Textile Engineering / CUPRO - What is Cupro ?
« on: May 20, 2018, 12:42:54 PM »
Cupro is commonly known as a Japanese based developped material. - It is a kind of Rayon (Viscose ) group of Fibres.
It is more like Liocell , it is reprocessed cellulose. It is made from regenerated cellulose fiber .
Cuprammonium, gives the name to the fibre Cupro , it is used in making of process the wood pulp which is the base material. With the process, the wood pulp is dissolved in an ammoniac copper oxide solution.
Cupro fabric breathes like cotton, drapes beautifully, and feels like silk on your skin. Its slinky, curve-hugging drape makes it great for elegant dresses and blouses.
What is Cupro ? : Cupro is a regenerated cellulose fiber, soft, strong and silky, produced by treating cotton cellulose with cuprammonium salts. It is also called Cuprammonium Rayon. Cupro was first made in 1890s in Japan and Italy.
Trade names are used within the rayon industry to determine the type of rayon used: • BEMBERG, for example, is a trade name for cupramonium rayon that is only produced in Italy. • MODAL is a widely used form of rayon produced by Lenzing Fibers Corp. which is based in northern Austria. Galaxy, Danufil, and Viloft are rayon brands produced by Kelheim Fibres, a German manufacturer. • GRASIM (India) is the largest producer of rayon in the world (claiming 24% market share). -

Textile Engineering / Safety in the workplace has become a major priority in Bangladesh
« on: April 01, 2018, 02:11:06 PM »
Bangladesh RMG industry is advancing positively. Safety in workplace is a major priority for the industry. A training program has been launched for some eight lakh readymade garment workers in Bangladesh. This training is expected to contribute greatly to that goal as both workers and employers will benefit from improved safety practices. In Bangladesh the readymade garment industry accounts for 80 per cent of exports and, as a result, is of paramount importance to the economic health of the country. Despite its economic importance, or perhaps because of it, enforcement of building codes for factories has historically been lax, leading to an entire industry rife with unsafe working conditions.
The lack of fire safety was well known due to a long record of fatal factory fires, including a fire in late 2012 that killed 112 workers. By early 2013, several international retailers with supply chains based in Bangladesh factories had already embarked on fire inspection programs, but until the Rana Plaza tragedy no one considered structural safety to be a fundamental concern.

Textile Engineering / Employment in RMG factories
« on: March 24, 2018, 12:24:38 PM »
All workers must be given appointment letters
A survey carried out by the Mansusher Jonno Foundation has found that more than 72 percent of garment workers do not have any appointment letters. The survey covered 770 workers in Dhaka, Chittagong, Gazipur and Narayanganj, and found that the bulk of these workers could only produce their identity cards as proof of employment. This comes as a surprise as it is mandatory for BGMEA and BKMEA factories to provide appointment letters to workers employed by member companies.
Things have improved in a lot of ways in the sector after the disastrous Rana Plaza incident. The Accord and Alliance initiatives have worked with the sector to improve safety standards and make the RMG sector better in many ways. However, as the latest survey shows, management practices, when dealing with workers' basic rights still need a lot of improvements. Most workers have no idea about the existing provisions of the labour law, and given that there no trade union in these factories the RMG owners have no central bargaining agent. Hence, they cannot present their demands coherently to their employers.
This is an area that policymakers need to look into. While it is an undeniable fact that the garments sector provides the bulk of our exports earnings, it is also true that RMG workers have serious grievances about the threat of sudden termination. The government should form a separate monitoring cell to oversee that workers are given all necessary documents to establish their bona fide as entitled under the law.

Textile Engineering / Skin line fabric developed by Stanford scientists
« on: March 24, 2018, 12:09:11 PM »
Recently skin-like fabric material that cools the body more efficiently is developed by a team of multidisciplinary researchers at Stanford University.
Science journal, the researchers from Stanford report that they used nonporous polyethylene to develop a textile material which aides radiative cooling while maintaining breathability, wicking and necessary mechanical strength.
According to the report in Science, the researchers have also devised an instrument to simulate skin temperature. The use of nonporous polyethylene fabric resulted in the lowering of skin temperature by about 2.7 degree centigrade when compared with another commonly used next-to-skin fabric.
According to Yi Cui, an associate professor of materials science at Stanford and the lead author of the study, the fabric effectively cools the person, which makes cooling the building unnecessary thereby saving energy.
Nonporous plastic textile transports the body heat as infrared rays due to the nanostructured polyethylene. Researchers modified the polyethylene material that is commonly used in battery development which enables it to be opaque to visible light but transparent to infrared rays so that the heat can be dissipated.
According to Professor Shanhui Fan, professor of electrical engineering at Stanford, who co-authored the study, this research can lead to the development of new materials that can trap or let go infrared radiations.
The research is multidisciplinary one involving photonics, nanotechnology and chemistry. Indeed, it shows that new developments in advanced textiles can come from schools that are nontraditional textile strongholds, reflecting the nature of the next phase of textile research and development.

