An experimental study on dyeing of needle‐punched polyethylene‐terephthalate non‐wovens

The dyeing of non-wovens in fabric form is interest for a range applications especially aesthetics. In this work, needle-punched non-woven fabrics were prepared by employing polyethylene-terephthalate (PET) fibres two different linear density and same mean fibre length four ratios three mass areal densities, while keeping all other process material variables constant. objectives the study to find out saturation point profile varying aforementioned and, first time, compare industrially relevant conventional methods (Jet, Package Jigger dyeing) terms physical, mechanical colour fastness properties. case Jet dyeing, was successfully dyed without any structural reorientation sample deformation reported process. Furthermore, tensile strength (in newtons) samples increased, air permeability mm/s) decreased due slight compactness structure after
