3-1 Pilling property:
3-1-1 Blend composition and yarn count:
From table (2) it is observed that pilling tendency of the
fabric samples increase with decrease in the wool content of the blend in the
all samples. This may be due to the fact that greater number of polyester
fibers migrated on the surface of yarn with increase in the polyester content
of the blend and hence the pilling increased, and converse is true for wool
fibers used in the blend. Wool fibers fuzz more readily than polyester fibers
but this fuzz wears off easily.

F-test = Calculated F value, the
significant influences are marked by bold
(Significance level: P< 0.05)
It is also evident from table (3) that yarn cont has
significant affected on oiling tendency of the fabric samples, the yarn count
becomes finer pilling decreasing, which may be due to the fact that fine yarns
are used to weave fabrics, the number of intersections is greater than when coarse
yarn is used. In the other hand coarse yarn is less compact and results in more
slippage of fibers as compared to fine yarn, this result is not agreement with
the findings of Richards and Sharma.
3-1-2 Weave Structure and fabric set: -
It is seen from results shown in table (2) that satin woven
fabrics have lower pilling resistance as compared to twill and plain woven
fabrics. In other words, the longer the float length the higher is the pilling
propensity. In case of plain woven fabrics, there is higher number of
intersections between the warp and weft yarns which offers an increase to
slippage of fibers and difficult to easily fuzz formation on fabric samples
surface.
It is also seen from table (2) that weave structures and
fabric specifications have great influence on the fabric cover factors. In case
the fabric cover increases, this yields to decrease the pill tendency of fabric
samples due to increase number of cross- over points (intersections between the
warp and weft yarns).
It is also observed from tables 3 and 4 that weave
structures and fabric sets have significant influence on pilling tendency of
fabric samples.
