The difference between the straight, horizontal and diagonal of the fabric, the straight yarn of the fabric is the warp of the fabric. The transverse yarn is in the weft direction and is slightly stretched. The oblique wire is easy to deform, but it is natural and full when it forms a circle.
Stretch the cloth straight (warp), horizontal (weft), and diagonal (oblique) with your hands, and you can clearly feel the difference in deformation ability.
According to the needs of different parts of the clothing, choose different fabrics in the direction of the thread. For example, the length of the pants must be straight. Slanted silk is used for collars and other parts, so that the suit is naturally full.
