DREF spinning which is conventionally known as Friction Spinning operates on the basis of mechanical/aerodynamic spinning system with an internal suction and same direction of drums rotation. Drafted slivers are opened into individual fibres by a rotating carding drum covered with saw tooth type wire clothing
The individualized fibres are stripped off from the carding drum by centrifugal force supported by an air stream from the blower and transported into the nip of two perforated friction drums where they are held by suction. The fibres are sub-sequentially twisted by mechanical friction on the surface of the drums and produced yarns result in high resilience with bulkiness and high air permeability.
The Core-Sheath combination produced offers improved resistance, strength and combination of different yarns like copper, stainless steel in core which can be used for various applications.
APPLICATIONS
- 0.6Ne -1.5Ne-filter cartridge
- 7Ne- for filter fabric where the weft of the filter fabric is with friction spun yarn
Due to high air permeability of the DREF Friction Spun Yarn, the dirt holding capacity of the filter cartridge and the filter fabric increases tremendously. It also helps the filtration process with higher efficiency - Friction products such as brake lining, brake shoe, clutch lining etc. are in high demand. Yarn produced through this process is in very high demand. After processing the friction spun ,the other yarns are used to combine on TFO to produce yarns which are used for applications using multifilament glass fibre yarn or UHMWPE as core yarn with Para Aramid fibre as sheath
- Cut Resistant gloves
- Apparel
Other areas where core spun through Friction Spinning are used in shoes, ropes and industrial cable manufacturing. Filler cartridge for liquid filtration is also effectively made with these yarns. Secondary Carpet Backing for tufted carpets can be produced with waste fibres in this spinning system. Upholstery, Table cloths, wall coverings, curtains, handmade carpets, bed coverings, and other decorative fabrics can be produced economically by DREF Spinning System. Heavy flame-retardant fabrics, conveyor belts, clutches, brake linings, friction linings for automobile industry, gaskets are some other examples where the DREF yarns can be effectively used.
