The paper selects 18 blended yarns with kapok fiber and other fibers, which were manufactured by different spinning technologies, to explore the most efficient spinning yarn technology of kapok fiber. Four properties of these blended yarns were tested including the fineness unevenness, breaking tenacity, yarn defects and hairiness. According to the standards USTER STATISTICS-2007, GB-T/398-2008 and FZ12001- 1992,the analytical results of four properties show that the quality of kapok blended yarn get a better level with the improvement of spinning technology. The compact and IV spinning technology is the optimal way to spin kapok blended yarn with high quality, which supplies a support of widening the application of kapok fibers in various products.

Green composite made from ramie fabric and polypropylene (PP) is a kind of recyclable and environmental friendly material. Ramie fiber tows have relatively good mechanical properties comparing with other bast fibers, and hence the fabric woven by ramie yarn shows excellent in-plane mechanical behaviors. PP can be fully recovered and recycling used for its thermoplastic character. Ramie fabrics reinforced by PP have better shape formability and maintenance. In this paper, we proposed a plain weave in sample dobby loom, and reinforced four laid-layers together by PP particle through hot pressing. The mechanical behaviors of the ramie-PP composite were tested by MTS-810 Material Testing System in weft and warp directions separately which were essential parameters to the following topology optimization in finite element analysis (FEA) software. A body of eco-power automobile consisting of shell and chassis was original designed in Pro/E® Wildfire 5.0. For the chassis is the main bearing structure, it is an important part in the eco-power automobile body and was chosen to be topology optimized. Fiber volume fraction and structure optimization of the chassis model are evaluated and simulated to guide the material formation of manufacture progress. © (2012) Trans Tech Publications, Switzerland.
