Summary: | The dispersion of clays at the nanometer level is known to induce a significant improvement in mechanical properties, flame resistance and barrier properties, compared with pure polymer. Application of ultrasound in polymer processing can be used to improve additive dispersion in polymer melts and solutions but may also initiate chemical reactions and modify the rheological and mechanical properties. This thesis studies the effects of applying ultrasound to the molten fibre-forming polymers, polypropylene (PP) and polyamide 6 (PA6) containing nanoclay and flame retardant additives in order to assess whether improved dispersion generates improved flame retardant properties of derived fabrics. |
