Understanding Knitting: Weft vs. Warp

Overview of Knitting Techniques

• Knitting is defined as the intermeshing of yarn into loops to create fabric, utilizing two primary systems: weft and warp.

• Weft knitting involves forming loops horizontally with adjacent needles, primarily using circular or flatbed machines.

Weft Knitting Details

• Circular knitting machines produce a tube of fabric by completing one course for each yarn fed during one revolution.

• The structure consists of horizontal rows called courses, measured in courses per linear unit (e.g., five courses per inch).

• Vertical columns formed by the same needle over successive cycles are known as wales, also measured per linear length (e.g., five wales per inch).

Introduction to Warp Knitting

• Warp knitting differs from weft knitting by forming loops vertically; it requires separate lengthwise yarns wound onto a beam.

• Each needle typically needs its own warp yarn; thus, 1,000 needles require at least 1,000 warp yarns for basic fabrics.

Characteristics of Warp Knitting Machines

• Individual needles knit simultaneously across the machine's width, producing various fabrics like tricot and raschel through vertical feeding of warp yarns.
