1. During the weaving process, the edge of the fabric must be fastened to both ends of the weft yarn to withstand the strength of the temples, so that the cloth surface of the weave fabric does not produce excessive weft. In addition, the cloth edge also reduces the warp of the warp of the side, improves the degree of friction of the warp and the teeth of the side, reduces the breakage rate of the warp of the side, increases the strength of the edge, keeps the flatness of the cloth and the uniform width, and the edge It is easier to form the entire winding and facilitate the processing of the post-process.

2. In the process of dyeing and finishing, the cloth edge of the woven fabric is also subjected to the pulling force of the cloth or needle, especially the cellulose fiber fabric such as cotton and hemp. In the process of shaping and tentering after mercerizing, it has to withstand a large pulling force. After all, the firm, flat and elastic side structure is a necessary condition for finishing. If the layout of the woven fabric is unreasonable, the fabric will have loose edges, broken edges, tight edges, curling, etc., and a large number of broken edges will occur, and even the finishing process will not be carried out at all. Cause huge losses.

Considerations when woven fabric is edged

1, width. The side tissue is too narrow, the strength is not enough, and the tension cannot be easily absorbed. It is easy to tear the edge and not protect it. The tissue is too wide, which increases the cost of the fabric and affects the fabric's tailorability under a certain width. area. In general, a simple texture of the fabric can be as small as possible, but the width of the same side, the faceted tissue, and the stretch fabric of some of the longer floating length lines are appropriately increased depending on the situation.

2, thickness. The edge thickness of the woven fabric should be as close as possible to the fabric of the woven fabric, so that it is easy to keep the fabric flat, winding, beautiful and evenly stressed.

3, tightness. The hem of the woven fabric is usually slightly tighter than the cloth, but be careful not to be too tight. Too tight will affect the finishing, and the cloth edge can not withstand large deformation in a short time, and even tear the edge of the cloth to make the whole batch of woven fabric invalid; if it is too loose, it will form a weft and form a ruffle. On the other hand, it is easy to have a broken edge during finishing. Therefore, the edge tissue density must be greater than the ground tissue.
