The results of energy consumption calculation in spinning mills on machines and compressed air.
In order to obtain the specifc energy consumption of any yarn, each an every machine in the spinning operations right from the bale opener and the approach should be repeated for the rest of the machine/step.
In order to obtain the necessary information about energy consumption of a specific spinning mill, one which is able to spin every kind of staple fiber (i.e. cotton, linen, polyester, viscose) in a wide count range using both ring and open-end systems to be chosen.
The cost of yarn consists of several factors such as raw material energy or power, labor, capital etc. The cost of yarn excluding raw material is termed manufacturing cost. The share of the factors in manufacturing cost changes according to the yarn properties, machine operational properties and economical situation of the spinning mill.
The Air-Jet spinning is very sensitive to the fiber length and fiber length distribution(short fiber content) of the material being processed. The amount of wrapping twist varies depending upon the length of the wrapping fibers as only a part of the total extent is utilized to wrap the core fibers. Wrapping the fibers shorter 12.5 mm practically do not make a significant contribution to the strength of the yarn.Air-jet Spinning is suitable for processing medium and long staple comber cotton fibers a
Yarn making from staple fibers involves picking (opening, sorting, cleaning, blending), carding and combing (separating and aligning), drawing (re-blending), drafting (drawing into a long strand) and spinning (further drawing and twisting). Silk and synthetic filaments are produced by a less extensive procedure. Current high-production yarn-making operations are performed on integrated machines that perform this entire sequence as one combined operation.
The new spinning systems clearly avoid the limitations produced by the twist insertion mechanism. It is possible to increase the twist insertion rate and the yarn production speed quite considerable. Various spinning techniques specifications.

Air jet spinning has offered yarn manufacturers the opportunity to produce yarn at relatively high production rate. Unlike other spinning methods in which productivity is limited by the amount of twist in the yarn, Air Jet yarns can be produced at the same production rate regardless of yarn counts. Murata Vortex Spinners are one such leading Air Jet spinning machines which excel at producing finer yarns (Ne 40/1-60/1), because of the improved strength imparted to the smaller fibre bundle.
Blow room is the starting of the spinning operation where the fiber is opened, cleaned, mixed, micro dust removed and evened thus passed to carding machine without increasing fiber rupture, fiber neps, broken seed particles and without removing more good fibers. The basic functions of blow room are opening, cleaning, dust removal, blending and evenly feeding the material on the card.
