Description

Preparation process of modified film cloth and application thereof

This application claims priority to Chinese Patent Application No. 200910918852.2, entitled "Preparation Process and Application of Modified Membrane Fabric" on September 30, 2017, the entire contents of which are incorporated by reference. In this application.

Technical field

The invention belongs to the field of film articles, and in particular relates to a process for preparing a modified film cloth and an application thereof.

Background technique

The mask or the like uses a film cloth as a substrate or a carrier, and is used in combination with a certain amount of water, functional ingredients or nutrients, and belongs to a film product. At present, the most common facial mask cloths include non-woven facial mask cloth and silk facial mask cloth. The mask products on the market usually need to be immersed in the water system environment, such as the essence liquid, and packaged for sale.

In order to obtain a better skin feel and to avoid the evaporation of the essence quickly, it is necessary to add the oil phase and the water phase to the essence system of the mask, and since there are both the oil phase and the water phase in the liquid environment, it is necessary to be included. Surfactants such as emulsifiers and defoamers; additives such as preservatives, bactericidal and bacteriostatic agents are added to the mask because the water system is highly susceptible to deterioration, oxidation, and fermentation after being combined with functional ingredients or nutrients. In order to ensure the water retention of the mask and the quality of the shelf life.

However, preservatives and bacteriostatic agents in products such as masks can bring about a series of negative effects, such as allergies and contact dermatitis, which can not only protect the skin, but also have the desired effect, but will damage the skin; If it is not included in the anti-corrosion system, then the quality of its products during the shelf life is difficult to guarantee.

To this end, the Applicant has developed a modified film cloth coated with a thickening agent which is prepared by infiltration of a film cloth in an aqueous solution containing a thickener and dehydration. When the modified film cloth is in contact with water during use, the thickener on the surface can combine with water molecules to form a water retention system which is more retentive than pure water, so that the evaporation rate is slow and the skin residence is stronger. At the same time, since the modified film cloth is not in contact with the antiseptic system during the storage period, the product itself is safer, and the user can be less exposed to anti-health additives such as preservatives and antibacterial agents. However, since the modified film cloth needs to be dehydrated in the preparation process, it is impossible to add a volatile component to the modified film cloth, and if a heat sensitive component is added to the modified film cloth, the dehydration method can only be lyophilized. The manufacturing cost of the modified film cloth is increased.
