Sliding Characteristics of Slide Fastener on Tactile Perception

Abstract

Slide fasteners are one of the textile end-uses that have permeated daily life. The objective is to elucidate ways to improve the quality and value of slide fasteners. In this report, from the viewpoint of tactile perception on the tensile load transmitted to user’s fingers through a slider in sliding a fastener, the sensory and affective impressions (hereinafter referred to as the slide-feeling) and the quantitative evaluation indexes on the slide-feeling were investigated. In the evaluation of the slide-feeling on the tactile perception of the slide fastener, the term related to Light/Smooth, i.e., one of “Smooth,” “Not stiff,” “Light,” “Flat,” “Loose,” “Readily,” and “Supple,” and the term of “Luxurious” are main evaluation terms. For the term related to Light/Smooth, the energy of tensile load from the stationary state to the moving start of the slider and the average value of tensile load from the begin to the end of the slider move are effective evaluation indexes. The term of “Luxurious” requires evaluation indexes other than the followings; the energy of tensile load from the stationary state to the moving start of the slider and the average of tensile load from the moving start to the moving end of the slider.
