| Abstract | ||
| Polypropylene fabrics are important for the woven or nonwovens market. PP fabrics have wide applications in our life . PP are difficult to be dyed by conventional dyeing methods , since they have no reactive functional groups in their chemical structure. For the above reasons , PP fabrics are modified by different methods including the following: I- Blending PP chips with other polymers with different ratios of PTT, PE, PA,EVA, PET,PS etc..prior or during melt extrusion . II-Dyeing PP using disperse dyes in superfacial carbon dioxide . III- Mass coloration of PP by melt extrusion with organic , inorganic pigments or metallic additives . V- Modification of PP by radio- grafting technique. IV- Dyeing PP by or other means . | ||
