Published: September 2011

It is necessary to analyze the structural strength of the moving arm and make some optimization designs to reduce its weight. According to the actual structural sizes of the moving arm of a loader, we build its 3D mathematical model by bottom-to-up modeling method in ANSYS. Having considered bearing actual loads and displacement constraint conditions of a moving arm in actual working situations, we got the stress distribution rules and the destructible locations of the moving arm in a working cycle after analyzing the strengths of the moving arm in six different typical kinds of working conditions. Based on this, we made the design module and the structural optimization designs of the moving arm by using first-order method based on the objective function's sensitive degree to design variables in ANSYS software. The results of the study suggest that the maximum equivalent effective stresses in six different typical kinds of working conditions are all less than the admissible stress of the material of the moving arm, and the maximum bearing stress exists in the working condition with bearing unbalance loadings in horizontal and vertical directions. The advantage of the optimization design is outstanding with the 67% less of the maximum equivalent stress of the moving arm and 15.4% less of the volume.

Study on the Origin of Textile Technology in Ancient China
Authors: Li Qiang , Li Bin
Published: September 2011

Some researchers use the drawing about primitive hunting with stone balls in order to explain the origin of textile technology in ancient China. However, the description in the drawing is inconsistent with the historical facts and lead to a wrong conclusion drawn by the researchers. We aimed to explain objectively the origin of the textile technology in ancient China. We have had some queries for the authenticity of the drawing after we made some archaeological and folk-custom investigations on the application of primitive stone balls. It is concluded that the origin of spinning in ancient China dated back to the upper Palaeolithic period and was an indispensable link of human evolution from ape man to human, but the origin of weaving in ancient China dated back to the Neolithic period. Only when the primitive farming became the main production department and the explosion of population required the substitute of clothes made of hide, did the spinning, weaving and textile design merged together and finally resulted in the formation of the textile technology system.

Study on the Relation between the Linked-Pearl Pattern and Weaving Technology in Ancient China
Authors: Li Bin , Li Qiang
Published: September 2011

The linked-pearl pattern on fabric is a key to study on the transformation of the technique from weaving warp-faced patterns to weft-faced patterns in ancient China. However, the previous studies on the linked-pearl pattern on fabric were not very clear, and led to much misunderstanding. Some researchers believed that Chinese weavers did not master the technique of weft-faced patterns until Persian merchants introduced the brocades with a pattern featuring stringed ball into China along the Silk Road. Based on the studies on historical materials and archeological discoveries of the linked-pearl pattern on fabric, we hold that there are positive connections among the linked-pearl pattern, the technique of weaving weft-faced patterns and the draw loom. The dissemination of the linked-pearl pattern prompted the development of pattern design and the wide application of weft-faced pattern on fabric, even the invention of the draw loom which accelerated the development of textile technology in ancient China.

The structures and properties of the copolymers were investigated by FT-IR spectroscopy and Ubbelohde viscometer, DSC and TGA. Some properties of the copolymer fibers such as breaking strength, breaking elongation and elasticity were also measured. The result demonstrated that the adding of BA can effectively reduce the inherent viscosities of PEIE. Especially the breaking strength, elastic recovery and heat stability of the fibers are improved obviously when adding 1 % (of the multiblock copolymer weight percentage) BA end capping agent.

Published: September 2011

In this work, polyacrylonitrile (PAN) with nanoporous structures were successfully prepared via electrospinning technique. For the preparation of porous PAN nanofibers, two kinds of polymers of PAN and polystyrene (PS) were used as electrospun precursor materials, and then the bicomponent nanofibers of PAN and PS were extracted with chloroform to remove the PS in the composite polymer nanofibers. Electrospinning of PAN with 0-50% w/w at a 15% w/w total concentration in N, N-dimethylformamide produced fibres with decreasing averaged diameters from 500 to 1500 nm. Evidence of phase separation between PAN and PS in the bicomponent fibres was indicated by the characteristic PAN and PS peaks by Fourier transform infrared (FTIR) spectroscopy

Published: September 2011

The PET/PTT self-crimp filament appears obvious crimp elasticity under appropriate finishing conditions. The paper discusses the properties and structures of the PET/PTT filament at different temperatures. With the rising treatment temperature, the shrinkage of PET/PTT fiber increases, while its crimp elongation decreases; both the sonic orientation factor of PET/PTT fiber and the crystallinity of PET and PTT component in PET/PTT fiber decrease. The sonic orientation factor of PET fiber and PTT fiber decrease, their crystallinity increases with the rising treatment temperature. The decrease of the crystallinity of two components makes the orientation lower, which leads to the results that the length of the fiber shrinks and the shrinkage is higher than the crimp shrinkage from the shrinkage difference of two components.

Published: September 2011

Rheological properties of blend spinning solution of sodium alginate and carbon black (SA/CB) were investigated. The results reported that blend spinning solutions were non-newtonian fluids. The apparent viscosity and structural viscosity index increased with increasing CB content in SA spinning solution, but the non-newtonian index decreased, both demonstrated the blend solution was sensitive to shear rates. Blend spinning solution with 6% CB had large flow activation energy (Eη), so the temperature must be controlled exactly in spinning. Temperature had similar impact on sample spinning solutions: the apparent viscosity decreased when it increased. Study on dynamic rheological behavior shows SA/CB blend spinning solutions had greater die swell ratio and worse flowability than pure SA solution, but the flowability of blend solutions could be regulated by changing temperature.

Wool fiber was firstly pretreated by nano-SiO2/Ag antibacterial agent, and then dyed with an acid dyes at low temperature by ultrasonic dyeing. Many factors had an important influence on the dye ability and the antibacterial behavior during the dyeing process of antibacterial wool fiber. The experimental results indicate that the dye-takeup rates of antibacterial wool fiber were enhanced with the increase of the concentration of nano-SiO2/Ag, the dyeing temperature, the dyeing time and the ultrasonic frequency (less than 60Hz). However, the antibacterial ratios of wool fiber were declined in the impact of these factors other than the concentration of antibacterial agent.

Published: September 2011

1-Butyl-3-methylimidazolium chloride ([BMIM]Cl) was applied as solvent to dissolve the cellulose diacetate (CDA) directly. The solution rheology of CDA in [BMIM]Cl was investigated by steady shear and oscillatory shear measurements. In the range of the concentration and temperature studied, CDA/[BMIM]Cl solutions showed the typical shear-shinning behavior and the viscosity decreases with increasing temperature. Compared with the cellulose solutions in [BMIM]Cl, the smaller apparent viscosity of CDA/[BMIM]Cl was shown, which mainly resulted from the weakened interaction between substituted cellulose chains and ionic liquid. The deviation of Cox–Merz rule with steady shear viscosity smaller than complex viscosity in the whole deformation rate range we studied indicates that entangled CDA/[BMIM]Cl solutions are not homogeneous solution systems.

Published: September 2011

In this paper, Wide Angle X-ray Diffraction (WAXD), Small Angle X-ray Scattering (SAXS), Dynamic Mechanical Analysis (DMA) and mechanical testing were employed to characterize the effect of heat treatment under constrained condition on poly(ethylene terephthalate) (PET) fiber. The microstructure and property of the PET fiber with moderate tenacity changed with the heat treatment temperature from 110 °C to 190 °C. No change happened in the crystalline phase while the micro-crystal formed in the amorphous phase from the result of crystalline parameters, which led to the increase of Tg of the fiber. The decrease of the tenacity is due to the decrease of the amorphous orientation and the decrease of the long period leads to the increase of the stability of the fiber.
