ABSTRACT:
Insulating fabric having a knitted base fabric incorporating air-entrapping cells on one or both sides. The base fabric is knit from a high bulk acrylic yarn and a combination polyester and cotton yarn, the yarns being knitted separately in selected fabric courses. The inner face of the fabric is formed of the high bulk yarn, to provide a soft, warm and comfortable interior surface when worn. The outer face of the fabric is formed of the polyester/cotton yarn, which provides a knitted framework for anchoring and stabilizing the high bulk yarn in the fabric. Following knitting, the fabric is subjected to a series of finishing operations which include scouring, padding, drying, napping and calendering. As the result of repeated washings, the insulating fabric of the invention increases in thickness to enhance its heat insulating capability and provide increased warmth.
