The progress of process technology has brought about the upgrading of edging webbing products. In 1979, the trial production of the domestic generation SD9-9 rubber ingot belt was successful, which ended the history of rubber ingot belt products relying on imports.

Usually, the number of spindles is even, the woven tape is tubular, the number of spindles is odd, and the woven tape is flat. Spindle weaving technology has been applied since old China. The number of spindles varies from 9 to 100 due to different equipment.

The moisture in the air may cause spots in the car. When this kind of webbing contacts the clothes of passengers, the spots and colors on the luggage webbing will also be transferred to the clothes. Therefore, it should have anti spot fading characteristics, which is also called spot color fastness. The spot color fastness test includes multi fiber test and filter paper test. The multi fiber test is to clamp a sample of tissue belt between two layers of colored cloth. Immerse the mixed colored cloth into the vessel with distilled water and completely wet it. Then squeeze the water out of the extruder, and then clamp these colored cloth wrapped with selvedge webbing into the plexiglass sheet, put it into the sample holder, and lock the sample holder.
