| 13 Oct 2009 by Priyank It affects Torsional Rigidity of the Yarn. Torsional rigidity means ability to twist. As fiber fineness increases, torsional rigidity of the yarn reduces proportionally. Thus fibers can be twisted easily during spinning operation. ... My Textile Notes - http://mytextilenotes.blogspot.com/ |
| 26 Jul 2009 by Priyank to reclaim the waste fiber, the fabric is subjected to garnetting and low tension carding, before spinning it in the form of yarn and using it to weave fabric. the only thing remains to be seen is the techno-commercial viability of such ...

| 17 Jun 2009 by Priyank dmf- dimethyl formamide) and extruded through spinnerettes into a coagulating bath ( water) as in wet spinning or into an atmosphere to remove the solvent as in dry spinning. properties strength: 0.55-1.0 gpd ... My Textile Notes - http://mytextilenotes.blogspot.com/ |
| 14 Jun 2009 by Priyank spinning : polypropylene is melt spun. the filaments are extruded at 100 deg c above the melting point, cooled in air chamber and collected on bobbins. the filaments are hot drawn (polyethene- cold drawn) and twisted into yarns. ...

| 31 May 2009 by Priyank It is heated and extruded into a heated spinning cell. A heated evaporating medium such as air, nitrogen or steam moves counter current to the travel of filaments and removes the solvent to take it to a recovery unit. ...

| 29 May 2009 by Priyank Spinning of Polyester Fibres The polymer is extruded in the form of a ribbon. This ribbon is then converted into chips. The wet chips are dried and fed through a hopper, ready for melting. This molten polymer is then extruded under high ... My Textile Notes - http://mytextilenotes.blogspot.com/ |
