What Is Weft Knit Fabrics ?
2022.08.22
Knitting is the process of construction of a fabric by interlocking loops of yarn by means of hooked needles. Knitted fabric consists of horizontal rows known as courses and vertical columns of loops known as Wales. Knitted fabrics are porous having insulated air pockets giving warmth when worn. Knitted fabrics are very absorbent, wrinkle resistant and lightweight. They shrink more than woven fabrics unless shrinkproofing techniques are used.
Weft knit structures
Weft Knit fabric consists of horizontal parallel courses of yarn generally characterized by the structural threads being perpendicular to the selvedge of the fabric. These are produced in either tubular or flat form; usually elastic & highly drapable. Some weft knitted fabrics are Circular Knit, Flat Knit, and Hosiery Knit. Whatever their structure, all knit fabrics are composed of three basic stitches: Knit & Purl, Tuck and Miss (float or non knit) which are foundation of all weft knitted structures.
Plain or Purl Knit Stitch can be produced in flat knit, tubular, or circular forms. Basic knit stitch is a plain stitch while Purl is basically reverse of a basic plain knit stitch. This plain flat knit is also called jersey stitch. Knit stitch (technical face) is a Vshaped appearance where the shanks are above and the feet are below the head of preceding stitch. Purl stitch (the technical back) is of the semi circle appearance where the legs are below, and the feet are above the head of preceding stitch. The loops form vertical rows, also called Wales, on the fabric face, giving it a sheen, and crosswise rows, also called courses on the back.
Tuck stitch
Tuck stitch, is a knit stitch which creates an open space in the fabric. It is made when a needle rises to take a new loop without casting the old. It consists of a held loop and a tuck loop both of which are intermeshed in the same course. A tuck loop always faces the technical back of the knitted structure.
Missed stitch
Missed- stitch or Float stitch is so called as it produces a float of yarn on the fabric's wrong side. Also termed as a miss stitch as it is a length of yarn not received by a needle and connecting two loops of the same course that are not adjacent wales.
