Embodiment 1

[0024] A double-sided coating process for cylindrical mesh cloth, comprising the following steps:

[0025] 1) Use a double-needle bed warp knitting machine to directly weave into an integrated cylindrical mesh;

[0026] 2a), send the cylindrical mesh into the heat setting machine for heating, the heating temperature is 190 degrees, and the heating time is 20 seconds;

[0027] 2b) Cool the cylindrical mesh cloth after the first heat treatment, and send it to the heat setting machine for heating again, the heating temperature is 100 degrees, and the heating time is 30 seconds;

[0028] 3a), the heat-set cylindrical mesh is completely cooled and flattened into a double-layer structure, and then immersed in a liquid coating additive under the action of a pulling roller, so that the mesh is completely immersed in the additive;

[0029] 3b) After dipping, the mesh cloth passes through the padding car in open width, and is extruded by the rolling car to squeeze out the excess additi...

Abstract

The invention discloses a double-surface coating process of cylindrical screen cloth. The double-surface coating process comprises the following steps of subjecting integrally molded cylindrical screen cloth to heat setting treatment for twice in sequence, then subjecting the cylindrical screen cloth to gum dipping and gum rolling treatment, and finally carrying out oven-drying treatment on the cylindrical screen cloth. By using the double-surface coating process, the convenience is provided for the subsequent production of a product using cylindrical coating screen cloth; the production efficiency is greatly improved; the cost of the product is decreased; the cylindrical screen cloth is subjected to heat setting at different temperatures for twice in sequence; internal stress generated by a textile fiber in a stretching process is eliminated by utilizing different heat power; the slackness of a macromolecule is enabled to basically reach the most balance; therefore, the cylindrical screen cloth is enabled to be more stable in structure and be good in toughness; the cylindrical coating screen cloth is integrally cylindrical, and compared with a cylindrical product which is sewed by common open-width screen cloth, as subsequent sewing processing does not exist, has no risk that a sewed position is easily cracked; the quality of the product is improved; meanwhile, the appearance is also more attractive.

Description

technical field [0001] The invention relates to the field of post-processing and finishing of fabrics, in particular to a double-sided coating process for cylindrical mesh cloth. Background technique [0002] A coated fabric is a textile in which a coating-bonding material has been applied in situ in a single or multiple layers on one or both sides of the fabric. Consisting of two or more layers of material, at least one of which is a textile and the other is a completely continuous polymer coating. [0003] Coating technology in a broad sense also includes lamination, that is, applying a layer of adhesive on the base cloth, covering it with a layer of film or other materials, heating and pressing to form a composite fabric; or the film itself is the adhesive material, Bond the base fabric with other materials. [0004] In a narrow sense, it is the process of scraping the coating material onto the surface of the fabric. The coating method of the fabric coating should be s...
