Problems solved by technology

[0004] Among the softeners in the prior art, the content of ammonia that has a deep impact on the softening effect, when the ammonia content is low, the softening effect is relatively poor, which is not conducive to the softening of the fabric. At the same time, when the ammonia content is large, It is also prone to yellowing. For this reason, in the prior art, people have thought of carrying out silicone oil modification and the change of the catalyst. If the above-mentioned changes are not very effective, there are obstacles in actual production. For this reason, it is necessary to develop a A new type of textile softener and its preparation method, so that the ammonia content can meet the requirements of mass production

Embodiment 1

[0027] Use a vacuum pump to pump 156 parts of DMC (dimethyl siloxane mixed ring) into the reactor and stir to raise the temperature. Slowly add 4 parts of 602 aminosilane and 20 parts of DMSO (dimethyl sulfoxide) for preliminary pre-dissolution with stirring. Finally, add 0.3 parts of 5% KOH solution and 0.2 parts of distilled water, and feed N2 at the bottom of the reactor;

[0028] Heat the reaction kettle to 70°C, stop filling N2, and start the vacuum pump, keep the vacuum at 0.09Mpa, continue to heat up until the temperature in the reaction kettle rises to 90°C, maintain the reaction for 10 minutes, then raise the vacuum to 0.096 Mpa, and continue to maintain the reaction After 50-60 minutes, observe the viscosity of the reactants in the reactor, which is like (1000CS-2000CS) methyl oil;

[0029] When the viscosity reaches the above-mentioned methyl oil, flush N2 from the top of the kettle, fill the vacuum gauge back to its original position, start stirring, keep the tempe...

Embodiment 2

[0037] Use a vacuum pump to pump 190 parts of DMC (dimethylsiloxane mixed ring) into the reactor and stir to raise the temperature. Slowly add 8 parts of 602 aminosilane, 40 parts of DMSO (dimethyl sulfoxide), and 50 cs of dimethyl silicone oil. 40 parts, 10 parts of MM (hexamethyldisiloxane), after preliminary pre-dissolving with stirring, add 5% KOH to make 0.8 parts of the solution, and feed N2 at the bottom of the reaction kettle;

[0038] Heat the reaction kettle to 70°C, stop filling N2, and start the vacuum pump, keep the vacuum at 0.09Mpa, continue to heat up until the temperature in the reaction kettle rises to 90°C, maintain the reaction for 10 minutes, then raise the vacuum to 0.096 Mpa, and continue to maintain the reaction After 50-60 minutes, observe the viscosity of the reactants in the reactor, which is like (1000CS-2000CS) methyl oil;

[0039] When the viscosity reaches the above-mentioned methyl oil, flush N2 from the top of the kettle, fill the vacuum gauge ...

Abstract

The invention provides a novel textile softener and a preparation method thereof. The novel textile softener is prepared from the following raw materials in parts by mass: 20 parts of amino silicon oil, 4 to 6 parts of AEO-3 (carbon 12-13 fatty alcohol polyoxyethylene ether), 4 to 6 parts of TX-10 (alkylphenol ethoxylates), 0.3 to 0.6 part of glacial acetic acid and 70 parts of deionized water. The softener prepared by the method and the raw materials has the characteristics that the softener is suitable for large-scale production and the ammonia value content meets the use requirements.

Description

technical field [0001] The invention relates to a softener preparation technology. 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. [0003] Soft finishing is an important finishing process in printing and dyeing processing. During the processing of textiles, the handle will become rough after repeated treatments, and the synthetic fiber fabrics are generally worse, especially the microfiber fabrics. In order to make the fabric have a soft, smooth and comfortable feel, it needs to be finished. At present, it is widely used to finish with a softener. In addi...
