Problems solved by technology

[0004] However, the preservatives and antibacterial agents in products such as facial masks will bring a series of negative effects, such as allergies and contact dermatitis, which will not only fail to protect the skin and achieve the desired effect, but will damage the skin; If it is not included in the anti-corrosion system, then it is difficult to guarantee the product quality during the shelf life

Embodiment 1

[0059] adding water and stirring tremella polysaccharide to dissolve, and making a high molecular polymer aqueous solution with a content of 0.8%;

[0060] Spray the above-mentioned aqueous solution onto the prepared cotton film cloth, and the ratio of tremella polysaccharide to the film cloth is 5g / ㎡ to obtain a pre-coated polymer film cloth;

[0061] Put the above-mentioned membrane cloth into an oven to dry and remove moisture, and use it as a pre-modified membrane cloth.

[0062] Stir and dissolve hyaluronic acid with water to make a 1% polymer aqueous solution;

[0063] Spray the above aqueous solution onto the pre-modified membrane cloth, the ratio of hyaluronic acid to the membrane cloth is 10g / m 2 , and remove moisture by infrared film drying to obtain a modified membrane cloth product.

[0064] When in use, add purified water to the above-mentioned modified membrane cloth, the addition amount is 200ml / m 2 , forming a new type of mask with certain moisturizing and l...

Embodiment 2

[0066] Almond oil and polyvinylpyrrolidone are dissolved and dispersed in a mass ratio of 1:8 to obtain a polymer dispersion;

[0067] The above polymer dispersion was mixed according to 2g / m 2 The ratio is rolled onto the prepared non-woven membrane cloth to obtain a pre-coated polymer membrane cloth, which is dried by an infrared film to remove moisture and used as a pre-modified membrane cloth.

Abstract

The invention relates to the technical field of film products, and relates to a preparation method of a film cloth, in particular to a modified film cloth prepared by a multi-layer modifying method and a product thereof. The modified film cloth provided by the invention has the characteristics that the moisturizing property is better, the skin retention property is stronger, and the additional anticorrosive system is not needed in storage and use; compared with the single-layer modified film cloth, the use experience is more comfortable, the dissolving and absorbing property of functional matters are better, and the like.

Description

technical field [0001] The invention relates to the technical field of film products, and relates to a preparation process of film cloth, in particular to a modified film cloth and its products prepared by a multi-layer modification method. Background technique [0002] Masks and wet wipes, etc. use membrane cloth as the base material or carrier, and use it with a certain amount of water, functional ingredients or nutritional ingredients, which belong to membrane 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 li...
