Warping is a crucial step in textile processing, involving dyeing, finishing, printing, and other aspects. To ensure accuracy and efficiency in warping, using calculation formulas is essential. This article introduces several common warping calculation formulas and provides a step-by-step guide to the warping process.

Total number of roots calculation

Basic formula

Parameter Description:

Warp Density: Number of warp yarns per 10 cm of fabric (unit: yarns/10cm)

Fabric Width: Width of the finished fabric (unit: cm)

Side Yarn Count: Number of warp yarns along both edges of the fabric; usually added symmetrically.

Correction Formula (considering reed weaving differences)

Corrected scenario: When the weaving methods for the ground warp and edge warp are different (e.g., 2 threads per reed for the ground warp, 4 threads per reed for the edge warp)

Note: If in inches, a rough calculation can be used: Total warp threads = Warp density * Fabric width

For example: Rough calculation of total warp threads: 130 * 63 = 8190 threads
