How to Use This Calculator
  1. Enter Fiber Type, Cotton, and Polyester.
  2. Set Nylon, Wool, and Silk.
  3. Adjust Weave Structure, Plain Weave as needed.
  4. Review the Strip Tensile (1 in) (N) result.
  5. Use Yarn Break Strength (cN) and Full Width Tensile (lbf) to inform your decision.

What each input means

Fiber Type
Primary fiber in the fabric
Weave Structure
Weave type affects interlacing efficiency
Yarn Count
Yarn linear density in tex (g/1000m)
Threads per Inch
Thread density in the test direction
Fabric Width
Full fabric width for total breaking strength

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Fiber Type = 0, Weave Structure = 0, Yarn Count = 30, Threads per Inch = 80 = 5 input(s) provided
  2. Calculate Strip Tensile
    Strip Tensile
    510 = 510
  3. Calculate Yarn Break Strength
    Yarn Break Strength
    750 = 750
  4. Calculate Full Width Tensile
    Full Width Tensile
    6877 = 6877
