The level of technology and automation utilized in a manufacturing plant has a direct bearing on the final product quality. At Dhanar Mas Concern, we have the state of the art machinery and the latest available automation systems to reduce human intervention in the manufacturing processes which results into lesser human errors during yarn production.
Opening and cleaning is the first operation which takes place in the spinning mill. The department where cleaning and opening is performed has a funny name, Blow Room, it is called this way because the cotton is transported from one machine to another by blowing it through the ducts. Blow room is combination of machines varying significantly unlike other processes in spinning. The main objective of the blow room is to open, mix, clean and even feeding to the next process, which is carding.
Carding is the next process in the spinning line after the opening and cleaning process. As it’s obvious from the name (CARDING card › Heart) it’s the heart of the spinning. Here the fibres are being straightened and made into the sliver. First time in the spinning process the fibres resembles to the thick rope like strand.
The Trützschler’s TC 11, provide best quality and productivity,
With a carding range of more than 2.8 metres, only Trützschler cards offer optimal quality. The end result was a working width of 1.28 m represents the perfect balance between productivity and efficiency.
.
Drawing is one of the simplest process here, a number of slivers from the carding are stretched to make one sliver. This process is purely done to improve the evenness of the end product. A thin spot in one sliver when mixed with 5 to 7 and some time more sliver becomes insignificant
Rieter’s RSB-D 45 Autoleveller Draw Frame and SB-D 45 Draw Frame produces a high quality and productivity at delivery speeds of up to 1 100 m/min. Excellent scanning precision and autolevelling dynamics result in outstanding sliver regularity. A unique sliver sensor guarantees precise sliver coiling from the first metre. The CLEANtube option ensures clean sliver coiling when processing cotton.
.
This is an intermediate stage before the final yarn is made in the next stage. The problem with the sliver is that it is too thick to put directly into spinning. To make yarn it needs to be stretched gradually the simple/roving is just an intermediate drawing stage, here the sliver is get stretched and slightly twisted to keep the strand intact while transporting to next stage.
The rovings are taken to the ring frame, which stretches the roving to the required thickness and imparts twists to give strength to the yarn.
Stretching is performed by increasing the speed of the roller pairs gradually so the back roller pair runs slower than the middle pair and the middle pair runs slower than the front creating a stretch in the fibre.
The Rieter’s G32 and TOYOTA’s RX300 ring spinning machine have been optimised to achieve a top quality product, form a solid basis for a high and constant yarn quality and its suitable for all conventional yarns from Ne 10 up to Ne 60
In this stage the spinning bobbins is being converted to a packages for better transportation and longer yarn in the package. Also this stage can work as a quality control on the yarn where all thin areas and thick areas can be eliminated for better more even yarns.
