  • Bicomponent spinning
  • Biconstituent spinning
  • Film splitting
  • Integrated multicomponent yarns
  • Cover sun yarns
  • Selfil yarns
  • Aerodynamic spinning

Bi-component spinning

  •  The technique involves extrusion through a spinneret of two different types of the same polymer
  • There are three methods of bicomponent yarn production
    • Side by side extrusion
    • Extrusion through one spinneret enclosed in another
    • Distribution of drops of molten polymers

Bi-constituent spinning

This technique utilizes two different polymers that are combined and extruded in the same manner

Film Splitting

Melt extrusion of the polymer through a wide die but with a very narrow slit to form a sheet of film which is later broken /cracked by mechanical means into a mat of fibers Or embossed with a roller having patterned indentations to fibrillate the film

Integrated composite spinning(ICS)

The process entails passing a monofilament or a multifilament strand (Carrier) through a polypropylene Polymer (binder resin) and then immediately embedding part of the length of staple fibers into the polymeric resin

Different types of staples of different sizes and colors can be used to incorporate desirable properties, effects, and appearances.

Cover spun

The technique wraps fine continuous filament man-made fiber around a core of untwisted natural or man-made staple fiber to produce yarns in a wide range of counts.

Selfil

The self-twisted staple core is initially wrapped with a filament yarn in alternating S and Z phases; a second filament yarn is then wrapped around these in alternating opposite Z and S twists.

Aerodynamic Spinning

This system passes a continuous Multifilament yarn together with staple fiber through a Pneumatic device which causes the filaments to twist and curl entrapping the staple fibers in the snarls.
