Abstract: In order to study the effect of different blended ratios on strength and elongation properties of Outlast/viscose blended yarn, ten kinds of blended yarns had been designed and spun. The blended ratios were Outlast/viscose 0/100, 15/85, 25/75, 30/70, 35/65, 40/60, 45/55, 50/50, 60/40, 100/0. By testing the strength and elongation properties of the blended yarn, the effect of blended ratio on blended yarn’s breaking tenacity and elongation rate was analysed. The results showed that, with the increase of blended ratio, the breaking tenacity and breaking elongation rate of the blended yarn both presented a downward trend. But when Outlast/viscose blended ratio was 35:65, breaking elongation rate had a maximum value. When blended ratio was 45:55, breaking tenacity had a maximum value, which should be used in practice.

Abstract: Alginate fibres are difficult to spin on the traditional ring spinning machine. Friction core-spun yarn which took alginate fibers as main wrapped fibers and cotton yarn as core yarn were developed on DREF-Ⅲ. The influence of main spinning technical parameters, such as spinning speed, friction roller speed and core yarn percentage, on the yarn performances was studied by means of orthogonal experiment and the optimized technical was put forward. The results showed that the overall performance of the core-spun yarn would be better as spinning speed of 100 m/min, friction roller speed of 4000r/min, core yarn percentage of 50% respectively.

Abstract: The garment materials are one of important factors of affecting thermal comfort of garment. Moisture absorption & quick dry fiber have high-performance of moisture absorption and diffusion. In the paper, the thermal comfort of garment made from moisture absorption & quick dry fiber is studied by wear trial. The subjective and objective methods were used to evaluation thermal comfort of garment. Experiment shown that Experiment shown that moisture absorption & quick dry garment can improve person’s thermal comfort while the microcliamte of garment is small. The moisture absorption & quick dry garment have no obvious advantage to improve thermal comfort of garment while person is static situation or garment size is much big.

Abstract: “Shoso-in” is located behind the Hall of Great Buddha of Todaiji Temple in Nara city of Japan and it is known to the world with its storage of cultural relics of successive dynasties, most of which are valuables handed down from Japan’s royalty, nobility and Buddhist assembly in Nara and Heian periods of Japan. At that time, Japan's central government, princedoms, regional governments, including many large monasteries, had the establishment of “official warehouse”, which served as the main storehouse for storing rice expropriated by the state as well as silk, iron products and other property and the various storerooms were divided into different blocks to form “Shoso-in”. Today, only the Shoso-in of Todaiji Temple stands the test of the long history and others have disappeared. Since the 8th year of Meiji Period, Shoso-in broke away from Todaiji Temple and is under state administration and Japan government ordered to permanently conserve the “treasures” inside. Since then, Japan Shoso-in become an authentic independent “museum”. Shoso-in in Japan is greatly favored by the world, firstly because that it boasts a history of more than 1200 years and is blessed with a great variety of collections, most of which are donated by royalties; secondly because that since the 30th year of Showa when Shoso-in in Japan is relocated from old treasure-house to the newly-structured treasure-house, the cultural relics are better protected. According to the literatures, the collections conserved in Shoso-in almost stand intact and this is rare in the history of world conservation, facilitating the investigation and repair work of researchers.

Abstract: This thesis mainly aims to develop the database application system for elements of ethnic apparel based on present –day garment design theory in the way of conducting an abstract and classified summary of the ethnic apparel elements whose digitization expression realizes the desirable functions such as retrieval, scan, result display and process, information management and so on. And this database application system is not only an information carrier for cultural heritage for ethnic apparel, but also treasure-house for contemporary garment design.

Abstract: In order to obtain paraboloid shape fabric, this paper focused on the fabric structural design method suitable for modified traditional loom weaving. Defining the shape and length of parabola of paraboloid fabric by calculate. Analysised the principle of paraboloid fabric forming by researching the shape of infinitesimal body at different part of paraboloid fabric, obtained the shape of infinitesimal bodies meet the requirements of paraboloid fabric forming. A paraboloid fabric was woven and the designed structure was obtained.

Abstract: As one of the most abundant renewable resources and natural polymer materials, cellulose increasing peoples attention in many fields. In this paper we was firstly focus on the solubility of the wooden cellulose and cotton cellulose in NaOH/Thiourea/Urea solution, the result showed that the solubility decreased with the increase in concentration of cellulose. Then the morphology test by a polarizing microscope and the rheological properties was tested by a viscometer, both of the two different cellulose solution present the shear thinning property. Finally the experiment achieved a comparison of the solubility of two different celluloses, and the cotton cellulose presents a better solubility in this NaOH/Thiourea/Urea system.

Abstract: As a key stage in wet spinning, compacting process served as a connection between spin and post treatment, it has significant influence on the performances of polyacrylonitrile (PAN) fiber. In this paper, the influences of temperature, time and tension on the compacting process and performance of fibers were studied. The test shows that the suitable compacting process condition is 110°C for 90s with a higher shrinkage ratio. With increasing shrinkage ratio, density and breaking elongation raise, but orientation and breaking strength decrease. To obtain better effect of compacting process, loss of orientation and breaking strength can hardly be avoided; it can be compensated by secondary draw in post process.

Abstract: Outlets is a relatively new format in China, and the development history is relatively short.In order to understand and know better about Outlets, meanwhile to give Outlets some certain exploration and guidance about its development in China, an overall and thorough field survey in Beijing Yansha Outlets, Shanghai Qingpu Outlets and Shanghai Songjiang Fox Town Outlets was made, Depending on the detailed original research data and the analysis in multiple perspectives, the Outlets brand discount marketing condition in China and development pattern discussion were systematically expounded to expect providing powerful reference for corporations and individual who are concerned about Outlets brand discount marketing retail formats development.

Abstract: To find out the effect of the electrostatic web-cleaner installed on the front plate of carding machine on card sliver quality, the sliver produced under different voltages and gauges of electrostatic plate was tested with Uster AFIS. The results show that card sliver quality can be improved when the gauge and voltage are appropriate. When the gauge is 1 mm, parameters of short fiber content, nep content, impurity content are better at a voltage of 1500 V than those of other voltages; when the gauge is 2 mm, a voltage of 500 V or 3500 V is advantageous to improve the comprehensive quality of card sliver (except for impurity content parameter); when the gauge is adjusted to 3 mm, the impurity content is decreased at 1000 V and the nep content is decreased at 2500 V, but the improvement on card sliver quality is not perfect.
