The cause of silicone oil spots is a very complicated problem.

1. Silicone oil is not compatible with emulsifier. Silicone oil emulsion is unstable and easy to break emulsion.
2 The emulsion is in poor working condition, and the dye, alkali, inorganic and organic impurities on the fabric may cause the silicone oil to break the emulsion.
3 silicone oil emulsion is too sensitive to temperature, it may break the oil at a slight temperature (above 60 ° C).
4 Silicone oil is the easiest to break under alkaline conditions. Therefore, it is not possible to adjust the pH to alkaline in the emulsion, and adjust the pH to 5-6 during use.
5. Never add silicone oil under high temperature conditions. (Ordinary amino silicone oil: emulsifier quickly exceeds cloud point demulsification at high temperatures
6. Other impurities on the cloth surface: residue of anion auxiliaries and dyes.
7. The cylinder is not clean. If you do not wash the cylinder for a long time, it will cause silicon spots to be stained on the cloth surface.
8. If the silicone oil emulsion is used in a large amount, it may cause silicon spots to be produced.
The factory is most afraid of silicone oil spots when using silicone oil. If the generated silicone oil spots are more difficult to remove after high temperature setting. There are special additives for removing silicone oil spots on the market, which can be processed by high temperature soaking or padding. If the slight silicone oil spots are not dried or set at a high temperature, they can also be washed with glacial acetic acid.
 How to remove silicone oil can not treat silicone oil as a general oil contamination. The theory of silicone oil removal is to re-emulsifie it.
1 The scouring of woven cloth is a special scouring agent for silicone oil, which has special emulsification for silicone oil.
2 softener defoamer in the bath for dyeing, of course, should use high temperature resistance, if unfortunately poor, and residual in the dyeing cylinder wall is usually used to better the washing agent. These washing agents all contain the effect of emulsified silicone oil; if unfortunate If the cylinder wall is stuck, use a good washing agent or fluorinated hydrocarbon, tetrachloroethylene oxime solvent
3 finished product type waterproofing agent, of course, choose a good waterproofing agent and softener, unfortunately the wrong choice, oily silicone oil is full of rolls or cloth rolls, use a good bath or fluorinated hydrocarbon, tetrachloroethylene oxime solvent Wipe, but in order to prevent the rubber that may damage the roll, try to wipe it in a special part. After 30 minutes, see if there is swelling or damage, or use our silicone oil remover.
