Problems solved by technology

[0002] High-denier laminated fabrics have been unable to achieve good lamination fastness in transfer lamination. Because the fibers of the fabric are relatively thick and the surface of the fabric is not flat enough, if glue is applied directly, the fastness after lamination will not be good. , so it is generally necessary to carry out calendering treatment before this, so that the fabric can be flattened before continuing to fit. After calendering treatment, the style and appearance of the fabric may be changed
In addition, in order to improve the fastness of high-denier laminated fabrics, it is necessary to increase the amount of glue applied, which improves the fastness of laminated fabrics, but reduces the hand feeling and waterproof and moisture-permeable effects

Abstract

The invention discloses a shell fabric manufacturing technology for improving stripping strength of a high-denier gluing shell fabric. The manufacturing technology comprises the following steps of: A, preparing glue, wherein a mono-component moist reaction type adhesion agent is added to a primer; B, coating surface glue on release paper and drying in a step baking oven at 90 / 100 / 110 / 120 DEG C to form a surface glue layer, wherein the total thickness of the surface glue layer together with the release paper is 0.25mm-0.3 mm after drying; C, coating the primer on the surface of the surface glue layer and semi-drying, wherein the total thickness of the primer, the surface glue layer and the release paper is 0.3mm-0.35 mm after semi-drying; D, unreeling a shell fabric layer and the release paper at the same speed, and gluing the shell fabric layer and the primer at the pressure of 4-6 kg / cm<2> to form a semi-finished product which is then reeled; and E, stripping the release paper after the semi-finished product is mature. According to the manufacturing technology, the stripping strength of the high-denier gluing shell fabric can be improved, good handfeel and good waterproof and moisture permeable effects can be ensured, a calendering process is omitted, and the style and appearance of the shell fabric are ensured.
