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 design of the surface layer, The colloid sprayed on the absorbent layer of sanitary products will directly penetrate into the surface layer through the large mesh of the surface layer, resulting in the risk of glue leakage on the surface layer and affecting the user experience of the product

Embodiment 1

[0045] In this embodiment, the technological process for preparing spunlace composite fabrics through viscose fibers includes:

[0046] 1. Prepare materials: prepare 100% viscose fiber for use;

[0047] 2. Carding: Use a carding machine to comb the viscose fiber;

[0048] 3. Laying: The viscose fiber mesh layer is laid vertically, and the viscose fiber mesh layer is used as the surface layer;

[0049] 4. Pre-wetting: Wet the viscose 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 viscose fiber web and the hot-air non-woven fabric have a preliminary combination of

[0050] 5. Spunlace: Use the high-pressure water flow of the spunlace machine to spunlace the viscose fiber web layer and the hot-air non-woven fabric on the front and back, so that the viscose fibers are entangled with each other. At the same time, the viscose fiber is also spunlace with the hot-air ...

Embodiment 2

[0060] In this embodiment, the technological process for preparing the spunlace composite fabric through 70% viscose fiber and 30% hemp fiber includes:

[0061] 1. Prepare materials: mix 70% viscose fiber and 30% hemp fiber evenly to obtain mixed fiber for use;

[0062] 2. Carding: It includes two parts: opening and carding, which is to open the mixed fiber into a single fiber state, so that it can be combed smoothly with a carding machine;

[0063] 3. Laying: use vertical laying to lay the mixed fiber mesh layer;

[0064] 4. Pre-wetting: Wet the mixed 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 mixed fiber web layer and the hot air non-woven fabric have a preliminary Combine;

[0065] 5. Spunlace: Use the high-pressure water flow of the spunlace machine to spunlace the mixed fiber web layer and the hot-air non-woven fabric on the front and back, so that ...

Abstract

The invention discloses a preparation method of a spunlace compound fabric. The preparation method comprises the following steps that spunlace compounding is carried out on a pre-wetted surface layer and a pre-wetted structural layer to obtain a compound surface layer; water repellent treatment is carried out on the compound surface layer to obtain a water-repellent compound surface layer; meshes are manufactured in the water-repellent compound surface layer by adopting a punching process; and the structural layer and a flow guide layer are compounded to obtain the spunlace compound fabric, so that the flow guide layer covers the meshes in the water-repellent compound surface layer, and the spunlace compound fabric is obtained. According to the preparation method of the spunlace compound fabric, after the surface layer and the structural layer are creatively subjected to spunlace compounding, the compound surface layer with higher strength can be obtained, so that the meshes with clearer edges are obtained, and the liquid absorption speed of the surface layer is ensured not to be hindered by fibers at the edges of the meshes; and besides, after the compound surface layer and the flow guide layer are compounded and the meshes of the compound surface layer are covered, 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, so that the spunlace compound fabric which is high in liquid absorption speed and free of glue leakage is obtained.

Description

technical field [0001] The invention relates to the technical field of sanitary products, in particular to a 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. Spunlace non-woven fabrics have excellent skin-friendly and soft properties, which can satisfy consumers. The demand for skin affinity, comfort and safety makes it more and more applie...
