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.

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

Water

↓

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
