Description and salient Technical features
Banana yarn making machine consists of mechanical softening machine, Staple fibre cutting machine, carding machine, Gill drawing machine and Ring spinning machine. These machines can be used for spinning banana fibres to spun yarn counts in the range of 600 to 60 tex.
Banana fibre mechanical softening machine: This machine has helically fluted top rollers and bottom rollers with a feed lattice for feeding the banana fibre strands. The fibre gets softened because of the crushing action that takes place between the rollers and normally 2 to 3 passages are given for banana fibre.
Banana staple fibre cutting machine: Machine consists of calendar rollers, stationery and oscillating blade. At present the banana fibres are cut in the range of length of 15 to 20 cm.
Banana fibre carding machine: The machine consists of various elements namely conveyor, feed roller, first set of worker-stripper assembly, second set of worker-stripper assembly, doffer, crush rollers, funnel tray, delivery rollers and crimper. Except crush rollers and delivery rollers all the other rollers are clothed with metal pins. The main function of this machine is to clean the mechanically extracted banana pseudo stem fibres by removing pith and gummy matter from the fibre surface and make the fibres suitable for yarn formation on a spinning machine.
Banana fibre gill drawing machine: This machine consists of a set of back roller and front roller, steel combs etc. Four to five slivers are fed to this machine and the slivers are doubled and drafted to required thickness.
Banana fibre ring spinning machine: This machine has 4 spinning heads with a 3/3 slip draft system having top and bottom aprons for controlling the fibre movement. The sliver is drafted to suitable thickness and twist is inserted to the yarn and wound on to a bobbin of 8 inches diameter. The machine has digital display for spindle speed, front roller speed and back roller speed.
|Production/ spindle:||1.0 kg/h for 600 tex/1s Ne yarn|
|Manpower:||3 skilled workers|
Fibre to Yarn conversion cost: Rs.25/kg
Cost of Machinery: Rs.40 lakh
How the new technology will impact the income of the farmers / end users:
Fibre production per year will be around 27,000 kg, if machine is operated 8 hours per day. Assuming a banana fibre production of 600kg per ha, one set of machine requires around 50 ha of banana cultivation.
Banana crop generate huge quantity of biomass in the form of pseudostem, leaves, suckers etc.
At present, this biomass particularly pseudostem is absolute waste in most of the states of India. Not only this, but for disposing pseudostem presently farmers are spending about Rs. 8000 to 10000 per ha.By making banana yarn at village level, farmers can add value to the fibre and earn a profit of Z 40 per kg of yarn and it works out to earning of Rs. 24,000 per ha.
Disposal of pseudostem in a routine ways i.e., dumping on field bunds and burning, disposing in nalla/natural drains etc. causes environmental problems. The yarn making process is totally a mechanical process and no chemicals are used during processing. Apart from benefit to farmers, there is an opportunity for rural employment.
Status of commercialization / IPO rights etc.
Technology is underdevelopment
