Abstract

The invention discloses a multilayer compound wick material. The multilayer compound wick material comprises a non-woven fabric layer, wherein the upper surface and the lower surface of the non-woven fabric layer are respectively scattered with a wicking resin to form an upper wicking resin layer and a lower wicking resin layer, the upper wicking resin layer and the lower wicking resin layer are adhered with an upper wicking paper layer and a lower wicking paper layer formed by wicking paper through a hot melt adhesive respectively, and the non-woven fabric layer, the upper wicking resin layer, the lower wicking resin layer, the upper wicking paper layer and the lower wicking paper layer are compound-molded through roll compacting. The multilayer compound wick material has the advantages of high wicking time, small liquid reverse osmosis amount, large liquid storage capacity, lasting liquid storage time, dry and comfortable surface, and no skin dipping; a technology for producing the multilayer compound wick material has the advantages of simple process and less operation; and the multilayer compound wick material can be widely used as a main wicking material in infant and adult diapers and urine pads, a wicking material of women's sanitary wicking pads, and clinical nursing and health articles.

Description

technical field [0001] The invention relates to a non-woven fabric and its production process, in particular to a multi-layer composite liquid-absorbing core material and its production process. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers. They are a new generation of environmentally friendly materials. Low cost, recyclable and so on. For example, polypropylene (pp material) pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. It is called cloth because of its appearance and certain properties. Non-woven fabric is a kind of fabric formed without spinning and weaving. It is just oriented or randomly arranged textile short fibers or filaments to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. . Non-woven fabrics break through the tradi...
