Abrasion is a common issue in zipper use. By optimizing the sewing lines and structure, SBS has launched AR (abrasion resistance) zipper.
Optimizing 1：high-strength sewing lines
SBS utilizes high-strength sewing lines to prevent the teeth from falling out, reducing wear and aging during long-term use.
Optimization 2: the structure of teeth and slider
The surface of the AR zipper teeth adopts a notchy design, locking the sewing line inside the notch. Besides, the inner cavity of the slider has been changed. Pulling and closing the board does not directly cause friction to the sewing lines, which helps reduce wear and tear.
This zipper offers abrasion resistance and smooth operation, and SBS recommends it for use in cases and bags.
