Polymers in diapers / Feminine hygiene pads

[Guest guest]

You don't even want to know what's in disposable diapers. I have a feeling, this is what they did to our feminine hygiene pads also, as they make them flat now instead of it being cotton.........the chemicals do all the work Nonwovens are typically made from plastic resins, such as nylon, polyester, polyethylene, or polypropylene, and are assembled by mechanically, chemically, or thermally interlocking the plastic fibers. There are two primary methods of assembling nonwovens, the wet laid process and the dry laid process. A dry laid process, such as the "meltblown" method, is typically used to make nonwoven diaper fabrics. In this

method the plastic resin is melted and extruded, or forced, through tiny holes by air pressure. As the air-blown stream of fibers cools, the fibers condense onto a sheet. Heated rollers are then used to flatten the fibers and bond them together. Polypropylene is typically the material used for the permeable top sheet, while polyethylene is the resin of choice for the non-permeable back sheet.Read more: How disposable diaper is made - material, manufacture, used, parts, components, product, industry, Raw Materials, The Manufacturing Process, Byproducts/Waste, Quality

These polymeric particles act as tiny sponges that retain many times their weight in water. Microscopically these polymer molecules resemble long chains or

ropes. Portions of these chemical "ropes" are designed to interact with water molecules.Read more: How disposable diaper is made - material, manufacture, used, parts, components, product, industry, Raw Materials, The Manufacturing Process, Byproducts/Waste, Quality Control http://www.madehow.com/Volume-3/Disposable-Diaper.html#b#ixzz1xD4Tk2Af
