Problems solved by technology

However, it still uses amino silicone oil, which will inevitably cause yellowing, and the dispersion uniformity of the added nano-diatomaceous earth is not good, and oil floating or sticking to the roller will still occur.

Embodiment 1

[0033] Embodiment 1 provides a kind of preparation method of fabric softening finishing agent, is characterized in that, comprises the steps:

[0034] Step S1, epoxy-modified bis(2-hydroxyethyl)amino(trimethylol)methane: adding bis(2-hydroxyethyl)amino(trimethylol)methane and epichlorohydrin to the organic solvent , stirred and reacted at 30°C for 4 hours, and then the solvent was removed by rotary evaporation to obtain an intermediate product;

[0035] Step S2, preparation of modified amino silicone oil: add amino silicone oil, the intermediate product prepared through step S1, and the basic catalyst to isopropanol, reflux and stir at 70°C for 3 hours, and then spin evaporate to remove isopropanol , and adding water therein, separating the liquids, taking the oil phase, and removing the water by rotary evaporation to obtain the modified amino silicone oil;

[0036] Step S3, ion exchange: add the modified amino silicone oil and polyoxyethylene lauryl ether carboxylic acid pre...

Abstract

The invention discloses a preparation method of a fabric softening finishing agent. The preparation method is characterized by comprising the following steps of S1, carrying out epoxy modification onbis(2-hydroxyethyl) amino (trihydroxymethyl)methane; S2, preparing modified amino silicon oil; S3, carrying out ion exchange; and S4, preparing the softening agent. The invention further provides thefabric softening finishing agent prepared according to the preparation method of the fabric softening finishing agent. The fabric softening finishing agent disclosed by the invention is good in softening finishing effect and good in performance stability, so that a finished fabric has more comfortable sensation and hand feeling, and a relatively high finishing effect can be achieved with a relatively small mixing amount.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing auxiliaries, in particular to a fabric softening and finishing agent and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, more and more people begin to pursue the quality of life. "A person depends on clothes and a horse depends on a saddle". Clothing fabrics put forward higher requirements, such as the ability to maintain the texture of clothing fabrics during wearing and use, and to have a soft, smooth, and elegant style for a long time. To achieve this goal, soft finishing is essential. [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 soft, smooth and comfortable, it needs...
