STUDY OF POLYESTER HIGH LOFT TEXTILES FOR THE ACOUSTIC AND THERMAL INSULATION APPLICATIONS

Textile Technology

In recent times there is new interest for polyester fibre in the light of growing global concern for environmental preservation and control of pollution. Polyester and allied fibres can certainly be considered as a high potential source for new product development. Growing market for polyester fibre based industrial applications offers new possibilities for polyester fibre. In order to meet the challenge in this area, products made out of polyester fibre should adopt new technologies for industrial applications. The potential of Polyester fibres is not at all exploited fully for development of nonwovens, although the mechanical characteristics of these fibres are very encouraging. Polyester fibre automatically becomes eligible for various end uses as it has much higher relative strength, availability, cost competitiveness as compared to other bast fibres for producing cost effective nonwoven products. This thesis work addresses all these aspects in order to have a better alternative way for making products using Polyester fibre. Highloft textiles are one such area in which the Polyester fibre can be used effectively. New processes of making highloft textiles using nonwoven technology will lead to better working conditions. A comparison with the traditional textile production shows, that the new applications are offering also very attractive opportunities to invest and growth for Indian polyester industry. In this research work the polyester fibre was blended with polyester and low melt bi-component fibre and highloft textiles has been developed for various applications and studied. It is found that polyester fibre based highloft textiles possess better acoustic and thermal insulation properties, the developed highloft textiles will surely act as a substitute for synthetic acoustic and thermal insulation products.
