Abstract
A comparative study is carried out into the properties of
plain woven fabrics produced from a range of ring and rotor-spun
yarns produced at different twist levels.
From the study of the fabric properties, it is apparent that
yarns produced by both spinning techniques have different physical
properties for the same fibre. This is reflected in the behaviour
of the fabrics produced from these yarns. The nature and trend of
these effects are discussed.
As a result of dyeing, the crimp, thickness, cover factor,
fabric dimension and extension are altered, which consequently affects
other fabric parameters such as air permeability, strength, bending
and abrasion characteristics. The changes after dyeing and different
yarn characteristics lead to a considerable difference in fabric
properties.
Based on the laboratory evaluation of the fabric properties,
an attempt was made to predict the end-use performance of the produced
fabrics. It is shown that fabrics produced from rotor-spun yarn
compare favourably with conventional ring-spun fabrics. If the
comparison is made at commercially used twist factors, then it is
shown that the unique properties of rotor-spun yarns may result in
fabrics which offer advantages over conventional fabrics
