Seamless adhesion preparation method of double-layer cloth

Abstract

The invention relates to a preparation method for seamless bonding of double-layer cloth, which comprises the following steps: preparing roll-shaped fabric A, fabric B, single-sided adhesive and hot-melt adhesive film, and the hot-melt adhesive film includes mucous membrane and release film. Pattern paper; import the hot melt adhesive film into the die-cutting machine, and punch out the hollow inner hole and the first positioning hole of the hot melt adhesive frame according to the shape of the hot melt adhesive frame; import the hot melt adhesive film and fabric A into hot-press lamination Fitting in the equipment; paste the single-sided adhesive on the fabric A to form a temporary positioning complex; import the temporary positioning complex into the die-cutting machine, and punch out the second positioning holes on both sides of the single-sided adhesive; Tear off the release paper on the hot-melt adhesive film processed in step (6), then compound the fabric B with the adhesive film on the side of the torn-off release paper, and then heat-press and bond the outer frame as a whole Die-cutting; the accuracy of the size after the double-layer cloth is bonded, the appearance is very flat, and it can greatly reduce the input of manpower and equipment.

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...
