Embodiment Construction

[0017] 1. Polymerization of lavender microcapsules

[0018] ①, the effect of skin core dosage on the inclusion of microcapsules

[0019] The experimental conditions are that the total amount of Tween-80 and Span-80 emulsifiers is 0.2g, the inclusion temperature is 45°C, and the time is 2h. The optimal ratio of the amount of skin to core material is 1:1.

[0020] ② Effect of emulsifier dosage ratio on inclusion effect

[0021] Under the experimental conditions that the skin-to-core ratio is 1:1, each is 4g, the inclusion temperature is 45°C, and the duration is 2h, it can be obtained that the optimal ratio of Tween-80 and Span-80 is 1:1.

[0022] ③. Effect of temperature on inclusion complexation

[0023] The experimental conditions are that the ratio of skin to core material is 1:1, each is 4g, the ratio of Tween-80 and Span-80 is 1:1, and the duration is 2h, the optimal temperature for inclusion is 45°C.

[0024] ④. Effect of duration on inclusion

Abstract

The invention provides development of a lavender sustained-release microcapsule and application thereof in textiles. The lavender microcapsule is characterized in that lavender essence is taken as a core material, urea resin is taken as a skin material, and an in-situ polymerization method is adopted for synthesizing the microcapsule, so that the microcapsule of the 'core-skin' structure is synthesized. The synthesized microcapsule is arranged on the textiles by adopting a 'padding method', which can improve the sustained release property and water wash resistance of the microcapsule.

Description

technical field [0001] This project involves the development of lavender sustained-release microcapsules and its application technology in textiles Background technique [0002] Expensive essences are highly volatile substances that dissipate quickly and have a short shelf life. The most effective way to make the essence long-lasting is to microencapsulate the essence, which can improve the physical properties of the embedded essence (such as the speed of fragrance emission), protect it from the influence of the environment, and improve the response of the encapsulated substance Activity, durability, heat sensitivity, pressure sensitivity and photosensitivity, etc.; release substances to the external environment continuously as needed. Microencapsulation can simplify many traditional processes, and it can also effectively solve many problems that cannot be solved by common technical means, such as: affected by light, heat, and oxidation, active ingredients volatilize, and e...
