A Wrap Knitting Fabric is a textile structure consisting of loops made from multiple yarns

A Wrap Knitting Fabric is a textile structure consisting of loops made from multiple yarns (referred to as warp threads) which are interwoven through a perpendicular path. These fabrics have a relatively elastic, soft, and breathable character compared to woven fabrics.

Warp knitting represents the fastest way of producing knitted fabric from yarns. It differs from weft knitting in that each needle loops its own thread and runs vertically down the fabric.

This process is done using a variety of machines including circular knitting and flat-bed machines. The circular knitting machine produces a tube of fabric while the flat-bed machine makes flat yardage.

The fabric produced by these machines can be a plethora of colors, textures, and patterns. It can be a wide range of weights, from light to heavy, and can be produced with a variety of fiber types.

It is used in a variety of applications such as sportswear, thin netting for mosquitoes, tulle fabrics, lace fabrics, and many others. It also has a wide range of industrial uses such as reinforcing concrete and making biotextiles.

Yarn Evenness

The yarn evenness of a knit fabric is an important indicator of the quality of the finished product. It can be measured by a number of indices such as CV value, fine end, slub, and nep. It is also affected by the twist of the yarn, which can be categorized into S twist and Z twist.

For the most part, yarns that have a high evenness have less twist. This can lead to a smoother, more uniform appearance on the finished fabric.

This is because the yarns are twisted at an angle to each other during the weaving process, which helps prevent any slubs or knots from showing on the final fabric. This can also help reduce the overall production time of a knitted fabric.

Several indices of yarn evenness can be used to measure the quality of a knit fabric. These can include the CV value, fine end, slub, nep, and other defects of the yarn.

These indices can be combined together to calculate the evenness of the entire yarn. The more uneven the yarn is, the lower the evenness of the final product will be.

The fine end of a knitted yarn can cause an irregularity of the fabric that could be aesthetically noticeable or could make the fabric more difficult to handle in the production process. It is also important to note that the fine end of a knitted yarn can be harmful to people who are allergic to it or who may have problems with hay fever or other respiratory conditions.

As the blending ratio is significantly influenced by the moisture management and air permeability of a knitted fabric, it is advisable to choose a material that has a low absorbing capacity and good wicking properties. Moreover, materials that have a microporous effect can help the fabric to absorb liquid water and transfer it to the next layer in a quicker way. This is particularly important for sportswear because it can help to improve the comfort of a garment and also reduce the risk of injury.
