Comparing the results of two self-twist yarns produced using ST roller and air-jet technology showed that the ST roller’s yarn appearance was less hairy compared to the air-jet ST yarn, especially at high pressure (Henshaw 1971). The rate of twist loss with production speed was less with ST rollers than with air-jet technology.
Get PriceFigure 1.22 portrays a typical air-jet spinning system which consists of a 3-over-3 high-speed roller drafting unit, two compressed-air twisting jets arranged in tandem, a pair of take-up rollers and a yarn package build unit. The basic jet design is also shown. This has a central cylindrical channel (the spinning channel) through which the fibre ribbon from the drafting unit passes.
Get PriceThe first self-twist spinning system was devised at the CSIRO laboratories at Geelong, Australia, by Henshaw (1971). To date, the only method of alternate (S and Z) twist insertion into a staple fibre is the Repco self-twist machine (GB Patent 1962, US Patent 1977a) and the WinSpin machine from the Saurer Group.In the Repco system, introduced in the 1970s, the top and bottom twisting rollers ...

One end of a cylindrical copper heat flux sensor was heated by a DC electrical arc and the other end was cooled by a low velocity water jet at 1 atm.
