What are the advantages of warp knitting?
In general, warp knitted fabric is more stable than weft knitted fabric. By modifying its structure the warp-knitted can be as good as woven fabric. ii. The warp knitted fabrics are thinner than double knitted fabrics and the loops are smaller than double knitted fabric.
What is weft and warp knitting?
Weft and warp knitting are two different knitting techniques that result in various types of fabrics. The main way to distinguish the two types is that weft knitting has the yarn run back and forth while warp runs the yarn up. and down. This difference can create two entirely different end products.
Which yarn is not recommended for warp knitting?
Spun yarns are not used frequently in warp knitting. These yarns are composed of short fibers twisted together to form the structure. The yarn is not as strong or uniform as filament yarn and some of the fibers shed from the yarn and form a contaminant on the warp knitting machine.
What is an example of a warp knit fabric?
The two common warp-knit fabrics are tricot and raschel (Fig. 10.9). Tricot, solely composed of knit stitches, represents the largest quantity of warp knit. It is characterized by fine, vertical wales on the surface and crosswise ribs on the back.

What are the main differences between tricot and raschel knitted fabrics?
Raschel machines are more versatile and are used for fancy pattern work, whereas Tricot machines are less versatile in styling and designing. Raschel mills are smaller whereas Tricot mills are larger and more likely to be integrated mills.
