Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present invention.

According to the embodiment of the invention, a processing technology of an anti-flooding upper surface is provided.

As shown in fig. 1, the processing technology of the color-overflow-preventing upper according to the embodiment of the invention comprises the following steps:

step S1, as shown in figure 2, pre-cutting the lower opening of the upper surface and splicing the color-impermeable cloth strips;

in the technical scheme, as shown in fig. 3, when the test piece color bleeding test method is applied, the obtained raw material cloth strip is subjected to a test piece color bleeding test in advance.
