For reducing the cost of production and saving the environment, the utilization of chemicals, energy, and processing time should be minimized as much as possible. In this study, antimicrobial ﬁnishing of wool ﬁbers was achieved by synthesizing Ag/Cu2O/ZnO nanoparticles (NPs) in-situ on the surface of wool ﬁbers, and subsequently dyeing with two natural dyes extracted from Pomegranate peels and Walnut Green husks.

A Research Brief by the Center for Global Worers´Rights (CGWR) draws from responses from an online survey of Bangladesh employers, administered between March 21 and March 25, 2020, to document these trends. It reveals the devastating impact order cancellations have had on businesses and on workers. Crucially, it illustrates the extreme fragility of a system based on decades of buyers squeezing down on prices paid to suppliers: factory closures, unpaid workers with no savings to survive the hard times ahead, and a government with such a low tax revenue that it has very limited ability to provide meaningful support to workers and the industry.

“Industry 4.0” is the new buzzword becoming very fashionable, and hence, considerably over used. The credit for coining this iconic word goes to Siemens at the Hanover Messe in 2015. Industry 4.0 – also termed as the 4th generation of the industrial revolution – marks the beginning of a new era. It essentially represents the digital transformation of traditional industries like manufacturing to intelligent factories with the advancements in automation, advanced materials, 3D printing, artificial intelligence, augmented reality, cobots (collaborative and robots). Adaptive and ergonomic production lines, intelligent robots and integrated energy systems – all parts of Industrial Internet of Things (IIoT) – are increasingly making it possible for companies, in practically every industrial and manufacturing sector, to digitize their operations. This digital transformation is enabling them to become 24×7 connected intelligent factories. The computerization of traditional industries, like manufacturing, i.e. their transition to intelligent factories, is going to be the key to their survival in a couple of years from now.

Medical textile is an important product category within technical textiles. Technical textiles are non-commodity textiles which are predominantly used in non-apparel applications such automotive textiles, medical textiles, geotextiles, sport textiles, to name a few. Even in this tighter economy, technical textile is a fast growing one. According to recent report by US-based Industrial Fabric Association International (IFAI), the specialty fabric industry expected to grow about 2.5%. Jeff Rasmussen, IFAI’s market research manager opines that with the global GDP growth edging towards 4%, the specialty fabric industry is expected to maintain a growth rate of about 2.5%.
Most recently, a UK based Textile Media Services has estimated the global value for technical textiles to be about US$127.2 billion. More importantly, in 2010, China consumed technical textiles worth about US$29 billion. Besides, India is projected to have a double-digit growth of over 15% per annum in technical textiles sector.
A recent report by the Associated Chambers of Commerce and Industry of India has estimated the market size to about US$20 billion. The government of India is also supporting the growth of technical textiles sector in India by creating a National Technological Mission on Technical Textiles (NTMT) with a budget outlay of US$40 billion, and medical textile is an important part of this NTMT. To promote the growth of medical textiles in India, the government has established a Center of Excellence in medical textiles at the South India Textile Association located in the textile city, Coimbatore, in Southern India.

Continuous weavable multifunctional carbon nanotube yarns are fabricated at one-step by spinning from a catalytic chemical vapor deposition reaction. The CNT yarn is formed through the direct assembling of carbon nanotubes in the gas flow as continuous integrated by mechanical winding. Kilometers of high-quality continuous yarn are spun from this process through the design of the CVD reaction with innovative spinning methods.

It is already well known that there are numerous environmental and political reasons to move away from fossil fuels and towards alternative energy solutions. Solar energy has been regarded as an ideal alternative energy and has great potential for satisfying future energy demands. In this key-note lecture, it will be presented that the fundamentals of dye sensitized solar cells (DSSC) including history and background, energy harvesting cycle, principles of DSSC, and solar cell operation. The lecture then discusses the next generation technologies to improve the effic-iency of DSSC. Finally, this lecture introduces some research results performed by author with his graduate students. Dye-sensitized Solar Cells(DSSC) are a believable alternative to conventional silicon solar cells because of their ease to fabrication, low-cost compared with other photovoltaics and wide applications.
