Spinning technology is probably one of the oldest technologies invented by humans in which animals, plants, and synthetic ﬁbers
are drawn out and twisted to form yarn. In this, India is one of the chief producers and purchaser of cotton in the world. The Indian Textile Industry has an overwhelming influence on the economy of the country.
In spinning industry
, ring-spinning is one of the most used techniques that is still being used for many applications such as high strength yarn productions, and ﬁne count yarn. It is universally applicable for any material spun. However, ring-spinning has some drawbacks such as travelers’ high-speed which damages the ﬁbers, high energy consumptions, low production rate as a result of which there is a need for some recent advancements in ring-spinning technology. The new winding process is required to make bigger packages and more signiﬁcant expenditure on machine maintenance.
Blowroom process undergoing perfections
In the present day, the blowroom process in spinning technology has undergone a signiﬁcant degree of changes in terms of recovery of good ﬁbers, degree of opening, the intensity of cleaning including reduced number of machines, and removal of a large number of contaminants. The quality of yarn depends upon the detection and removal of contaminants from cotton lint. The contaminants similar to that of cotton such as white contaminants present in the cotton ﬁbers are difﬁcult to identify and separate during cleaning and opening, and it requires efﬁcient detection methods.
During the processing stages, a machine vision with an appropriate algorithm offers an excellent solution for detecting and removal of contaminants. The primary purpose of the blowroom is opening and cleaning of textile material without any considerable loss of ﬁbers. The use of the opening is to increase the volume of the material and to remove the impurities. The increase of opening and cleaning intensity also increases the neps level and ﬁber loss. And these are the reasons why finding the correct process has become a necessity.
Neps removal efficiency being improved with C51
The removal of neps efﬁciency in C51 is much more as compared to other cards machine. The C51 Card machine removes 57 per cent more neps as compared to other machines. This could be due to better ﬁber parallelization and orientation in the sliver of the card. Also, because of this reason, the neps percentage in the yarn produced from the sliver of the C51 card becomes lower when compared with other card machines. With improvement in card technologies, neps removal efﬁciency also improves.
On the simplex machine, the slivers are subjected to the attenuating process, and a small amount of twist is received by slivers and followed by winding on bobbins. This machine produces roving for the ring frame.
