Notes

Parts of a Diaper
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, connects the diaper onto the child, and creates a correct fit around the legs.
Diaper Core
The core is mostly composed of polypropylene, cellulose and a superabsorbent polymer.

Topsheet
The topsheet is the part of the diaper which can be found in contact with the baby's skin. It has been specifically designed to rapidly move fluids to the core while staying soft and dry to the touch. Some topsheets consist of a skin-care lotion, such as those discovered in diaper skin-care items, 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 far from the baby's skin and disperses it more equally across the entire diaper core for better absorbency.The most significant design enhancement was the advancement, in the 1980s, of superabsorbent polymers that can take in many times their weight in fluids. Children's skin health has improved since these polymers lock moisture away where it can not aggravate skin. The intensity and frequency of diaper rash has decreased significantly. As technology has enhanced, less and less cellulose has been required. This permits major decreases in diaper weight and volume, leading to a lowered environmental impact.
Absorbent Core
The absorbent core is the inner-most layer of the diaper. It normally includes a blend of cellulose fluff pulp and polyacrylate granules. The cellulose part rapidly takes in and transfers urine to the polyacrylate superabsorbent product, where it is caught. This keeps the baby's skin dry, even if she or he rests on a full diaper.
The most significant style enhancement was the development, in the 1980s, of superabsorbent polymers that can absorb from numerous tens to several hundred times their weight in fluids. Kid's skin health has enhanced since these polymers lock moisture away where it can not irritate skin. The intensity and frequency of diaper rash has actually decreased drastically. As technology has enhanced, less and less cellulose has actually been needed. This permits significant reductions in diaper weight and volume, resulting in a decreased environmental impact.

оборудование для производства подгузников is made up of the backsheet plus additional functions that guarantee the diaper fits well. Машина для гигиенических салфеток can consist of stretch side panels, attaching systems and tapes, and leg cuffs.

Backsheet
The backsheet is the water-resistant external layer of the diaper and it prevents liquids from going through the diaper and dripping onto the infant's clothing or surrounding environment. The polyethylene backsheet can be made with a structure that permits water vapor and air (but not liquids) to go through, minimizing wetness and keeping the skin drier.
Fit and Comfort Functions
Materials and particular styles that assist diapers fit well differ according to maker, but they all carry out the exact same standard functions. Important design elements frequently consist of stretch side panels and fastening systems that make it possible for the diaper to be pulled snug versus the child's upper body to prevent leaks leading. Elastics and cuffs on the diaper's sides make sure enhanced healthy around the legs and prevent leak.
Additional Materials
In both the diaper core and chassis, small amounts of adhesives are used to bond part together to guarantee efficiency, fit, and overall integrity. In some products, functions such as styles or fragrances may be included.
