Abstract :In this study, silicone finishing chemicals were produced using organo-modified, amino-functional silicone oils and polar additives (polyethyleneglycol). Silicone emulsions are affected by many factors. These are the type of oil used when producing silicone softener emulsions, the ratio of emulsifiers, hydrophile-lipophile balance ( HLB) values of emulsifiers, particle size of the silicone finishing chemicals produced, and viscosity of silicone emulsions. After the application, quantitative handle, soft feel, particle size analyzes of the prepared silicone finishing chemicals, CIELab color, and Berger whiteness index measurements were evaluated. As a result, organo-modified and amino-functional silicone finishing chemicals caused the handle, softness properties, and color differences in cotton knitted fabrics. The large particle size of emulsions caused the large color difference, which is calculated from the changes in color coordinates. The main factor affecting the softening (quantitative behavior) of fabric samples applied with silicone finishing chemicals is the number of amino groups. At pH 5.5, the better handle and softness properties were obtained as more secondary amine groups were ionized. The particle size and viscosity of silicone finishing chemicals have an effect on the handle of fabric samples.
