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 off, and cannot achieve long-lasting fragrance and other technical problems. The fragrance nanocapsule prepared by the preparation method of the fragrance nanocapsule dispersion of the present invention is a spherical capsule. , containing essence, the average particle diameter is about 140-180nm, the capsule wall has thermosetting properties, strong, and good processing performance

Embodiment 1

[0029] Preparation of lavender spice nanocapsule dispersion:

[0030] Homogenize 50 parts of lavender essence, 15 parts of dispersing emulsifier, and 300 parts of distilled water in a high-shear mixing emulsifier at a high speed at a speed of 10,000 rpm. After 30 minutes, adjust the pH to 2.5 to 3.5 with acetic acid, and then homogenize The emulsion was poured into a three-necked flask and placed in a constant temperature water bath. Under stirring conditions and a stirring speed of 300rpm, 80 parts of etherified melamine resin was added dropwise, the temperature was raised to 60°C, and the temperature was kept for 2 hours to form a single-layer wall; After the system was cooled to room temperature, 80 parts of etherified melamine resin was added dropwise under stirring condition, the temperature was raised to 70°C, and the temperature was kept for the second wall building. Cool and neutralize to pH=7 to obtain a lavender nanocapsule dispersion. The resulting perfume nanocaps...

Embodiment 2

[0032] Scent finishing of colored cotton knitted fabrics:

[0033] Process: padding method: padding (two dipping and two rolling, liquid carrying capacity 70%) → drying (90-100°C)

[0034] Padding solution prescription:

[0035] Lavender essence nanocapsule dispersion 50g / L

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

[0037] The color of the colored cotton fabric before and after fragrance finishing is basically the same, and the hand feeling has little change. The formaldehyde content is 5.3mg / kg. After the colored cotton knitted fabric is washed 20 times, the fragrance content in the fabric only decreases by about 29%. The fabric treated with perfume nanocapsules is stored openly, and as the storage time prolongs, the essence content on the fabric decreases continuously, as shown in Figure 2, until 6 months, there is still 450mg / Kg of essence remaining in the fabric capsule , the fabric exudes a pleasant fragrance.

Embodiment 3

[0039] Preparation of Baiaishen essence nanocapsule dispersion:

[0040] Homogenize 30 parts of Baiaishen essence, 10 parts of anionic dispersant, 5 parts of nonionic emulsifier, and 300 parts of distilled water in a high-shear mixing emulsifier at a high speed. The homogenization rate is 10,000 rpm. After 30 minutes, adjust with acetic acid The pH is 3-4, then pour the homogenized emulsion into a three-necked flask, put it in a constant temperature water bath, and add 80 parts of etherified melamine resin dropwise under the condition of stirring at a stirring speed of 300 rpm, and raise the temperature to 56°C , keep warm for 2 hours to build a single-layer wall; after cooling the system to room temperature, add 80 parts of etherified melamine resin dropwise under stirring conditions, raise the temperature to 70°C, keep warm, and carry out the second wall build. 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 ...
