preparation example Construction

[0036] The present invention also provides a preparation method of the modified membrane cloth, comprising:

[0037] 1. surface is coated with the preparation method of the film cloth of polymer, comprises the steps:

[0038] (a) Stirring and dissolving the high molecular polymer with water to prepare a high molecular polymer aqueous solution, the content of the high molecular polymer in the aqueous solution is preferably 0.01 to 50%, more preferably 0.1 to 20%;

[0039] (b), coating the aqueous solution obtained in (a) onto the film cloth, the coating method includes but not limited to soaking, spraying, spraying, roller or coating etc.;

[0040] (c), drying the membrane cloth obtained in (b) to remove moisture to obtain the desired modified membrane cloth, the drying methods include but not limited to drying, vacuum drying, freeze drying, microwave drying, infrared drying, RW thin layer drying Wait.

[0041] Ⅱ. the preparation method of the film cloth that surface is coate...

Embodiment 1

[0101] Add water and stir hyaluronic acid to dissolve it to make a polymer aqueous solution with a content of 1%. Spray the above aqueous solution onto the prepared cotton film cloth, put the above film cloth in an oven to dry to remove moisture, and obtain the prepared Coating polymer film cloth, the ratio of hyaluronic acid to film cloth is 10g / m 2 .

[0102] When in use, add purified water to the membrane cloth of the above-mentioned pre-coated polymer, and the addition amount is 200ml / m 2 , forming a new type of wet wipe with certain moisture retention and liquid retention;

[0103] Apply the new wet wipes on the skin surface, keep the film cloth in a vertical state, and keep it for more than 30 minutes, and the wet wipes are still moist and tightly attached to the skin surface. The results show that the wet tissue provided by Example 1 of the present invention has better moisture retention and retention.

Embodiment 2

[0108] Almond oil and polyvinylpyrrolidone are dissolved and dispersed in a mass ratio of 1:8 to obtain a dispersion;

[0109] The above polymer dispersion was mixed according to 10g / m 2 The ratio is sprayed onto the prepared cotton film cloth to obtain a pre-coated polymer film cloth;

[0110] When using, add purified water to the above-mentioned pre-coated polymer full-face film cloth, and the addition amount is 200mL / m 2 , forming a new type of wet wipe with certain moisture retention and liquid retention;

[0111] Apply the new wet wipes on the skin surface, keep the film cloth in a vertical state, and keep it for more than 30 minutes, and the wet wipes are still moist and tightly attached to the skin surface. The results show that the wet tissue provided by Example 1 of the present invention has better moisture retention and retention.

Abstract

The invention provides a modified membrane fabric and a preparation method and application of the modified membrane fabric. The surface of the modified membrane fabric is coated with a polymer or polymer dispersion, and the polymer in the polymer or polymer dispersion may be polysaccharide, polypeptide and protein, may be an artificial polymerized polymer or may be a modified natural high polymer material or a mixture thereof, including but not limited to one or more selected from the group consisting of gelatins (such as gelatin and gelatin hydrolysate), cellulose ethers (e.g., carboxymethyl cellulose and hydroxyethyl methyl cellulose), modified starches (e.g., pullulan and hydroxypropyl starch), PVP, PVA, hyaluronic acids, albumin, chitosan, dextran, Arabic gum, xanthan gum, carrageenan, pectin, konjac gum, agar, Carbomer, carrageenin, polyvinylpyrrolidone, polyacrylamide, polyacrylate and polyacrylic acid and its derivatives. When the modified membrane fabric comes across water in use, the polymer on the surface of the modified membrane fabric can bond with water molecules to form a water retention system which has better retention performance compared with pure water and enables an evaporation speed to be slower and retention performance on the skin to be better.

Description

[0001] This application claims the priority of the Chinese patent application submitted to the China Patent Office on April 03, 2014, the application number is 201410133947.X, and the title of the invention is "a modified membrane cloth, its preparation method and application", the entire content of which Incorporated in this application by reference. technical field [0002] The invention relates to the technical field of membrane products, in particular to a modified membrane cloth, its preparation method and application. Background technique [0003] 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 enviro...
