Synthetic fibers are made from synthesized polymers or small molecules. The compounds that are used to make these fibers come from raw materials such as petroleum based chemicals or petrochemicals. These materials are polymerized into a long‚ linear chemical that bond two adjacent carbon atoms. Differing chemical compounds will be used to produce different types of fibers. Although there are several different synthetic fibers‚ they generally have the same common properties. Generally‚ they are known

the industry matured‚ Asian Agri had expanded its plantations and developed palm oil trading‚ refining‚ and exporting capabilities. By 2010‚ Asian Agri was an established grower and Indonesia’s third-largest palm oil exporter. Known as the "golden crop" in Southeast Asia‚ palm oil had the highest yield‚ lowest production cost‚ and largest annual production level of any edible oil‚ making it an abundant and inexpensive food source to the many fast-growing populations across Asia. In commercial food

plants seed‚ nut or flower will begin to form. Nearly one third of crops around the world are pollinated by bees‚ crops such as kiwi‚ almonds‚ cherries‚ grapes‚ tomatoes‚ blueberries‚ alfalfa etc. In the past 50 some years‚ the population of honey bees has decreased to about half. Without these little critters‚ we will lose the majority of our produce crops‚ the lack of supply would dramatically increase prices. The lack of clover‚ a crop bees rely on as an important source to produce nectar‚ would mean

The strength of a fiber is directly related to chain length. Hydrogen bonding occurs between cellulose chains in a cotton fiber. Hydrogen bonding occurs when hydroxyl groups within the chain are polar‚ meaning the electrons surrounding the atoms are not evenly distributed. As a consequence‚ hydrogen atoms of

Ancient Chinese Now allow me explain these marvels. Row planting was first planted in 6th century BC. This way of planting allows the crops to grow faster and stronger and they also realized that as the wind travels there is less damage in crops planted in rows due to the wind passing through gently. It is also more efficient in watering‚ weeding and harvesting the crops. The compass was created in 4th century BC and was made of lodestone. The compass was first used by fortune-tellers before it was

Pre-Production: • Harvesting of corn requires fossil fuels to run tractors and other machines • Fossil fuels required to ship to factories. Production: “First‚ the harvested corn crop is soaked and ground so that the endosperm can be separated from the gluten and fiber. This step is typical in grain crop harvesting‚ too. Next‚ producers add enzymes to the starchy endosperm‚ which converts the endosperm into a simple sugar called dextrose. Then‚ the addition of bacterial cultures causes the

Agriculture‚ also called farming or husbandry‚ is the cultivation of animals‚ plants‚ fungi‚ and other life forms for food‚ fiber‚ biofuel‚drugs and other products used to sustain and enhance human life.[1] Agriculture was the key development in the rise of sedentary human civilization‚ whereby farming of domesticated species created food surpluses that nurtured the development of civilization. The study of agriculture is known as agricultural science. The history of agriculture dates back thousands
