Effect of yarn cou
Effect of fabric structure
a - The regular hopsack 2/2 have obtained the highest rates of air permeability , followed by twill 1/3 and then satin weave .
b - The regular hopsack 2/2 have recorded the highest of water permeability.
c- The regular hopsack 2/2 have achieved the highest rates of thickness , followed by twill 1/3 and then satin weave.
Effect of yarn count
a-The more denier the yarns get , the lower air permeability the samples become.
b-The more denier the yarns get ,the lower water permeability the samples become .
c-The more denier the yarns get , the higher thickness the samples become
d-The more denier the yarns get , the higher weight the samples become
Effect of yarn type
a-Samples produced of polyester have recorded the highest rates of water permeability and air permeability ,whereas samples produced of lycra yarns has recorded the lowest rates . b- Samples produced of lycra have recorded the highest rates of thickness and weight ,whereas Samples produced of polyester have recorded the highest rates , but difference had an insignificant .
