Dye Concentration (owf% ↔ g/L)Textile Manufacturing
Convert between on weight of fiber (% owf) and concentration in grams per liter (g/L) based on custom liquor bath parameters.
Liquor ratio represents the amount of water compared to fabric weight. Standard commercial dyeing typically operates at compact 1:8 to 1:15 liquor ratios.
*Auxiliary calculations are standardized estimates for reactive cotton dyestuffs. Adjustments may be required depending on dyestuff manufacturer, specific liquor temperature, and salt varieties.
