Because the jeans are generally shrinking after washing, so in the water before the size of the guests asked to add shrinkage
Specific shrinkage can be as follows:
1, cut half yards cloth, with butter pen or ball pen (this will not fade after washing water)
2, draw a horizontal X straight =50cmX50cm box in accordance with the standard wash water wash (must be the same as the future is a wash clothes wash standard)
3, such as the amount of water after washing out the size of the box can be shrinkage
For example: after washing the horizontal X straight =47cmX48cm, then the transverse shrinkage is (50-47) /50=6%, is 50-48 (shrink) /50=4%. and then shrink to the size of it
For example: waist to cross cutting, size 32 "customer requirements, so the pattern size should be 32 / (1-6%) =34" (because the waist of washing water is 34, after washing the size is 34 "X94%=32", it is the requirements of the guests), the patternmaster will be added.
