Preparation procedure of high-strength environment-friendly polyester abrasive belt base cloth

Abstract

The invention discloses a preparation procedure of high-strength environment-friendly polyester abrasive belt base cloth and relates to the technical field of textiles. A preparation method comprises the steps of classifying, cleaning and pulverizing waste drink bottles through a crusher, heating the waste drink bottles to the melting point for preparing melt, extruding the melt out of spinneret orifices with a metering pump through a screw extrusion machine, condensing the melt in air for forming fine strips, processing polyester staple fibers through a spinning procedure, obtaining polyester yarn, adopting a blowing carding machine for conducting blowing carding treatment on warp yarn and weft yarn mixed fabrics, adopting a drawing frame for conducting drawing on polyester fibers, the warp yarn and weft yarn mixed fabrics and double-strand cotton fibers, then using a roving frame for conducting spinning, then making the fabrics and the fibers enter a spinning frame for being spun into spun yarn, conducting spooling, after spooling is ended, conducting beaming, after beaming is ended, conducting slashing, subsequently, making the spun yarn enter an air-jet loom, obtaining the base cloth, conducting finishing and packing, and then warehousing the base cloth. Advanced spinning equipment such as the roving frame is under automatic control of a computer in the preparation process, light-ration and smooth-drafting processes are adopted, resultant yarn quality is improved, a pure starch sizing agent containing no PVA is adopted in the formula, and environmental pollution caused by desizing is reduced.

Description

Technical field: [0001] The invention relates to a preparation process of a high-strength environment-friendly polyester abrasive belt base cloth, belonging to the technical field of textiles. Background technique: [0002] Since my country's reform and opening up, the national economy has grown rapidly, "scientific and technological innovation, independent innovation" has become the mainstream of my country's current industrial development, and my country's industry is gradually developing in the direction of intensive, energy-saving, emission-reducing, and low-carbon. [0003] Abrasive belts are coated abrasives in machine tools and are called flexible abrasives. They are more flexible, safer, and more precise than solid abrasive wheels during polishing. At the same time, the grinding cost is low. Abrasive belts are generally composed of four major elements. , that is, matrix, binder, abrasive and structural composition. In the production process of the abrasive belt, the...

Problems solved by technology

At present, the main raw material of the high-grade abrasive belt base cloth produced in the domestic coated abrasive industry is cotton cloth, but the cotton base cloth has the disadvantages of many impurities, low strength, poor wear resistance, light weight, short life, and high cost.
