New method for the objective evaluation of textile hand

The investigations presented show that pulling a disc-shaped specimen through the rounded hole can be considered as a perspective test method for textile hand evaluation. It was determined that the process of pulling a comparatively big specimen (circle divide 113 mm) through a relatively small hole (circle divide 20-40 mm) ends in the formation of a shell which has a complicated time-dependant shape. Under the stand of the test unit, the shell becomes cone-shaped, but above the stand it obtains the shape of a waved disc, the roughness of which increases with the decrease in its diameter. The aim of this research was therefore to reveal the application possibilities of pulling the material disc through the round hole for the objective evaluation of textiles hand, and to investigate the effect of fabric type, its anisotropy level, and the proper selection of testing regimes upon the character of the pulling process.
