Example Embodiment

[0060] The application also provides a preparation method of the above-mentioned three-dimensional dry non-woven composite material, comprising the following steps:

[0061] Step 1: stacking the water-repellent non-woven fabric and the hydrophilic non-woven fabric to form a composite material layer.

[0062] In one embodiment, the composite material layer is formed by stacking the water-repellent non-woven fabric and the hydrophilic non-woven fabric, which can be as follows: the composite material is fabricated by a composite process of the water-repellent non-woven fabric and the hydrophilic non-woven fabric. Floor.

[0063] Preferably, the compounding process includes any one of glue compounding, spunlace compounding, acupuncture compounding, ultrasonic and thermal compounding, and the compounding process is used for stacking, which can prevent the water-repellent non-woven fabric and the hydrophilic non-woven fabric from intermingling. Inter-layering to improve product rel...

Example Embodiment

[0073] Example 1

[0074] The water-repellent non-woven fabric of the surface layer 10 is a water-repellent cotton spunlace non-woven fabric of about 25g / ㎡, the fiber fineness is 0.8-4.0dtex, the fiber length is 15-45mm, the mesh size is 4-50 mesh, and the bottom layer is 20 Hydrophilic non-woven fabric adopts 12-40g / m 2 Multi-hydrophilic hot air cloth, the production process of the three-dimensional dry pure cotton spunlace non-woven composite material of Example 1 is as follows: Figure 4 shown, including the following steps:

[0075] 1) Material preparation: Prepare water-repellent raw cotton, ie, 100% natural, non-degreased cotton fiber for use.

[0076] 2) Flower cleaning: The raw cotton is cleaned by a cleaning machine, and the three threads and foreign objects in the raw cotton are screened out.

[0077] 3) Carding: It includes two parts: opening and carding, that is, the cotton fiber is opened into a single fiber state, which is convenient for the carding machine to...

Example Embodiment

[0088] Example 2

[0089] The surface layer water-repellent non-woven fabric is made of water-repellent cotton-containing spunlace non-woven fabric. The composition of the water-repellent cotton-containing spunlace non-woven fabric is a combination of 50% cotton + 50% polyester. Softness, while taking into account the hot-melt properties of the water-repellent non-woven fabric surface layer, it is convenient for hot-melt bonding with other hot-melt materials. The bottom hydrophilic non-woven fabric is 12-40g / m 2 Multi-hydrophilic hot air cloth, the production process of the three-dimensional dry cotton-containing non-woven composite material of Example 2 is as follows. image 3 shown, including the following steps:

[0090] 1) Preparation: Mix 50% raw cotton and 50% polyester fiber fully and prepare it for use.

[0091] 2) Blowing: The raw cotton and polyester are cleaned with a cleaning machine, and the three wires and foreign objects in the raw cotton are screened out.

Abstract

The invention provides a three-dimensional dry and comfortable non-woven fabric composite material and a preparation method and application thereof.The three-dimensional dry and comfortable non-woven fabric composite material comprises a water-repellent surface layer and a hydrophilic bottom layer, the composite material is integrally in a concave-convex shape and comprises protruding parts and concave parts which are arranged at intervals, and the water-repellent non-woven fabric covers the protruding parts and does not cover the concave parts; and the meshes of the water-repellent non-woven fabric face the concave part. The structural design of the three-dimensional dry and comfortable non-woven fabric composite material has two advantages that on one hand, the water-repellent non-woven fabric is arranged on the convex parts, so that liquid on the water-repellent non-woven fabric is easy to slide to the mesh positions, the water-repellent non-woven fabric cannot influence liquid infiltration, and the dry and comfortable performance is stable; on the other hand, the covering area of the meshes on the hydrophilic non-woven fabric can be increased due to the fact that the meshes of the water-repellent non-woven fabric face the concave parts, that is, the contact area of the hydrophilic non-woven fabric and liquid through the meshes of the water-repellent non-woven fabric is larger, and therefore the liquid absorption speed is increased, slippage and seepage are reduced, and the risk of liquid leakage of a sanitary product using the composite material is reduced.

Description

technical field [0001] The present application relates to the technical field of composite materials, in particular to a three-dimensional dry non-woven composite material and its preparation method and application. Background technique [0002] With the improvement of people's living standards, consumers have higher and higher requirements for the comfort and safety of sanitary products such as sanitary napkins and diapers. Due to its excellent skin-friendly and soft properties, spunlace non-woven fabrics can meet the needs of consumers for skin-friendly, comfort and safety, so they are more and more applied to the surface layer of sanitary products. Since the cellulose fiber itself has good water absorption, the spunlace non-woven fabric made of it will also have good water absorption, which will cause the spunlace non-woven fabric to be relatively wet when used on the surface layer of sanitary products. For sanitary napkins and diapers with high requirements, it is parti...
