For clothing products, there is usually a collinearity relationship between different sensory properties evaluation. In order to obtain the relationship, 17 wool sweaters were used as the experimental objects, by using on-the-spot questionnaire survey, 9 specific sensory evaluations from 30 women assessors were obtained, which were then analyzed using the ridge regression method, so as to achieve the quantitative relationships among the overall impression and different sensory property evaluations of clothing. The weights of different sensory properties on the overall impression are sorted as flatness, elasticity, bulkiness, size proportion effect, neckline shape, hem shape, fuzz and pilling, damage, armhole joint shape. In addition, the accuracy of regression fitting between the predicted value from ridge regression equation and the actual surveyed value reaches 0.977. It does not only predict the consumers' sensory evaluation of product, but also help the enterprises to accurately focus on the consumers about products. In conclusion, ridge regression is proved to be a good method to study the quantitative relationship of sensory property evaluation with collinear relationship, and it can be widely used in kansei engineering of a variety of garments.
