Description

A double-layer spunlace nonwoven fabric for sanitary napkins

technical field

The utility model relates to a sanitary article, in particular to a double-layer spunlace non-woven fabric used for sanitary napkins.

Background technique

With the development of the economy and the improvement of living standards, people's consumption demand for disposable sanitary products is increasing. At the same time, as consumption concepts become more mature and open, consumers hope to use more comfortable, natural and safe products.

Common disposable hygiene products, such as sanitary napkins, panty liners, and diapers, generally use hot air and spunbonded non-woven fabrics as the surface layer. These non-woven fabrics are made of chemical fibers as raw materials, and their natural texture is poor when used. In addition, if the fiber production is not properly controlled, trace chemical substances such as catalysts and reactive monomers will remain; chemical fibers generally contain a certain amount of chemical oils, etc., which will bring potential safety risks to consumers.

In view of the above factors, some disposable sanitary products have begun to use cotton spunlace non-woven fabrics as an alternative surface layer. However, because the large functional groups of cotton fibers contain hydrophilic hydroxyl groups, the cotton fibers have certain moisture absorption and moisturizing capabilities, so when used as a surface layer, there will be greater rewetting, and consumers will have a strong sense of stuffiness. Adverse effects on consumer health. In addition, when producing non-woven fabrics through the spunlace process, due to the inherent process characteristics, it is impossible to produce non-woven fabrics lower than 30gsm, and cotton fibers are non-renewable fibers. The key is to achieve more than 30gsm, so there is a problem of consuming a lot of natural resources.

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides a soft and breathable double-layer spunlace nonwoven fabric which can be used for sanitary napkins, panty liners and diaper surface layers, replacing traditional chemical fiber nonwoven fabrics.

The technical scheme that the utility model solves its technical problem adopts is:

A double-layer spunlace non-woven fabric for sanitary napkins, which includes a fabric layer, a flow guide layer, an absorption layer, a protective bottom film, a self-adhesive release paper and a coating that are sequentially stacked from top to bottom. A structural adhesive layer is arranged between adjacent layers, and the fabric layer is composed of a double-layer structure, the upper layer is a cotton fiber layer, and the lower layer is a mixed fiber layer.

The all-cotton fiber layer is composed of 100% cotton fibers.

The grammage of the all cotton fiber layer is 15-20 grams per square meter.

The weight of the mixed fiber layer of the fabric layer is 15-20 grams per square meter.

The grammage of the fabric layer is 30-40 grams per square meter.

The thickness of the fabric layer is 0.3-1.3 mm.

The beneficial effects of the utility model are: the fabric layer of the utility model adopts a double-layer combination method pioneeringly, and adopts a two-layer structure, that is, the upper layer uses cotton fibers, and the lower layer uses a mixed fiber structure to be formed at one time through the spunlace process. It not only enables consumers to contact with the natural cotton fiber layer to achieve a soft and safe experience, but also quickly conducts liquid through the mixed fiber layer of the lower layer, reducing stuffiness and increasing comfort. At the same time, due to the double-layer combination, the consumption of cotton fibers is greatly reduced, which is more economical and environmentally friendly. This material can be used for sanitary napkins, panty liners and diapers, replacing traditional pure chemical fibers or pure cotton non-woven fabrics. .

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is the structural representation of the utility model.

Fig. 2 is a structural schematic diagram of the fabric layer.

Detailed ways

Referring to Figure 1 and Figure 2, a double-layer spunlace non-woven fabric for sanitary napkins, the sanitary napkin includes fabric layer 1, flow guide layer 2, absorbent layer 3, protective bottom film 4, Adhesive release paper 5 and envelope 6, a structural adhesive layer is arranged between the above-mentioned adjacent layers, the fabric layer 1 is composed of a double-layer structure, the upper layer is a cotton fiber layer 21, and the lower layer is a mixed fiber layer 22, The grammage of the fabric layer is 30-40 grams per square meter. The fabric layer 1 of the present utility model, that is, the double-layer spunlace non-woven fabric pioneeringly adopts a double-layer combination, and adopts a two-layer structure, that is, the upper layer is used Cotton fibers and the mixed fiber structure for the lower layer are formed at one time through the spunlace process. It not only enables consumers to contact with the natural cotton fiber layer to achieve a soft and safe experience, but also quickly conducts liquid through the mixed fiber layer of the lower layer, reducing stuffiness and increasing comfort. At the same time, the double-layer combination method greatly reduces the consumption of cotton fibers, which is more economical and environmentally friendly. This material can be used for sanitary napkins, panty liners and diapers, replacing traditional pure chemical fibers or pure cotton non-woven fabrics.

In this embodiment, the fabric layer 1, that is, the double-layer spunlace nonwoven fabric, has multiple forms. The first way is that the upper layer of the fabric layer 1 is made of 100% cotton fiber, and the lower layer is made of 50% viscose. Glue fiber and 50% lyocell fiber are mixed and carded; the second way is that the upper layer of the fabric layer 1 is made of 100% cotton fiber, and the lower layer is made of 50% viscose fiber and 50% polyester fiber. The third way is that the upper layer of the fabric layer 1 is made of 100% cotton fiber, and the lower layer is formed by mixing and carding 50% lyocell fiber and 50% polyester fiber, and the lyocell fiber in these three ways , English name: Lyocell fiber, is a utility model of the German Akzo-Nobel company. It was officially named by the International Man-made Fibers and Synthetic Fibers Committee in 1989. The dry strength is slightly lower than polyester, but significantly higher than ordinary viscose fiber. The wet strength ratio Viscose fiber has been significantly improved. It has a pearly luster, good drapability, air permeability and hygroscopicity. The production process of lyocell fiber is green fiber without chemical reaction.

In addition, in this embodiment, the thickness of the fabric layer 1, that is, the double-layer spunlace nonwoven fabric, is 0.3-1.3 millimeters, and the weight of the fabric layer 1 is controlled respectively, and the grammage of the all-cotton fiber layer is 15-1.3 mm. 20 grams per square meter, the weight of the mixed fiber layer is 15-20 grams per square meter, on this basis, the entire double-layer spunlace nonwoven fabric is comfortable, soft and skin-friendly when in contact with consumers, and the other side is more absorbent conduction.

In this embodiment, a structural adhesive layer is provided between adjacent layers using common techniques in the art, a first structural adhesive 8 is provided between the fabric layer 1 and the flow guide layer 2, and the flow guide layer 2 and the flow guide layer The second structural glue 9 is arranged between the absorbing layer 3, the third structural glue 10 is arranged between the absorbing layer 3 and the protective base film 4, and the For the fourth structural adhesive 11 , an adhesive 12 is arranged between the adhesive release paper 5 and the envelope 6 .

The diversion layer 2 is a PE perforated film, and the absorption layer 3 is made of perforated dust-free paper, which is used in conjunction with the double-layer spunlace non-woven fabric to increase water permeability and air permeability.
