexible production between the FDY and POY products at any time.

Description

A kind of method and apparatus that carries out the POY spinning by the FDY device for spinning

Technical field

The method and apparatus of POY is produced in the repacking that the present invention relates to a kind of FDY device.

Background technology

For adapting to market changeable, domestic existing many producers have realized on the FDY production line, producing the technological transformation of POY product, and obtain good effect.Three kinds of methods are generally arranged: first method is utilized former FDY device, Direct Production POY; Second method is to remove the FDY hot-rolling, increases draw-off godet; The third method is to utilize the FDY hot-rolling, but first hot-rolling is overhanging concordant with second hot-rolling etc.

Above-mentioned three kinds of FDY devices are produced the technological transformation of POY product, and the first method production stability is poor, generally are difficult to successfully, and second kind, the third method retrofit work amount and drop into greatlyyer are unfavorable for the FDY that resumes production.

Chinese invention patent application (application number: 03112239.6 applying date: 2003-05-30) disclose a kind of processing method of carrying out islands-in-sea type fibre POY production based on islands-in-sea type fibre FDY production equipment; Be to be raw material with the section of general fibre grade polyester chip and water-soluble polyester; But the melt extruded of respectively hang oneself drying machine drying, screw extruder becomes the polyester fondant of spinning; And filter the spinning pump accurate measurement of afterwards delivering to the conventional polyester melt by the melt distributing pipe, be evenly distributed to the composite component that is incubated by spinning manifold accordingly by each isometric melt manifold; Two kinds of polyester fondants that in composite component, mix spray from assembly; Oil through spinning shaft through lateral blowing device cooling forming, oil nozzle; And preparatory the nozzle of interlace blows net and is drawn to first hot-rolling, second hot-rolling, and tow is rolled into islands-in-sea type fibre POY spinning cake by winding head after through second hot-rolling.

But above-mentioned FDY device fabrication POY exists first godet system and second godet system not on same vertical plane, and FDY spinning centre-to-centre spacing and coiling centre-to-centre spacing is not in the first-class problem of same vertical plane.

Summary of the invention

In order to solve above-mentioned technical problem; An object of the present invention is to provide a kind of method of carrying out the POY spinning by the FDY device for spinning; The POY that this method is produced on the FDY device transforms less investment, normally operation for a long time after the transformation; Product quality reaches the product level of POY production line, and is easy to flexibility conversion between FDY to POY, POY to FDY.Another one purpose of the present invention provides the POY device for spinning of being transformed by the FDY device for spinning.

In order to realize first above-mentioned purpose, the technical scheme below the present invention has adopted:

A kind of method of carrying out the POY spinning by the FDY device for spinning; Described FDY device for spinning comprises casing, quenching air window, path, first hot-rolling, second godet roller and winding head; When carrying out the POY spinning, the oil tanker of former FDY device for spinning is stopped using, and above the path, sets up oil nozzle and oils; And with before first hot-rolling in advance under the network traveller and comb type divide a silk device to move outward through extension bar is set, the spinning center line is moved outward; Simultaneously, second hot-rolling of former FDY device for spinning is stopped using, and keeps first hot-rolling and second godet roller, tow single pass first hot-rolling, and move the spinning center line around 4 ~ 5 circles are further outer at second godet roller, tow gets into described winding head then and realizes coiling.

In order to realize second above-mentioned purpose, the technical scheme below the present invention has adopted:

POY device for spinning by the transformation of FDY device for spinning; Described FDY device for spinning comprises casing, quenching air window, path, first hot-rolling, second godet roller and winding head; The oil tanker of the inactive former FDY device for spinning of this POY device for spinning; Above the path, set up oil nozzle and oil, and divide a silk device to move outward on traveller and comb type under the preparatory network before first hot-rolling, the spinning center line is moved outward through extension bar is set; Simultaneously, second hot-rolling of former FDY device for spinning is stopped using, and keeps first hot-rolling and second godet roller, tow single pass first hot-rolling, and move the spinning center line around 4 ~ 5 circles are further outer at second godet roller, tow gets into described winding head then and realizes coiling.

The present invention efficiently solves hot-rolling formula FDY device fabrication POY and exists first godet system and second godet system not on same vertical plane; FDY spinning centre-to-centre spacing and coiling centre-to-centre spacing is not in the first-class problem of same vertical plane; Realized on hot-rolling formula FDY equipment, producing high-quality POY, transformed less investment, method is simple; Transformation speed is fast, realizes flexible production between FDY, POY product at any time.In actual production, the range of product size of being produced can be controlled at (75 ~ 200) dtex/ (36 ~ 48) F.
