TEXTILE PROCESS


In this section we want to sum up in a easy way the steps needed to transform raw fibers into yarn according to the semi-worsted process.
To make understanding easier some optional processing have been purposely disregardeded (e.g. dehairing, dyeing, steaming) The images have only an illustrative purpose and show different materials in the various stages of the manufacturing process.

We start from the raw fibers after shearing:


SKIRTING - TUMBLING

This process removes the larger impurities and reduces the dust content

SCOURING

Scouring removes grease, dust and dirt

OPENING

Using the picker fibers are opened so as to obtain small tufts

CARDING

During the carding fibers are aligned and regularised to get an even web or sliver

PIN DRAFTING (GILLING)

By means of the pin drafter errors into the sliver are reduced and the fibers are aligned by the combs

SPINNING

The spinning frame turns the sliver into yarn.
Machinery parameters determine the characteristics of the yarn

PLYING

Plying is a process used to create a strong, balanced yarn.
It is done by taking two or more strands of yarn and putting them together.

WINDING

Winding can be defined as transferring yarn from ring tube into a convenient form of package (cone, ball, skein)
