NITRA handles projects on Protective Textiles
Technical Textiles is fast emerging as the most potential segment of textile industry in these days. Realizing this fact the Ministry of Textiles has asked NITRA and IIT Delhi to set up a Centre of Excellence (Protech) at NITRA with NITRA as lead partner. The centre will have complete infrastructure facilities to help the entrepreneurs. The process of procuring equipment for setting up the fire testing laboratory is in full swing to make the centre at NITRA operational by end 2010.
Northern India Textile Research Association (NITRA) has signed an agreement with Bolton University, UK to conduct collaborative research in the area of Protech. In the same line of exploring potential for technical textiles, the MoT has awarded NITRA three projects on protective textiles for the year 2010-11. The project titles are Development of cut resistant & abrasion resistant protective textile by using composite metallic yarn, Developing shield of corn fabrics for enhancing the protection from flame, and Developing armor using himodulus polyethylene (HMPE) fibre. Scientists at NITRA have already started working in the above projects. In this particular issue and forthcoming two issues of NITRA e-Bulletin, we present before you the brief highlights of the said projects.
The stainless steel yarns are highly cut resistant, abrasion resistant, and electrically conductive and are suitable for making protective garments such as cut resistant & abrasion resistant gloves, aprons, smocks, jacket, trousers leggings, socks or stockings, automobile sheet covers, other home furnishing products etc. A wire and wire cored metallic yarns are quite difficult to knit & weave into protective garments and the garments produced are generally bulky, stiffer and heavy. That is why the wire metallic products have limitations at many places to form garments.
Hence the composite yarn made out of non metallic yarn and metallic yarn makes it possible to produce protective textiles. The composite yarn comprises a core of metallic yarn and wrapping of non metallic fiber or yarn applied on it. The protective Textiles made out of composite yarns show high cut resistance, high strength and high abrasion resistance.
Polyamides such as nylon fibers are preferred as sheath materials in a composite yarn for their economy, ease of use and good abrasion resistance. Other fibers like cotton and polyester can also be used as non metallic yarns to add comfort properties. This is considered that the protective textiles made from composite metallic yarn will be the best solution to overcome the cut resistance problems in various public places for seat covers, home textiles for carpets, curtains, table covers etc. and for protective clothing like jacket, gloves, trousers.
