Method for manufacturing fabric interlayer in stationery folder

Abstract

The invention relates to a method for manufacturing a fabric interlayer in a stationery folder. The method includes the following steps in sequence: (1) a polyester chip manufacturing step that raw materials used are composed of terephthalic acid and ethylene glycol in a mass ratio of 1:2.5, the terephthalic acid and the ethylene glycol are polymerized into polyester at 285 DEG C, the intrinsic viscosity of the polyester is 1.1, and then the polyester is processed into a polyester chip; (2) a yarn manufacturing step that a pre-crystallizer is used for pre-crystallization of the polyester chip,a preheater is adopted to preheat the polyester chip, a solid phase polymerization reaction device is adopted to conduct solid phase polymerization on the polyester chip, a screw extruder and a heating device are adopted to melt the polyester chip, and a drafting winder is adopted to conduct stretching and shaping on threads; (3) a fabric forming step that warps, wefts and tying yarns are adoptedto make a fabric. The method is simple in process and easy to operate. The manufactured fabric has high strength and good toughness.

Description

technical field [0001] The invention relates to a method for manufacturing cloth, in particular to a method for manufacturing a cloth interlayer used in stationery folders. Background technique [0002] Cloth, also known as base cloth and grid cloth, has a wide range of uses, and some cloth manufacturing methods have been disclosed, such as the Chinese patent on December 07, 2011 with publication number CN102268817A, which discloses A PVC cloth and a manufacturing method thereof, the parts by weight of each component of the PVC cloth are: 70-100 parts of dioctyl phthalate, 100 parts of PVC paste resin, 3 parts of stabilizer, 40-100 parts of CaCO3, 0 to 5 parts of adhesive; 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 on the cloth base at one time, and make no residual slurry in the hole When the viscosity of the slurry is high and the cloth base becomes thicker, the excess slurr...

Problems solved by technology

[0003] However, due to the different uses of the cloth, the performance requirements of the cloth are quite different. For example, the cloth used in the stationery folder requires high strength and good toughness. At present, there is no manufacturing method for the cloth interlayer in the stationery folder.
