Calculate material correctly

Guide — at the end you know the suitable material for your product, the material length per bobbin as well as product length and product weight

Prerequisites:

  • The materials are recorded with Density and Titer in the material master data — the material selection lists of the calculations are filled from there and apply density and fineness automatically.
  • The bobbin formats are maintained with their dimensions.
  • You know the common structure of the calculation pages — see How calculation pages are structured.

The steps build on each other — but you can also use just a single calculation from the chain at any time. You can reach all calculators via the tile overview Calculations or via the navigation bar on the left.

Step 1: Maintain material master data

Under Master data > Materials, check whether the material has been created with name, density and titer; if not, create it via New material (reference: Materials). The maintenance effort pays off: in all subsequent calculations, simply selecting the material from the selection list is then sufficient.

Step 2: Determine and convert the fineness

  • With the calculation Fineness you determine which yarn count is required for the desired braid.
  • If supplier specifications are in a different unit (tex, dtex, den, Nm, Ne), use the live converter Fineness conversion.

Step 3: Determine material diameter and ply count

Depending on what you know:

  • You know the material (fineness, density) and want to know its diameter → Material diameter from material.
  • You know the finished product (diameter, number of carriers, braiding angle) and are looking for the suitable yarn → Material diameter from product — this calculation additionally suggests a suitable material from your material database.
  • You want to know how many threads per carrier the selected material must be used with → Ply count from product.

Step 4: Calculate the material length on the bobbin

Step 5: Calculate product length and product weight

Result

  • You have a continuous calculation chain from raw material to the finished product.
  • Every completed calculation is stored in the History and can be reloaded from there with the inputs used at the time.
  • You can output the results via print templates and use them in the braiding order — many of these calculations are linked directly at the fields there.
