Abstract
Insulating fabric having a knitted base fabric incorporating air-entrapping cells on one or both sides. The base fabric is knit from a bulk acrylic yarn, preferably 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 bulk acrylic 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 and calendering. Preferably, the inner acrylic surface of the fabric is napped prior to 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.
