Abstract
A method of constructing a double face fabric is provided. The first step in the method is to knit a three dimensional knit fabric which has a first fabric layer, a second fabric layer and a plurality of yarns that interconnect the two layers. The three dimensional knit fabric is prepared using a conventional double needle bar warp knitting machine. Then, the yarn connecting the two layers is cut, resulting in two pieces of fabric having a velvet surface on one side, and a flat knit surface on the other. The flat knit surface is then raised by a process such as napping to pull portions of the pile yarns through the fabric layer to the technical back, in order to form a pair of double face fabrics, each with a first velvet surface and a second fleece surface. Preferably, the fabric is knit so that after napping it can be stretched. In this manner a wide variety of fabrics can be created.
