Seamless adhesion preparation method of double-layer cloth

Abstract

The invention relates to a seamless adhesion preparation method of double-layer cloth. The seamless adhesion preparation method of the double-layer cloth comprises the following steps: preparing coiled fabric A, fabric B, single-sided adhesive and a hot-melt adhesive film, wherein the hot-melt adhesive film comprises an adhesive film and release paper; guiding the hot-melt adhesive film into a die-cutting machine, and die-cutting a hollow inner hole and a first positioning hole of a hot-melt adhesive frame according to the shape of the hot-melt adhesive frame; guiding the hot-melt adhesive film and the fabric A into a hot-press adhesion equipment and performing adhesion; adhering the single-sided adhesive to the fabric A to form a temporary positioning composite body; guiding the temporary positioning composite body into the die-cutting machine, and die-cutting the two sides of the single-sided adhesive to form a second positioning hole; tearing off the release paper on the hot-melt adhesive film processed by the last step, compositing the fabric B and one side, on which the release paper is torn off, of the adhesive film, performing hot-press adhesion and finally performing whole die-cutting on the outer frame. The size accuracy is improved after adhesion of the double-layer cloth and the appearance is very flat; in addition, human input and equipment input can be greatly reduced.

Description

technical field [0001] The invention relates to a process for seamless bonding of double-layer cloth, in particular to a preparation method for seamless bonding of double-layer cloth. Background technique [0002] At present, it is necessary to solve two pieces of fabric A and fabric B with the same shape, which are partially bonded by hot-melt adhesive film, and the hot-melt adhesive film has requirements for shape and position relative to the fabric. The traditional process is as follows: [0003] 1. Cut fabric A and fabric B through the cutting bed; [0004] 2. Cut the hot melt adhesive film C of a specific shape by punching machine or laser; [0005] 3. Relying on personal operation, attach the hot-melt adhesive film C to the fabric A with the help of heating equipment to form the primary complex D; [0006] 4. Tear off the release paper of the hot melt adhesive film on D to form a secondary complex E; [0007] 5. Relying on personal operation and manual alignment, p...
