Knitting is two types. They are: warp knitting and weft knitting. Weft knitting is the more diverse, widely spread, and larger of the two sectors, and accounts for approximately one-quarter of the total yardage of apparel fabric compared with about one-sixth for warp knitting. In weft knitting, the yarns fed into the machine form loops across the width of the fabric. In a weft knitted structure, a horizontal row of loops can be made using one thread and the thread runs in the horizontal direction. Most of the knitted fabrics are produced by weft knitting. Process flow chart of weft knitting is as follows:
Flow Chart of Weft Knitting
Knit fabrics are mainly constructed by interloping one or more sets of fiber or yarn. The most common examples of clothing utilizing knit fabric are socks. Knitting has a versatile manufacturing process. As an entire product could manufacture on a single knitting machine. Knitting is much faster than weaving. Due to the looping, more yarn is required to manufacture a knitted product than a comparable woven product.
Knits are very comfortable fabrics. The loop structure of the knit fabric contributes to elasticity beyond what is capable of the fibers alone. It’s prone to snagging and has a higher potential shrinkage than a woven. The loop structure of the knit provides many cells to trap air, and thus provides good insulation in still air. Seamless knitting fabric offers numerous advantages to consumers and producers. Such as better fit, quick turn-around time, improved performance characteristics, consistent quality reduced system costs, and so on. In this way, knit fabric is establishing intimate clothing. Its an extension of the technology to outerwear that has been slow to attract consumers.
