Embodiment 1

[0019] The first step: preparation of rose essential oil microcapsules:

[0020] 1) Preparation of short-chain glucan: dissolve 10 g of waxy starch in water, heat gelatinization in an oil bath at 120° C., cool to 60° C., add pullulanase for debranching, and the addition of pullulanase The amount is 30 ASPU / g starch dry basis. After enzymolysis for 8 hours, centrifugation at 11000rpm for 5 minutes, put the supernatant in a water bath at a temperature of 100°C and keep it for 30 minutes to inactivate the enzyme to obtain short-chain glucan and its solution. Short-chain dextran and its solution are freeze-dried to obtain short-chain glucan powder.

[0021] 2) Preparation of octenyl succinic acid short-chain glucan: the short-chain glucan powder obtained in step (1) was formulated into an aqueous solution with a mass fraction of 5%, and gelatinized by heating in an oil bath at 120° C. for 30 minutes, Cool down to 50°C after the oil bath, adjust the pH value of the short-chain dex...

Embodiment 2

[0028] The first step: preparation of rose essential oil microcapsules:

[0029] 1) Preparation of short-chain glucan: dissolve 10 g of waxy starch in water, heat gelatinization in an oil bath at 120° C., cool to 60° C., add pullulanase for debranching, and the addition of pullulanase The amount is 35 ASPU / g starch dry basis. After enzymolysis for 10 hours, centrifuge at 11000rpm for 5 minutes, put the supernatant in a water bath with a temperature of 100°C and keep it for 30 minutes to kill the enzyme, and then obtain short-chain glucan and its solution. Short-chain dextran and its solution are freeze-dried to obtain short-chain glucan powder.

[0030]2) Preparation of octenyl succinic acid short-chain glucan: the short-chain glucan powder obtained in step (1) was formulated into an aqueous solution with a mass fraction of 10%, and gelatinized by heating in an oil bath at 120° C. for 30 minutes, Cool down to 50°C after the oil bath, adjust the pH value of the short-chain dex...

Embodiment 3

[0037] Step 1: Prepare rose essential oil microcapsules:

[0038] 1) Preparation of short-chain dextran: dissolve 15 g of waxy starch in water, heat gelatinization in an oil bath at 120° C., cool to 60° C., add pullulanase for debranching, and the addition of pullulanase The amount is 30 ASPU / g starch dry basis. After enzymolysis for 8 hours, centrifugation at 11000rpm for 5 minutes, put the supernatant in a water bath at a temperature of 100°C and keep it for 30 minutes to inactivate the enzyme to obtain short-chain glucan and its solution. Short-chain dextran and its solution are freeze-dried to obtain short-chain glucan powder.

[0039] 2) Preparation of octenyl succinic acid short-chain glucan: the short-chain glucan powder obtained in step (1) was formulated into an aqueous solution with a mass fraction of 5%, and gelatinized by heating in an oil bath at 120° C. for 30 minutes, Cool down to 50°C after the oil bath, adjust the pH value of the short-chain dextran to 8, the...

Abstract

The invention provides a preparation method of a finishing agent containing rose essential oil microcapsules. The preparation method includes the steps of short-chain glucan preparation, octenyl succinate short-chain glucan preparation, octenyl succinate short-chain glucan nano-particle preparation and preparation of nano-emulsion containing embedded rose essential oil. The rose essential oil is dissolved in absolute ethyl alcohol, lecithin is added into the absolute ethyl alcohol to obtain rose essential oil solution, the rose essential oil solution is added into the nano-emulsion containingthe embedded rose essential oil, sheared and homogenized to obtain octenyl succinate short-chain glucan-rose essential oil nano-emulsion, the octenyl succinate short-chain glucan-rose essential oil nano-emulsion is freeze-dried to obtain the rose essential oil microcapsules, and the microcapsules are dissolved in purified water and mixed to obtain the finishing agent containing the rose essentialoil microcapsules. The invention further discloses an application of the finishing agent to cotton piece goods. Efficient and long-term rose essential oil slow release functions can be achieved, people can feel comfortable and delighted in spirit, anxiety and pressure are relieved, and sleep is helped.

Description

technical field [0001] The invention relates to the field of textiles, and relates to a finishing technique for cloth flower art, in particular to a preparation method and application of a finishing agent containing rose essential oil microcapsules. Background technique [0002] With the improvement of living standards, people are beginning to pay more and more attention to the quality of life. The traditional cloth flower art has a single function, which can no longer meet the needs of people's pursuit of a healthy life. Therefore multi-functional cloth flower art is the research direction in textile field now. With the development of microcapsule technology, the application of microcapsules as a finishing agent in the textile field will increase the functionality of textiles. The application of microcapsules in the finishing of textiles has become one of the important ways to endow products with multifunctionality. [0003] Rose essential oil is a pure natural plant esse...
