Problems solved by technology

The early silicone fabric finishing agents were mainly mechanical mixtures of dimethyl silicone oil and hydrogen-containing silicone oil. Due to the lack of active groups, this silicone has poor bonding fastness to the fabric and is easy to fall off, and the treated fabric feels relatively soft. Difference
Subsequently, soft and smooth finishing agents with high-viscosity hydroxyl silicone oil as the main component appeared, but the application effect of this kind of finishing agent is general, and there are disadvantages such as poor emulsion stability, easy delamination, and easy demulsification, etc., which have high requirements for the use environment. Oil drifts easily and can cause damage to textiles
In recent years, there are many fabric softening and smoothing agents based on amino silicone oil that have been sold on the market. Although they have achieved a good softening effect, their smoothness is not enough.

Abstract

The invention discloses an organic fluosilicic multifunctional textile finishing agent. Aiming at the problem existing in the current commercially available organic silicone finishing agent, a small amount of organic fluorin radical is introduced to the organic silicone finishing agent; under the condition of not changing the original effect of the organic silicone finishing agent, the smooth property of the finishing agent is further improved, simultaneously, water-and-oil-repellent effect is increased to a certain extent; the finishing agent is innocuous and pollution-free, and has high cost performance and wide application prospect. The invention also discloses a preparation method of the organic fluosilicic multifunctional textile finishing agent which has simple technological operation, the prepared latex has strong stability and difficult emulsion breaking, delamination does not happen after the latex is placed for a long time, the use is simple, the hand-feeling of the textile is obviously improved and the additional value is increased.

Description

technical field [0001] The invention relates to a fabric finishing agent, in particular to an organosilicon-fluorine multifunctional fabric finishing agent and a preparation method thereof. Background technique [0002] Silicone emulsion is an important finishing agent in the post-treatment process of fabrics. It can significantly improve the hand feel of fabrics, making them smooth, soft and plump. Early silicone fabric finishing agents were mainly mechanical mixtures of dimethyl silicone oil and hydrogen-containing silicone oil. Due to the lack of active groups, this silicone has poor bonding fastness to fabrics and is easy to fall off, and the treated fabric feels relatively soft. Difference. Subsequently, soft and smooth finishing agents with high-viscosity hydroxyl silicone oil as the main component appeared, but the application effect of this kind of finishing agent is average, and there are disadvantages such as poor emulsion stability, easy delamination, and easy de...
