Abstract
A fabric made by the method of providing a non-woven batt having flame retardant fibers, stitch bonding the non-woven batt with an elastic yarn, and heat treatment the stitch bonded, non-woven batt. The stitch bonded non-woven batt is exposed to a temperature in a range of 65° C. to 200° C. for a period in a range of 30 seconds to 120 seconds, and contracts in the machine direction in a range of 5% to 65% and in the cross-direction in a range of 20% to 70%. In an embodiment, the fabric is adapted for use as a mattress core cover.
