Embodiment 1

[0030] A preparation method of bacterial cellulose / nonwoven fiber composite facial mask base cloth, comprising the following steps:

[0031] (1) Prepare bacterial cellulose by static fermentation of Acetobacter xylinum of the genus Acetobacter: inoculate the Acetobacter xylinum species into the seed liquid (glucose: 20.0g / L; peptone: 3.0g / L; potassium dihydrogen phosphate: 1.0g / L; ammonium sulfate: 6.0g / L), cultivated at a speed of 150 rpm and a temperature of 30°C for 48 hours; to the prepared fermentation broth (glucose: 20.0g / L; yeast extract powder: 7.5g / L; Potassium dihydrogen phosphate: 5.0g / L; Calcium lactate: 0.2g / L; Sodium carboxymethyl cellulose: 0.4g / L) inoculate the above-mentioned cultivated seed liquid, and the inoculum size is 10% of the fermentation liquid volume %; the fermented liquid after the inoculation was pre-fermented and cultivated for 12 hours at a speed of 150 rpm and a temperature of 30°C; Under static culture for 12 hours, the bacterial cellulos...

Abstract

The invention discloses an efficient preparation method of bacterial cellulose / non-woven fiber composite mask base cloth. The efficient preparation method comprises the following steps of putting non-woven fiber base cloth into a culture medium according to set interval time in a period of preparing bacterial cellulose by fermentation, and controlling the thickness of the bacterial cellulose by utilizing the interval time, and preparing the bacterial cellulose / non-woven fiber composite mask base cloth in situ by virtue of a biological fermentation process. According to the efficient preparation method of the bacterial cellulose / non-woven fiber composite mask base cloth, continuous, batch and controllable preparation of the bacterial cellulose / non-woven material composite mask base cloth isrealized; and according to the prepared bacterial cellulose / non-woven material composite mask base cloth, the excellent fitness and adsorption / release performance of bacterial cellulose are reserved,meanwhile, an ultrathin bacterial cellulose film layer can be obtained by regulating and controlling the interval culture time, and therefore a bacterial cellulose film is guaranteed to have good airpermeability, and meanwhile, the material preparation cost can be saved to a certain extent.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a method for efficiently preparing a bacterial cellulose / nonwoven fiber composite mask base cloth. Background technique [0002] With the continuous improvement of people's living standards, more and more people begin to pay attention to personal skin maintenance and repair. At the same time, in modern society, people spend more and more time facing electronic display screens such as TVs, computers, and mobile phones, and the chances of skin being damaged by ultraviolet rays and electromagnetic radiation are increasing. Therefore, beauty and skin care products have played an increasingly important role in people's daily life in recent years. Among them, mask products temporarily isolate pollutants in the outside air by contacting with the skin, promote the expansion of skin pores, accelerate skin metabolism, provide moisture and nutrients needed by the skin, and re...
