Water Vapor Permeability
B120 sample showed better result 824.0 g/m
2 /day. In general, there was increase
in permeability from 9 to 13 oz samples due to increase of cotton content in the
fabric. 13 oz indigo dyed denim resulted in better permeability. But ideal fabric for
PC would be 11 and 9 oz, while 13 oz absorbs more water/moisture, and moisture
takes time to evaporate, thus making the denim heavier.
Tensile Strength and Percent Elongation
Indigo dyed 13 oz denim due to higher fabric weight and twill structure had the most
suitable tensile strength. 9 and 11 oz gave good average results. Increase in fabric
weight resulted in increased compactness of the twill weave construction, hence
resulting in better strength to various tension.
Water Absorbency
Water absorbency is the ability of denim to absorb water within its structure. 9 oz
denim showed the maximum absorbency by 2 s and 11 oz showed absorbency by
3 s. This is due to capillary action and less surface area in 9 oz and 11 oz denim
as compared to 13 oz denim. Hence, 9 and 11 oz denim were suitable for upper
garments (shirt, jacket) in protective clothing as they easily absorb the water moisture
and evaporates from body.
Tear Strength
The maximum tear strength was found in 13 oz indigo dyed denim, when value was
80.53 N in control sample and increase by 1 to 2 N. On the other hand, 9 and 11 oz
gave average values. Hence 13 oz denim was ideal for lower garments in protective
clothing and can be used in high tension, to resist the possibility of tear along the
breach or damaged position.
Abrasion Test
The ability of fabric to resist surface wear caused by flat rubbing in contact with
another material was observed as above average in all the three weights of indigo
dyed denim.
Durability to Laundry
Results showed an increase in water absorption and permeability after laundry while
the effect of anti-microbial properties did not wear out much in indigo dyed fabric.
Hence, the fabric results in better linkage with finishes. Both the finishes after wash
cycles gave similar results, that is the flame-retardancy was found to be good and
stain release gave grade 4 out of 5 even after 10 wash cycles.
