A kind of unidirectional water-conducting mask base material and preparation method thereof

Abstract

The invention relates to a unidirectional water-conducting mask base material, which has a three-layer structure, the upper layer is hydrophobic modified polyester fiber, the middle layer is chitosan modified polyvinyl alcohol fiber, and the lower layer is viscose fiber; hydrophobic modified polyester fiber, The chitosan-modified polyvinyl alcohol fiber and the viscose fiber are combed into a net and compounded, and then reinforced by hydroentanglement. The present invention uses three fiber layers of different materials for compounding, and the obtained mask base material has one-way vertical water conduction, so that after the mask absorbs the nutrient essence, it can vertically transmit the nutrient essence from top to bottom in a directional manner, so that the absorption of nutrients The liquid efficiency is maximized, and the nutrient solution is not wasted. The surface density of each fiber layer and the angle of compounding, and the synergistic effect of the upper, middle and lower fiber layers make the resulting mask base material have excellent performance, unidirectional water-conducting performance, excellent water absorption and water retention performance, and good air permeability Moisture permeability and humidity. It ensures that the facial skin can fully absorb the nutrient solution, and the texture of the mask is comfortable and soft.

Description

technical field [0001] The invention belongs to the technical field of mask substrates, and in particular relates to a unidirectional water-conducting mask substrate and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, women and even men pay more and more attention to skin care, and in the daily use of skin care products, facial mask products are at the forefront. There are many kinds of facial masks, which can be mainly divided into four categories according to the product form: facial mask (sticking mask), gel mask, powder mask, and cream mask. Among them, facial masks are easy to carry, simple and quick to use, and can be stored for a long time, making them the most popular facial masks among consumers. According to the data, more than 80% of the facial masks currently on the market are facial masks. This kind of facial mask mainly uses non-woven base fabric as a carrier, which can improve the skin's absorptio...

Problems solved by technology

However, the raw materials and preparation methods of some existing unidirectional water-conducting materials mostly adopt chemical finishing methods, such as fluorine-containing hydrophobic treatment, which is not conducive to the environment and human health, and is not suitable for use as mask materials.

There is also a plasma method modification, which avoids the use of toxic chemical finishing agents, but this method is costly and has obvious time constraints, and the effect of one-way water conduction after treatment lasts for a short time
