Proceedings of 57th Joint Technological Conference Four leading textile research institutes in India viz. BTRA, Mumbai, ATIRA, Ahmedabad, SITRA, Coimbatore and NITRA, Ghaziabad have been organising Joint Technological Conferences over the years. In this annual event, latest finding of the research programs with reference to the latest technological developments are disseminated. In this context, 57th Joint Technological Conference was held at BTRA, Mumbai on 17th and 18th February, 2017. Nearly, 300 delegates from industry, trade and academics participated in this conference. The highlight of this conference was one full day on ‘Geosynthetics’, under the sponsorship of Textile Commissioner’s Office, Ministry of Textiles, GoI and the other day was devoted to R&D in Emerging Areas, Protective Textiles, Product Development, Eco-friendly process, etc. related to traditional textiles. The event was inaugurated by Dr. Kavita Gupta, Textile Commissioner, Ministry of Textiles, GoI. Dr. Kavita Gupta, in her inaugural address, said that in India only 10% of textile products belong to technical textiles as compared to developed nations such as Germany where 50% of textile products belong to technical textile category. Current market size of technical textiles in India is Rs. 1 lakh crore and the market is growing at 20% CAGR. In order to grow in high value technical textiles segment, we should focus on research that is demand based and market driven. Chief Guest Dr. Kavita Gupta, Textile Commissioner, Ministry of Textiles, GoI. lightening the lamp Moreover, ability to translate research output in to commercialisation is the need of the hour. She stressed the importance of the link between academia and the industry. Dr. Anjan K. Mukhopadhyay, Director, BTRA welcomed the dignitaries and the delegates. Dr. Anjan K. Mukhopadhyay, Director, BTRA welcomed the dignitaries and the delegates. He briefed the audience about this conference profile and said that one full day was devoted to ‘Geosynthetics’ that could open up an avenue for the conventional textile manufacturers to interact with Geosynthetics manufacturers/users to know the opportunities available in terms of machinery, processes, etc. to make technical textile products, especially geosynthetics. He also said German Textile Machinery Manufacturing Companies have also taken part in this conference by way of presentations on needle-felt nonwoven and latest machine innovations on treatment of Geotextiles. Mr. Narendra Dalmia, Deputy Chairman, Governing Council, BTRA presided over the inaugural session. In his presidential speech, he talked about the research projects of all four TRAs currently in progress and their findings as well as the operational performance. He said that innovation is the key word and this is where the Research Associations play an important role and appreciated excellent work done by all the four TRAs to help the industry in its goal to have better operational efficiency. Mr. Rajesh Nath, the Managing Director for VDMA in India made the Key note address introducing VDMA, Textile Machinery and the solutions and competence of VDMA members also in the area of machinery, plants and components for geotextiles applications. This year, VDMA completes 125 years with its presence in Germany. With the theme of the event being Geotextiles, he spoke about Geotextiles being ambitious textile products that are tailor-made according to the intended application. Depending on application, the soil quality has also to be considered when choosing geotextile material. Nonwovens, woven and warpknitted geotextiles, geogrids, of all geotextiles used around the world, nonwovens were estimated to make up over 65 % in terms of area. In order to produce tailor-made geotextiles, appropriate machinery is needed and VDMA can guide the industry to the right manufacturers as per the requirement. Dr. C.R. Prayag, Officiating Director, ATIRA proposed vote of thanks.
