Synthetic Fibers Industry Synthetic fibers are the result of extensive research by scientists to improve on naturally occurring animal and plant fibers. In general‚ syntheticfibers are created by forcing‚ usually through extrusion‚ fiber forming materials through holes (called spinnerets) into the air‚ forming a thread. Before synthetic fibers were developed‚ artificially manufactured fibers were made from cellulose‚ which comes from plants. These fibers are called cellulose fibers. Raw materials:

Fiber Intermediates: Fiber Intermediates have large production capacity in India. Globally the demand for all categories of Fiber is increasing at a pace of 3-4 MT annually. Polyester is accounted for 70% of the total growth of fiber in all categories in next decade. This global demand scenario has a positive impact on the Indian market as well. Polyester demand in India is likely to grow at 12% Y-o-Y to .5 MPTA. Demand of Polyester will also result into demand growth of PX which is expected to grow

HIGH TECHNOLOGY FIBRES FOR TECHNICAL TEXTILES 1 INTRODUCTION Human life is surrounded by hundreds of textile fibres either in the form of clothes‚ interior textiles or in the form of high performance technical textiles made of conventional or high technology fibres for various applications. A textile fibre is usually defined as a flexible‚ macroscopically homogenous cylindrical body mainly with circular cross- section having a high ratio of length to diameter (typically 100-3000: 1). Textile

Dietary Fiber Dietary Fiber is the parts of plant that resist digestive enzymes. A few definitions of dietary fibers are nondigestible carbohydrates and lignin that are intrinsic and intact in plants. nondigestible carbohydrates and lignin that are intact in plants. Another definition is the edible parts of plants or analogous carbohydrates that are resistant to digestion and absorption in the human small intestine‚ with complete or partial fermentation in the large intestine. Dietary Fiber are
