Q What is the difference between antifoam and defoamer?

A
Defoamer vs anti-foam agent

The key difference between defoamer and anti-foam is that anti-foam agents can prevent foam from forming, whereas defoamers can control the amount of existing foam. Therefore, anti-foam agents prevent foam formation while defoamers reduce existing foam.
Q Is anti-foam a surfactant?

A
However, they achieve this goal in different ways; antifoams are surfactants that prevent foam from forming in the first place, while defoamers are surfactants that control existing foam levels by stopping the bubbles from stabilizing.
Q What is a good anti-foaming agent?

A
Commonly used antifoaming agents are certain alcohols (cetostearyl alcohol), insoluble oils (castor oil), stearates, polydimethylsiloxanes and other silicones derivatives, ether and glycols (Karakashev and Grozdanova, 2012).
Q What is anti-foaming agent in textile?

A
A defoamer or an anti-foaming agent is a chemical additive that reduces and hinders the formation of foam in industrial process liquids. The terms anti-foam agent and defoamer are often used interchangeably. Strictly speaking, defoamers eliminate existing foam and anti-foamers prevent the formation of further foam.
Q What are the causes of foaming in textile printing and dyeing?

A The sizing process and the high-speed movement of the yarn lead to foaming; in the pretreatment process, high-temperature scouring leads to foaming; in the process of medium-temperature dyeing and high-temperature dyeing, mechanical operation vibration leads to foaming; The paste generates foam during the stirring process in the printing process.
