and the durability and wrinkle resistance of polyester. Rayon is a “Man-Made Fiber”. Rayon is highly absorbent‚ soft‚ comfortable and drapable. Some Rayons wrinkle easily and become weak when wet. Trademark uses of Rayon are blouses‚ dresses‚ coats‚ suits‚ and lingerie. It is found in a range of woven and non-woven apparel and is also in home furnishing fabrics. To care for this fiber‚ follow care label instructions precisely. Some Rayons may need to be dry cleaned and some are

INTRODUCTION a) Background of the Study Ever since man utilized various species of plants for food‚ clothing‚ as medicines‚ fibers and other useful things. In fact‚ the interaction of man and the plants led to the establishment of the so-called traditional knowledge. One should look into the potential impact of the plant which are generally rich sources of many natural products‚ and its ecological environment and the manner on how it could be utilized for significant use for human welfare

REFERENCES 9 1. INTRODUCTION: Nanofiber technology is a part of nanotechnology. The major purpose of this technology is to create nanoscale fiber materials which can achieve superior functions. The nanofibers have such good features as flexibility‚ high specific surface area and should have a good directional strength. For these features‚ the nanofibers are used in a lot of applications that
