Abstract

Composite nonwovens have been prepared from bagasse and bioderived poly(hydroxy alkanoate)s. Citric esters were used to plasticize and lower the processing temperature of bio-polyesters. Depending on the ratio between the fibers and mechanical stabilizers the materials were classified as polymer-stabilized composite nonwovens or fiber-reinforced polymer boards. Non-durable (washable) fire retardant formulations have been applied to compositions containing bioderived polyesters. Fire retarding efficiency has been evaluated from the value of the oxygen index. Samples of composite nonwovens and of reinforcing bioderived polymer have been subjected to degradation in aerobic and anaerobic environments. Biodegradation has been assessed based on mass loss and by changing of morphology (SEM and stereo-microscopy) after submission to biodegradative conditions.
