Description

Corrosion-resistant diaper lapping material

Technical Field

The utility model relates to a wet technical field of urine especially relates to a wet overlap joint material of urine of corrosion resistance.

Background

The diaper is a daily use article for babies and is a general name of paper diapers, paper diapers and pull-up pants. The dry and comfortable diaper can keep the baby asleep all night, and is commonly called as the diaper due to strong water absorption. Wherein, the super absorbent resin (called macromolecule SAP for short) is a perfect material for making baby urine non-wet, which is made by using starch and acrylic acid salt as main raw materials; the outstanding characteristic is that the water absorption and water storage capacity is surprisingly large.

Modern diapers generally consist of three main parts, namely a surface coating layer, an absorption core layer and a base fabric layer. The surface coating layer is tightly attached to the body of a baby, can promote the urine to quickly permeate and effectively prevent the urine from permeating back, and keeps the surface layer of the diaper dry and comfortable. The absorbent core is a layered structure composed mainly of pure wood pulp (fluff pulp) and super absorbent resin (SAP), which can capture and rapidly absorb urine, disperse it, or diffuse it throughout the core by capillary action, and finally absorb and store it. The base fabric layer is preferably a nonwoven fabric which is comfortable to wear, and a relatively inexpensive PE film may be used.

As described above, the conventional diaper does not have the corrosion resistance, and the nonwoven fabric layer (or PE film) as the bottom layer located at the outermost side of the diaper does not have the function of water resistance and moisture permeability, and therefore, further improvement is required over the prior art.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a corrosion resistance's urine is not wet and is taken over material to solve the problem that above-mentioned background art part provided.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the corrosion-resistant diaper lapping material comprises a base cloth layer, a corrosion-resistant layer, an absorption core layer and a surface coating layer which are sequentially arranged from outside to inside, wherein the base cloth layer is a polytetrafluoroethylene film layer, and the corrosion-resistant layer is formed by weaving poly (m-phenyleneisophthalamide) fiber warp and polyphenylene sulfide fiber weft.

Further, the surface coating layer is made of non-woven fabric.

Further, the absorption core layer is of a laminated structure formed by pure wood pulp and super absorbent resin.

Furthermore, the polyisophthaloyl metaphenylene diamine fiber warp and the polyphenylene sulfide fiber weft are interwoven mutually.

Furthermore, the base cloth layer and the corrosion-resistant layer, the corrosion-resistant layer and the absorption core layer, and the absorption core layer and the surface coating layer are connected by a compound machine through a compound process.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a set up the base cloth layer into polytetrafluoroethylene thin layer, because polytetrafluoroethylene thin film is a micropore thin film, its micropore diameter ratio is little than the diameter of hydrone, but is big than the vapor molecule for the water droplet can not pass through, and the vapor can pass through, utilizes this kind of microporous construction can reach good waterproof moisture permeable function. Meanwhile, the polytetrafluoroethylene film has the characteristics of low friction coefficient and strong non-adhesiveness, so that the polytetrafluoroethylene film also has a dustproof effect.

The polyisophthaloyl metaphenylene diamine fiber is a novel high-tech synthetic fiber, has excellent performances of acid and alkali resistance, high temperature resistance, light weight and the like, and has good textile processability; the polyphenylene sulfide fiber has stable chemical properties, corrosion resistance and good spinning processability; therefore, the corrosion-resistant layer formed by weaving the polyisophthaloyl metaphenylene diamine fiber warp and the aromatic polyamide fiber weft has stable chemical property, excellent corrosion resistance effect and high temperature resistance.
