The Raschel warp knitting machine is a type of warp knitting machine with a structural feature that the direction of fabric tension and the needle bar plane form an angle of more than 140 degrees. It is commonly used to knit complex organizational structures for warp knitted fabrics such as curtains, tablecloths, bedspreads, blankets, lace trims, women's inner and outerwear, fishing nets, and packaging bags. Raschel machines commonly use machine numbers from 10 to 48 needles/50.8mm, with the highest reaching 64 needles/50.8mm. The commonly used working width is from 1900 to 6600 millimeters (75 to 260 inches), and the widest reaches 9650 millimeters (380 inches). Raschel machines typically use tongue needles, and some machines initially used groove needles.
The Raschel machine uses tongue needles with metal wires or blades. It has a specification expressed in needles per 2 inches (5 centimeters), so a 36-spec Raschel machine, for example, will have 18 npi. Raschelle warp knitting machine is used for lace fabrics and trimming. It is also used to produce outdoor and military fabrics for products such as backpacks.
Modern Raschel warp knitting machines use composite needles. Raschel machines are typically equipped with more guide bars than warp knitting machines. The digit range from 4 to 70 allows these machines to have greater pattern capabilities. Raschel knitwear uses two types of guide bars. The first type is fully threaded and is used to construct ground fabrics. In most cases, 1 to 3 of these guide bars are used. The second type of guide bars is used to apply patterns to the fabric. These bars usually require only one thread per pattern repeat, so only a few threads pass through the entire width of the bar.
Raschel knitted fabrics are made of heavier yarns and are used to produce versatile and flexible fabrics that are more textured and can be used in a wide range of technical textile applications such as automotive textiles, home textiles, underwear, mosquito nets, lightweight coating substrates, sportswear, swimwear, lining fabrics, jackets, and more. Different types of single and double-needle bar Raschel warp knitting machines are now manufactured for a wide range of products from gunny bags to artificial blood vessels. Seamless tube fabrics, pile fabrics, and many other special fabrics can be easily produced on double-needle bar machines using 4 to 6 guide bars. However, by using more guide bars (16 or more), producing artificial blood vessels, patterned pantyhose, and shaped underwear is no longer a problem. The warp-knitted spacer fabrics (WKSF) are a type of three-dimensional textile made by double-needle Raschel machines.
