Problems solved by technology

[0004] There are many meshes on the surface layer of sanitary products, but many meshes have the problem of unclear edges; in addition, in order to make the liquid pass through the surface layer quickly, the mesh design of the surface layer is usually relatively large, due to the large mesh

Embodiment 1

[0046] In this embodiment, the process for preparing pure cotton spunlace composite fabrics from raw cotton fibers includes:

[0047] 1. Raw material preparation: prepare raw cotton fiber, that is, 100% pure natural cotton fiber without degreasing, for use;

[0048] 2. Carding: Use a carding machine to comb the raw cotton fibers;

[0049] 3. Laying the net: the viscose fiber net layer is laid by vertical net laying, and the raw cotton fiber net layer is used as the surface layer;

[0050] 4. Pre-wetting: Wet the raw cotton fiber web layer, and use the hot-air non-woven fabric as the structural layer, and unwind the hot-air non-woven fabric prepared in advance synchronously, so that the raw cotton fiber web and the hot-air non-woven fabric have a preliminary combination ;

[0051] 5. Spunlace: Use the high-pressure water flow of the spunlace machine to spunlace the raw cotton fiber web layer and the hot-air non-woven fabric on the front and back sides, so that the raw cotton ...

Abstract

The invention discloses a preparation method of a pure cotton spunlace composite fabric. The method comprises the following steps of preparing a surface layer from water-repellent cotton fibers, performing spunlace compounding on the pre-wetted surface layer and a structural layer to obtain a water-repellent all-cotton composite surface layer, preparing meshes in the water-repellent all-cotton composite surface layer by adopting a punching process, compounding the structural layer and a flow guide layer, and enabling the flow guide layer to cover the meshes in the water-repellent all-cotton composite surface layer, so that the pure cotton spunlace composite fabric is obtained. The water-repellent cotton fibers are creatively adopted to manufacture the water-repellent pure cotton surface layer, and after the water-repellent pure cotton surface layer and the structural layer are subjected to spunlace compounding, the water-repellent all-cotton composite surface layer with higher strength can be obtained, and the meshes with clearer edges are formed, so that it is guaranteed that the liquid absorption speed of the surface layer is not hindered by edge fibers of the meshes; and in addition, after the water-repellent all-cotton composite surface layer and the flow guide layer are compounded, the liquid absorption speed of the surface layer can be increased through the flow guide layer, and meanwhile the situation of glue leakage of the meshes of the surface layer can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of sanitary products, in particular to a pure cotton spunlace composite fabric and its preparation method and application. Background technique [0002] The materials used for the surface layer of sanitary products on the market can be divided into four categories, namely spunbonded fabric, hot air fabric, cast film, and spunlace nonwoven fabric. Spun-bonded non-woven fabrics, air-through non-woven fabrics, and cast films are all made of chemical fiber raw materials, which have good dry performance, but poor skin-friendly and comfortable properties. [0003] 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, and cotton spunlace nonwovens have excellent skin-friendly and soft properties, which can meet Consumers' demands for skin-friendliness, comfort, and safety make it more an...
