[0042] Example 1

[0043] A preparation process of a softener film. The preparation process includes the following preparation steps:

[0044] 1) Acylation reaction: Put the hydrogenated oil in a container, and then add industrial stearic acid to the container for preheating with hot steam at 85°C. After preheating the industrial stearic acid to dissolve, pump diethylenetriamine into the container. The hot steam is heated to 125° C. and the temperature is kept for 150 min. During the temperature keeping reaction, the steam is collected by a condensing device. After the reaction, intermediate I is obtained;

[0045] 2) Quaternization reaction: After step 1), the intermediate I after the reaction is cooled to 75°C, and the epichlorohydrin is added dropwise to the intermediate I in 1.5h in a uniform dropwise manner, and the addition is complete After heating with hot steam to raise the temperature to 125°C, perform a second heat preservation reaction for 200 minutes, and after the reac...

Abstract

The invention relates to a weaving auxiliary agent, and especially relates to a softening agent film preparation technology. The preparation technology comprises the following steps: 1) an acylation reaction: placing an organic solvent in a container, adding industrial stearic acid in a container for preheating, and preheating the material until the industrial stearic acid is dissolved, adding diethylenetriamine, heating the material to the temperature of 125-140 DEG C and performing insulation for a reaction, during an insulation reaction process, collecting steam by a condensation apparatus,and obtaining an intermediate I after the reaction is completed; 2) a quaternization reaction: cooling the intermediate I after the reaction is completed in the step 1) to the temperature of 75-85 DEG C, dropping chloropropylene oxide, after dropping, heating the temperature to 125-140 DEG C, performing a secondary insulation reaction, and after the reaction is completed, cooling the material tothe temperature of 75-85 DEG C to obtain an intermediate II; and 3) slicing: slowly dropping glacial acetic acid in the intermediate II, adjusting a pH value to weak acid, and performing refrigerationand slicing to obtain the softening agent film.

Description

technical field [0001] The invention relates to a textile auxiliary agent, in particular to a preparation process of a softener film containing a quaternary ammonium group and having strong anti-yellowing ability and antibacterial ability. Background technique [0002] Softeners are a class of chemical substances that can change the static and dynamic friction coefficients of fibers. When the coefficient of static friction is changed, the hand feels smooth and easy to move on the fiber or fabric; when the coefficient of dynamic friction is changed, the fine structure between fibers is easy to move with each other, that is, the fiber or fabric is easy to deform. The combined feeling of the two is soft. There are four types of softeners according to their ionic properties: cationic, nonionic, anionic, and amphoteric quaternary ammonium salts. As a conventional finishing aid for fabrics, softener has been used for more than half a century and has developed very rapidly. It ha...
