Abstract: Silk fabric specifications database system was founded with Visual Basic.NET as operating language and SQL SERVER 2000 as management system. In the paper, we proposed the indicator of selvage warp coefficient, and quantified the relationship between inner warp density and selvage warp density. Then, discussed the regularity of selvage density of 12 species of fabrics by software program which can automatically select the information of the silk fabric from the database.The conclusion provided a theoretical basis for the development of new species silk fabric.

Abstract: Distance fabric is a new structure textile characterized by its two parallel skins of 2D fabric integrally connected by large numbers of the through-thickness threads. The paper explores the principle of distance fabric forming and the weave structure developed by us, and introduces the weaving process in detail and also discusses some problems which should be emphasized in weaving this new structural textiles. The weaving practice indicates that the new theory of producing distance fabric is feasible.

Abstract: In 1994，China’s export amount of textiles and garments reached 35.55 billion US dollars, which turned China to be world’s largest export country of textiles and garments. After being ‘World No. 1’ for more than ten years, Chinese fashion companies shouldn’t only restrict to OEM model. With the development of global economic integration, more and more international fashion brands are pouring into China to take hold of Chinese market. But for international market, most Chinese fashion companies appear to be nervous. However, some Chinese fashion companies have implemented internationalization strategy and reached first base. Combining the fashion brand --TANGY collection, which is under Shenzhen Liangzi Fashion Industrial Co., Ltd, this paper mainly discusses the implementation of its internationalization strategy.

Abstract: National traditional crafts are a treasure-house of rich heritage, and traditional culture with Chinese style and folkloric becomes attractive in recent years, then the innovational combination of traditional elements and modern fashion is the only way towards further industry development. Meanwhile, as one kind of special traditional embroideries, the art and process characteristics of Najin meet the requirements of jacquard weaving. On the basis of jacquard-weaving embroidery, this paper designs Najin style fabrics, in which the ground yarn is grounded on openwork weaves, and embroidery based on weft whole float long as well as the principle of space mixed color. Applying elements of paper-cutting arts in pattern design with Najin’s horizontal, vertical and inclined changing, a richly innovative design is developed. While proving the feasibility of jacquard-weaving embroidery, this paper also provides promising future for the fading Najin culture.

Abstract: This paper proposed a new method based on secondary encoding technology to recognize the pattern of woven fabric. The method disposed the information of both the top and bottom fabric images. The result of analyzing the regularity of the intensity variation of the horizontal and vertical direction of image can be used to determine the interlacing position of yarn sections. The secondary encoding technology coded the color information of both sides of fabric image, then the types of cross points can be determined. After getting the color information of fabric on the warp and weft direction, the color pattern could be obtained, and it can be used to correct the errors of classification of cross-point classification. Finally a fabric model can be built which contains types of interlacing points and color pattern.

Abstract: Research on structural design of grey simulative effect jacquard fabric is the key to obtaining nice grey shading effect of fabric. In this paper, by merging the characteristics of traditional manual design method and the application of digital design technology, a design method of grey simulative effect jacquard fabric were introduced with design illustrations, and this study is carried out to analyze the relationship of structural design and fabric effect via increasing a new grey layer. Differs from the effect of traditional grey simulation jacquard fabric, the design innovation of grey simulative fabric are capable of producing black-and-white simulative effect accurately and meeting the technical requirements of mass production for achromatic jacquard fabric. It provided a new design concept for digital jacquard creation.

Abstract: Hemp fiber has many excellent properties, but there are certain difficulties in spinning yarn because the fiber is hard and its cohesion is small. Cotton fiber is soft and its length, fineness is uniform therefore has excellent spin ability and can compensate for the shortage of hemp fiber. We developed the knitted fabrics that have moisture absorption and dry-fast properties using the hemp/cotton blended yarn and discussed weft knitting, dying as well as finishing processes. This shell fabric has special performance such as moisture absorption and air permeability, anti-mildew and antibacterial, anti-ultraviolet ray, antistatic, ecological health ect, which is the ideal sports and summer fabric.

Abstract: Carbon nanofiber for various applications is being actively investigated while the thermal properties of carbon nanofiber mat with different fiber diameters are not well known. In this paper, carbon nanofiber mats with diameter of 220~1000nm were fabricated via electrospinning method. Then the effects of polyacrylnitrile solution concentration, supplied voltage, and spinning distance on fiber diameter were studied. According to the results of thermal properties measurements by laser flash technique, the carbon nanofiber mats possess great potentials in applications for thermal management materials.

Abstract: Fiber-reinforced plastic is attractive as a material that can replace metal. It has been widely used in various engineering fields involving aircraft, ships, and automobiles. Currently, personal safety is an important automobile issue. Improvements in pedestrian safety technology, particularly, are required in order to improve vehicles' impact-absorbing performance. In this study, materials with good impact properties that are lightweight and easy to design with will be considered. In other words, a composite is required that has high toughness and high fracture energy while not being brittle. A method for evaluating the compressive strength after impact using a compression after impact (CAI) test has been adopted. New hybrid FRPs that are lightweight and have good impact properties can now be developed.

Abstract: In this paper, development situation of flash-spinning is reviewed briefly. The technology process, principle of phase separation and supersonic flow are described in detail. The characteristics and applications of flash spinning nonwovens are described, and its products have potential development and wide prospect of market.
