Industrial Knitting

A knitted fabric is made with yarns formed into interlocking loops with the help of hooked needles. Crocheted fabrics are the simplest form of knitting where a chain of loops is constructed from a single thread with the help of a hook. When the interlocking loops run lengthwise, each row is called a wale identified with the direction of warp in woven fabrics. When the loops run across the fabric, each row is called a course which corresponds to the filling or weft in woven fabrics.
Apart from the number of stitches or loops per square inch in a knitted fabric, the needle quality also decide its properties. With varying thickness and length of needles the stitches will also get thicker and longer respectively. There are three types of needles that are mostly used for industrial knitting- the latch needle, spring-beard needle, and compound needle.
Types of Knitted Fabrics

Depending upon the wales and courses, there are two types of knitted fabrics
1.Weft knit fabric, where one continuous yarn forms courses across the fabric.
2.
3.Warp knit fabric, where a series of yarns form wales in the lengthwise direction of the fabric.
Weft Knitting has three basic stitches- Plain-knit stitch; Purl stitch; and Rib stitch. Any other stitch is a variation of these three stitches. basic stitches of hand knitting can be identified with weft knitting. When done on weft knitting machines, individual yarn is fed to a single or multiple needles at a time.

Warp knit fabrics are smooth, sheer, wrinkle resistant, shrink strength and abrasion resistant as such they are very popular with the masses. Warp knit fabrics are considered better than the weft knit fabrics as these fabrics do not ravel easily, are less prone to sagging and have superior dimensional ability.
