Double-layer spunlace non-woven fabric for sanitary napkin

Abstract

The invention discloses a double-layer spunlace non-woven fabric for a sanitary napkin. The sanitary napkin comprises a fabric layer, a fluid guiding layer, an absorption layer, a protective bottom film, an adhesive release paper and a coating film stacked in sequence from top to bottom. Structural adhesive layers are disposed between the adjacent layers. According to the fabric layer, a double-layer combination method is pioneeredly used and a double-layer structure is adopted, that is, the upper layer is made of all-cotton fibers and the lower layer is of a mixing fiber structure, the upperlayer and the lower layer are molded at a time through the spunlace process, so that a consumer touches the natural cotton fiber layer during use to achieve soft and safe experience, and the liquid isquickly transmitted through the mixed fiber layer in the lower layer to reduce dampness feeling and increases comfort, and the used amount of the cotton fibers is greatly reduced to achieve more economical and environmentally friendly effects. The double-layer spunlace non-woven fabric can be used for sanitary napkins and sanitary pad surface layers to replace traditional chemical fiber non-wovenfabrics.

Description

technical field [0001] The invention relates to a sanitary product, in particular to a double-layer spunlace nonwoven fabric used for sanitary napkins. Background technique [0002] 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. [0003] 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 ...

AI Technical Summary

Problems solved by technology

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. Gram is more than 30gsm, so there is a problem of consuming a lot of natural resources
