Briefly Description of Sizing Ingredients ?

Size Ingredients and their function:

Starch or Adhesive:

The carbohydrate component extracted from certain plates is called starch.
Example: Starch not maize, corn, potato etc.

Function:

· To improve the strength

· To increase smoothness

· To increase elasticity

· To increase stiffness

· To impart adhesion

  

Softening Agents: 

The agent which is used to give fabrics a soft handle and frequently smooth appearance is called softening or lubricating agent.
Example: Japan wax, tallow, lin seed oil, coconut oil, animal fats, mineral oil, T.R.O., soap etc.

Function:

· To make the yarn soft and slippery

· To smoothen the yarn

· To reduce the stiffness

· To reduce flexibility and friction

Antiseptic or Anti mildew Agent:

 The substances which prevent the mildew formation is called anti-mildew agent.
Example: Carboxylic acid, sali cylic acid, Zinc chloride, phenol etc.

Function:

· To prevent mildew formation

· To prevent size material for a longtime

· To help to store the size yarn

· To protect yarn from bacteria or fungi.

Hygroscopic Agents:

 The agents who are used to moisture yarn and to prevent excessive drying of yarn is called hygroscopic agent.
Example: MgCl2, CaCl2, Glycerin etc.

Function:

• To moisture the yarn
•  To prevent excessive prevent of yarn

Weighting Agents: 

The agent which is used to increase weight of yarn and to impart the fullness and feel to the fabric is called weighting agents.
 Example: China clay, Sodium Sulphate, French chalk etc.

Functions:

· To increase the weight of yarn during finishing

· To impart fullness and to fell the fabric

· To prevent opening of the cloth.

Tinting Agents: 

The agent which is used for the temporary coloration of textile materials is called tinting agents.

Example: Blue, Tinapol, Optical brightener etc.

Function:

· To increase the brightness and to remove the yellowish color ofyarn

· To prevent dusting off

· To form a particular shade

Wetting Agents: 

The agents which are used for uniform distribution of the sizing solution is called wetting agent.

Example: Sulphanol, soap, MgCl2 etc.

Function:

· To increase size exhaust

· To obtain a distribution of the sizing solution

Antifoaming Agents:

The substrates which prevent the foam formation is called antifoaming agent.

 Example: Pyridine, Benzeneetc.

Function:

· To prevent foam formation

· To give uniform size pickup

NeutralizingAgents:

This type of agent is used to neutralize the sizing solution.
