Problems solved by technology

[0004] Yet the dry facial film that above-mentioned method obtains also has several defectives, for example:
[0005] (1) The essence substances attached to the surface of the mask base fabric through post-finishing methods do not have high bonding fastness with the mask base fabric, and are easy to fall off during processing, causing losses
[0006] (2) The essence is directly exposed on the surface of the mask, and it is easily oxidized by the air during storage and becomes invalid
Therefore, vacuum or air-filled packaging must be used to isolate the air, but this will not only increase the cost, but also lose its effect after the mask is unpacked
[0007] (3) The existing fiber raw materials commonly used in the preparation of dry facial masks mainly include polyester fiber, polypropylene fiber, biomass fiber, etc., but the water absorption of these fibers is generally insufficient, so the facial mask cannot be removed in a short time after adding water and applying it. Quickly store water inside and promote the dissolution and release of essence substances, thereby affecting skin absorption

Abstract

The invention relates to the field of cosmetics, and discloses a preparation method of a high-moisture-retention dry-state essence mask with a temperature-sensitive absorption-promoting function, and the preparation method comprises the following steps: (A) carrying out alkali decrement treatment on polypropylene fibers containing alkali-soluble polyester; (B) carrying out plasma treatment on the polypropylene fiber in an oxygen atmosphere; (C) dipping the polypropylene fiber into the essence; (D) spraying the finishing liquid on the polypropylene fiber, and carrying out heating crosslinking treatment to obtain the mask fiber with a skin-core structure; and (E) preparing the high-moisture-retention dry-state essence mask by taking the mask fiber as a raw material. The interior of the fiber in the mask is of a porous structure and can load essence substances, and meanwhile the surface of the fiber is provided with a temperature-sensitive gel skin layer. When the mask is stored in a dry state, the quality guarantee period can be effectively prolonged, and when warm water is added into the mask, the mask can quickly absorb water and promote release of essence substances after being applied to the skin surface.

Description

Technical field [0001] The present invention relates to the field of cosmetics, and more particularly to a method of preparing a high moisturizing dummy sequester mask having a warm-sensitive absorption function. Background technique [0002] Most of the mask on the existing market is mostly a wet mask containing extractive liquid, in a wet rich water environment, in order to avoid the essence of essence or oxidation in the essence, it is often necessary to add some preservatives or antibacterial agents. The anticorrosive and the biotechnic bioethic is poor, so it is easy to cause negative effects such as skin allergy after frequent use of the mask. The stem mask which is obtained on the mask base fabric in a donor form can solve the above problems. Since the dummy mask can be stored under dry conditions, the shelf life is also superior to the wet mask even if a preservative or acetactic agent is not added. [0003] At present, the preparation of the current dry mask is to prep...
