How to Calculate Thread Consumption for Garments?

Image
There is a standard formula for determining thread consumption for apparel products. In that formula, you will get multiplying factors according to machine type and stitch class. To determine thread consumption you just need to multiply seam length with those factors. This way one can estimate the total thread requirement for making a garment. Actual thread consumption for a unit length of seam depends on the following factors.  Stitch Classes Stitches per inches (SPI) The thickness of the seam (fabric thickness) Thread tension   Thread count (thickness of sewing thread) So you are suggested to calculate garment thread consumption by your own. You can develop a multiplying factor according to your product categories and requirement using the following steps. Step 1:  To calculate thread ratio, you need a sewing machine, fabric and sewing thread that will be used for bulk production. For fabric and thread, you can take similar thickness and same thread count in ca

Stitch: Stitch is very important during  manufacturing a garment . Stitch can be defined as, one unit of conformation resulting from one or more strands or loops of thread by intra-looping, inter-looping and interlacing. Stitch quality is measured with stitch size, stitch length, width, depth, tension, sequence, elongation, elasticity, resilience, fabric distortion, yarn severance and abrasive strength. There are six types of stitch, which are deeply discussed in this article. Types of Stitch Used in Garments: There are different types of stitch used in garments; those are mentioned in the following: 1.     Class-100 (Chain Stitch), 2.     Class-200 (Hand Stitch), 3.     Class-300 (Lock Stitch), 4.     Class-400 (Multi Thread Stitch), 5.     Class-500 (Over Edge Stitch), 6.     Class-600 (Covering Chain Stitch). All the above types of stitch have discussed in the below: 1. Class-100 (Chain Stitch): Class-100 named as chain stitch, which is produced by one
