Problems solved by technology

However, due to the need for dehydration in the preparation process of this modified membrane cloth, it is impossible to add volatile components to the modified membrane cloth, and if you want to add heat-sensitive components to the modified membrane cloth, the dehydration method can only be freeze-drying. Resulting in an increase in the manufacturing cost of the modified membrane cloth

preparation example Construction

[0067] In the preparation process provided by the invention, the volatile components and / or heat-sensitive components are coated on the membrane cloth in the form of anhydrous coating liquid, without subsequent dehydration. Since dehydration is not required, the volatilization of volatile components during dehydration of the membrane cloth is avoided, so this process solves the problem that volatile substances cannot be added to the modified membrane cloth. At the same time, since dehydration is not required, heat-sensitive components can also be added to the modified membrane cloth without using a freeze-drying process. In addition, the preparation process provided by the present invention enables the thickener to be coated on the membrane cloth without being mixed with water or grease, which can shorten the rehydration time of the modified membrane cloth when rehydration is used.

Abstract

The invention belongs to the technical field of film products, and particularly relates to a preparation technology and application of modified film fabric. The preparation technology provided by the invention comprises the following steps: a), providing coating liquid, and then coating the surface of film fabric with the coating liquid to obtain the modified film fabric, wherein the coating liquid contains a volatile component and / or a heat-sensitive component and a non-volatile non-sensitive thickening agent and does not contain water; or b), providing the coating liquid, and then coating the surface of film fabric, precoated with the non-volatile non-sensitive thickening agent, with the coating liquid to obtain the modified film fabric, wherein the coating liquid contains the volatile component and / or the heat-sensitive component and does not contain water. According to the preparation technology of the modified film fabric provided by the invention, the volatile component can be added into the modified film fabric, and a freeze-drying dewatering way is not required during adding of the heat-sensitive component.

Description

technical field [0001] The invention belongs to the field of film products, and in particular relates to a preparation process of a modified film cloth and its application. Background technique [0002] Masks, etc. use film cloth as the substrate or carrier, and use it with a certain amount of water, functional ingredients or nutritional ingredients, which belong to film products. At present, the more common facial mask cloths include non-woven facial mask cloths and silk facial mask cloths. The facial mask products on the market usually need to soak these facial mask cloths in a water system environment, such as essence, to be packaged and sold. [0003] In order to obtain a better skin feel and avoid the essence from volatilizing quickly, it is necessary to add oil phase and water phase to the essence system of the mask, and since there are both oil phase and water phase in the liquid environment, it is necessary to include Surfactants such as emulsifiers and defoamers; s...
