Method of Making Articles from Recyclable Fabrics

The invention relates to a method of making an article by recycling a disperse dyed fabric. The fabric is made from a melt-spun thermoplastic polyurethane fiber which contains a co-polymer diol derived from caprolactone monomer and a polyether polyol. The fabric is shredded and then thermally treate...

Zusammenfassung:	The invention relates to a method of making an article by recycling a disperse dyed fabric. The fabric is made from a melt-spun thermoplastic polyurethane fiber which contains a co-polymer diol derived from caprolactone monomer and a polyether polyol. The fabric is shredded and then thermally treated to form granules, which can be melted in an extruder to form an article.
