I am a sweater manufacturer. I want to learn how to write sweater threats. I don't understand the calculation formula after reading it. Can you explain them one by one? thank you

Common formula for calculating the number of sweaters:

The calculation order of sweater threat number: back-> front-> sleeve width-> lower column.

Inverse amplitude calculation formula:

Back chest width = chest width x body square.

The number of stitches in the back hem = the width of the hem x the square of the hem.

Rear hem height = hem height x hem right-angle rotation.

Total revolutions of back length = (length-shirt foot height) x body revolutions squared+sewing consumption.

Back shoulder width = (shoulder width-correction value) x body square.

Knowing the style and wool requirements, first try to knit a piece of cloth, and measure the number of needles in one inch or 1CM on a flat cloth.

Extended data:

A sweater has a big body, a back and two sleeves. There are four pullovers and five sweaters. Weaving refers to weaving these parts on the machine. Woven pieces are generally divided into mobile phone woven pieces and motor woven pieces (computerized flat knitting machine). Mobile phones use hand knitting machines to knit wool into shirts, and you can knit any pattern without sewing the whole shirt, because mobile phones can knit the whole shirt, including collar stickers, chest stickers and bags.

Cut the cloth into the required shape according to the pattern. Most of the motor blades need to be cut, most of the sweaters are cut by hand, and the solid color cloth woven by cylinder can be cut by electricity. Mobile phone weaving rarely needs cutting, except for some styles.
