Sizing

Sizing are two type
1.warp sizing
2.fabric sizing

warp sizing:

 Objectives

To improve the weavability of the warp yarns and to over come inherent deficiencies of the yarns

To hold the individual fiber of yarns together so it withstand stress and strain

 

 

Sizing is a process:

Of applying a film forming polymer to the warp yarn  

To provide temporary protection to the warp yarns from abrasive and other types of stresses generated on the weaving machines 

To reduce warp breakages

Agent &process 

The agent of this process is commonly starch and other additives such as sizing greases, waxes, paraffins, antistatic agents, etc, but they have defied problems at the desizing process

The sizing process lasted different time (3,5 and 10 min) bath ratio 1 : 20 and solution temperature 20 and 60°C

 

 

Sizing Machine 

 

 

What sizing should do?

 it should:

•Improve  tensile strength and abrasion resistance of the yarn

• Reduce the hairiness of the yarns

• Reduce the generation of static charge when polyester- blend-     yarns is used

• Improve over all efficiency of the weaving process

 

 

 

Sizing method:

 

•Hank sizing method

•Single ends sizing method

•Slasher sizing method

Resin finish

objective:

After dyeing, finishing process is usually given to improve  their quality and value

There are processing to improve handles (like stiff,    bulky,crush resistance, softening sinishing), anti static, water and oil repellent, permanen press and soil release finishing, etc
