Each diaper has two primary parts: Diaper core  – the middle of the diaper where urine and liquid feces are absorbed and stored. Diaper chassis – the shell of the diaper holds the core together, attaches the diaper onto the baby, and creates a proper fit around the legs. Diaper Core The core is primarily composed of polypropylene, cellulose and a superabsorbent polymer.  Topsheet The topsheet is the part of the  diaper  which comes in contact with the baby’s skin. It has been specially designed to quickly transfer fluids to the core while remaining soft and dry to the touch. Some topsheets include a skin-care lotion, such as those found in diaper skin-care products, which can protect the skin from over hydration and reduce irritation. ​  Acquisition/Distribution Layer This layer is immediately under the topsheet of the diaper. It moves liquid away from the baby’s skin and distributes it more evenly across the entire diaper core for better absorbency.The...

Disposable diapers are made from common materials that have a long history of safe use in a variety of everyday consumer products. An average diaper weighs between 1.4 and 1.8 ounces and is primarily made of cellulose, polypropylene, polyethylene and a super absorbent polymer, as well as minor amounts of tapes, elastics and adhesive materials. Advances in each of these materials have enabled diapers to become lighter, thinner and more effective – with less of an impact on the environment. Since becoming broadly available in the 1960s, disposable diapers have gone through a number of changes in materials used or diaper construction to improve their performance, fit, and skin comfort. In recent years these advances have also reduced diapers’ environmental impact. Diaper Making Machine

Specific materials in modern disposable diapers are designed to control the main factors which cause diaper rash. ​ Materials Used in Diapers Material Where Used in Diapers Polypropylene (PP) Primarily used for the topsheet, the part of the diaper next to baby’s skin, tapes and fastening system Polyethylene (PE) Primarily used for the backsheet, the outer cover, tapes, and fastening systems Cellulose fluff pulp Absorbent core and core tissue Superabsorbent polymer Absorbent core Elastics Along leg opening and waist to improve fit. Adhesives Throughout the diaper to bond various other materials together Super absorbent Polymers Historically, diapers used fluff pulp, made of cellulose derived from wood, as the sole absorbent material in the core. Fluff pulp was good at absorbing wetness, but not good at keeping it away from the baby’s skin. It is also easily saturated, making it unable to absorb additional urine. Today, superabsorbent m...
