The physical properties of the surface quality requirements contained in the content, both the requirements of view, but also the inherent requirements, such as color requirements, friction resistance, resistance to soap color fastness to washing, length contraction rate, environmental protection and safety requirements. After washing, the zipper is used in place of people directly, therefore, the zipper appearance, style and sensory quality requirements to evaluate the quality of the whole zipper and influence.
