S6: and sewing the elastic composite surface layer 1 and the flexible base inner layer 4 together by using a stop stitch 2 to obtain the fabric.
Comparative example 1:
comparative example 1 is substantially the same as example 1 except that: in the manufacturing process, the flexible grey cloth is not treated by dipping a softening agent.
Test:
the elasticity was measured according to the standard FZ/T70006, and the results are shown in Table 1.
Figure DEST_PATH_IMAGE001
As can be seen from the above table, the invention has low deformation, high elongation, high recovery, and better elasticity, while the comparative example has high deformation, low elongation, low recovery, and poor elasticity. In addition, for the ultraviolet resistance, the ultraviolet resistance is not described in detail because the invention is mainly realized by relying on the existing ultraviolet resistance auxiliary agent.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
