What are the advantages of weft knitting?
The single yarn input allows for production of very thin fabrics at a variety of fabric widths. For unique applications, the production of a tubular fabric can even allow for 3D constructs with minimal or no seams. One of the main benefits to weft knitting is cost.
Do knit fabrics have warp and weft?
Unlike a woven fabric, which is composed of a series of warp (lengthwise) yarns interlaced with a series of weft (crosswise) yarns, a knit fabric is made up of one or more yarns formed into a series of loops that create rows and columns of vertically and horizontally interconnected stitches.
