Research For Quantification Of Cloth Hand And Sewability On Vehicle Interior Cover Materials 885042

The vehicle interior cover material requires good cloth hand and sewability with no wrinkle-and-slack to produce a superior quality.Usually, the evaluation for the cloth hand of cover materials depended on subjective judgement, and for the sewability has been relying on the experience of an expert. Therefore, an objective evaluation has not been performed. As the result, there were some cases where this matter has become a subject of discussion at planning and producing.In this research, the correlation to the usual measuring method, evaluation, and sewability was performed by measuring the very subtle values of cloth mechanical and surface properties.The results in outline are as follows;The test precision has been improved by applying the new evaluation method.The cloth hand for each kind of cover materials has been quantified by applying the mechanical properties.The outline of objective evaluation has been clarified by the relationship between the quality of sewability and mechanical properties.
