Origin of Qipao Fashion in Early Republic Period

The goal of this research is to analyze and discuss the origin of Qipao as women's fashionable wear in the early Republic Period (1911-1949). The origin of Qipao fashion will be discussed in three aspects; 1) discussion of the original time, place and consumer group of Qipao fashion; 2) analysis of initial style and wear combination of Qipao, 3) deduction of the origin of the name Qipao. Besides, the analysis will also be given about Qipao's aesthetic characters, its production, consumption guarantee as well as its social backgrounds. The research will be made on the basis of the principles and methods of history, social psychology of clothing and design, and will use many materials especially historical writings and publications to give a more detailed discussion.Here are some tentative conclusions. Firstly, Qipao as a kind of one-piece dress was not inherited directly from the robe of Banner Style. It was a new fashion in the 1920s, which combined the elements of long vest called Qipao Majia, Wenming

Comparison of Earnings Power between State Commercial Banks and Stock Banks

As earnings power is one of the primary capacities for commercial banks, by analyzing several indexes on banks‘o peration performance, this article compared the earnings power between the state banks and the stock banks in China. Through the analysis, some problems of domestic banks may be found and pointed out that the commercial bank should stress on the target of profit maximum to avoid the domancial risks. With enough earnings power,the domestic banks can take the challenge with those foreign banks entering domestic money market.     

Estimation of Single-fibre Tensile Properties from the Bundle Tensile Curve of Polyester Fibres

Fibre bundle tensile curves can be used to characterise fibre processing properties and end-use performance directly and to predict single-fibre properties in theory. In this paper, the tensile behaviour of polyester fibre-bundles has been analysed in characteristic values and diagramming. The characteristic distributions which include the symmetry distribution on right part, SRBS‘(e), on left part, SLBS‘(e) and the curve on base-line modification, MBS‘(e),based on the modulus distribution, BS‘(e), as well as thefrequency density function of broken fibres, B‘(e), havebeen derived from the tail of bundle tensile curves. Thetheoretical and measured results show that the mostimportant curves are MRS‘(e) and B‘(e) and can be usedto estimate the breaking-extension distribution of singlefibres. Especially for MRS‘(e), the modulus distributioncan accurately characterize single-fibre tensile propertiesand is no limitation as the calculation of B‘(e) because thebundle specific stress Y(e) of no fibre breaking at extensione should be found at first.     

Measurement of the Average Molecular Weight of Cotton Cellulose Crosslinked by a Polycarboxylic Acid at Different pH Using Multiple Angle Light Scattering Photometer in a DMAc/LiCl Solvent System

Durable press finishing of cotton fabrics with polycarboxylic acid increases fabric wrinkle-resistance at the expense of its mechanical strength. Severe tensile strength loss is the major disadvantage for wrinkle resistant cotton fabrics. Tensile strength loss of cotton fabric crosslinked by a polycarboxylic acid can be attributed to depolymerization and crosslink of cellulose molecules. Measurement of the molecular weight of cotton fabric before and after crosslinked by polycarboxylic acids can offer a possibility of direct understanding of the depolymerization. In this research, a multiple angle laser light scattering photometer was used to determine the absolute molecular weight of cotton fabric treated with BTCA at different pH and then hydrolyzed with 0.5 M NaOH solution at 50℃ for 144 h. The results indicate that average molecular weights of cotton fabric treated with polycarboxylic acids at different pH are almost the same.     

Applications of Neural Networks in Spinning Prediction

Th netal network spinning prediction model (BPana RBF Networks) trained by data from the mill canpredict yarn qualities and spinning performance. Theinput parameters of the model are as follows: yarncount, diameter, hauteur, bundle strength, spinningdraft, spinning speed, traveler number and twist.     

Condensation of Water Vapor on Waterproof Breathable Fabrics

Condensation occurs when the local vapor pressure rises above the saturation vapor pressure at the local temperature in theory. A new measuring apparatus were made to obtain temperature and relative humidity simultaneously for the purpose of investigating the mechanism of condensation occurred on the fabrics. The experiment conducted at the standard condition of temperature of 20℃ and relative humidity of 65%. The result obtained from experiment showed that condensation could occur under the situation closed to saturation line as the temperature on fabric may be lower than dew point of water vapor in the measuring box depending on the experiment conducted at an ambient environment temperature of 20℃ The range of fabrics studied showed that PTFE laminated fabrics except nylon gingham PTFE laminated fabric facilitates the loss of water vapor and therefore prevent condensation. It is necessary to develop studies from a wide range of fabrics, especially breathable fabrics and under bad experiment conditio
