How to distinguish the warp and weft directions of fabrics? Next, let Yulia soft bag help you distinguish the difference

how to distinguish the warp and weft directions of fabrics:

1 If the sample of the fabric to be analyzed is selvage, the yarn parallel to the selvage is warp, and the yarn perpendicular to the selvage is weft

2. Warp yarn with size and weft yarn without size

3. Generally, the fabric with high density is warp yarn, and the fabric with low density is weft yarn

4. For fabrics with obvious reed marks, the direction of reed marks is the warp direction of the fabric

5. When one group of several yarns in a fabric is a strand and the other group is a single yarn, the strand is usually a warp and the single yarn is a weft

6. If the twist direction of single yarn fabric is different, Z-twist yarn is warp direction and S-twist yarn is weft direction

7. If the twist of the finished yarn of the fabric is different, most of the twists with large twist are in the warp direction, and those with small twist are in the weft direction

8. If the warp and weft yarn count, twist direction and twist direction of the fabric are not different, the yarn evenness and luster are better for warp yarn

9. For towel fabrics, the yarn with loops is warp, and the yarn without loops is weft

10. The sliver direction of a striped fabric is usually the warp direction

11. If the fabric has a system of yarn with many different characteristics, this direction is the warp direction

12. Leno fabric, warp yarn with twist and weft yarn without twist

13. In the interweaving of different raw materials, generally, cotton and wool are interwoven with cotton and hemp, and cotton is warp yarn; In wool silk interwoven fabric, silk is warp; In wool silk cotton interwoven fabric, silk and cotton are warp yarns; Among the interwoven fabrics of natural silk and spun silk, natural silk is warp; In the interwoven fabric of natural silk and rayon, natural silk is warp yarn

because fabrics are widely used. Therefore, the requirements for fabric raw materials and organizational structure are also diverse, so when judging, it should be determined according to the specific situation of the fabric
