Non-woven is widely used as auxiliary materials of automobile industry due to its excellent sound absorption capability and good thermal property. The paper concludes that its density greatly affects sound absorption and thermal resistance, and an aluminum evaporated film can enhance the thermal resistance.

Poly(glycolic acid) (PGA) fibers produced by melt-spinning technology with different parameters may possess different structures, which may lead to different degradation behavior. In this paper, PGA fibers produced by different technology parameters were placed in phosphate buffer solution (PBS) (pH=7.4) at 37°C up to 2 weeks to investigate the effect of melt-spinning technology on the degradation in vitro. Changes in weight loss and tensile strength of PGA fibers during degradation were investigated. The results showed that drawing multiple, drawing temperature and inherent viscosity of polymer had the influence on the performance of PGA fiber during degradation. The changes in weight loss and tensile strength during degradation in vitro indicated that the PGA fiber produced with higher drawing multiple degraded more slowly. The PGA fiber produced on higher drawing temperature degraded faster. The PGA fiber made from higher inherent viscosity polymer degraded more slowly. © (2011) Trans Tech Publications, Switzerland.

The tensile performance of the woven membrane materials shows three characters: nonlinear, anisotropic and non-elastic. Besides, when suffering from the bi-axial loads, the tensile property of the woven membrane material is more complicated. These features make the analysis of the tensile performance of woven membrane materials more difficult. The analysis methods including the elastic matrix method, the mathematical function method, and the mechanical model method have been discussed in details.

A new flexible multilayer thermal insulation material is presented for applications at harsh environment as high as 433 K or as low as 123 K. A heat transfer model is established and solved to study heat transfer through the material, including radiation, solid heat transfer and gas heat transfer. Comparison between the experimental results and the theoretical prediction shows that the model is feasible to be applied in engineering. The temperature distribution of samples with 10, 15, 20, 25, 30 layers, respectively, the radiation, solid and gas heat transfer of a sample with 10 layers are analyzed at harsh conditions (123 K and 433 K) and the normal condition as well. The theoretical thermal analysis provides an active instruction to an optimal design of such protective materials.

As a kind of flexible fabric reinforced composites, the woven membrane materials suffer from the bi-axial tensile loads in the application of the lightweight structures. Therefore, the experiments under bi-axial tensile loads are essential for the acquaintance of the mechanical characters of the membrane materials. This paper has summarized thoroughly the details of the bi-axial tensile tests, especially the in-plane cruciform tests. The aspects include the shape and configuration of the cruciform sample, the practice of the applied stresses and the testing of the strains in the two axial directions. It could be expected to be the reference for the establishment of the testing standard of the bi-axial tensile experiment for the membrane materials.

With the decline of the undergraduate education quality and the enormous employment pressure of undergraduates, the value of the undergraduate education has been questioned recently in China. One of the effective methods in a very short time to solve the problem is to strengthen the practice teaching. The earlier and the more of the practice teaching could benefit the teaching effect of theoretical knowledge, and at the same time, the employment pressure could be solved. Besides, the comprehensive quality of young teacher could be enhanced. Only the practice teaching has been highly emphasized by faculty members and administrators of the college and been initiatively required by the students, the value of the undergraduate education could be reflected. © 2011 Springer-Verlag Berlin Heidelberg.

The air drawing model of a polymer in a melt blowing process is established and solved by introducing the numerical computation results of the air jet flow field of the dual slot die. The influence of the melt blowing processing parameters on the fiber diameter is also discussed. A lower polymer throughput rate, higher polymer melt temperature, higher air temperature, and higher air velocity can yield finer fibers. The results show great potential of this research for the computer assisted design of melt blowing technology.

Tussah silk fibroin is a promising material for drug release because of protein component, biocompatibility, aqueous processability, and biodegradability. Tussah silk fibroin nanoparticles were self-assembled and prepared in this paper. Their appearances and sizes were modified by altering the volume ratios between tussah silk fibroin and ethanol. When 9 mL of ethanol was added, the average microsphere size was 184.52 nm and the scattered index was 0.2903. The tussah silk fibroin nanoparticles for controlled drug release was studied and the result showed that the time of drug release was significantly longer. The process of drug release was divided into rapid release in early stage and slow release in late stage. The target drug delivery can reduce the negative effects and improve the effciency of the drug. As a result, it favors deeper investigation of tussah silk fibroin nanoparticles as drug carriers for controlled release of sensitive biologicals. © 2014 Binary Information Press & Textile Bioengineering and Informatics Society June 2014.
