TISSUE
Tissue is a textile fabric consisting of at least two thread systems, warp and weft, which cross each other at an angle of exactly or approximately 90° when viewed on the fabric surface.
Each of the two systems can be made up of several types of warp or weft (e.g. basic, pile and filling warp / basic, binding and filling weft). The warp threads run in the longitudinal direction of the fabric, parallel to the edge of the fabric, and the weft threads run in the transverse direction, parallel to the edge of the fabric.
The threads are mainly connected to the fabric by friction. In order for a fabric to be sufficiently non-slip, the warp and weft threads usually have to be woven relatively densely. That is why, with a few exceptions, the fabrics have a coherent appearance.
To sew fabric, positive displacement needles are always used and never a cutting point.
KNIT/MESH WEAR
Knitwear refers to textiles in which a loop formed by a thread is looped into another loop. The resulting meshes can be formed using one thread or multiple threads.
This distinguishes knitted goods from woven fabrics, in which the surface is produced by crossing two thread systems, and also from nonwovens, in which a loose fibrous web is bonded, for example by heat.
Compared to woven fabrics, knitted fabrics are characterized by higher stretchability, elasticity and, as a result, less creasing.
When it comes to knitwear, a distinction is made between knitwear and warp-knitted fabrics. Knitwear is produced using single-thread technology (knitted fabrics and warp-knitted fabrics) or warp-thread technology (multi-threaded warp-knitted fabrics and warp-knitted fabrics).
To sew knitwear, needles with displacement points are always used and never a cutting point.
