Waterproof Fabric Supplier introduces how to distinguish the warp and weft directions of fabrics:
1. If the identified fabric has a selvage, the yarn direction parallel to the selvage is the warp direction, and the other is the weft direction.
2. The sizing is the direction of the warp, and the non-sizing is the direction of the weft.
3. The fabric has selvage, the direction along the selvage is the warp direction, and the vertical selvage is the weft direction.
4. For fabrics with obvious reed marks, the direction of the reed marks is the warp direction.
5. For half-line fabrics, usually the direction of the strands is the warp direction, and the direction of the single yarn is the weft direction.
6. If the twist and draw of the single yarn fabric are different, the Z twist direction is the warp direction, and the S twist direction is the weft direction.
7. If the warp and weft yarn characteristics twist direction, and the twist of the fabric is not very different, the warp direction is the yarn with uniform evenness and better luster.
8. If the yarn twist of the fabric is different, most of the twist is the warp direction, and the small twist is the weft direction. 9. In the interweaving of different raw materials, generally cotton wool or cotton and linen interwoven fabrics, cotton is the warp; in the wool and silk interweaving, the silk is the warp; in the wool and silk interwoven, the silk and cotton are the warp; natural silk and silk In silk interweaving, the natural thread is warp; natural silk and rayon are interwoven In the medium, the natural silk is the warp.