Textile Engineering / Present trend of textile education in Bangladesh
« on: March 21, 2018, 11:23:01 AM »
Bangladesh is the world 2nd largest apparel exporters. Our economy is largely dependent on the textile and RMG sector. For meeting the huge demand of manpower in textile and RMG sector the textile educational institute is raising at an alarming rate. However, unfortunately it is true that there are many foreigners from India, Pakistan, Srilanka working in our county and we have to pay a lot to them. If you visit the international textile job portals you may find how Bangladesh is a lucrative place for the Indians and Pakistanis! It is a misfortune for us that our largest contributing sector on GDP is largely dependent on the foreign experts. In some extent the factory management are bound to recruit foreign expert and also in some cases they recruit just for adding value and making the factory attractive to the buyers. Now, it is a demand of time to produce international standard experts in textile fields. Here international quality experts do not means to be sound only in technical aspects. It is true that the factory management recruits textile engineering not to make technical experts but to make a very good manager. And after a certain period the engineers are need not to solve the technical problems any more but he must has a very transparent knowledge on the products costing, manufacturing plan, product quality, time management and most importantly profit of the factory. This is why in textile sectors textile experts are badly needed. So from the above discussion we learnt that our main problems is in lacking of international standard textile experts. Now if we thing that we will solve the problems by producing graduates as many as we can then only it will decrease their value in job market and the demands of international standard textile experts will not mitigate any longer.

Textile Engineering / India to Produce Less Cotton than Earlier Expectations
« on: March 21, 2018, 11:20:32 AM »
Pink boll worm infestation is influencing the cotton production in India, this year (October 2017-September 2018). Since the December 2017 estimate, cotton production has been revised downwards due to crop damage in some major cotton growing states.
Mumbai-based Cotton Association of India (CAI) estimated that this year’s cotton production would be 36.2 million bales (170 Kgs each) as against its December estimate of 37.5 million bales. Lat month, CAI estimated the crop to be 36.7 million bales. Speaking via telephone in the early hours of today, a key market watcher in India stated that the lower estimate was expected as the governments of Maharashtra and Telangana advised cotton farmers to remove the plants in January to avoid furthering and spreading of pink boll worm infestation to save Rabi and subsequent Kharif crops.
While the infestation has been serious in some major southern states, proactive measures taken in Gujarat and Northern states after 2016-17 infestation the issue has been less serious there. Cotton experts have requested cotton growing states to take precautionary measures now so that the issue will be under control in the next cotton growing season.
According to Atul Ganatra, President of CAI, “the lowered crop estimate is mainly due to crop damage because of severe pink boll worm infestation and scarcity of water in some states.”
While the production is expected to be lower, good news is that domestic consumption in India is on the rise due to new spinning mills in Gujarat and other states which has resulted in 3.5 million additional spindles in India.

Textile Engineering / Nano-Care Deutschland AG Develops a Highly Sophisticated Impregnation for Textil
« on: March 21, 2018, 11:20:00 AM »
Nano-Care Deutschland AG , a mid-sized company based in Saarwellingen will offer a coating system for water and oil repellency that aims to revolutionize textile finishing. “Removal of ‘C8 fluorocarbon technology’, which will be banned due to its emissions of PFOS and PFOA, leaves a significant performance gap in the market,” says Oliver Sonntag, Nano-Care Director. “The great challenge for us has been to retain existing high standards of oil repellency – whilst eliminating long-chain fluorination. We have solved this problem by creating a special silicon dioxide backbone.” The result – Nanoflex F-Bond, marketed under the umbrella brand INTELLIGENT HYBRIDS is based on liquid concentrates and is applied using common industrial dipping methods. For many years there has been strong pressure for innovation in the textile finishing sector to meet increasing regulation and ecological demands. As a spin-off from the Leibniz Institute for New Materials (INM), Nano-Care Deutschland AG sees a market potential amounting to the hundreds of millions Euros. “Our particular focus is on military, work-wear and health sectors which have to satisfy especially high performance requirements and currently have only temporary permission to use C8 technologies. Their elimination – particularly outside the European Union – is an important step towards achieving ‘ecological sustainability’ in the textile industry.”
Nano-Care Deutschland AG has been developing innovative coatings for textiles and other surfaces since its founding in the year 2000. On reorganizing its corporate structure at the beginning of 2018, the new Textile Effects’ department will develop further specialization in the sector. Specifically the company partners “private label” clients, be they manufacturers of surface coatings, distributors of chemical products or users of high-tech surface finishes. Currently, companies and consumers in more than 65 countries benefit from their multi-functional performance advantages.
