Warp Knitting | Types of Warp Knitting | Uses of Warp Knitted Fabric

Warp knitting represents the fastest method of producing fabric from yarn. Warp knitting differs from weft knitting in that each needle loops its own thread. The needles produce parallel rows of loops simultaneously that are interlocked in a zigzag pattern. Fabric is produced in sheet or flat form using one or more sets of warp yarn. The yarns are fed from warp beams to a row of needles extending across the width of the machine.

Types of warp knitting:

 
1) Tricot Knit: Tricot fabric is soft, wrinkle resistant & has good drapability. Tricot knits are used for a wide verity of fabric weights & design. It makes light fabric weighting less than 4 ounce/square yard. Some examples of tricot fabric are sleepwear, boluses, dresses etc.

2) Raschel Knit: The Raschel knit ranks in importance of production with tricot but it makes varieties of products ranging from laces, power nets for foundation garments, swimwear to carpets. Raschel knitting is done with heavy yarns & usually has a complex lace-like pattern.

3) Crochet Knit: This basic stitch is used in hand crochet. This construction is used in a wide variety of fabrics ranging from nets & laces to bed spreads & carpets, various types of edgings or trimmings lace are also produced.

4) Milanese Knit: The milanese stitch produces a fabric very similar to tricot. It can be identified by the fine rib on the face & a diagonal pattern on the back. However, milanese fabric is superior to tricot in smoothness, elasticity, regularity of structure & friction resistance.
