Objective evaluation model of visual elegance of swirl skirts - Part (I): regression method

摘要

The elegant impression of swirl skirts has been well received by most ladies, yet the textile industry does not have an objective method of evaluating the visual elegance of swirl skirt by grades. In the present study we there for use fabric mechanical properties through the KES-FB system to predict the elegance of swirl skirt manufactured that is to create a method for objectively evaluating visual elegance of swirl skirt by grades. From the study it is found there is a notable correlation between fabric mechanical properties and the visual elegance of swirl skirt by grades. It can also establish a objective evaluation model of visual elegance of swirl skirt by grades basing on the regression method using several key fabric mechanical properties, in which the said models pass the fitting test with results exceeding 0.80. In addition, in the present study we use stepwise regression selection method to pick out the most significant key factors (bending rigidity and shear hysteresis at 0.50) affecting the visual elegance of swirl skirt by grades and then reapplies the regression method successfully thus establishing a method only using two fabric mechanical properties for objective evaluation of the visual elegance of swirl skirt by grades, in a more simple and objective manner.
