Embodiment 1

[0020] Preparation of PEG system chitosan quaternary ammonium salt essence microcapsules:

[0021] Prepare materials and experimental equipment, select essence, chitosan quaternary ammonium salt, polyethylene glycol 400 (PEG), and glutaraldehyde as materials, carry out experimental operations on a sterile operating table, and use electronic analytical balances to weigh raw materials. Weigh 6.7g of chitosan quaternary ammonium salt (150,000 molecular weight) and add water to dissolve it to 67g in a 250ml flask; add 0.05g of PEG (polyethylene glycol 400) and 20g of aldehydic rose type essence, and then heat it at a constant temperature using a heat collector Stir with a magnetic stirrer for 25-35min for emulsification, and the mechanical stirring speed is 1000rpm / min. After emulsification, use an ice bath to lower the temperature to 5°C (below 10°C), and adjust the mechanical stirring to 550rpm / min. Weigh 0.3g of the crosslinking agent glutaraldehyde and add deionized water to 1...

Abstract

The invention provides a long-acting and antibacterial chitosan essence microcapsule preparation method, which specifically comprises: 1, preparing materials and experimental equipment, wherein essence, a chitosan quaternary ammonium salt, polyethylene glycol 400 (PEG) and glutaraldehyde are selected as materials; 2, carrying out experimental operation on an aseptic operation table, weighing the raw materials by using an electronic analytical balance, weighing 5-7 g of the chitosan quaternary ammonium salt, placing in a 250 ml flask, adding water, and dissolving to achieve a weight of 50-70 g;and 3, adding 0.02-1 g of the polyethylene glycol 400 (PEG) and 15-30 g of the essence to the flask, and stirring for 25-35 min by using a heat collection type constant temperature heating magnetic stirrer at a mechanical stirring speed of 1000 rpm / min to emulsify. According to the present invention, the microcapsules produced by the method have high essence content, have wide adaptability compared with other commercially available essence microcapsules, and further have advantages of efficient antibacterial property; and with the long-acting and antibacterial chitosan essence microcapsule, the fragrance forming effect on fabrics is good, the time of the fragrance retained on fabrics is long, the fragrance explosion after kneading can be achieved, and the fragrance is retained on the fabric after the fabric is washed five times.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a method for preparing long-acting, antibacterial chitosan essence microcapsules. 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. Lavender is more pop...
