The Blow Room
The blow room is the first stage or the first process in the short staple spinning. The name 'Blow Room is given to this stage because of the air currents that are commonly used during the processing of fibres The blow room the fibre mass is progressively opened, cleaned and mixed This is done by using a large number of machines. In each of these machines used in blow room if the actions are too severe of sudden then fibre damage will occur
Faction of blow Room
Fibre Opening:
The tightly packed fibre bales
received from the ginning mills have to be opened by converting the larger
fibre tufts into smaller ones and ultimately converting the smaller tufts into
individual fibre form.
Cleaning:
All the natural fibres
including cotton have considerable amount of impurities in them which have to
be removed to produce a clean yarn.
Mixing/Blending:
The properties of the
cotton fibres differ from each other from bale to bale and from fibre to fibre
so in order to obtain a homogenious and consistent quality yarn. they need to
be thoroughly mixed together. Sometimes in order to have a desired quality at
the right price high quality cotton fibres are mixed with low quality fibres
Preparation of
feed for the next stage:
The end product of the
blow room should be compatible with the next stage of spinning i.e. carding The
feed to the carding can be either given in the form of lap or in direct chute
form
