Textile printing and dyeing defoamer use problem list
Jul 05, 2024
As we all know, in the textile printing and dyeing process foaming is difficult to avoid a problem, so most of the textile printing and dyeing manufacturers in the production of textiles will be used to textile printing and dyeing defoamer. However, many manufacturers in the use of defoamer more or less will appear some problems, these problems have been plagued by various manufacturers, I found through the collection of the following problems are common. 1. After adding antifoam agent will produce a white silicon spot on the fabric and other residues; 2. Defoamer defoaming, foam inhibition effect is not ideal; 3. In high temperature, strong acid and alkali, defoamer defoaming effect is not obvious; 4. Defoamer can only short time defoaming, can not be a long time to inhibit foam.
These are the textile printing and dyeing manufacturers in the use of defoamer in the process of the problem. Through the study of these problems, defoamer manufacturers have also given the corresponding solutions. 1. Defoamer additives should not be too much or too little, too much additives will lead to part of the defoamer can not be dissolved, deposited in the raw material, there is a white silicon spot and other residues, additives are too little, the effect of defoaming will be unsatisfactory; 2. When stirring the defoamer, the stirring speed should not be too fast and the time should not be too long; 3. Different defoamers have different temperature range, before use should read the manual, keep in mind the precautions, so as not to destroy the stability of the defoamer; 4. Water will destroy the stability of the defoamer, so pay attention to the amount of water added in the dilution, to avoid the nature of the defoamer is affected; 5. Antifoaming agent whether expired will also affect the antifoaming agent defoaming, foam inhibition performance;
