Abstract

The invention discloses an amino-silicone oil softener containing a fluorine group and a quaternary ammonium salt group as well as a preparation method and application thereof. The method comprises the following steps: mixing a linear body with a silane coupling agent having amino and a silane coupling agent having a fluorine group when in preparation to react for 1-24h at the temperature of 30-120 DEG C, thereby preparing preparing amino-silicone oil containing the fluorine group; then carrying out quaternarization on amino-silicone oil containing fluorine for 2-10 hours at the reaction temperature of 50-120 DEG C by using a quaternizing agent in isopropanol or ethanol; and distilling at reduced pressure to remove a solvent and a low-boiling-point substance from the quaternary ammonium reaction product, so as to prepare the amino-silicone oil softener containing the fluorine group and the quaternary ammonium salt group. The baffeta finished by the softener prepared by the preparation method has excellent limpness, good antibacterial property, good water repellency, low yellowing property and water resistance. A finishing agent endowing a plurality of properties on fabric is achieved; the problems of compound and compatibility caused by use of a plurality of finishing agents are avoided and the finishing process is simple.

Description

technical field [0001] The invention relates to an amino silicone oil softener, in particular to a preparation method and application of an amino silicone oil softener containing fluorine groups and quaternary ammonium salt groups. Background technique [0002] Amino silicone oil is known as the new generation of best silicone softener. Because the polarity of the amino group is strong, it can interact with the hydroxyl group, carboxyl group and other groups in the fiber, resulting in strong orientation and adsorption, so that the siloxane is oriented on the fiber, that is, the siloxane on the fiber surface Good film-forming property, which endows the treated fabric with softness, smoothness and good hand feeling. In addition, during finishing and baking, at high temperature, the polar groups in the amino silicone oil can interact with the polar groups in the fibers to form covalent bonds, making the treated fabrics have better washability. [0003] But along with the rais...
