Abstract
In order to clarify the mechanism of the contact behavior of integrated filament or staple such as knitted fabric and woven fabric, we have developed a system to measure the condition of the contact caused by pressure between fabric and solid hard flat surface. This system is composed of three parts: (1) to apply pressure to a sample, (2) to detect the contact spots and (3) to analyze the detected data.
By using this system we clarified the contact behavior of a polyester taffeta which consists of very crimped warp and of relatively straight weft. As a result we discovered that the mechanism of the contact behavior can be divided into following four regions: (1) the contact region in which the contact behavior is elastic, (2) the region in which the contact spot is deformed into slenderness within the warp filament, (3) the region in which the weft filament comes to contact and (4) the region in which the contact spots begin to harden by mutual interaction.
As mentioned above, we discovered that this system is of great use in order to analyze the contact behavior of the material with the complicatedly structured surface.
