Open-End Spinning

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…

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…

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…

The first functioning of rotor spinning, machine was presented at the ITMA in 1967.Yarn spinning according to the rotor spinning principle predominates for all nonconventional spinning methods.It omits the step of forming a roving.After…

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…

Carding is a mechanical process that breaks up locks and unorganized clumps of fiber and then aligns the individual fibers so that they are more or less parallel with each other. Carding can also be used to create blends of different fibers…

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.

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…
