Kapok/Capok fibre is one of the natural cellulosic fibres which grow on the kapok plant. It has a hollow body and a sealed tail, which are desirable features of candidates for functional textiles of this nature. However, the low volume weight of kapok is (specific density 0.29g/cm3), and the short length and smooth surface of the fibres, causing poor inter-fibre cohesion, have prevented kapok from being processed by modern spinning machines.
Two types of energy can be used in a specifc spinning mill; electrical energy and thermal energy. Machines, air conditioning, lamps used for illumination and compressors consume electrical energy while the thermal energy is consumed by air conditioning and processes such as fxation of yarns
In order to obtain the necessary information about energy consumption of a specifc spinning mill, one which is able to spin every kind of staple fibre (i.e. cotton, linen, polyester, viscone) in a wide count range using both ring and openend systems to be chosen.
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.
Yarns are continuous strands of fibers that can be woven or knitted into fabrics. Natural staple fibers usually requires processes such as spinning to make yarns. Silk yarn, extracted from silk cocoon are continuous filament yarns. Most of the synthetic yarns also does not require the additional processes of spinning.
Yarn spinning is the process of manufacturing yarn from different types of fibres into a continuous length from one or more type of fibers. Spinning is the most important and the initial step in fabric manufacturing. The major goals of spinning is to produce the quality yarn from raw material, then remove the process faults followed by winding the short length bobbins on Cones. There are different types of spinning, the most commonly forms of spinning are: Ring, Rotor, Air Jet, Friction etc.
The larger part of staple fibre, approx. 33 mio tons are processed in short staple spinning. This part of the spinning industry therefore is of great significance in the world of textile production.
The earliest art of hand weaving along with hand spinning remains a popular craft. There are different types of weaving looms and these include handloom, frame loom and back strap loom.
A loom is a mechanism or tool used for weaving yarn and thread into textiles. Looms vary in a wide assortment of sizes. They come in huge free standing hand looms, tiny hand-held frames, to vast automatic mechanical tools. A loom can as well pertain to an electric line construction like that of a wiring loom.
