Using Rubber Nozzle for the Evaluation of Fabric's Bending Rigid

Using Rubber Nozzle for the Evaluation of Fabric's Bending Rigidity
Ali-Asghar Alamdar-yazdi, Seyed Mansour Bidoki

Abstract
A novel method of evaluating fabrics' bending rigidity is presented using rubber nozzles. Reversible expansion of the rubber nozzle can solve the hardship of choosing the optimal radius of the conventional solid nozzles for different fabrics Bending behaviour of the 19 woven fabrics of different varieties was evaluated by KES and the values were the base of
comparison. The samples were also extracted through a 25 mm diameter rubber ring (extendable to 35 mm) and the nominal slope angle of each curve, calculated from the starting point to the maximum extraction point (Fig. 2) was subsequently measured. Very high level of correlation (0.92) between the curves' nominal slopes and the bending rigidity
of the samples is observed using multiple regression analysis. High correlation of the data in this experiment recommends using rubber nozzles instead of normal solid openings for the evaluation of fabric properties.
