Get PriceAir-jet spinning is the modern alternative to ring and rotor spinning. This is the fastest spinning technology for staple fibre yarn production. Applications of air-jet spun yarns are anticipated to grow and therefore wider use of air-jet spinning machines is expected, mainly in the American and Asian markets rather than the European market.
Get Price1 INTRODUCTION. Ioncell® is a new lyocell-type process for the production of man-made cellulosic fibers based on the direct dissolution of a cellulose substrate, preferably a dissolving pulp, in an ionic liquid (IL), air gap spinning of the solution (spinning dope) in a water bath, and a subsequent solvent recovery step in which the IL, H 2 O and impurities generated are separated.
Get PriceDry jet-wet spinning in the lyocell process (Kim et al.2005) In fact, the air gap is a critical element of the operation, with significant changes in the solution, and the spinning ray stretched and oriented (Mortimer and Peguy 1996a,b; Mortimer et al.1996). A highly oriented structure is formed upon entering the aqueous precipitation bath.
Get PriceRotor spinning and air-jet spinning are extensively used; some others have survived in specialist applications. More information on staple fibre spinning was described and discussed by Grosberg and Iype (1999), Lawrence (2003) and Lord (2003).
Get PriceSince its introduction in 1980, air jet spinning has offered yarn manufacturers the opportunity to produce yarn at relatively high production rates.

Get PriceThe spinning nozzle is basically the yarn formation element, i.e. the heart of the Air-jet spinning process. Compressed air at up to 0.6 Mpa enters the actual spinning chamber through 4 small bores, thus creating a very strong air vortex (see Fig. 36). At the outlets of the bores, this air vortex has a rotation speed of up to 1 000 000 rpm.
