Abstract:
A flexible, recyclable and sewable nonwoven textile formed from first fibers having a high temperature polyester core and a low temperature thermoplastic sheath, and second thermoplastic fibers formed from a high temperature polyester. The nonwoven textile is formed by blending the first thermoplastic staple with the second thermoplastic staple, carding the blend into a web, cross lapping the fibers of the web into a mat, needling the mat, heating the mat to a temperature above the melt temperature of the low temperature thermoplastic thereby forming unions between the fibers.
