preparation example Construction

[0021] A kind of preparation method of fragrance-slowing superhydrophobic cotton fabric provided by the invention comprises the following specific steps:

[0022] (1) Preparation of aromatic nanocapsules: dissolving cetyltrimethylammonium bromide in water to form an aqueous phase with a concentration of 0.1-5g / L, preferably 0.5-3g / L. Then configure the oil phase solution, in which the concentration of ethyl orthosilicate is 44%-82%, the concentration of aromatic substances is 3%-48%, and the concentration of hexadecane is 0-9%. The optimal reaction concentration is ethyl orthosilicate 61%-76%, aromatic substances 14%-37%, hexadecane 0-8%. Mix the above-mentioned oil phase and water phase according to the mass ratio of 0.09:1 and use high-speed emulsification to form a mixed liquid. The shear speed during emulsification is 1.2-2.5kr / min, and the emulsification time is 3-9min. The best emulsification shear The speed is 1.2-2.0kr / min, and the emulsification time is 5-9min. Afte...

Embodiment 1

[0026] Step 1: Prepare aromatic nanocapsules: dissolve cetyltrimethylammonium bromide in water to form a water phase with a concentration of 0.72g / L, and then configure an oil phase solution, wherein tetraethyl orthosilicate, lemon essential oil, ten The amount of hexane accounts for 75%, 21%, and 4% of the mass of the oil phase respectively, and the oil phase obtained above is added to the water phase, where the mass ratio of the oil phase to the water phase is 0.09:1, and the shear speed is 1.2kr / min After high-speed emulsification for 5 minutes, a mixed solution was formed, and the resulting mixed solution was transferred to a three-necked flask and heated to 35°C for 24 hours of heat preservation, and the stirring speed was maintained at 410r / min.

[0027] Step 2: Prepare fragrance-sustaining superhydrophobic cotton fabric: take the aqueous dispersion of aromatic nanocapsules obtained above, and spray it on cotton fabric (15cm×25cm), and dry it at room temperature to obtai...

Abstract

The invention provides a slow fragrance type and super-hydrophobic cotton fabric and a preparation method thereof. According to the invention, firstly, aromatic nano capsules are adoted to prepare slow fragrance type cotton fabrics. In this way, not only a rough structure is provided for the formation of a super-hydrophobic surface, but also the long-lasting fragrance retention performance of cotton fabrics is realized. Secondly, the prepared slow fragrance type cotton fabrics are treated in the aqueous solution of a water-repellent agent with the concentration thereof to be 10-80 g/L. Therefore, low-surface-energy substances are provided for the formation of the super-hydrophobic surface, and the release of the fragrance is further delayed. The method effectively improves the stability of aromatic substances, and prolongs the volatilization time of the fragrance. Moreover, the fabrics are good in friction resistance, washing resistance, self-cleaning property and antifouling property.

Description

technical field [0001] The invention belongs to the technical field of multifunctional fabrics, and in particular relates to a method for preparing fragrance-slowing superhydrophobic cotton fabrics. Background technique [0002] With the continuous improvement of people's living standards, people's awareness of wearing comfort, fashion and hygiene is increasing. It is required that textiles are not only comfortable to wear, but also have various functions such as fragrance, water repellency, and antifouling. [0003] Aroma has the effects of beautifying the human body, relieving stress, and relaxing muscles. Aroma molecules stimulate the olfactory nerve through the nose, and the olfactory nerve transmits the stimulation to the brain center, and the brain generates excitement. On the one hand, it controls the nerve activity and regulates the nerve activity; the entire internal environment. Aroma molecules can achieve internal conditioning by stimulating nerve therapy.
