The History and Present of Friction Spinning
作者:kukuat 日期:2010-4-20 10:21:33
The “friction spinning ”is a new spinning method invented by Dr. Ernt Fehere of Austria. The friction spinning adopts the combination method of mechanical and aerodynamic, which sucks and collects the fibers on the perforated drums, A suction slot is fixed inner the perforated drums, The perforated drums rotate and rub the fibers into a rubbing twisted yarn with the help of drum friction forces.
In 1973, Dr, Ernt Fehere first applied for a patent named by the abbreviation of his name:"DREF" spinning. Before and after that, although there are many kinds of spinning machines similar to the friction spinning methods such as: inside and outside cylinder twister in the Czech Republic , special disc friction twister in Germany. plane netted friction twister in Japan and master spinner friction spinning in the UK, But all of these machines have not been put into production or marketing for some reasons.
China started researches on friction spinning in 1979. In 1983, friction spinning machines FS-1 and CS-1 as well as others were manufactured in several provinces of China, which also have not been put into the market.
The first machine DREF-I was produced in 1974, After improving the DREF-I , a new friction spinning machine DREF-II was exhibited at ITMA in Italy in 1975. The DREF-III machine was also presented in 1978. Up to 1986, the DREF machine series sold more than 6000 spindles( one machine has 3 or 6 spindles) were distributed over 60 countries.
The friction spinning method can only spin very much coarse yarns, the adaptable materials and the spinning range are extremely limited, So , this spinning method has not got more development. But the Fehere Co. has all along made unceasing efforts to put out new friction spinning machines: DREF-2000 and DREF-3000 after 1990 .However , these machines still remain in coarse yarns and narrow varieties.
From the principle of friction spinning , it can be known that DREF possesses high productivity under low running speed. This is its unique feature and may have prospects, So, in this chapter, we only introduce the DREF friction spinning to give enlightenment in this area.
