Scheme 1: the water ripple on the coating surface of the finished product causes the whole product to be out of standard.
Scheme 2: the fabric surface of the finished product has a dot-shaped black pockmark state before finishing, and the finished product does not meet the standard.
scheme 3: the finished product number coating has water ripple problem, which causes the whole product to be out of standard.
Scheme 4: the finished product has poor coating fastness, and the adhesive tape can fall off and can not meet the standard.
scheme 5: the flatness of the pit edge is 2-3cm after the finished product is finished, so that the finished product cannot meet the standard.
Taken together, all the examples show that in the embodiment of the invention, the polyurethane TPU black film and the water-based foaming coating have good combination, so that not only is the water ripple of the cloth surface eliminated, but also the light shading property, the fastness and the flatness of the composite type roller shutter fabric are improved. In addition, the foaming coating contains the color adhesive, so that richer and fuller colors can be blended, and the defects of monotonous color and the like of the traditional composite fabric are overcome.
