Embodiment 1

[0050] see figure 1 , shown in the figure is a multi-layer adhesive-free composite non-woven fabric containing natural fibers, including a substrate layer 100 and a fiber layer 200 . The fiber layer 200 is composited on one surface of the base material layer 100 . The base material layer 100 may be composed of one layer of fiber base layers, and of course may also be composed of multiple layers of fiber base layers.

[0051] A kind of preparation method that is used to prepare above-mentioned multi-layer adhesive-free composite non-woven fabric containing natural fiber of the present invention, see image 3 , including the following steps:

[0052] Step S1 , preparing a substrate layer 100 . The substrate layer 100 is a synthetic polymer fiber non-woven fabric layer made by a hot-air fabric forming process, a spunbond fabric forming process, a hot-rolled fabric forming process or a melt-blown fabric forming process, wherein the synthetic polymer fiber non-woven fabric layer...

Embodiment 2

[0062] see figure 2 , this embodiment is substantially the same as Embodiment 1, the difference is that: the base material layer 100a is composed of a soft layer 110a and a flow guide layer 120a that are combined from top to bottom, that is, the base material layer 100a incorporates a flow guide function, It has excellent conductivity properties. When the composite non-woven fabric of this embodiment is used in the surface layer of the sanitary care product in direct contact with human skin, it can replace the diversion layer in the sanitary care product, making the structure of the sanitary care product simpler and simplifying the hygiene care. The production process of the article reduces the production cost of the hygiene care article and improves the production efficiency of the hygiene care article.

Embodiment 3

[0064] The multilayer non-adhesive composite nonwoven fabric containing natural fibers of the present invention can be applied to health care products, and can be used as the surface layer of the health care products in direct contact with human skin. The hygienic care article can be one of sanitary napkin, sanitary pad, baby diaper, baby diaper, baby diaper, adult diaper, adult diaper, adult diaper, nursing pad, facial mask, and cotton pad.

[0065] The base material layer 100 or 100a of the multi-layer non-adhesive composite nonwoven fabric containing natural fibers of the present invention is basically the same as the material adopted by the conventional polymer fiber nonwoven fabric, so it only needs to be compared with the conventional fiber nonwoven fabric. The surface layer can be simply replaced, and there is basically no need to make too many process adjustments during use, and the production line does not need to be changed.

Abstract

The invention discloses a multi-layer non-glued composite non-woven fabric containing natural fiber. The fabric comprises a base material layer; a fibrous layer is composited on the surface of the base material layer and the fibrous layer comprises at least natural fiber. The invention also discloses a preparation method and applications of the multi-layer non-glued composite non-woven fabric containing natural fiber. The provided multi-layer non-glued composite non-woven fabric containing natural fiber balances the advantages and merits of various kinds of fibers; adhesive agent is needless; integral online formation and segmented independent formation are fulfilled; a special composite structure formed by the fibrous layer containing natural fiber and other non-woven fabric base material layer has good physical and chemical property and operating performance such as safety, low sensitivity, softness, being skin-friendly, diversion, capable of breathing and increasing intensity, etc.; in this way, the natural fiber consumption is greatly reduced, manufacture cost is reduced and environmental protection requirement is meet.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics for sanitary products, in particular to a multi-layer non-adhesive composite non-woven fabric containing natural fibers and its preparation method and application. Background technique [0002] Non-woven fabric (English name: Non Woven Fabric or Nonwoven cloth), also known as non-woven fabric, is composed of oriented or random fibers. It is a polymer fiber base cloth material produced by a non-woven process. Light weight, low cost, recyclable and so on. Common nonwoven processes include: spunbond process, melt blown process, hot air process, hot rolling process, spunlace process, etc. Commonly used fibers include artificially synthesized polymer fibers (such as PP, PE, PET, PA, etc.) and natural fibers (such as cotton fibers, viscose fibers, chitin fibers, bamboo charcoal fibers, etc.). [0003] At present, artificially synthesized polymer fiber non-woven fabrics made by hot air, spunb...
