(2) The mixing of air in the alkaline tank process liquid can also cause foam to be generated above the liquid level of the alkaline tank process, so that a large amount of foam exists in the overflow process liquid, and the foam exists in the process liquid fed into the process liquid alkaline concentration detection unit, so that the detection result of the alkaline concentration is inaccurate;
(3) The residual auxiliary agent, oil stain and water of the fabrics in the previous working procedure enter the alkaline tank process liquid to easily generate chemical reaction, so that foam is generated above the alkaline tank process liquid level, and a large amount of foam exists in the overflowed process liquid, so that the foam in the process liquid fed into the process liquid alkaline concentration detection unit causes inaccurate alkaline concentration detection result;
(4) When the rotary pump arranged on the process liquid sampling pipe is used for conveying the process liquid into the process liquid alkali concentration detection unit, a large amount of foam is generated by the process liquid under the rotation action of the impeller of the rotary pump, so that a large amount of foam exists in the process liquid conveyed into the process liquid alkali concentration detection unit, and the alkali concentration detection result is inaccurate.
