Much like the world around us, the textile industry
is experiencing tremendous change and progress. with this
comes new techniques and systems for manufacturing. Each
year the textile industry is offered many new systems that
are designed to give the industry a competitive advantage
in the areas of production. It is neccesary to evaluate
and compare these new systems to the well established
systems. These comparisons are performed in order to
characterize these new systems into the areas in which they
will be most effective. This thesis research compared and
. .
evaluated a new air jet yarn for weaving to a well
established weaving yarn.
The Murata Twin Spinner is a newly developed and
recently introduced air jet spinning machine. The Twin
Spinner produces two individual yarns and winds them onto
one single package. These packages are sent through a
2-for-1 twisting process that results in a plied air jet
yarn. The Twin Spinner will also be used with a 100
percent cotton fiber. This is the first time 100 percent
cotton has been used in air jet spinning. The Twin Spinner
is also said to offer a cost effective replacement for a
ring singles yarn with a higher quality plied yarn.
Although much research has been conducted on the
actual production of the Murata Twin spun yarn,
.system has had little research conducted on the
this new
yarns
performance in weaving. This research has defined the
advantages for the yarn producer, however it is important
to determine whether this new yarn system offers advantages
to the woven fabric producer. The thesis research that has
been performed is a comparison of a 40/2 Murata Twin Spun
yarn to a 40/2 Ring spun and 20/1 ring spun yarns. The
comparisons were made in the performance parameters of
yarn, slashing, weaving and fabric. The results of the
thesis research are as follows:
1. Yarn Performance: The Murata Twin Spun Yarn is
comparable to both the plied and singles yarn but is
not superior.
2. Slashing Performance: Size penetration and
encapsulation is sufficient at low add-on levels.
3.
4.
weaving Performance: The Murata Twin Spun yarns'
structure enabled· it to weave in the unsized state
and also performed superior to the ring singles yarn
in the low add-on levels.
Fabric Performance: The Fabric test results were
similar to the yarn performance with the Murata Twin
spun yarn being comparable but not superior.
These results can be used to-characterize the Murata
Twin Spun yarn. The size application quality, that is size
encapsulation and penetration, reaches a sufficient level
at low add-on levels. The Murata Twin Spun yarn offers many
possibilities in the areas of unsized and low add-on
weaving. The data in this thesis can be used to determine
the specific areas in woven fabric production to which this
air jet yarn technology can be applied.
