Textile processing is an essential part of the textile manufacturing process. Majorly, it involves processing the textile through Pretreatment, Dyeing, and Finishing phases, sequentially. Pretreatment prepares the textile for the dyeing process, whereas dyeing involves using dyes and auxiliaries to provide the fabric with colors, patterns and color fastness. Finishing is the last step of
Read MoreWhat is Foam? Foam is a coarse dispersion of a gas in a liquid, where the volume fraction of gas is greater than that of the liquid. The bubbles will migrate to the surface, as their density is less than that of the liquid. As the bubbles coalesce and collect at the air/surface interface, the
Read MoreFoam in the Pulp & Paper Industry Lignin, rosin and fatty acid soaps, and hemicelluloses are commonly formed during the pulping process, resulting in high levels of foam. Excess foam will negatively impact process and equipment efficiency, leading to inferior or rejected paper. Defoamers and antifoams are a necessity to the entire paper making process.

What is flocculation? Flocculation is the separation of a solution, commonly the removal of sediment from a fluid. The term is derived from floc, which means flakes of material; and when a solution has been flocculated, the sediment has formed into larger aggregated flakes, making them easier to see and remove. This process occurs naturally,
