The formula for the consumption of sutures is: F=M(a+b)×n
The number of stitches in the formula M: 1 Omm; a: the distance of the stitch, mm, b: the thickness of the stitched material, mm, n: the total length of the stitch to be stitched, mm.
For example, the length of the rear seam of the boot to be sutured is 280 mm, 5 stitches per 1 Omm, and the thickness of the boot is 3 mm, and the amount of suture is calculated.
According to the formula, we can know that M = 5 needles, a = 1 O ÷ 5 = 2mm, b = 3mm, n = 280mm, generation eight formula: F = M (a + b) × n = 5 × (2+3) × 280. 7 ∞ Omm. 70cm
The line consumption is 70c m. But this is only one side of the amount. All the upper and lower lines must be multiplied by 2, ie, 70×2=1 40 cm. In addition, when setting the quota for consumption,
We must also look at the number of times that we have to stop the line and add the amount of thread consumption. · The old shoes at home are like this to transform big spikes · Old shoes don't stupidly throw away so that the shoes "open" Put a physical insurance on your shoes · How to clean the matte surface of the shoes? · Breathable, antibacterial, deodorizing socks with it to avoid off shoes ·Sports shoes's little tail actually has these 3 functions you certainly don't ·High-heeled shoes audio sound? 4 coups to ease you learn a few ·How to choose shoes during pregnancy?
