Thermalperformance Of Automotive Seatingfabrics And Integration Finishing Of Flame-Retardant And Light Fastness

In21st century, the world of science and technology is undergoing profound changes. More and more people pay attention to the high-tech industry that the automotive industry stands for. The development and application of automotive textiles have become essential, in particular the automotive seating fabric which accounted for the larger proportion in the automotive textiles. Although there have been dozens of professional manufactures at present in China, compared with developed countries there is still a considerable gap. The high-performance chemical fibers required for automotive seating fabrics, high-performance sponge, knitted lining materials, as well as high-end automotive seating fabrics mostly depend on imports. And the sealing fabrics produced independently by domestic enterprises still have many problems in functionality, such as flame resistance, light fastness and other factors, because of the technology and cost of production. Therefore, studying the performance and the functional finish of automotive seating fabrics has positive significance to the development of innovative seating fabrics.In addition to the basic study of the topic mechanical properties and thermal properties of composite car seat fabric*we studyed the flame-resistant fabric finishing and the sun-resistant finishing of the car seat surface in this thesis. The basic physical and mechanical propertiesincluded tensile, breaking, tearing, breathable, crease recovery, etc.,and thermal properties, included combustion performance of car seat fabric, decomposition when temperature increase, hot melting. The results indicated that air permeability of the surface fabrics was decreased after composited with the polyurethane sponge, but increased after composited with the base fabric; the tearing strength was increased after composited.The elongation at break of the composite materials along the warp and weft are similar witiht monolayer fabric.The flame retardant performance of fabric wereimproved after composited.The thermal stability of the two kinds of fabrics reducedafter fabric with sponge compound,The flame retardant and light resistant of the car seat fabric has become more and more important indicators in a real world application. Therefore the two functions were researched in this paper. After the single factor experiment was carried out for the flame retardant finishing, this paper selected four factors:of flame retardant agent, dosage of sodium carbonate, roller pressure, baking temperature, and then set three levels for each of the four factors, which formed the four factors three levels orthogonal experiment. Then the impact of each factors and the optimum parameters were obtained by range analysis.After analyzing the results of orthogonal test and verification, this article selected the optimum technology of flame retardant finishing.when consumption of flame retardant agent was12g, sodium carbonate dosage was0.075g, rolling time of was60s, stick pressure was0.5MPa, the curing temperature was170℃, pressure leaching time was15min+15min, pre-drying time was3min, JFC was two drops, the damage length was the shortest.Light-resistant finishing was also consists of single factor experiment and orthogonal test, The results of the tests indicated that optimal technological parameter of sun-resistant agent HTUV100was when the light fastness dosage was4g, dipping time was30min, rolling stick pressure was0.5MPa, pre-baking temperature was90℃, pre-drying time was5minutes, baking temperature was160℃, curing time was60s.After the optimal technological parameter of the two function finishes, this paper integrated the two function finishes. Comparing the results of the flame-resistant finishing firstly and then sun-resistant finish with the results of the opposite order, this paper concluded:flame-retardant finish firstly, and then light-resistant finishing during integration testing was better. And the specific process parameters of the integration testing, firstly flame retardant finish:consumption of flame retardant agent was12g, sodium carbonate dosage was0.075g, rolling time of was60s, stick pressure was0.5MPa, the curing temperature was170℃, pressure leaching time was15min+15min, pre-drying time was3min, JFC was two drops; then light-resistant finishing:the light fastness dosage was4g, dipping time was30min, rolling stick pressure was0.5MPa, pre-baking temperature was90℃, pre-drying time was5minutes, baking temperature was160℃, curing time was60s.
