In this study, air permeability of single jersey was investigated with variable stretching conditions in wales
direction namely 10%, 20%, 30% and 40%. Types of yarn used for the study included ring spun yarn, rotor yarn and core
and cover spun yarn with the count of 40 Ne. The loop length of the knit were kept at 0.35 cm, 0.40cm and 0.45 cm. Three
types of relaxation treatment have been given to the fabrics namely dry relaxed, wet relaxed and fully relaxed treatments.
Based on the experiments, it is observed that irrespective of loop length and fabric relaxation treatment ,all the knitted
single jersey fabrics except core spun structure showed gradual reduction in the air permeability value as function of
increase in the stretch. In the case of core spun (Cotton/Spandex) structure, the inverse behavior on air permeability was
found which is attributed to its high elasticity as compared to other types of yarns.It is further understood that the
progressive stretch% on single jersey knitted fabric has strong impact on air permeability in respect of all the samples
tested. The fabric samples produced from the yarns of three different spinning systems i.e; ring yarn, rotor yarn and core
&cover yarn differ in its air permeability value .The loop length and types of relaxation treatment also influences the air
permeability of the single jersey knitted fabrics. It is further understood that the interaction affects the said parameters
which have bearing on the air permeability to a large extend. Among all samples, knitted fabric made out of core spun
system exhibit comparatively the lowest permeability.
