Problems solved by technology

The amino silicone oil and the quaternized modified amino silicone oil emulsion were softened and finished on pure cotton fabrics, and the whiteness, breaking strength, tearing strength, hydrophilicity and bending of the fabric in the fabric style test were measured and compared. , shear, compression properties and surface friction properties. The results show that the yellowing phenomenon of the fabric after the modified amino silicone oil emulsion is significantly reduced, the hydrophilicity is greatly improved, and the good hand feeling of the fabric is maintained, and the elasticity and compression properties are also improved. Aspect is obviously better than unmodified amino silicone oil, it is the closest prior art of the present invention, but the preparation process of this technology is complicated, and the impact on the hydrophilicity whiteness of the fabric after finishing is still not ideal, and it is not ideal for affecting the over-dyeing of the fabric. and color correction have certain adverse effects

Abstract

The invention discloses a preparation method and application of a quaternization modified amino silicon oil softener. The preparation method comprises the following steps: I, adding trifluoroacetic acid into epoxy chloropropane, stirring, and sealing for reaction so as to obtain an upper-layer transparent solution; II, dissolving amino silicon oil into a propyl acetate solution, gradually dropping the upper-layer transparent solution prepared in the step I, stirring, and heating for reaction, thereby obtaining the quaternization modified amino silicon oil softener. The quaternization modified amino silicon oil softener prepared by using the preparation method can be applied to the softness finishing process of pure cotton textile. The invention further discloses a finishing process and belongs to the technical field of the spinning chemical industry. The preparation method disclosed by the invention is simple and convenient and easy to operate, the raw materials are green and environmentally friendly, the process is green, low in energy consumption and low in pollution, the pure cotton textile treated by using the prepared quaternization modified amino silicon oil softener is good in softness, the whiteness and the hydrophilia of the pure cotton textile are slightly affected, moreover later finishing processes of the pure cotton textile are also slightly affected, and thus relatively high market popularization values can be achieved.

Description

Technical field: [0001] The invention discloses a preparation method and application of a quaternized modified amino silicone oil softener, belonging to the technical field of textile chemicals. Background technique: [0002] There are many methods for the synthesis of organosilicon quaternary ammonium salts, among which the addition reaction of epoxy silane and tertiary amine, the substitution reaction of halohydrocarbyl silane and tertiary amine, the quaternization reaction of aminosilane and the reaction of aminosilane Ring-opening reaction with epoxy compounds. Regarding the quaternization modification of amino silicone oil, domestic and foreign studies have shown that: select different quaternization reagents to react with amino groups in amino silicone oil (silane) to obtain silicone oils containing different quaternary ammonium groups. The synthesis method of its quaternary ammonium salt modified amino silicone oil mainly has the following directions: [0003] React...
