Abstract
The present invention is directed to a process for recycling a fabric containing high performance fibers having a tenacity of at least 10 grams per dtex and a tensile modulus of at least 150 grams per dtex, to make a yarn from the fabric. In the process, and the fabric is cut into pieces where the largest dimension is no larger than 15 centimeters. From 30 to 99 weight percent staple fibers are added to the fabric pieces to make a blend and the fibers of the blend are separated and aligned into a sliver, and the sliver is formed into a twisted yarn. This yarn may be used to make a fabric or any other useful article.
