Bi-ply fabric construction

摘要

A knitted fabric for winterweight garments comprising two confronting webs, one overlying the other and united at intervals by a stitch of the yarn of one web engaging the other web. One of the webs has thick and thin yarns grouped in adjacent courses, the grouped courses of thick yarns alternating with the grouped courses of thin yarns to produce a ridged effect in the web. The thick yarns produce ridge lines and the thin yarns intermediate said ridge lines produce air-entrapping channels in the one web. The other web is preferably smooth on both surfaces. When fabricated into a garment the ridged web is on the inside and the smooth web is on the outside of the garment.
