Chapter 9 The World of Plastics and Polymers Overview • Plastics are all around us – Polymers‚ materials whose molecules consist of long chain of atoms • Natural • Synthetic • Use of material and impact on economy‚ lifestyle‚ and leisure – Word plastic to some carry connotation “cheap” or “tacky” – Synthetic polymers revolutionised modern life • eg plastics become important in automobile industry‚ some new plastics stronger than steel and resist corrosion‚ less dense than structural

Due to its reinforcing properties‚ nanocellulose can also be used in bio-composites and other matrix materials. 6.9 Concluding remarks Natural fibres‚ cellulose and other constituents of natural fibres are very promising materials for the future‚ having the capability to replace current synthetic materials. with the rapid developments in nanotechnology‚ nanocellulose brings many new insights to the materials world‚ such as its modulus value of 160 GPa‚ which is much

skin‚ textiles‚ and other solids. The seemingly simple process of cleaning a soiled surface is‚ in fact‚ complex and consists of the following physical-chemical steps: Wetting of the surface and‚ in the case of textiles‚ penetration of the fibre structure by wash liquor containing the detergent. Detergents (and other surface-active agents) increase the spreading and wetting ability of water by reducing its surface tension—that is‚ the affinity its molecules have for each other in preference

The denier per filament is 6. 0.1.2 Tyre Cord: The other materials used as tyre cord are cotton‚ rayon‚ polyester‚ fibre glass‚ steel‚aromatic polyamides. Each of these materials has its own merits and demerits. The major criteria for acceptance of any material in tyre are its tensile strength‚ dimensional stability‚ durability‚ thermal stability‚ hysteresis and adhesion

Calcaneal Tendon which adheres to the calf muscle and heel bone which allows for active range of motion (AROM) which consist of running‚ jumping and walking. The outer layer of the Achilles tendon is the paratenon layer then tertiary fibre bundle which holds the primary fibre bundle‚collagen fiber and collagen fibril. Ropes have the same structural base as the Achilles tendon‚ when you pull on one side of the rope in tug of war just like when the calf muscle contracts the Achilles tendon tightens. If

Introduction to Spinning : The annual world fiber consumption in 2004 amounted to approx. 70 mio tons (synthetics: 38 mio tons‚ cotton: 22 mio tons‚ cellulose fiber: 2.5 mio tons and others: 7.5 mio tons).While about one third of the man-made fibers is processed as endless filament‚ still two thirds come in staple fiber form. The larger part of staple fiber
