Comfort properties of yarn

 Yarn count, spinning technique, pore size in yarn, blend ratio etc. properties of yarn influences thermal insulation, vapor permeability, air permeability, bending rigidity, evenness, frictional property, strength etc.

  Increase in yarn coarseness result in increase in fabric thickness & fabric thermal resistance. 

 Increase in yarn fineness result in decrease in fabric thickness, thermal resistance, thermal conductivity but water vapor permeability increases. 

 Fabric produced from highly twisted yarn shows lower wickability. 

 Thermal property of fabric is highly dependent on yarn structure, fibre x-section & fibre content in the blend. 

 Fabric with air-jet yarn shows higher air permeability, vapor permeability, higher absorbency & thermal insulation over ring spun yarn.15

  Fabrics made from compact yarn are more brilliant, glossy, smooth handle & better pilling behavior.  The bulky structure of textured yarn causes a more porous construction, hence good thermal insulation, soft & spongy feeling. 

 Fabrics produced from textured yarn are warmer.
