| As a project cooperated with Peugeot Citroen Automobile Group, the author together with Xavier FLAMENT, senior engineer of Intissel, a famous non-woven manufacturer in France, worked in his textile research center, on the flame retardant of the vehicle-use spunbonded polyester non-woven and its optimization analysis.Spunbonded polyester non-woven, as a new material, is being widely used for heat insulation in the engine hood, and it causes a universal concern in the industrial textile world. The author analyzed the flame-retardant effect, its process design, costing, environment and other factors, summarized the problems during the testing process, and gave us a conclusion under the framework of European textile materials standard for vehicle use by using chemical test, coupled with the physical properties and mathematical optimization method.In this paper, the author studied the retrospective analysis of a non-woven flame retardant technology and automotive demand, proposed the initial pilot testing program, and found out a most suitable method for the second part of the trial. Then he designed parameters by using Matlab to optimize their portfolio, for the purpose: Reduce the combustion time; reduce the burning length and the control pyrocondensation rate. The detail as follows:1. Nitrogen-phosphorus flame retardant showed a good performance-cost ratio.2. Through the study, in process design, the author proposed a combination of padding machine and dryer.3. In many adjustable parameters, the oven temperature, the time caused a huge influence to the fire retardant effect, after generalized all the analysis results by using Mathematics modeling, the author found that the increase of the concentrations and lower oven temperature and curing time could give us a most visible effect of fire retardant.4. This paper used the regression equation, and objects programming method to build an optimized mathematical model, and finally got the optimal solution. |
