Problems solved by technology

[0004] The technical problem to be solved in the present invention is: to solve the problem that the existing spice capsules are used as fragrance microcapsules in the fragrance processing of textiles, because the particles are too large, and the mesh holes are easily blocked during printing; Fabrics or other solid surfaces are not only easy to rub and slip off but also easy to wash

Example Embodiment

[0028] Example 1

[0029] Preparation of lavender spice nanocapsule dispersion:

[0030] 50 parts of lavender essence, 15 parts of dispersing emulsifier, and 300 parts of distilled water are homogenized at high speed in a high-shear mixing emulsifier at a homogenization rate of 10000rpm. After 30 minutes, adjust the pH to 2.5-3.5 with acetic acid, and then homogenize Pour the emulsion into a three-necked flask and put it in a constant temperature water bath. Under stirring conditions, at a stirring speed of 300 rpm, add 80 parts of etherified melamine resin dropwise, heat up to 60 ℃, and keep it for 2 hours to make a single-layer wall; After the system was cooled to room temperature, 80 parts of etherified melamine resin was added dropwise again under stirring conditions, the temperature was raised to 70° C., the temperature was kept, and the second wall building was performed. Cool and neutralize to pH=7 to obtain lavender nanocapsule dispersion. The electron micrograph of the ob...

[0031] Example 2

[0032] Fragrance finishing of colored cotton knitted fabrics:

[0033] Process: Adopt padding method: padding (two dips and two rollings, carrying liquid volume 70%)→drying (90-100℃)

[0034] Padding liquid prescription:

[0035] Lavender flavor nanocapsule dispersion 50g / L

[0036] Formaldehyde-free super soft adhesive 30g / L

[0037] The color of the colored cotton fabric before and after the fragrance finishing is basically the same, and the hand feel has little change. The formaldehyde content is 5.3mg / kg. After the colored cotton knitted fabric is washed for 20 times, the content of fragrance in the fabric only decreases by about 29%. The fabric treated with perfume nanocapsules is stored in the open. As the storage time is extended, the flavor content on the fabric continues to decrease, as shown in Figure 2. By 6 months, 450mg / Kg of flavor still remains in the fabric capsule , The fabric exudes a pleasant fragrance.

[0038] Example 3

[0039] Preparation of Baiai Shen flavor nano-capsule dispersion:

[0040] 30 parts of Baiai Shen essence, 10 parts of anionic dispersant, 5 parts of non-ionic emulsifier, and 300 parts of distilled water are homogenized in a high-shear mixer emulsifier at high speed. The homogenization rate is 10000rpm. After 30 minutes, adjust with acetic acid The pH is 3-4, then pour the homogenized emulsion into a three-necked flask and put it in a constant temperature water bath. Under stirring conditions, at a stirring speed of 300 rpm, add 80 parts of etherified melamine resin dropwise and heat up to 56°C After the system is cooled to room temperature, 80 parts of etherified melamine resin are added dropwise again under stirring conditions, the temperature is raised to 70°C, the temperature is kept, and the second wall is made. Cool and neutralize to pH=7 to obtain Baiaishen essence nanocapsule dispersion.

Abstract

The present invention relates to fine chemical technology, and is especially preparation process and application of nanometer perfume capsule dispersing liquid. Etherified melamine resin prepolymer is used as the monomer for forming capsule wall material and is in-situ polymerized to prepare nanometer perfume capsule dispersing liquid. The said process can prepare capsule with concentrated particle size, average particle size of 140-180 nm, excellent dispersivity and excellent slow releasing property, and the capsule may be used in the scenting finishing of fabrics as well as ink, paint, printed matter, etc.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals, and in particular relates to a preparation method and application of a spice nanocapsule dispersion. Background technique [0002] Capsules are classified according to particle size: large capsules, with a particle size greater than 1,000 μm; microcapsules, with a particle size in the range of 1 to 1,000 μm; and nanocapsules, with a particle size of less than 1 μm. In the 21st century, people are aware of the efficacy of microcapsule finishing, especially in developed countries, such as Japan, the United States and some European countries. The rapid development of microcapsule technology has led to technological innovation in textiles in terms of functionality, fashion, and advancement. Fragrance It can not only make people have beautiful reverie, but also has many health care effects. Scientific research has proved that many aromatics have the effects of calming, sterilizing, and health ...
