Embodiment 1

[0043] A kind of preparation technology of softener film, described preparation technology comprises following preparation steps:

[0044] 1) Acylation reaction: put the hydrogenated oil in a container, then add industrial stearic acid into the container for preheating with hot steam at 85°C, preheat until the industrial stearic acid dissolves and then pump diethylenetriamine to Heat the steam to 125°C and keep it warm for 150 minutes. During the heat preservation reaction, the steam is collected by a condensing device at the same time, and intermediate I is obtained after the reaction;

[0045] 2) Quaternization reaction: Cool the intermediate I after step 1) to 75°C, and add epichlorohydrin dropwise to intermediate I within 1.5 hours in a uniform dropwise manner, and the dropwise addition is completed Then heat up to 125°C with hot steam, then carry out a second heat preservation reaction for 200 minutes, and then cool down to 75°C after the completion of the reaction to obt...

Embodiment 2

[0049] A kind of preparation technology of softener film, described preparation technology comprises following preparation steps:

[0050] 1) Acylation reaction: put the hydrogenated oil in a container, then add industrial stearic acid into the container for preheating with hot steam at 95°C, preheat until the industrial stearic acid dissolves and then pump diethylenetriamine to Heat the steam to 140°C and keep it warm for 105 minutes. During the keep warm reaction, the steam is collected by a condensing device at the same time, and intermediate I is obtained after the reaction;

[0051] 2) Quaternization reaction: Cool the intermediate I after the reaction in step 1) to 85°C, and add epichlorohydrin dropwise to intermediate I within 2 hours by dropping at a constant speed. Heat up to 140°C with hot steam, then carry out a second heat preservation reaction for 150 minutes, after the reaction is completed, cool down to 85°C to obtain intermediate II;

[0052] 3) Slicing: Slowl...

Embodiment 3

[0055] A kind of preparation technology of softener film, described preparation technology comprises following preparation steps:

[0056] 1) Acylation reaction: put the hydrogenated oil in a container, then add industrial stearic acid into the container for preheating with hot steam at 90°C, preheat until the industrial stearic acid dissolves and then pump diethylenetriamine to Heat the steam to 130°C and keep it warm for 120 minutes. During the heat preservation reaction, the steam is collected by a condensing device at the same time. After the reaction, intermediate I is obtained;

[0057] 2) Quaternization reaction: Cool the intermediate I after step 1) to 80°C, and add epichlorohydrin dropwise to intermediate I within 2 hours in a uniform dropwise manner. Heat up to 130°C with hot steam, then carry out a second heat preservation reaction for 180 minutes, after the reaction is completed, cool down to 80°C to obtain intermediate II;

[0058] 3) Slicing: Slowly add glacial ...

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...
