The Study of Stain Accumulation Mechanism in the Vehicle Seats

The various seat problems are happening in the field. Customers are getting more sensitive to the quality of a vehicle than ever these days. The long-term accumulated staining of iInterior trim contamination, as a result, is one of the most important factors in regarding that of the vehicle and newly reflected in IQS in 2007 and VDS in 2008 respectively. In particular, seat staining contamination has been mainly responsible for the decrease of vehicular marketability and used-car price. Therefore seat must be improved not to be stained contaminated easily. The stain accumulation contamination mechanism of both natural genuine and artificial leather seats is different from that of fabric cloth seat and we hereby verified them systematically. We developed the test method regarding the actual-conditioned wears (abrasions), soil contamination resources and environment circumstances and that it'll be of service to the vehicle development test. Moreover, 153 fabric samples genuine cloths, which are used for HKMC fabric cloth seat, are classified under six clusters, and 29 representative samples are chosen. With these results analyzed, design guide was finally completed and that it leads us to the conclusion that which fabric cloth is the strongest to the staining contamination from the design concept stage.
