The difference in warp and weft directions of fabrics
May 29, 2024
1. If the identified fabric has fabric edges, the direction of the yarn parallel to the edge is the warp direction, and the other side is the weft direction.
2. Sizing is in the direction of the warp, while non-sizing is in the direction of the weft.
3. Generally, the fabric with higher density is warp direction, while the fabric with lower density is weft direction.
4. For fabrics with obvious reed marks, the direction of the reed marks is warp direction.
5. For half thread fabrics, the direction of the ply is usually warping direction and the direction of the single yarn is weft direction.
6. If the twist of a single yarn fabric is different, the Z-twist direction is the warp direction, The S-twist direction is the weft direction.
7. If there is no much difference in the warp and weft yarn count, twist direction, and twist of the fabric, then the yarn with uniform dryness and good luster is warp direction.
8. If the twist of the finished yarn of the fabric is different, the higher the twist is mostly warping direction, and the lower the twist is weft direction.
9. For towel fabrics, the yarn direction with loops is warp direction, while those without loops are weft direction.
10. Stripe fabric, the direction of the stripes is usually warping direction.
11. If a fabric has a system of yarns with multiple different characteristics, this direction is the warp direction.
12. For leno fabrics, the direction of twisted yarn is warp direction, while the direction of untwisted yarn is weft direction.
13. In interwoven fabrics of different raw materials, cotton wool or cotton linen interwoven fabrics, cotton is warp. In woolen and silk interwoven fabrics, silk is warp. In woolen and silk and cotton interwoven fabrics, silk and cotton are warp. In the interweaving of natural silk and silk, natural silk is warp. In the interwoven fabric of natural silk and rayon, natural silk is warp. Due to the wide range of uses and variety of fabrics, there are also various requirements for fabric raw materials and organizational structure. Therefore, when making judgments, it is necessary to determine based on the specific situation of the fabric.
