Raw Fiber to Yarn

Raw Fiber to the Mill

The raw fiber arrives at a spinning mill as compressed masses (bales), which goes through the processes of blending, opening and cleaning.
a)   Blending is done to obtain uniformity of fiber quality.
b)   Opening is done to loosen the hard lumps of fiber and disentangle them.
c)   Cleaning is required to remove the trash such as dirt, leaves, burrs and any remaining seeds. Our recycled cotton and polyester fiber requires no cleaning.

Blending fibers

Blended Fibers

Alternating bales of recycled polyester (rPET) (white color) and recycled cotton (pink color) where the bales will be blended and “opened” (left image) and blended bales (right image).

Carding

Carding is the initial straightening process, which puts the fiber into a parallel lengthwise alignment. Now the fiber is called ‘Lap’.


This makes the tangled mass of fiber ready to produce yarn.	The lap is treated for disentangling and molded in a round rope like mass called a "Sliver"

Drawing

'Roving' is the final product of the several drawing-out operations. It is the preparatory stage for the final insertion of twist. Until now, enough twist is given for holding the fibers together but it has no tensile strength. It can break apart easily with a slight pull.


Drawing pulls the staple lengthwise over each other. As a result, longer and thinner slivers are produced. As several stages of drawing out, the sliver is passed to the spindles where it is given its first twist and then is wound onto bobbins.	The roving, on bobbins, is placed in the spinning frame, where it passes through several sets of rollers running at high speed and finally the "Yarn" is produced at the sizes it is desired.
