Introduction Of Raw Materials For Diapers

1.Raw materials for diapers

When we go to the supermarket to choose diapers, we see many brands of diapers on the shelves of the supermarket. Some diaper materials may be allergic to our babies, so we must be careful when choosing. Based on the above situation, this paper briefly introduces raw materials for diapers.

2. Core

Raw materials for diapers mainly include non-woven fabrics, toilet paper, fluff pulp, polymer water-absorbing resin, PE film, etc., vegetable fiber material fluff pulp, in order to enhance the absorption effect and lock moisture, a certain amount of polymer should be added to the absorbing layer Absorbent resin. The core key technology of diapers is the "core body". From a technical point of view, the core body of diapers has experienced three revolutions so far. Diapers are disposable products that can be discarded after one-time use. Environmentally friendly and degradable diapers are made of raw materials extracted from corn fiber, soybean fiber or buckwheat fiber. Special and adult only.

3. Improvement

Commonly used raw materials for diapers include non-woven fabrics, diversion layers, toilet paper, SAP, base film, waist elastic bands, etc. In actual production, some improvements have been made to these materials, as follows:

a. Non-woven fabrics: The functional classification of non-woven fabrics used in diapers is increasingly refined. Hydrophilic non-woven fabric on the surface, water-resistant non-woven fabric on the body, and non-woven fabric on the permeable layer;

b. Adhesive stickers: plastic stickers (general - mute) - non-woven fabric stickers - trick stickers;

c. SAP: The share of SAP in the core body is increasing, below 10%, and now it is generally around 30%-40%, and a single one is as high as 70%;

d. Bottom film: PE film or PE film + non-woven fabric;

e. Membranes: general membranes - breathable films - breathable composite films.

The primary reason we use diapers is convenience, which saves the trouble of changing and washing. In terms of the function of absorbing urine, the requirements for the functional quality of diapers are also getting higher and higher, no leakage of urine, no back seepage, breathable, skin care, beautiful and comfortable, which are equivalent to shorts worn outside. The development of diapers can be said to be carried out in many ways.
