1. What is Thread Consumption Calculation?

The thread consumption calculation estimates the amount of thread needed for sewing fabric based on seam length and consumption factor. It helps in planning thread requirements for garment production.

2. How Does the Calculator Work?

The calculator uses the thread consumption formula:

Where:

• \( \text{Seam Length} \) — Length of the seam to be sewn (in meters)
• \( \text{Consumption Factor} \) — Thread usage factor (typically 2.5 to 7)

Explanation: The consumption factor accounts for thread used in stitches, loops, and tension. Different stitch types have different factors.

3. Importance of Thread Calculation

Details: Accurate thread calculation prevents shortages during production, helps in cost estimation, and reduces material waste in garment manufacturing.

4. Using the Calculator

Tips: Measure the seam length accurately. Select appropriate consumption factor based on stitch type (2.5 for simple seams, up to 7 for complex stitches).

5. Frequently Asked Questions (FAQ)

Q1: What affects the consumption factor?
A: Stitch type (lockstitch, chainstitch), seam type, fabric thickness, and thread tension all affect the factor.

Q2: How to measure seam length?
A: Measure along the stitching line of the pattern pieces before sewing.

Q3: What's a typical consumption factor?
A: For lockstitch (301), 2.5-3.5; for overlock (504), 4-7; for coverstitch, 5-7.

Q4: Should I add extra thread?
A: Yes, add 10-15% extra for thread breaks, machine setup, and adjustments.

Q5: Does thread thickness matter?
A: The calculator estimates length. For weight calculation, consider thread thickness (Tex number).
