                                     What is the sizing?

 Sizing is a process in which adhesive paste is prepared by mixing with water and applied to the yarn.

The object of sizing:-

• To Improve the wave ability of for yarn by making it more resistant to the action of using like friction tension etc.
• To maintain good fabric quality by reducing heron's weakness in yarn.
• The tensile strength of yarn is increased by sizing.
• The elasticity of the yarn is also increased.
• Wedding size material and weight are increased.
• To increase the yarn friction resistance.

Sizing ingredients used in the sizing process:-

• Adhesive
• Lubricants or Softener
• Antiseptic or Anti-Mildew Agent
• Wetting Agent
• Anti Foaming Agent
• Tinting Agent
• Weighting Agent

The technique is used for sizing:-

There are three-technique followed in sizing depending upon the quality of warp required for weaving.

1. Hank sizing
2. Slasher or Tape sizing
3. Bail warp sizing

1. Hank sizing:-

• Small manufacturers in remote rural places are generally used hank size process.
• After sizing the size hanks are shaken, stretch and brushed in order to achieve through and uniform distribution of size.
• This process gives very low production.

2. Slasher sizing:-

• It is the process of assembling desire number of warp threads in a continuous sheet.
• In this Sizing drying and beaming is in the stage.
• This method is one universal method followed for large production.

3. Ball -Warp sizing:-

• In this method, the warp in the form of loose rope is immersed through the size paste.
• Sizing, drying, beaming are separately done in three stages so there is a scope for penetration of size into the yarn.
• Since the winding is done separately after some time of drying, the yarn has enough time to absorb moisture from the atmosphere. This gives the mellow feel to the yarn.
• Also, there is a little tension on yarn during sizing and drying, which prevent the extensibility of yarn
