Abstract:

Silicone oil softener plays an important role in the treatment of textiles, but with the improvement of the quality requirements for textiles, the general silicone oil softener has been unable to meet the demand. Under this background, the dilution stability of amino modified silicone oil softener was studied. The basic silicone oil compound was prepared and modified with amino acid containing amino acid. The delamination test, surface tension test and water permeability test were carried out under dilution multiple for amino modified silicone oil softener. The results show that under the centrifugal stability, acid resistance stability and alkali resistance stability tests, the solution does not show delamination. While the thermal stability and electrolyte resistance stability test items show delamination, the proportion coefficient is below 0.1, indicating that the amino modified silicone oil softener maintains good stability after dilution. With the increase of dilution ratio, the surface tension of amino modified silicone oil softener becomes smaller and smaller, and the light transmittance becomes larger and larger. With the extension of time, although both of them are fluctuating, they ultimately remain at a certain level, proving the stability of their performance.
