Compact Spinning

Currently, there are three different systems on the market (Fig. 3.17).

The other staple fiber process is known as the short-spin or compact spinning process. This is a one-step process with relatively slow spinning speeds of about...

For bicomponent fibers, a conventional line is generally chosen, while for spun-dyed fibers, compact spinning is more appropriate. A compact spinning plant requires a normal-sized building, while conventional spinning calls for custom facilities. 

For lower capacities (< 10,000 tons/yr), labor and energy costs are lower with compact spinning. For...

For melt spinning, spinnerets made of steel are used. For the production of filament yarns, these plates have up to several hundred boreholes. Spinnerets for staple fiber production using conventional spinning methods have up to 10,000, and for compact spinning methods even up to several 100,000 capillaries.
