Abstract

The invention discloses a super-hydrophilic low-yellowing organic silicon softening agent and a preparation method thereof. The preparation method is characterized by including the steps: adding polysiloxane containing alkoxy, ether and quaternary ammonium and emulsifying agents into an emulsifying kettle; stirring mixture for 5-30 min; adding acetic acid to adjust a pH (potential of hydrogen) value to be 5-6; adding glycerin and deionized water to continue to stir mixture for 10-40min to prepare the super-hydrophilic low-yellowing organic silicon softening agent. The prepared organic siliconsoftening agent is good in hydrophilic property, low in yellowing, good in stability, washable and smooth and can reach instant hydrophilic effects (lower than 1s), and yellowing rate is smaller than0.4%. The preparation method is simple, convenient and easy and low in production device requirement, and industrial production is easily achieved.

Description

technical field [0001] The invention relates to the technical field of textile finishing agents, in particular to a super-hydrophilic low-yellowing silicone softener and a preparation method thereof. Background technique [0002] Softening the fabric can reduce the frictional resistance between the fabric fibers and between the fibers and the skin, so that the fabric has a soft, smooth, delicate feel, and is comfortable and beautiful to wear. Softener is a functional chemical additive that can improve the touch of fabric fiber products. Amino silicone oil has good softness, smoothness and film-forming properties, so it is called a super softener, and it is a type of silicone softener that is currently used in a large amount on the market. Although the flexibility and washability of amino silicone oil are outstanding, there are also obvious disadvantages. One is that there is no hydrophilic group in the molecular structure of amino silicone oil, and the finished fabric is n...
