Elliptic Fourier Analysis(EFA) is an important tool in shape reconstruction. To get the best female subject fitting result, we took the following processes. Firstly, three kinds of sampling methods were taken, including curvature sampling, random sampling and equally spaced sampling. According to our experiment result, equally spaced had the best performance. Secondly, eclectic sampling density was decided by the mean distance and conference. Finally, the number of harmonics used by EFA was decided by the experimental error requirement. The experimental results indicate that the EFA was an powerful and efficient approach in chest shape fitting.

Revealing the interaction mechanism of cellulose Iβ can help us to understand dissolution and modification mechanisms of cellulose fiber. In this paper, molecular dynamics simulation was used to analyze different interaction of cellulose Iβ. We found that the total interaction of Van der Waals, electrostatic and solvation energy per chain are -90.93 kcal/mol at 298 K. In order to get insight into the interaction mechanism, the energy distribution of each residue and mean interaction were analyzed. The interaction were divided into the intrachain, interchain and intersheet. The results show that Van der Waals interaction is important to stacking cellulose sheets, while the sum of electrostatic and solvation energy is also play a major role in intersheet interaction. Electrostatic energy plays a role certainly in the intrasheet interaction, and the thermal stability mechanism of intrachain is different to interchain.

Geomeshes can be employed to control erosion in conjunction with revegetation efforts, supplying seedbed protection from rainsplash erosion. In this study, jute and coir geomesheswere tested for erosion control performance under simulated rainfall conditions and germination using Shiwalik region soil. The performance of coir and jute geomeshes for rain splash erosion control were tested based on ASTM-D-7101 using a bench-sale setup with some modifications. Germination tests were performed according to ASTM-D-7322. Rain splash erosion control tests were carried out on three different slope angles of 15°, 30° and 45°. Jute geomeshes resulted in the improvement of erosion control and soil stability than that of coiralso the erosion control performance of geomeshes was observed to be influenced by the angle of soil slope. The objective of this study is to assess the performance capacities of biodegradable geomeshes that are commonly used for slope erosion control and vegetation establishment.

The production of the silk textile products with super softness and high suspension has become one of the hot and difficult topics in textile researches. To endow the silk fiber with improved softness, tensional drawing under different conditions was used to regulate the fiber structure and reduce the fiber initial modulus. The silk fiber structural and mechanical properties were tested before and after the tensional twisting treatments under wet and dry conditions respectively. The results showed that unlike the dry drafted twisting treatment, the pre-wet tensional twisting treatment induced more uniform helical structural formation with lower crystal destruction and molecule rupture than the dry one; though the breaking force decreased, the silk softness and breaking elongation were both improved after the pre-wet twisting treatment.

This work deals with the study of acoustic performance of perpendicular-laid nonwovens and their relation to fabric air permeability and thermal properties. Seven perpendicular-laid nonwoven fabrics were selected to examine sound absorption like average values of sound absorption coefficients () and noise reduction coefficient (NRC) as well as air permeability and thermal insulation properties. The Brüel and Kjær impedance tube instrument, Alambeta and FX3300 Air Permeability Tester were used for evaluation of acoustic, thermal and air permeability properties, respectively. It was observed that sound absorption had insignificant correlation with thermal conductivity while it was strongly correlated with thermal resistance. And the correlation coefficient of NRC and thermal resistance was 0.9835, indicating that NRC was directly proportional to thermal resistance of perpendicular-laid nonwovens. It also was observed that   was inversely proportional to air permeability, with correlation coefficient 0.95. It was concluded that a higher thermal resistance and lower air permeability suggested a better sound absorption performance for a perpendicular-laid nonwoven fabric.
