Most pants are twisted with shaka and twill fabrics. It is mainly caused by improper silk thread.
1. When weaving in the weaving factory, the weft of the cloth is inclined and the trouser legs fall off.
2. The silk thread is not straight when cutting the sketchpad.
3. The mesh cloth is unevenly stressed.
4. When cutting, the knife is biased, resulting in crooked line.
5. Due to specification errors or other reasons, the front and back film sizes are different.
6. Uneven sewing force.
7. The tangential potential of double stitches is too great.
