Preparatory Department
Everything related to textiles begins in the Preparatory Department where cotton bales are opened and fed into the blow room machines. The cotton goes through different rollers so that the vegetable matter and dust materials are thoroughly removed. Clean cotton is then fed into the carding machine. Carding machine segregates the cotton and converts them as slivers. The cotton passes through the flats, cylinder, doffers, lickerin, redirection rolls, crusher rolls, crude rollers and delivery calender rolls. During this process the dust settles in these rollers and a good cotton sliver comes out. These deposited dust need to be routinely removed.
The ribbon lab machine consists of the drafting zone rollers, doffing zone and creel zone. The dust deposited here during the conversion of sliver into ribbon needs to be cleaned. This is a vital process and thus, removal of dust on regular basis is mandatory.
The cleaning requirement of the preparatory department include:
- Routine sweeping to remove the fine dust and fluff material
- Vacuuming of the processing machines cotton contact roller / zones to remove dust, fibre and waste materials
- Cobweb / Roof / side wall dusting
All the above mentioned processes are dry cleaning processes and no wet cleaning is involved.
Coimbatore based Gangothri textiles and KPR mills employ Roots TTS wide area V-Sweepers for sweeping floors made of fine concrete and stone fashioned. The cotton dust, stones and sand particles are effectively swept. These mills also use Curved brush with 11-metre telescopic pole for effective removal of cobweb and deposited dust.
An effective vacuuming system absorbs dust, fly and fluff. Roots Delfin AS30 vacuum is being used at LMW group Super Sales India Limited mill. “The cotton dust is sucked during the cleaning process and collected into a nylon bag which can be disposed off regularly. The blower is fitted in the lowest part of the vacuum unit. The hopper is specially designed in such a way that the fluff and dust deposits evenly at the bottom. This facilitates optimum utilisation of the hopper and results in continuous and longer operations hours,” explained Balathandayutham.”
