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...

Beschreibung
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. La invención se relaciona con un método para elaborar un artículo al reciclar una tela teñida dispersa. La tela se elabora de una fibra de poliuretano termoplástico hilada por fundido que contiene un diol de copolímero derivado de un monómero de caprolactona y un poliol de poliéter. La tela se tritura y después se trata térmicamente para formar gránulos, que pueden fundirse en una extrusora para formar un artículo.
