Mesh refers to a fabric with meshes. The types of mesh are divided into: woven mesh, knitted mesh and non-woven mesh. The three types of mesh have their own advantages and disadvantages. Woven mesh has good air permeability and is often used in the production of summer clothing. Running shoes and tennis shoes use large areas of mesh in order to achieve breathability. Mesh products are also used in the tongue part of basketball shoes. Woven mesh has white weave and yarn-dyed weave, and has good air permeability. After bleaching and dyeing, the cloth is very cool and can be used in summer clothing, especially for curtains, mosquito nets and other products. The mesh size is the same for printing, filtering, etc.
There are three kinds of weaving methods for woven mesh:
(1) Using the change of the jacquard weave or the method of reeding, the warp yarns are grouped into groups of three and penetrate a reed tooth, and the fabric with small holes on the cloth surface can also be woven, but the mesh is easy to move and the structure is unstable, so Also known as false leno;
(2) Use two sets of warp yarns (ground warp and twist warp), twist each other to form a shed, and interweave with the weft yarn (see leno weave). Among them, the twisted warp is twisted on the left side of the ground longitude by using a special twisted heddle (also known as a half heddle), and after one or five weft insertions, it is twisted to the right of the ground longitude. The mesh-shaped holes formed by the interlacing of weft yarns have a stable structure and are called lenos;
(3) Plain weave and square flat weave to form meshes (screens) by using reed tooth density and weft density. Knitted mesh is also divided into two kinds, weft knitted mesh and warp knitted mesh. The finished product is called by many names.
Second, the classification of mesh
Mesh is mainly divided into three categories:
1. Collar accessories, such as velvet, bk cloth;
2. The main material mesh, used in the exposed part of the upper surface, is light and has good air permeability and bending resistance, such as sandwich mesh;
3. Lining accessories, such as Lixin cloth. The main features are abrasion resistance and good air permeability.
Third, the application of mesh
In order to achieve the effect of light and breathable, running shoes and tennis shoes will use a large area of ​​mesh; and the tongue part of basketball shoes also uses mesh products, and other parts rarely use mesh.
Mesh is a special upper material for shoes that require light weight and breathability, such as running shoes. Simply put, it is a shoe upper made of cloth, but of course it is strengthened by sports. Generally, special fibers and scientific high-strength network design are used. The woven material upper made of 3D mold has the best breathability and elasticity. So as to make it easy to fit, this is the running shoes that nike has launched now without shoe size, and it is also lightweight. In addition, it is convenient to use various dyeing and other means to make various fashionable and individual styles. It is understood that every year nike uses this series to set off a fashion trend, just like the current new element series.
Since 2001, the fashion concept of woven uppers has been proposed, which can be said to be a material with various patterns. However, the disadvantage of mesh is that it is “too soft”. It is basically not unsupportive, and it is too sensitive to the environment such as sweat, and it will be scratched or broken by hooks. After all, the material is cloth. Therefore, mesh is generally used for shoe bodies such as running shoes that strongly require breathability and lightness.
Generally speaking, there are two kinds of mesh materials at present, one is dynamic 3d mesh lycra spandex-mesh made by 3d extension technology, which uses dynamic elastic fiber, just like the kind used on inner boots and shoe covers (Lycra). The comfortable material with strong stretch and elasticity in the direction is also widely used in almost all light running shoes, such as the new element series of air presto gym, butterfly in the wind, air jet flight, presto cage and so on.
