  • Flexible devices have been developed from their rigid, heavy origins to become bendable, stretchable and portable. Such a paper displays, e-skin, textile electronics are emerging research areas and became a mainstream of overall industry. Thin film transistors, diodes and sensors built on plastic sheets, textile and other unconventional substrates have a potential applications in wearable displays, biomedical devices and electronic system. In this review, we describe current trends in technologies for flexible/wearable electronics.

  • Liberalization may be described as the opening up of the economy to the outside world by relaxing government trade and economic policy restrictions to allow imports. In Kenya, this took place in the early 1990s and it had negative and positive effects on businesses manufacturing and retailing clothing and textiles. This case study narrates what has happened over the last 20 years to businesses in Nairobi, Kenya dealing in clothing and textiles. Some of the original businesses have closed down and been replaced by new ones. More small scale Kenyan businesses have been started dealing in clothing imports from the East and West selling both new and second hand clothes. There has been increased employment in the small scale clothing and textiles sector in garment making and retailing. All in all, liberalization has forced large and medium scale textile manufacture to change strategy so that they target selling to the export market more than to the local market.

  • The objectives of this paper are to examine some of the factors which may account for the rise in predominance of British textile manufacture in the eighteenth and nineteenth centuries. This paper identifies a range of important eighteenth century British inventions and associated developments, such as the 'factory' system, which stimulated expansion in textile manufacture in the British Isles and led to the rise in international importance of various 'heritage textile industries', including the Lancashire cotton industry, the Yorkshire woollen and worsted industry, the Dundee jute industry and the Irish linen industry.

  • This study was carried out with the view of fundamental investigating to improve the tactile and the hygroscopicity of Poly(ethylene Terephthalate) (PET)fibers. Mono-sodium ethylene glycolate in ethylene glycol (MSEG-EG) solution was prepared and PET films were treated with it. The following conclusions were obtained. When PET films were decomposed in MSEG-EG solution, decomposition rate constant showed an exponential relationship with treating temperature; activition energy was 23.30 Kcal/mol, activation enthalpy was 22.52~22.60 Kcal/mol and activation entropy was -29.20~ -29.41 e.u. On the basis of the results obtained above and structure identification of decomposition products, it was found that the decomposition reaction proceeded through ester interchange reaction.

  • In this study, the effect of innovativeness of external networks on the corporate innovativeness and innovation performance were explored based on web survey data collected from 230 manufacturing companies. Specifically, according to the manufacturers' business categories divided by the technology level, three groups such as advance technology (electronic/IT), mid- to high technology (automobile/machine), and low technology (textile/clothing) companies were investigated to find out which external network influences corporate innovativeness and innovation performance. In the result, textile/clothing companies were not different in company size, history, and innovation effort from advanced technology and mid- to high technology companies. Collectively, the innovativeness of external networks affected corporate innovativeness and innovation performance. In the result by a business category, innovativeness and innovation performance of textile/clothing companies were affected by the innovativeness of competitors, whereas automobile/machine companies in the mid- to high technology group were affected by suppliers. In addition, advanced technology (electronics/IT) were affected by buyers and competitors. These differences suggest that the way to use vertical networks toward upstream (e.g., suppliers) and downstream (e. g., buyers) as well as horizontal networks toward competitors can be different by the business category of manufacturers. The result would provide implications for the academia and the industry.

  • Printing process has been a major sector in the textile industries for a long period of time. With the advent of digital textile printing, the complex procedures of printing preparations and after-treatment processes have been streamlined. For the design of the motives of images to be printed, the use of image handling software, e.g. Photoshop(Adobe), has been of prime importance. Even though the software is extremely useful and functionally versatile, there are many laborious steps involved for the specific textile printing process. The use of a CAD-based textile printing function may help the textile printing process in streamlining the complex processing stages. The image qualities of the output designs have been compared objectively with the aid of several image similarity evaluation schemes including the SSIM, and FSIM Index methods.
