Abstract

The invention discloses a measuring method and a measuring device of dynamic friction characteristics on the textile surface. The measuring device comprises a measuring assembly, a reciprocated motion mechanism, a lifting mechanism and a machine frame, wherein the measuring assembly comprises a sliding block fixed sleeve and a sliding block, flanges arranged at two ends of the sliding block are installed in a groove of the sliding block fixed sleeve, the vertical direction of the sliding block is floating, and the measuring device can change the location of the machine frame through the lifting mechanism. According to the measuring method, the reciprocated uniform speed linear motion of the sliding block is achieved by means of the reciprocated mechanism, and therefore friction force born by the sliding block can be converted into side pressure of the sliding block on the sliding block fixed sleeve, and measurement of the dynamic friction coefficient and static friction coefficient on the textile surface can be achieved by means of measurement of dynamic change of the side pressure. Three friction characteristic indicators such as the dynamic friction coefficient, the static friction coefficient and the frictional work on the textile surface can be obtained by means of once measurement and calculation of the whole measuring device. The measuring method and the measuring device of the dynamic friction characteristics on the textile surface can be applied to textile detection industry and can achieve quick measurement of the friction characteristics on the textile surface.

Description

technical field [0001] The invention belongs to the field of testing the physical properties of textiles, in particular to the field of testing the surface friction properties of textiles. Background technique [0002] The coefficient of friction is one of the basic properties of various materials. When there is relative motion or relative motion tendency between two objects in contact with each other, the mechanical force that hinders the relative motion generated on the contact surface is friction force. The friction performance of a certain material can be characterized by the dynamic and static friction coefficient of the material. [0003] The surface friction characteristics of textiles are an important factor to measure the comfort of textiles, and also one of the decisive factors for consumers to evaluate the quality of textiles. Therefore, it is particularly important to study the friction characteristics of textiles in the research and development of textile prod...
