Learners enrolled: 467
The course in specially designed for PG students, teachers and professionals.Testing of functional and technical textile materials is an extremely important activity forproduction, product and process development, research and application.During selection of textile materials for their functional and technical applications the testing ofdifferent performance characteristics is necessary. To meet up the customer requirement,specification is very useful. In this concept, testing plays a vital role.In research and development field the evaluation of textile materials helps us to decide the nextroute. Research Institute, pilot plants can achieve process development through testing or exactinvestigation into better, cheaper and quicker methods.Certain standard level should be maintained to control the production process. By evaluation oftextile materials one can easily detect the faults of machinery and materials. Continuous test ofthe textiles results an enhanced and efficient output of the production.The course deals with the detailed testing methods and analysis of low stress mechanical andtransmission (heat and moisture) characteristics of functional textiles. Also, detail and specifictest methods of various technical textile materials, like extreme heat, fire and cold protectiveclothing, geotextiles, filter fabrics, fibre reinforced composites, electromagnetic shieldingtextiles, compression bandages, ballistic protective textiles, UV protective textiles, and analysisof test results have been discussed in details.
