We have done many counts, strength and twist tests - which are considered the most important physical properties that determine yarns quality specification - on cotton yarns at the industrial researches& tests center. The researcher has depended on t
his tests results to find out formulas which match between physical properties of yarns, starting from common formulas then he has proved them by analysis of results that we got from graphic tests instruments, then we have figured out proportion constants between these physical properties from curves that we have got by tests results exemplification and we have shown if these constants describe common constants or new constants.
Bleaching process of cotton fabrics consider an important and
sensitive operations in wet chemical treatments of cotton fabrics,
mercerization is not less important than them and that in cases in which
is made necessary, but from the problems of t
hese processes are long
time and consumption of energy, but the ultrasound energy contribute
to reduce these problems.
