Abstract

The invention relates to a four-layer composite water-absorbing sanitary material and a production method thereof and belongs to the field of nonwoven fabric production. The method specially includes: producing 100% viscose or 100% cotton fibers 30-40mm in length into a short fiber layer, producing polyester and viscose short fibers into a blended short fiber layer according to the proportion of 5:5, compositing a pulp layer produced by fluff pulp fibers with the short fiber layer and the blended short fiber layer, and performing drying, PE membrane spraying and winding to obtain the four-layer composite water-absorbing sanitary material, wherein the pulp layer is solidified between the short fiber layer and the blended short fiber layer. The production method has the advantages that the four material layers are composited online, and two online high-speed carding machines are used to form different-fiber-material and different-performance fiber meshes; the production method is simple in process, suitable for large-scale production and promising in application prospect, and the produced sanitary material is high in water absorption, capable of preventing leakage, soft, comfortable, low in cost and the like.

Description

technical field [0001] The invention relates to the field of non-woven fabric manufacturing, in particular to a four-layer composite water-absorbing sanitary material and a production method thereof. Background technique [0002] Absorbent hygienic materials are medical products and care products for incontinent people. Traditional materials are processed with toilet paper or single-layer non-woven fabric. The disadvantages of these products are thin thickness, poor water absorption, and poor cloth texture. Therefore, there is an urgent need in this area for a four-layer composite absorbent hygienic material with thick cloth surface feel, high hygroscopicity and soft comfort. Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the present invention provides a four-layer composite water-absorbing sanitary material and its production method. The material has the advantages of high liquid absorption, anti-leakage, softness and comfort...
