Warp Knitting Fabrics can be produced in a variety of patterns

Update:May.11 2023
Warp Knitting Fabrics can be produced in a variety of patterns. The most common types are tricot, mirror satin, powernet and satinet. They are used in intimate apparel and shape wear.

Miss-lapping structures have been developed to improve moisture management. This also improves air permeability. However, it reduces one-way transport property and the ability to form a multilayer structure.

Types

There are several different types of warp knitting fabrics available. These include tricot and raschel, which are made using latch needles, and powernet, which uses bearded needles. The basic pattern of warp knitted fabrics is parallel yarns that zigzag along the fabric’s length, with each loop securing the end of the previous wale. This allows for substantial isotropic stretch, but also limits one-way transport properties.

The length of the underlap determines the stability and strength of a warp knitted fabric. A longer underlap increases width-wise stability and strength, while a shorter underlap reduces the lateral stability of the fabric.

Length of the underlap

The length of the underlap is an essential part of warp knitting fabric design. It defines how much yarns interlock with each other. A longer underlap increases lateral stability and strength, while a shorter underlap reduces it. Moreover, the underlap also influences the fabric weight.

The ordinary two guide bar warp knit structure shows one yarn (threaded on the front and back guide bars) on each side of the fabric. This means that for a single-needle bed warp knitting machine, the blue yarns on the front guide bar will show on face side and back side for four courses.

Fabric weight

Fabric weight is an important factor when purchasing a piece of fabric. The higher the fabric weight, the thicker and heavier it is. Fabric weight can be measured in either oz/yd2 or gm/cm2. Fabric weight is not the same as thread count. Thread count indicates the number of threads in a square inch. The higher the thread count, the higher the fabric weight.

Warp knitting is the most popular method for producing fabrics. It is used to create fabrics like tricot and raschel fibers. These fabrics have a smooth surface and have little or no vertical stretch but varying degrees of crosswise stretch. They are also run-resistant and don’t ravel.

One of the most common uses of warp knitted fabric is to make sportswear linings and leisure clothing. It is also used in industrial applications such as reinforcing concrete and making bio textiles. Based on application, the global warp knitted fabric market can be categorized into shoe and apparel textiles, home and furnishing textiles, and technical textiles.

Fabric properties

The fabric produced by warp knitting is much more stable than woven fabric, making it an ideal choice for use in clothing. It can be machine washed with less risk of shrinkage. It is also easier to shape than woven fabric. It can be produced from a minimum number of yarns, even just one.

There are many applications for this technology, including medical and industrial textiles. It is the fastest method to produce fabrics from yarn, and can be used with a wide range of materials. It can even be knitted from brittle material such as carbon or glass.

In order to increase the comfort properties of warp knitted fabrics, engineers are investigating the effects of different yarn combinations on fabric structure. In particular, they are examining the effect of the blending ratio on fabric moisture management. In addition, they are examining the effect of the miss-lapping structure on fabric structure. The results show that the long float at the back side of sample I formed by miss-lapping can improve moisture transport and water vapor permeability.
