Embodiment 1

[0037] Preparation of modified melamine resin:

[0038] Weigh melamine resin and epresteramine (the mass ratio of melamine resin to epresteramine is 1:2.8) and dissolve them in DMF (the solid-to-liquid ratio of melamine resin to DMF is 1:17 g / mL). , slowly drop DMAP (the mass ratio of DMAP to melamine resin is 1.2:1), react for 10 minutes, then add EDC (the mass ratio of melamine resin to EDC is 1:1.1), naturally raise the temperature to 23°C, and react for 20 hours. Thin layer chromatography (TLC) was used to check whether the reaction was complete. The reactant was poured into water, extracted with ethyl acetate and washed with saturated brine respectively, the organic phase was dried overnight with anhydrous sodium sulfate, filtered, and separated by silica gel column chromatography (eluents were ethyl acetate and petroleum ether, the volume ratio was 1:2), vacuum-dried after vacuum distillation to obtain modified melamine resin.

Embodiment 2

[0047] The difference between the preparation of modified melamine resin and Example 1 is that the mass ratio of melamine resin to epresteramine is 1:2.5, and other conditions are fine-tuned according to the actual situation of the reaction;

[0048] The difference between the preparation of a kind of lavender essence microcapsule and embodiment 1 is:

[0049] The core-to-wall ratio in the microcapsule structure is 1.1:1;

[0050] The amount of polymer emulsifier in step S1 is 14.1% of the total mass of lavender essence; the emulsification time is 12min; the stirring speed is 14500r / min;

[0051] In step S2, the pH value of the emulsion is adjusted to 4.5 with acetic acid; the constant temperature is 60° C., and the temperature is kept for 1 hour.

[0052] The average particle size of the prepared microcapsules is 3.0 μm, and the particle size distribution is 1.0-3.5 μm.

[0053] The finishing solution is: 0.5% of lavender essence microcapsules (calculated by water weight), ...

Embodiment 3

[0057] The difference between the preparation of modified melamine resin and Example 1 is that the mass ratio of melamine resin to epresteramine is 1:2.6, and other conditions are fine-tuned according to the actual situation of the reaction;

[0058] The difference between the preparation of a kind of lavender essence microcapsule and embodiment 1 is:

[0059] The core-to-wall ratio in the microcapsule structure is 1.4:1;

[0060] The amount of polymer emulsifier in step S1 is 14.7% of the total mass of lavender essence; the emulsification time is 10min; the stirring speed is 14000r / min;

[0061] In step S2, the pH value of the emulsion is adjusted to 5.0 with acetic acid; the constant temperature is 63° C., and the temperature is kept for 1.5 hours.

[0062] The average particle size of the prepared microcapsules is 2.5 μm, and the particle size distribution is 0.5-3.0 μm.

Abstract

The invention discloses lavender essence microcapsule finishing liquid, and relates to the technical field of functional finishing liquid and application thereof. A lavender essence microcapsule is prepared from a core material prepared from a lavender essence and a wall material prepared from modified melamine resin, and the ratio of the core to the wall in the microcapsule structure is (1-1.5) to 1. The lavender essence microcapsule finishing liquid is specifically prepared from the lavender essence microcapsule, a cross-linking agent and water. When the microcapsule finishing liquid is used for finishing the fabric, the soaping resistance, scrubbing resistance and wear resistance of the fabric can be effectively improved, the release of fragrance is delayed, the fragrance retention time is prolonged, and the health-care effect is enhanced. The textile additional value is greatly improved, after being finished, the fabric can be used as home textile products such as pillowcases and bed sheets, further can be used as underwear, children's garments and the like, is safe, environment-friendly, fragrant and pleasant, and has a wide market space.

Description

technical field [0001] The invention belongs to the technical field of functional finishing liquid and its application, and in particular relates to a lavender essence microcapsule finishing liquid. Background technique [0002] In recent years, with the continuous improvement of people's living standards, the demand for textiles is not limited to warmth, comfort and beauty, but also has a wider demand for its functionality and safety. Fragrance finishing is to extract essence from natural plants to make microcapsules, which are organically combined with textile fibers through special technology, endowing textiles with various fragrances, playing a pleasant mood, relieving pressure, calming nerves and other health care functions, beneficial to physical and mental health, At present, the widely used fragrance finishing technology at home and abroad includes fruit fragrance, such as apple, lemon, etc.; flower fragrance, such as jasmine flower fragrance, rose fragrance, etc. La...
