Yarn Manufacturing // Blow room, Carding, Draw Frame, Simplex, Ring Frame

An assemblage of fibers that are twisted or laid together so as to form a continuous strand that can be made into a textile fabric. So a yarn is a strand of natural or man-made fibers or filaments that have been twisted or grouped together for use in weaving, knitting, or other methods of constructing textile fabrics. The type of yarn to be manufactured will depend on the fibers selected; the texture, or hand, of the fabric to be made; and qualities such as warmth, resiliency, softness, and durability required in the fabric's end use.

01. Section: Mixing of raw cotton.

Input:
Bale of raw cotton.

Object:

1. To mix different staple fibers properly.
2. To minimize cost.
3. To produce a better quality of yarn at the last stage(ring).
Output:
Mixed raw cotton.

02. Section: Blow room

Input:
Mixed raw cotton.

Object:

1. To open the fibers.
2. To remove the trash.
3. To mix the fibers.
4. To make uniform lap sheet.
Output:
Lap.

03. Section: Carding.

Input:
Lap.

Object:

1. To remove fine trash.
2. To remove short fibers, neps, motes, and foreign materials too.
3. To produce regular sliver.
Output:
Carded Sliver.

04. Section: Draw frame

Input:
Sliver.

Object:

1. To parallel the fibers.
2. To blend and mix the fibers.
3. To reduce weight per unit length.
4. To make uniform sliver.
Output:
Regular sliver.

05. Section: Simplex.

Input:
Drawn sliver.

Object:

1. Draft the material.
2. Insert a small amount of twist.
3. To make bobbin with roving of conical shape.
Output:
Roving.

06. Section: Ring Frame.

Input:
Roving.

Object:

1. Drafting (attenuation).
2. Insertion of twist to strengthen the yarn.
3. To wind the yarn on to the ring tube/bobbin.
Output:
Yarn.
