Synthèse de composites à base de PP recyclé - Argile pour des applications textiles

Abstract : Polypropylene PP is considered to be one of the most promising polyolefin polymer in compounding applications thanks to its good processability and excellent properties, as well as its low cost and density. This polymer is widely used in several applications, such as automotive components, aerospace, plastic parts, food packaging and geotextiles. Nevertheless, the performance of reused PP is proved to be insufficient in many applications, particularly with regard to its thermo-mechanical properties. However, recycled PP could acquire desired properties by incorporating fillers into polymer matrix. The objective of the thesis initially was studied the influence of organoclay on the physical, rheological, mechanical and thermal stability of recycled PP. In the following step, the prepared composite was then made into filamentsvia a melt spinning technique. The morphological and thermo-mechanical properties as well as the dyeability of the prepared filament were evaluated. The objective here is to exploit the elaborated composite in textile applications. Finally, all of its approaches and scientific studies allowed us to control the parameters of PP reuse and to open the way for new applications such as filters for treatment stations of textile dyeing waste in Tunisia.
