Production method for stationery clamp screen cloth

Abstract

The invention relates to a production method for stationery clamp screen cloth. The production method for the stationery clamp screen cloth sequentially comprises the following steps of (1) a step of producing polyester slices, namely, enabling terephthalic acid and ethylene glycol with the mass ratio of 1 to 2.5 to be formed into raw materials, polymerizing the terephthalic acid and the ethylene glycol into polyester materials under the temperature of 285 DEG C, enabling the intrinsic viscosity of the polyester materials to be 1.1 and processing the polyester materials into polyester slices; (2) a step of producing yarns, namely, performing pre-crystallization on the polyester slices through a pre-crystallizer, pre-heating the polyester slices through a preheater, performing solid-phase polymerization on the polyester slices through a solid-phase polymerization reaction device, melting the polyester slices through a screw extruder and a heating device and drafting and forming silk strips through a drafting winding machine; (3) a step of forming the screen cloth, namely, producing into the screen cloth through warp yarns, weft yarns and binding yarns. The production method for the stationery clamp screen cloth has the advantages of being simple in technology, enabling operation to be easy and enabling produced screen cloth to be high in intensity and good in toughness.

Description

technical field [0001] The invention relates to a method for manufacturing mesh cloth, in particular to a method for manufacturing mesh cloth used in stationery holders. The mesh cloth produced by the manufacturing method is specially used in stationery holders. Background technique [0002] Mesh cloth, also known as base cloth and mesh cloth, has a wide range of uses, and some manufacturing methods of mesh cloth have been disclosed, such as in the Chinese patent whose publication date is December 07, 2011, and whose publication number is CN102268817A, Disclosed is a PVC mesh cloth and a manufacturing method thereof. The parts by weight of the various components of the PVC mesh cloth are: 70-100 parts of dioctyl phthalate, 100 parts of PVC paste resin, 3 parts of stabilizer, CaCO 3 40-100 parts, 0-5 parts of viscosity reducing agent; in this manufacturing method, the scraper used is a circular scraper, when the cloth base passes over it, it can scrape off the excess slurry o...

Problems solved by technology

[0003] However, due to the different uses of the mesh, the performance requirements of the mesh are quite different. For example, the mesh used in the stationery folder requires high strength and good toughness. At present, there is no such thing as a mesh used in the stationery folder. method
