The new Quanzhou diapers have a smell, which may be derived from the raw materials of the diapers
Many friends reported that after they bought Quanzhou diapers, they found a smell. Some people say that these flavors may be affected by the production process. The flavors in the production of Quanzhou diapers are also considered to be the smell of disinfectant or the smell of diapers that are not good enough. For Quanzhou diapers, there is a certain taste, which is likely to be derived from the raw materials. Generally, the diaper structure is divided into three layers: surface covering layer, absorbent core layer and bottom layer. The surface layer is made of non-woven fabric, the absorbent core layer is made of absorbent beads and fluff fibers, and the bottom material is mainly made of PE film or PE film + non-woven fabric. Let's take a look at the surface coating first. The surface layer of the diaper is mainly non-woven fabric, which has the advantages of good strength, breathable and waterproof, environmental protection, flexibility, non-toxic and odorless, and low price. It can be seen that the smell of diapers has little to do with non-woven fabrics. The second is the absorbent core, that is, absorbent beads and fluff fibers. Absorbent beads are super absorbent resins, mostly polyacrylic acid, mainly sodium polyacrylate. Sodium polyacrylate is white powder or granule, odorless and tasteless, swells in water, and is easily soluble in aqueous caustic soda solution; it has strong hygroscopicity. The words odorless and tasteless tell us the smell of diapers and come from here. Finally, the outer layer (bottom layer) of the diaper is the PE film. PE film is also called polyethylene film, which is mainly used to prevent urine penetration. So does the polyethylene film itself taste? Polyethylene is odorless, non-toxic, has excellent low temperature resistance and good chemical stability. Note that polyethylene is'odorless' instead of'odorless'. From this point of view, polyethylene film is not tasteless, but smellless. Dissecting layer by layer, if you insist that the taste of the diaper comes from the raw material, it seems that the bottom layer (PE film) is more suspect. From this reasoning, the taste after opening the diaper may come from the bottom layer (PE film). The above information is compiled from: Quanzhou diaper manufacturers.
