Embodiment 1

[0012] Preparation of high-strength composite fabrics:

[0013] Coat the first adhesive layer on one side of the base fabric, then apply the polyester filament fiber layer on the first adhesive layer by hot pressing, then coat the second adhesive layer, and finally heat the PE / PP composite layer Press and apply on the second adhesive layer. The thickness of the base cloth is 0.22mm, the thickness of the adhesive layer is 0.05mm, the thickness of the polyester filament fiber layer is 0.15mm, and the thickness of the PE / PP composite layer is 0.2mm.

[0014] The polyester filament fiber in the polyester filament fiber layer is prepared by the following method: after PET polyester is melted, a mixed solution of ethylene glycol and germanium dioxide catalyst is added to carry out alcoholysis and repolymerization reaction, and the viscosity of the reaction product is controlled to be 0.7dl / g, enter the spinning box for spinning, and the temperature of the spinning box is 300°C.

Abstract

The invention discloses a preparation method of a high-strength composite fabric, which comprises the following steps: a first bonding layer is coated on one side of base cloth, then a polyester filament fiber is stuck on the first bonding layer through hot-pressing, next a second bonding layer is coated, and finally a PE / PP composite layer is stuck on the second bonding layer through hot-pressing; a preparation method of polyester filament fibers in the polyester filament fiber layer comprises the following steps: after PET polymers are melted, a mixed liquor of glycol and a germanium dioxide catalyst is added so as to carry out the alcoholysis reunion reaction, wherein the viscosity of the reaction product is controlled to be 0.7-0.8 dl / g; the reaction product enters into a spinning manifold to be spun, wherein the temperature of the spinning manifold is 300-350 DEG C. The prepared high-strength composite fabric is formed by adopting a composite hot-pressing way, and has the advantages that the processing process is simple, the operation is easy, the cost is low, and the industrial production is easy.

Description

technical field [0001] The invention relates to a method for preparing composite fabrics with high strength. Background technique [0002] Teslin fabric is a special textile produced by shuttleless looms. The warp and weft are made of composite yarns with a special covering structure, that is, PVC / PET sheath-core yarns. This type of fabric has the advantages of smooth surface, waterproof and oil-proof, wear-resistant, and long service life. However, special equipment is required for manufacture, and the process is more complicated, and the mainly used PVC material contains vinyl chloride monomer, which is toxic to a certain extent. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for preparing a high-strength composite fabric to overcome the above-mentioned defects in the prior art. [0004] In order to solve the above-mentioned technical problems, the preparation method of the high-strength composite f...
