Calculation Method Of Jeans Shrinkage Rate

[[spleen circumference + foot +4 inch] * pverse contraction] * [[foreign minister (excluding waist) +0.5 inch + foot *2 high) * * direct] + [[waist circumference +5 inch] * pverse contraction] * [[waist height +1 inch] * * *2]}*1.05/ can be wrapped +0.05+0.03

Elastic jean is generally the biggest contraction: 15%. if the elastic denim is bought, it is larger than 15%.

It's two.

A good stretch denim is only about 12% in pverse contraction. But in the formula, it should be multiplied by 1.15 (if you multiply 0.15 in the formula, then it will be wrong. The result is only shrinkage part, no normal usage part). The maximum shrinkage of elastic denim is 5%, so the 1.05. of the elastic denim is larger than that of the stretch denim, which is two.

Cotton denim or non elastic denim: normal shrinkage; 5%, normal direct shrinkage: 3%.

Spleen circumference +

+10, this 4 inch refers to the stop position (that is, the seam in the North), and all the inch figures in the back are all ends (seam).

The waist is multiplied by 2 times because the waist is two stories.

0.05 of the back is the amount of the back bag, and the 0.03 is the amount of the bag.

Note: if the trousers are double curved pants (longitudinal stripe), the formula of the trouser head should be cut out from the formula, then add 0.15 at the last surface.

The size is too large to add 0.2, because the amount of bending pants head is too large, the formula can not be set out.

Note: this formula is applicable to quote the guest, please make sure that the cloth must be lined with paper.

Note: this formula can also be used to convert to CM. The reason is the same.

Note: some trousers are too large in size. Because the cloth width is limited, they can not be discharged normally. They must be misplaced. They are not suitable for this formula.
