Energy consumption for different type of yarns
Energy consumption is different on various yarn types, for example, energy consumption for combed yarn is higher because of the additional production step – combing.

Weaving is the process of making cloth with two components, a warp, and a weft, and can be done by very simple techniques on a complicated loom.
Fabrics can be constructed in a variety of ways, ranging from the matting together of fibrous materials to the intricate interlacing of complex yarn systems.
Polyester fibers, the synthetic fibers, are long-chain polymers derived from coal, air, water, and petroleum. They are formed through a chemical reaction between an acid and alcohol. Polyester is often blended with other fibers like cotton to get the best of both worlds.
Silkworms, which are really caterpillars, are fed mulberry leaves, mulberry leaves, and only mulberry leaves. They never stop eating. That means feedings every four hours.
Diagonal weave are basically type of twill weaves confined to bold twills running at angles greater than 45°, although often regular 45° twills are spoken of as diagonals; regular diagonals are generally formed by combining two regular 45° twills in their picks or ends.Diamond weaves are type of twill weave which forms the shape of a perfect diamond.
Derivatives Formed by Rearranging Ends or Picks- The number of what may be termed fundamental weaves is comparatively small, but the weaves that may be derived from them are innumerable. Thus, if a simple twill weave is shown out in design paper, several other weaves may be obtained from it by rearranging either the ends or the picks. Designs thus obtained are termed derivatives.
The angle of twill weave is determined by the amount of shift in the points of interlacing.A one pick one end shift twill weaves called 45-degree will.A twill weave which has more than one pick shift and one end shift is called steep twill; if the shift is more than one end and one pick it is called reclining twill.
Although most orders for garments are placed by buyers on FOB basis, with buyers to pay for freight at the shipping destination, it is still necessary for the shipper or the agent to know how to calculate sea freight and air freight as buyers always need to know how much freight the merchandise cost per dozen. If you are required to sell on CIF basis, (with the shipper to prepay for freight at the shipping port) you will need to calculate the freight accurately for your own costing
The emphasis on productivity and quality has developed the weaving technology very much and as a result the working hours required to weave fabric from loom have been reduced from about 20 to 0.25 during the last 125 years, and in the last 50 years there has been a reduction of 95% inoperative hours per standard unit produced.
