1. The slurry sizing process and the high speed movement of the yarn cause many foams to appear.
2. In the pre-treatment process, when the desizing agent is used in the desizing of the product, and the bleaching and washing agent is used as the bleaching agent and the cleaning agent, in order to penetrate the fabric better and more uniformly, the high-temperature scouring is used to cause the foam to be generated.
3. During normal temperature dyeing and high temperature dyeing, mechanical vibration causes foaming.
4. The pulping process and the colorant produce foam during the mixing process of the printing process.
