Problems solved by technology

[0008] In order to solve the problem that the polyester film for healds in the prior art is used in a humid water environment, there will be a certain amount of water between the two polyester healds, which will cause the two healds to stick together tightly, so that the two The smoothness between the heddles is poor, resulting in a decrease in the flatness of the cloth surface, which affects the production quality of the cloth. The invention provides a polyester film for heddles. The polyester film for healds is resistant to stamping and has a Good smoothness, which is beneficial to use in wet environment, and the production quality of cloth is improved

Abstract

The invention relates to a polyester film for heddles and a preparation method thereof, in particular to the polyester film with stamping resistance and smooth surface for the heddles and the preparation method thereof. The invention provides the polyester film for the heddles and the preparation method thereof for solving the defect of poorer smoothness of the conventional heddles. The surface of the polyester film for the heddles is of the matte surface, and the raw materials of the polyester film comprise semi-dull polyester chips, an anti-adhesion masterbatch, an antistatic agent and a color concentrate. The preparation method comprises the following steps of: preparing the raw materials of the polyester film to a polyester film base material through a biaxial stretching process, wherein the thickness of the base material is 300 mu m-350 mu m; and preparing the base material to the polyester film for the heddles through a matte surface treatment process. The polyester film for theheddles, provided by the invention is better in smoothness. The preparation method provided by the invention is simple and easy to operate.

Description

technical field [0001] The invention relates to a polyester film and a preparation method thereof, in particular to a punching-resistant polyester film for heddles on a matte surface and a smooth surface and a preparation method thereof. Background technique [0002] The water jet loom is a loom equipment commonly used in the textile field. The heald is one of the accessories of the loom. It is thin-walled and long. There are heddle ears for fixing at both ends, and a heald eye in the middle for the warp yarn to pass through. Each heddle controls a warp yarn, and when weaving, it drives the warp yarn to move up and down to form a shed, which is convenient for weft yarn introduction. Wherein the heald bar of the polyester chip heddle and the heald eye have an included angle of 20-30 degrees. Polyester chip healds are currently mainly used on water jet looms. [0003] There are two types of basic materials currently used to make heddles: [0004] 1. Stainless steel materia...
