Claims27
A process for producing a thermoformable and bondable fabric, the fabric being biodegradable and/or compostable, the process comprising:
- extruding to form a plurality of bi-component filaments comprising one or two polymeric blends, the filaments collectively comprising the fabric,
- wherein the one or two polymeric blends collectively comprise a first polylactic acid and a second polylactic acid, wherein the first polylactic acid (a) comprises a greater proportion of D-configuration lactic acid units to L-configuration lactic acid units than in the second polylactic acid (b) and wherein the melting point of the first polylactic acid is lower than the melting point of the second polylactic acid.
