What is the meaning of warp and weft? What is the difference between warp weft?

The warp yarns are yarns in the direction of parallel hem in the woven fabric. It has a large strength, generally has a large twist, good elasticity, high strength, less hairiness and tight and firm.

The weft yarn is a yarn in the direction of vertical edging in the woven fabric. The strong requirement is lower than the warp yarn, and the twist is generally lower than the warp fullness, softness, even strip, and less appearance.

The yarns of the two systems (or directions) are perpendicular to each other and are interwoven in a certain pattern to form a woven fabric. The two systems (or directions) are the warp system (or warp direction) and the weft system (or weft direction).

The different ways in which warp and weft are interwoven have many different appearance characteristics. The law when warp and weft are interlaced is defined as the texture of the fabric, which is usually expressed by the organization. Each vertical line represents a warp yarn, and each horizontal line represents a weft yarn. Each vertical line intersects with each horizontal row to form a small square. This small square represents an organization point, which is the overlap of the warp and weft yarns, where the overlap or the warp yarn is above the weft yarn, or the warp yarn in the weft yarn factory. Face, either an organized point or a woven point.

In general, the tissue points are marked, etc., to distinguish between the tissue points and the weft tissue points, so that we can more easily understand and understand the woven fabric structure.

Organic fabrics are made up of a number of textures of these fabrics. It is easy to recognize woven fabrics by understanding the basic fabric texture. In these organizational charts, there are sometimes many points of organization, and sometimes there are many points of latitude.

In a complete fabric texture diagram (the pattern of yarn interlacing in the fabric is complete when it is repeated), if the tissue points are more than the weft tissue points, the fabric is a warp fabric; if the weft tissue points are more than the tissue The dots are weft fabrics, which are all different fabrics. If the tissue point is equal to the weft tissue point, it is the same fabric. The greater the distance between adjacent tissue points on the same yarn (i.e., the length of the yarn floating on the surface of the fabric), the softer the fabric.
