Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabrics, in particular to a nano-ultrafine fiber non-woven fabric. Background Art

[0002] Non-woven fabrics, also known as non-woven fabrics, are made of directional or random fibers. They are called cloth because they have the appearance and certain properties of cloth. Non-woven fabrics have many advantages, such as moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in colors, low price, and recyclable. Non-woven fabrics are simple to manufacture, low in cost, and widely used.

[0003] Non-woven fabrics are usually used to make facial mask cloths. The existing facial mask cloths made of non-woven fabrics have a large porosity, resulting in poor water-locking and moisturizing performance. The mask essence on the mask cloth is easy to evaporate, thus affecting the mask effect; and the existing facial mask cloth itself has poor antibacterial properties. Utility Model Content

[0004] In order to solve the above problems existing in the prior art, the utility model provides a nano-ultrafine fiber non-woven fabric with good water-locking and moisturizing performance and good antibacterial and antimicrobial performance, which is particularly suitable for use as a facial mask cloth.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A nano-ultrafine fiber non-woven fabric comprises a bamboo fiber base, a nanofiber layer is arranged on the upper side of the bamboo fiber base, a fiber isolation layer is arranged on the lower side of the bamboo fiber base, and a viscose fiber layer is arranged on the lower side of the fiber isolation layer; the bamboo fiber base, the fiber isolation layer and the viscose fiber layer are compounded by hydroentanglement or needle punching, and the nanofiber layer and the bamboo fiber base are compounded by hot rolling. The nanofiber layer is very dense, forming a membrane-like fiber layer, which can effectively reduce the volatilization of water under the premise of being breathable, thereby achieving good water-locking and moisturizing performance; the bamboo fiber base has good antibacterial and antibacterial effects.

[0007] Preferably, the nanofiber layer is made of nanospun fibers, and the diameter of the nanospun fibers is 200nm-800nm.

[0008] Preferably, the bamboo fiber base layer is made of bamboo pulp fiber, and a plurality of concave cavities distributed in an array are evenly arranged on the lower surface of the bamboo fiber base layer, and the concave cavities are filled with bamboo charcoal fiber. The bamboo pulp fiber has good moisture absorption and air permeability and UV resistance; the bamboo charcoal fiber contains a large number of honeycomb microporous structures and has good adsorption properties. When used as a facial mask cloth, it can absorb impurities precipitated from the skin.

[0009] Preferably, the concave cavity is in a regular hexagonal structure, and the bottom of each concave cavity is provided with at least one air guide hole penetrating the bamboo fiber base layer. The air guide hole increases the overall air permeability.

[0010] Preferably, the ratio of the depth of the cavity to the thickness of the bamboo fiber base layer is 0.4-0.6; and the sum of the surface areas of the cavities per unit area accounts for 55-75%.

[0011] Preferably, the fiber isolation layer is made of viscose long fibers, and the viscose fiber layer is made of viscose short fibers. The fiber isolation layer is used to isolate the bamboo charcoal fibers in the concave cavity.

[0012] Preferably, the viscose fiber layer is provided with flow guide holes distributed in an array. When used for a facial mask cloth, the viscose fiber layer acts on the skin surface, and the flow guide holes are conducive to ventilation on the one hand, and facilitate the flow of facial mask essence and its effect on the skin on the other hand.

[0013] Therefore, the utility model has the beneficial effects of good water-locking and moisturizing performance and good antibacterial and antimicrobial performance. BRIEF DESCRIPTION OF THE DRAWINGS
