Reactive dyes

Hi im back .... with the reactive dye .

When there is a matter of dyeing we should first choose a term reactive dye . a very important name related to dyeing

Spinning Geometry

Hey .............
Now im going to write about it .....

From Roving bobbin to cop, the fibre strand passes through drafting arrangement, thread guide, balloon control rings and traveller. These parts are arranged at various angles and distances relative to each other. The distances and angles together are referred to as the spinning geometry,has a significant influence on the spinning opeartion and the resulting yarn. They are .......

Ring Frame 03

RING and TRAVELLER COMBINATION

  The following factors should be considered  o materials of the ring traveller 
o Surface charecteristics 
o The forms of both elements 
o Wear resistance 
o Smoothness of running 
o Running-in conditions 
o Fibre lubrication

For the rings two dimensions are of primariy importance.
1.internal diameter
2. flange width.
