Disposable menstrual pads grew from Benjamin Franklin's invention designed to save soldiers with buckshot wounds, but appear to have been first commercially available from around 1888 with the Southall's pad. The first commercially available American disposable napkins were Lister's Towels created by Johnson & Johnson in 1896. Disposable pads had their start with nurses using their wood pulp bandages to catch their menstrual flow, creating a pad that was made from easily obtainable materials and inexpensive enough to throw away after use. Kotex's first advertisement for products made with this wood pulp (Cellucotton) appeared in 1921. Several of the first disposable pad manufacturers were also manufacturers of bandages, which could give an indication of what these products were like.

Until disposable sanitary pads were created, cloth or reusable pads were widely used to collect menstrual blood. Women often used a variety of home-made menstrual pads which they crafted from various fabrics, leftover scraps, grass, or other absorbent materials, to collect menstrual blood. Many probably used nothing at all. Even after disposable pads were commercially available, for several years they were too expensive for many women to afford. When they could be afforded, women were allowed to place money in a box so that they would not have to speak to the clerk and take a box of Kotex

 pads from the counter themselves. It took several years for disposable menstrual pads to become commonplace. However, they are now used nearly exclusively in most of the industrialized world.

The first of the disposable pads were generally in the form of a cotton wool or similar fibrous rectangle covered with an absorbent liner. The liner ends were extended front and back so as to fit through loops in a special girdle or belt worn beneath undergarments. This design was notorious for slipping either forward or back of the intended position.

Later an adhesive strip was placed on the bottom of the pad for attachment to the saddle of the panties, and this became a favoured method with women. The belted sanitary napkin quickly became unavailable after the mid-1980s.

The ergonomic design and materials used to make pads also changed through the 1980s to today. With earlier materials not being as absorbent and effective, and early pads being up to two centimetres thick, leaks were a major problem. Some variations introduced were quilting of the lining, adding "wings" and reducing the thickness of the pad by utilising products such as sphagnum

Sphagnum is a genus of between 151 and 350 species of mosses commonly called peat moss, due to its prevalence in peat bogs and mires. A distinction is made between sphagnum moss, the live moss growing on top of a peat bog on one hand, and sphagnum peat moss or sphagnum peat on the other, the...

 and polyacrylate superabsorbent gels derived from petroleum. The materials used to manufacture most pads are derived from the petroleum industry and forestry. The absorbent core, made from chlorine bleached wood pulp, could be reduced to make slimmer products with the addition of polyacrylate gels which sucks up the liquid quickly and holds it in a suspension under pressure. The remaining materials are mostly derived from the petroleum industry, the cover stock used is polypropylene

s made a comeback around the 1970s, with their popularity increasing in the late 80s and early 90s. Reasons women choose to switch to cloth menstrual pads include comfort, savings over time, environmental impact and health reasons.

There are many styles of cloth menstrual pads available today. Popular styles of cloth menstrual pads 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 menstrual pads can have waterproof lining, which provides more leak protection but may also be less breathable.

In underdeveloped countries, reusable or makeshift pads are still used to collect menstrual blood. Rags, soil, and mud are also reportedly used for collecting menstrual flow.

 can be found on a number of websites, or are made at home (instructions are available online). They have become a popular alternative and gaining in popularity among women, because they are allergen- and perfume-free, and can be more comfortable for women who suffer from irritations from using disposable pads.

Uses

Menstrual pads are worn to absorb menstrual discharge (and thereby protect clothing and furnishings). They are usually individually wrapped so they are easier and more discreet to carry in a purse or bag. This wrapper may be used to wrap the soiled pads before disposing of them in appropriate receptacles. Some women prefer to wrap the pads with toilet paper instead of (or as well as) using the wrapper. Menstrual pads (of any type) should not be flushed down the toilet, as they can cause blockages. In developed countries, public toilets almost always include a purpose-made receptacle in which to place soiled pads. In First Aid, they make excellent dressings for heavy bleeding if gauze is unavailable or inadequate due to their high absorbency.
