Technical Field

The invention relates to a microporous mask spunlace material and a preparation method thereof, belonging to the field of spunlace non-woven fabrics.

Background

The facial mask is a common product in the field of beauty and skin care, the types of the facial mask are very many, and currently, more than 70 percent of facial masks use non-woven fabrics as carriers to carry essence to realize various beauty and skin care functions. The mask is used as a beauty and skin care product, and besides the beauty and skin care effect, the comfortable experience of consumers is also important. The comfort of the mask is mainly reflected in air permeability, moisture permeability, softness, skin adhesion and difficult deformation, so that the mask base cloth is required to have good air permeability, moisture permeability and softness. When the facial mask is used, in order to enable essence of the facial mask to be better absorbed and achieve the best beautifying and skin-protecting effects, the skin-sticking time of the facial mask is generally required to be 15-25 minutes, and in such a long time, if the air permeability is poor, the skin of a person feels sultry and uncomfortable, and even the use experience is seriously influenced by skin itch. The human face is irregular concave-convex face, so that the mask can be tightly attached to each part of the face when being attached to the skin, the skin can uniformly absorb nutrient substances, and the mask is required to be sufficiently soft and not easy to deform, and the normal activity is not influenced when the mask is attached. Meanwhile, in order to make the mask more beautiful when being attached to the skin, the embarrassment that the traditional mask is not transparent and is considered as 'ghost' is improved, the use in public places is not influenced, and the transparency of the mask can be improved to achieve the invisible effect. Because the beauty effect of the facial mask is realized by the nutrient solution carried by the base cloth, the base cloth of the facial mask is used as a carrier of the nutrient solution, and the using effect of the facial mask is directly influenced by the amount of the carried nutrient solution. The base cloth has too little liquid holding capacity and unobvious beautifying effect, and simultaneously, the facial mask is dried quickly due to the absorption of skin and the volatilization of the facial mask, so that the facial mask absorbs moisture from the skin and cannot play a role in maintenance, and therefore, the facial mask base cloth needs to have good liquid holding capacity. In order to ensure that the essence is uniformly distributed on the mask material, the uniformity of the base cloth must be good and not easy to deform. In summary, with the rapid development of the facial mask industry, people have higher and higher requirements on facial masks, which can be summarized as comfort, lightness, thinness, softness, skin-close, transparency, invisibility, uniformity and no deformation.
