Simplex Frame and its Parts
The chief function of the simplex frame is the attenuation of sliver. Insertion of protective twist in order to hold the fine strand of silver. Winding of roving into a package that can be transported, sorted, donned on ring spinning…

Cone Winding in Ring Spinning systems
The cop which is prepared in the ring frame is not suitable for further processing. So the yarn is converted into the shape of a cone which is prepared in the winding. Practical experience shows that winding process alters the yarn…

Roving Frames in Ring Spinning Systems
The input of roving frame is silver that comes from draw frame section where only parallel of comber sliver. The roving section reduces the linear density of draw frame silver by drafting. After reducing the linear density the silver is…

Yarn formation using Air-Jet Spinners
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…

Yarn Doubling – types, objectives, and application
Doubling reduces unevenness of single yarns and the strength of the doubled yarn is correspondingly better than the single yarns. In this article Ring Doubling, Two-For-One (TFO) twister, quality required by yarn to get best-doubled yarn…
