Textiles sizing agents/chemicals are water soluble polymers that are used to protect yarn in the yarn sizing process. Such agents are modified starch, polyvinyl alcohol (PVA), carboxymethyl cellulose (CMC) and acrylates.
Before yarn can be woven, it needs to be strengthened to withstand the stress sustained in weaving on a high-speed industrial looms. For this purpose, the yarn is passed through a sizing bath that contains the sizing medium, mixed with water and other additives depending on the formula.
In-line Vaisala K-PATENTS® process refractometer monitors the concentration of the sizing bath as it may fluctuate due to the evaporation and yarn absorption.
The refractometer is also used to measure concentration in the product tanks, or during sizing medium mixing to ensure correct concentration levels.
