Embodiment 1

[0020] The first step: preparation of lavender essential oil microcapsules:

[0021] 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.

[0022] 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...

[0031] The first step: preparation of lavender essential oil microcapsules:

[0032] 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.

[0033]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...

Embodiment 3

[0042] The first step: preparation of lavender essential oil microcapsules:

[0043] 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.

[0044] 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-chai...

Abstract

The invention discloses a preparation method of a lavender essential oil-containing microcapsule finishing agent; the preparation method includes the steps: preparing short-chain glucan; preparing ocentyl succinic acid short-chain glucan; preparing an ocentyl succinic acid short-chain glucan nano particle powder; dissolving the ocentyl succinic acid short-chain glucan in deionized water, adding Tween 80, carrying out ultrasonic treatment, and gelatinizing until the solution is transparent; dissolving lavender essential oil in anhydrous ethanol, and adding lecithin to obtain a lavender essential oil solution; adding the lavender essential oil solution into the ocentyl succinic acid short-chain glucan solution, shearing and homogenizing to obtain an ocentyl succinic acid short-chain glucan-lavender essential oil nano emulsion, and freeze-drying to obtain lavender essential oil microcapsules; and dissolving the microcapsules in purified water, and mixing to obtain the lavender essential oil microcapsule finishing agent. The ocentyl succinic acid short-chain glucan is adopted as a wall material, so that the microcapsules can be adhered onto a handkerchief and can control slow release of the lavender essential oil for a long time.

Description

technical field [0001] The invention belongs to the textile field and relates to the technical field of handkerchief finishing, in particular to a preparation method of microcapsules containing lavender essential oil and its application on handkerchiefs. Background technique [0002] With the improvement of living standards, people are beginning to pay more and more attention to the quality of life. Traditional handkerchiefs have a single function and cannot meet people's needs for a healthy life. Therefore multifunctional handkerchief is the research direction of 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] Lavender essential oil is a pure natural plant essential oil. It has a good e...
