(1) Sizing process: water-emulsion silicone defoamer, such as: silicone polyether, the amount added in the sizing tank 0.2-0.25g/L (2) Chemical fiber oil agent: chemical fiber oil agent added 0.02-0.04% water emulsion type defoamer. Organic silicone oil should be included in the formula of chemical fiber oil. (3) Desizing refining: the selection of polyether silicone. (4) Bleaching: strong acid, silicone defoamer. (5) Dyeing: silicone emulsion defoamer. Jet dyeing is best to choose polyether silicone, high temperature defoaming, low temperature water soluble, non-staining fabric.
