Calculating thread consumption is a important part of cost calculation and garment manufacturing. In our earlier post we have written about garment sewing thread calculation. Second impartment area is embroidery thread calculation which we will review here. Embroidery thread calculation depends of some parameters like stitch type, thread type, no of colors, no of stitches in design.
Generally Embroidery machines work with stitch type 301, the lock-stitch. With the optimal adjustments of all the parameters it should amount to a shared proportion of 2/3 needle thread and 1/3 bobbin thread. On average the thread usage can be calculated as seen below
per 1.000 stitches needle thread 4,6 m bobbin thread 2,3 m
Example of Embroidery Thread Calculation :-
Number of Pcs – 4,000 pcs
Stitch qty in the embroidery design – 4,500 (stitch) ( how to estimate the stitch amount of an embroidery design?)
Length of thread in the cones – 5,000 meter
Stitch length – 4 mm (stitch length depends on design and stitch type)
= Number of Garments qty X Number of stitch X 4 / 1000 / meter per cone.
= 4,000 X 4,500 X 4 / 1,000 / 5,000
= 18,000,000 X 4 / 1,000 / 5,000
= 72,000,000 / 1,000 / 5,000
= 72,000 / 5,000
