Abstract

The invention discloses a preparation method of an HOY spring wire. The method comprises the steps that 1, polyester chips are pretreated; 2, the polyester chips are melted into a spinning fluid through a screw extrusion machine; 3, the spinning fluid is pressed into a spinning component and sprayed out through a spinneret plate, and tows are formed in a spinning window; 4, the tows are subjected to cross air cooling, oiling, bundling and antistatic treatment and then further cooled through a spinning channel, wherein the cross air blasting speed is 0.5-0.9 m / s; 5, the cooled tows pass through a pre-interlacing device to enable the oil uniform saturability to be better, wherein six pre-interlaced nozzles are arranged, and the pre-interlaced pressure is 0.8-2 kg; 6, the tows are stretched through a godet at a high speed, nodes are made through a main interlacing device, and then winding formation is achieved through a high-speed winder, wherein the W / D speed is 5,900-7,900 m / min. According to the preparation method of the HOY spring wire, the number of traditional pre-interlaced nozzles is decreased to six, the pre-interlaced pressure is decrased to 1.0 kg, the cross air blasting speed is decreased to 0.7 m / s, and the spinning wheel speed is decreased to 5,900-7,900 m / min; under the technological conditions, the obtained HOY spring wire is good in winding effect and excellent in performance.

Description

technical field [0001] The application belongs to the technical field of spinning, and in particular relates to a preparation method of HOY spring wire. Background technique [0002] The process conditions of traditional HOY spring wire usually meet: W / D: 7000 / 2400; GR1: 6790 / 2100; GR2: 7100 / 2300120°, 12 imported oil nozzles for oiling, and 12 pre-network nozzles. Side blowing: 0.85m / s, pre-net pressure: 2.0kg, net pressure: 3.0kg. [0003] The technical problem existing in this process condition is that there are many broken ends, 5-6 per shift. Contents of the invention [0004] The purpose of the present invention is to provide a kind of preparation method of HOY spring wire, to overcome the deficiencies in the prior art. [0005] To achieve the above object, the present invention provides the following technical solutions: [0006] The embodiment of the present application discloses a preparation method of HOY spring wire, comprising steps: [0007] (1), polyester ...
