as a viable alternative to glass fiber reinforced composites especially in automotive and building product applications. The combination of biofibers such as kenaf‚ hemp‚ flax‚ jute‚ henequen‚ pineapple leaf fiber‚ and sisal with polymer matrices from both nonrenewable and renewable resources to produce composite materials that are competitive with synthetic composites requires special attention‚ i.e.‚ biofiber–matrix interface and novel processing. Natural fiber–reinforced polypropylene composites

milk fabric is new born fabric. The milk protein fabric moistens skin and it is healthy and bacteriostatic - it is the perfect material to produce underwear and socks‚ pants‚ long-sleeve T’s and jackets also. The important ingredients of milk protein fiber are milk casein proteins‚ which can nourish and lubricate the skin. The milk protein contains the natural humectant factor‚ which can capture the moisture and maintain skin’s moisture to make the skin tender and smooth and reduce wrinkles. Its cost

homicides were proved to be linked to the same killer. Police did not have a huge amount of forensic evidence to track down the killer. They only had the evidence of fibers from the bodies and clothing of the victims. The fibers were unusual ones. Some of the fibers were yellow-green nylon and some had a cross section shape to them. The fibers apparently were used in rugs or carpets. In February 1981‚ the killer began dumping bodies into the Chattahoochee River. The victims found were completely or

there exist parallel universes‚ exactly like our universe. (2)These universes are all related to ours; indeed‚ they branch off from ours‚ and our universe is branched off of others. Within these parallel universes‚ our wars have had different outcomes than the ones we know. Species that are extinct in our universe have evolved and adapted in others. In other universes‚ we humans may have become extinct. (3)For many years‚ science fiction writers have linked the notion of a parallel universe to hyperspace

disadvantages of natural and synthetic fibers a. Natural fibers: i. Pros: They don’t deteriorate or melt as quickly and as easily as synthetic fibers do. ii. Cons: They aren’t very strong. b. Synthetic Fibers: i. Pros: They are very strong. Way stronger than the strongest fiber ii. Cons: They deteriorate in super bright sunlight‚ and melt at a lower temperature than natural fibers. 12. What is the difference between fibers‚ textiles‚ and fabrics? a. Fibers: the smallest indivisible unit of a

fluid determines the efficiency of the napkin. This bulk layer of a napkin is a non woven web‚ made of hydrophilic cellulosic staple fibers like wood pulp‚ cotton linters‚ viscose etc (IS: 5405 – 1981). Most of the wood pulp used for the purpose is imported‚ and therefore expensive‚ increasing the overall cost of a sanitary napkin. Cotton is seen as a major fiber poised to replace wood pulp especially in the feminine hygiene products where ‘less bulky’ is preferred and ‘thinner is better’. The
