Embodiment 1

[0023] A kind of production technology of polyester fiber, comprises the following steps:

[0024] a. Select PET cloth foam and PET bottle flakes as raw materials, according to the mass ratio, wherein the PET cloth foam is 50%, and the PET bottle flakes are 50%, cleaning, mixing, shredding and drying;

[0025] b. Put the dried raw materials into the screw extruder to melt to form a melt and extrude with the screw. The temperatures in the first zone to the sixth zone of the screw extruder are: 298 °C for the first area, 294 °C for the second area, and 294 °C for the second area. The third zone is 290°C, the fourth zone is 286°C, the fifth zone is 284°C, and the sixth zone is 282°C. The prepared melt passes through the flange area, and the temperature of the flange area is controlled at 270°C, and then filtered through a filter. During the filtration process The temperature is controlled at 276°C. The filter is filtered with two layers of filter screens. The meshes of the two la...

Embodiment 2

[0032] a. Select PET cloth foam and PET bottle flakes as raw materials, according to the mass ratio, wherein the PET cloth foam is 40%, and the PET bottle flakes is 60%, cleaning, mixing, shredding and drying;

[0033] b. Put the dried raw materials into the screw extruder to melt to form a melt and extrude with the screw. The temperatures in the first zone to the sixth zone of the screw extruder are: 298 °C for the first area, 294 °C for the second area, and 294 °C for the second area. The third zone is 290°C, the fourth zone is 286°C, the fifth zone is 284°C, and the sixth zone is 282°C. The prepared melt passes through the flange area, and the temperature of the flange area is controlled at 270°C, and then filtered through a filter. During the filtration process The temperature is controlled at 276°C. The filter is filtered with two layers of filter screens. The meshes of the two layers of filter screens are 80 mesh and 50 mesh respectively. The filtered melt enters the insu...

Embodiment 3

[0040] a. Select PET cloth foam and PET bottle flakes as raw materials, according to the mass ratio, wherein the PET cloth foam is 80%, and the PET bottle flakes is 20%, cleaning, mixing, shredding and drying;

Abstract

The invention provides a production technology of a polyester fiber. The production technology comprises the steps of selecting PET (Polyethylene Terephthalate) fabric foams and PET bottle chips, cleaning, mixing, shearing, drying, fusing, extruding, filtering, spinning, doffing, bundling, drafting, curling, cutting off, heat setting and drying, thereby forming products, wherein plate changing period of components can be improved effectively by adjusting the settings of processing temperature and changing the filtering accuracy of a filter net of components, addition of the fabric foams is more than 50%, and production cost is reduced greatly, which facilitates mass production.

Description

technical field [0001] The invention relates to a technology for recycling waste materials, more specifically a production process for polyester fibers. Background technique [0002] PET plastic is a polyterephthalic acid plastic with a highly symmetrical molecular structure and a certain crystal orientation ability, so it has high film-forming properties and synthetic properties. Bottles made of PET plastic have the advantages of high strength, good transparency, non-toxicity, impermeability, and light weight, so they are widely used. Since PET plastic can be melted, drawn, and then formed into fibers, more and more PET plastics are used in production to produce polyester fibers. [0003] At present, in order to reduce the production cost of hollow fibers, most of them use recycled PET plastic bottle flakes to produce polyester fibers. However, polyester rags are difficult to remove impurities such as oil, slurry and various finishing agents contained in them, resulting i...
