Abstract

The invention discloses a method for producing POY varieties by FDY equipment. A technological process of the FDY equipment includes the steps that a yarn bundle sequentially passes through a yarn guide, a first yarn guide hook, a pre-interlacing device, a yarn dividing rod, a first drawing roller, a second drawing roller, a third drawing roller, a fourth drawing roller and a main interlacing device downwards and then is wound and formed through a winding device to obtain FDY finished products. The method for producing the POY varieties by the FDY equipment includes the steps that step one, bases are arranged at the positions, corresponding to the pre-interlacing device and the yarn dividing rod, of the FDY equipment, the pre-interlacing device and the yarn dividing rod are located on thebases respectively, and the center line of the yarn bundle located above the first yarn guide hook and the center line of the yarn bundle located below the pre-interlacing device are not located on the same straight line. The provided method for producing the POY varieties by the FDY equipment is high in POY full-package rate.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a method for producing POY varieties with FDY equipment. Background technique [0002] Based on changes in market conditions, when FDY product prices are sluggish and profitability declines, sometimes even losses occur. At this time, FDY production equipment and technical processes can be transformed to achieve the purpose of producing POY products, so as to achieve greater profits. economic benefits. According to the prior art, a method and device for POY spinning by FDY spinning device are disclosed on the website of the State Intellectual Property Office, the patent number is CN102660786B, and the full volume rate of POY is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above defects of the prior art and provide a method for producing POY varieties with FDY equipment with high POY full volume rate. ...
