Physical properties of automotive textiles and design for child seat in modified pick-up vehicle

Abstract

The objective of this research is to design the layout and identify the suitable fabric for child seat on the modified pickup vehicle using low manufacturing process. The 1800D polyester covered by PVC (polyvinylchloride) and 420D nylon are selected to be candidate specimens because of affordable and abrasive conditions. To identify the strength and elongation, fabric specimens were tested with a tensile testing machine based on ASTM D5035-11 standard with strip method. As a result, the force responses of both fabrics can support Thai students from age of 6 to 14 years old with average of 33.7 kg weight. The specimens from polyester and nylon fabrics had different force responses in principal directions from standard fabric roll. But the specimens from polyester fabric were approximately the same in such directions. However, the experimental results can predict methods of textile production in knitting and woven techniques. Furthermore, the waft and warp densities with such techniques have influences on the force responses and elongation of fabrics. Therefore, the 1800D polyester covered by PVC is suitable candidate because of the knitting technique that can provide thicker and stronger fabrics in both principal and bias directions.
