Sizing Machine

Sizing machine is a weaving machine in textile mills and this machine is used by textile manufacturers to apply size material to the warp yarns before weaving. This machine is not necessary for knitting which used for textile sizing . It is used to protect the yarn from abrasion and improve the breaking strength of the yarn of textile world.

Process definition

Sizing is a process by which films of chemicals are applied over the yarn.

  • To impart more strength in the yarn.
  • To impart more resistant to abrasion.
  • To impart flexibility in the yarn.
  • To reduce hairiness in the yarn.

Process requirement

  1. Direct warp beam sizing machine.
  2. Sectional warp beam sizing machine.

Factor on which recipe depends

  1. Composition of yarn
  2. Yarn count
  3. Total no. of ends
  4. Weight of yarn

Size beam width

X=Total Ends/Ends /inch

If the value of X is more than 60, then the size beam width is 72-74.

If the value of X is lower than 60, then the size beam width is 67.

Practical Yarn Recipe

Size cooking procedure


PVA (10 minute steamed 700c)

Starch (30 minute steamed 900c)

Size + Wax

Steam (20 minute at 900c)

Cooked size

Determination of size% by Refractometer

Take the meter

Cooked size collect

Give on the tip of the matter

Observed the scale inside

Rating find in the scale

Determination of viscosity by viscosity cup

Take the viscosity cup

Collect the cooked size in the cup

Determination the time required to drop out the liquor from the bottom hole of the cup

If 22-30 second required then the viscosity is OK

Maintenance of sizing machinery

Problem 1: Creel housing vibration.

Solve – Change the key of creel housing.

Problem 2: Pressure does not adjust properly.

Result: Uneven sizing.

Cause: Worn out pressure roller.

Remedies: Grinding the roller/ Change the roller.

Problem 3: Winding tension does not correct

Result: Hard/loose warp beam.

Cause: PVI box does not work correctly.

Remedies: Maintenance of PVI box of Sizing Machine
