The Machine Drive
About 20% of production costs in a spinning mill fall under the heading “energy”, and of these costs about two thirds are incurred in the ring spinning section. For example,…
Introduction to Ring Spinning Frame
The ring spinning machine was invented in the year 1828 by the American Thorp. In 1830, another American, Jenk, contributed the traveller rotating on the ring. In more than 150…
What parameters influence the combing performance
Properties of cotton : Fiber length and its uniformity: These parameters play critical role in deciding the combing performance. If the fibre has high short fibre content, then the improvement…
Introduction to combing
Combing process removes predetermined level of short fibres from the group of cotton fibres. It is well known that the cotton fibres have distribution of fibre lengths starting from long…
Spinning Process of Filament Yarns
A filament fiber is the fiber which comes in continuous lengths for use. All the man-made fibres and silk is filament in nature. The man-made fibers can also be cut…
Sequence of Operation
The feed stock in form of either card sliver or draw frame sliver from first or second passage drawing. The sliver runs from a can beneath the spinning unit into…
Principle of Rotor Spinning
The Rotor: The rotor is the main spinning element of the rotor-spinning m/c. Yarn quality ,character working performance of yarn productivity, & costs etc. all depend chiefly on the rotor.…
Auxiliary Function of Winding
Creeling: Creeling is the placement of full packages in position ready to be unwound as part of the transfer operations. An alternative meaning is the removal of the exhausted packages…
Warping Creels
Creel: Independently of the warping system, the threads are fed from bobbins placed on creels. The creels are simply metallic frames on which the feeding bobbins are fitted; they are…
Modern Spinning Methods and Developments
Although ring spinning has the advantage over earlier systems of higher production speeds and consequently reduced labour costs, the largest size of yarn package that could be built was limited…
