Effect of maleic anhydride grafted polypropylene compatiblizer in enhancing the properties of Polypropylene/ Poly lactic acid polyblend fibres
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 5
Abstract
In the present work, the effect of maleic anhydride grafted polypropylene (MAPP) as compatibilizer on dyeability properties of polypropylene (PP) and polylactic acid (PLA) polyblend fibres is studied. The PLA content in the polyblend fibres were kept constant at 5% and MAPP content was varied from 1-5% and its role in influencing the dyeability of fibres was studied by investigating the changes in the internal structure of the fibres. For 5% PLA content in the blend fibre, addition of MAPP further enhanced the dyeability in the range of 16-23%, along with good wash and light fastness properties. The compatibility between the polymer blend also increased with improvement in tenacity. The increased dyeability is attributed to the reduced crystallinity and increased polarity of fibres due to the presence of maleic anhydride. Although reduced crystallinity led to reduced thermal stability, it was well within the acceptable limits.
