Manufacturing
Manufacturing is the use of tools, machines and labor to produce goods for sale or use. It may refer to various human activities ranging from handicraft to high tech, but is most commonly applied to industrial production where raw materials are transformed into finished goods.

What are the coolest jobs right now?
it real depends on what type of person you are.
In my personal veiw a games tester would be pretty fun, sure it has it down sides having to be able to spot out glitches and other faults, but would be fun testing out the latest block buster!
What is difference between lean production and mass production?
The difference between the two is that batch productions is a form of production that is applied to a large number of items all at once whilst mass production is the same but made one at a time from mass produced parts.
Can you use rubber bands to castrate dogs?
Regular rubber bands typically cannot, but there are special rubber bands that are used to do that sort of thing. They are placed on the tail and left on the tail until it eventually falls off.
The fibres are triangular prism like structure. so the silk cloth refracts the light falling on it at different angles and gives a shimmering appearance.
How is a cotton plant turned in to threads?
A very simple list of the steps:
- Picking (the bolls from the plant)
- Ginning (removing seeds)
- Spinning (the fibers into thread or yarn)
- Weaving (the yarn into fabric)
How many frost-free days does cotton need to grow?
200. learned about it the other day in my history through 1877 class i'm taking right now at my university
How is silk obtained from a cocoon?
The mulberry silkworm caterpillar spins about one mile of thread for its cocoon. The farmers who specialize in this production arrange special frames for the caterpillars, and the caterpillars are killed with heat when they have finished building their cocoon. This is then immersed in hot water to soften the adhesive part, and wound up on spools. Several threads are wound together to make a usable fibre.
The thread from the Bombyx mori (silkworm) is triangular in section, and is about 5 - 10 microns wide.
The earliest silk fabric dates from about 3500 BCE, and the silk trade had spread such that an Egyptian mummy of about 1070 BCE had some silk in the hair.
Spider silk is about one-third the diameter of silk from the mulberry moth.
How do organic methods differ from traditional farming methods?
Organic farms follow a strict set of rules dealing with what they can and cannot use in regard to fertilizers, pesticides, etc.

The manufacture of rubber begins with the rubber tree, botanical name hevea brasiliensis. Originally from Brazil, specimens were moved to Malaya (now part of Malaysia) and Burma (now Myanmar) where large plantations were established in the nineteenth century. The tree is tapped by making a shallow v-shaped slit in the bark; a spout is inserted at the bottom of the V and the sap of the tree is collected.This sap, called latex, may be shipped out after cleaning for making certain types of rubber products. Most latex is poured into large flat trays to be dried over a wood fire on the plantation. The resulting solid sheets are then passed through a mill fitted with ribbed rollers, which form corrugations on the sheets about a centimeter apart. The result of this is a product known in the rubber trade as ribbed smoked sheets (always abbreviated to RSS). RSS is then pressed into bales of around 100Kg; it is the same colour as a smoked herring (aka kipper) and smells like one too. The bales are shipped all over the world for processing. The next step in making a finished rubber product is to masticate the RSS. This is done on a calender mill, where the raw rubber is fed between two rollers that are slightly separated from each other and turn at slightly different speeds. Various other ingredients are then fed in. These usually include a filler (which is mostly either soot or china clay), one or more lubricants and, finally, a vulcanising agent. This last is usually powdered Sulphur, although some usable organic compounds are known. When all ingredients are well mixed uncured components are formed, either in moulds or by extrusion. They are then heated; this heating carries out the process of vulcanisation, in which the sulphur causes the formation of cross-links between rubber molecules. These links greatly improve the mechanical properties of the final rubber product over a range of temperatures, especially preventing the rubber from being brittle when cold or sticky when warm.
Natural rubber comes from the bark of the Hevea Brasiliensis tree that grows in Southeast Asia. To harvest this rubber, someone makes a small cut in the bark of the tree and a the milky white substance, latex, flows out of it. It is then mixed with water and acid to make the substance thicker. Also, different companies mix different chemicals into the latex to add color and to make the rubber stronger and stabilized.
Caterpillars << please note the spelling, it will help you find more information!
They make silk to spin a cocoon. The caterpillar eats a lot of mulberry leaves and its body transforms the leaves into whatever nutrition it uses to make silk. (Kind of like a spider makes thread inside itself.)
The caterpillar makes a cocoon around itself to protect itself while it becomes a butterfly.
But, the ancient Asian people somehow figured out that you could take these cocoons and cook them, which loosens the silk so that a person can "unwind" the cocoon -- basically, a person can un-spin the cocoon that the caterpillar was spinning.
Of course the caterpillar dies from this.
You can also look up "silkworm" on Wikipedia.
Hope that helps! HC
What is rubber tree sap called?
When liquid exudes from a tree it is called sap.
When it hardens it is called resin.
When ancient tree resin becomes fossilized it is called amber.
Which trees give us most of the wood pulp from which paper is made?
Trees make paper when they are cut down and processed into sheets. This process involves bleaching the wooden sheets white.
How do you plant a rubber tree?
You cannot divide a rubber plant normally, you should air layer it if you want to propogate it.
What products or things that comes from animals?
The most obvious product of animals is meat. The next product would be hides and wool, but there are some others. Animal collagen is one of the most important products from animals. Collagen is used in the manufacture of cosmetics, and many pharmaceutical products. Even everyone's favorite, Jello! is made from the collagen of animals.
What are the largest fur manufacturers?
The four largest fur manufacturers and retailers were all located in New York: Mohl Fur Company, Inc.; Marc Kaufman; Associated Fur Manufacturers Co.; and J. Mendel Fourrure.
How is the harvester ant harmful?
Harvester ants can sting and some sensitive individuals may be harmed. Otherwise, they are not harmful.
Besides ferocious bites and venonmous stings--which can be quite dangerous to allergic people--in the northern United States, the carpenter ant is another common intruder in and around buildings and dwellings constructed mostly of wood, e.g., cabins, barns, outhouses and corrals. They love wood and can cause damage similar to damage caused by termites. Trees are another favorite of the carpenter ant. Colonies of this structural bugger usually gnaw out the galleries and chambers of their nests in wood initially infested by beetles. Most beetle damage is done to pine trees.
On the other hand, carpenter ants may actually contribute to forest economy by hastening the breakdown and recycling of timber previously infested by other insects, usually beetles. It's simply natures way of eliminating old-growth trees, creating room for new-growth trees
Animal fats are lipid materials, both oils and fats. Fats and oils are both made up of triglycerides. Oils are liquid at room temperature and fats are solid.
How do rubber trees turn into natural rubber?
They collect latex from the rubber tree by tapping it and let it drip into a bucket and wait till it stops. It is then processed and various chemicals added, predominately sulphur to allow it to be hard and still flexible at the same time.
What is the name of fine strong silk?
Darwin's bark spider (Caerostris darwini) has the toughest silk ever seen - more than twice as tough as any previously described silk, and more than 10 times stronger than Kevlar.
Name the machine that harvests cotton?
Cotton is harvested using two methods in North America.
The first is the cotton stripper:

How long does it take for a wool mitten to decompose?
It could take about 3 months for the first compost to decompose. to get it to decompose faster try to grind or shred it.
Please see my comments; but excuse my spelling toward the end, since there are no 'nub tree leaves.' There are however 'Nut Tree Leaves.' Enjoy your dirty finger nails.
