Platinum maxipad Disposable Although producers are generally reluctant to reveal the exact composition of their products, the main materials are usually bleached rayon (cellulose made from wood pulp), cotton and plastics. In addition, fragrance and antibacterial agents can be included. The plastic parts are the backsheet and polymer powder as an additional powerful absorbent (superabsorbent polymers) that turns into a gel when moistened. Procter & Gamble advertise a proprietary material called infinicel as the core of their napkins. In general, the layering is as follows: "an absorbent core material placed between a flexible liquid-pervious topsheet and a liquid-impervious plastic backsheet that has an adhesive on the outside for attaching the napkin to an undergarment". As is the case with disposable tampons and diapers, recycling is difficult and rarely done due to cost reasons, although proof-of-principle solutions appear to exist. When not dumped in a landfill where the non-biodegradable parts may persist for thousands of years, conventional hygiene products can at best be "thermally recycled" (incinerated). There are several different types of disposable<unk> s: * Panty liner: Designed to absorb daily vaginal discharge, light<unk>  flow, "spotting", slight urinary incontinence, or as a backup for tampon or<unk>  cup use. * Ultra-thin: A very compact (thin) pad, which may be as absorbent as a Regular or Maxi/Super pad but with less bulk. * Regular: A middle range absorbency pad. * Maxi/Super: A larger absorbency pad, useful for the start of the<unk>  cycle when<unk> ion is often heaviest. * Overnight: A longer pad to allow for more protection while the wearer is lying down, with an absorbency suitable for overnight use. * Maternity: These are usually slightly longer than a maxi/Super pad and are designed to be worn to absorb lochia (bleeding that occurs after childbirth) and also can absorb urine. The shape, absorbency and lengths may vary depending on manufacturer, but usually range from the short slender panty liner to the larger and longer overnight. Long pads are offered for extra protection or for larger women whose undergarments might not be completely protected by regular length pads, and also for overnight use. Other options are often offered in a manufacturer's line of pads, such as wings or tabs that wrap around the sides of underwear to add additional leak protection and help secure the pad in place. Deodorant is also added to some pads, which is designed to cover<unk>  odor with a light fragrance. There are even panty liners specifically designed to be worn with a thong/G-string. Reusable cloth<unk>  with Kokopelli motif. Reusable (cloth) Some women use a washable or reusable cloth<unk> . These are made from a number of types of fabric—most often cotton flannel, bamboo, or hemp (which is highly absorbent and not as bulky as cotton). Most styles have wings that secure around the underpants, but some are just held in place (without wings) between the body and the underpants. Some (particularly the older styles) are available in belted styles. Cloth<unk> s made a comeback around the 1970s, with their popularity increasing in the late 1980’s and early 1990’s. Reasons women choose to switch to cloth<unk> s include comfort, savings over time, environmental impact and health reasons. Washable<unk> s do not need to be disposed of after use and therefore offer a more economical alternative. Reusable<unk> s can be found on a number of websites, or are made at home (instructions are available online). They have become a popular alternative because they are allergen- and perfume-free, and can be more comfortable for women who suffer from irritation from using disposable pads. There are many styles of cloth<unk> s available today, ranging from panty liners to overnight pads. Popular styles of cloth<unk> s include all-in-one, or AIO pads, in which the absorbent layer is sewn inside the pad, "inserts on top" style pads, which have absorbent layers that can be secured on top of the pad as needed, envelope or pocket style pads, which have absorbent layers that can be inserted inside the pad as needed, and a foldable style, in which the pad folds around the absorbent layers. Cloth<unk> s can also have a waterproof lining, which provides more leak protection but may also be less breathable than those with no lining. Modern reusable cloth pads in differing sizes
