Paper Products

Paper-Products include various items like: Sanitary napkins, Tissue papers, Toilet paper-roll, Baby Diapers, paper Cups, etc. ProjectEhsan is initially aiming to produce baby diapers in Bangladesh with raw materials imported from overseas.
The need for diapers has always existed.  In America there were many old civilizations that used them; the Incas, the Aztecs, Native Americans and even the Innuits in Alaska used some primitive version of a diaper.  There are also a few references about the use of diaper predecessors in Europe and Asia.  Mass production of cloth diapers started by mid 19th century;  mass production of disposable diapers officially started until 1961 that is only 44 years ago when P&G started the disposable diaper business.  Of course we have all heard about the great contribution of Vic Mills, however even when it is much less known, it is important to also mention PauliStróm (the company from Sweden), Marion Donovan (the housewife inventor), Stanly Mason (another inventor), Billy Gene Harper and Carlyle Harmon (from the Dow and the J&J companies), and many others, all of which have contributed to the development of the modern disposable diaper.  A lot has happened since 1961; however I believe the most important events in the evolution of the disposable diapers were:

1.Introduction of the fastening system integrated with the diaper, 1970
2.The use of fluff instead of creped Tissue, 1972
3.The use of Superabsorbent polymer, 1986
4.The use of Frontal Tape and Hook and Loop systems, 1987
5.The addition of leg cuffs anti-leak barriers, 1989
6.The introduction of cloth-like back sheets, 1994
7.The training pant diaper for larger babies, 1994

Bangladesh will likely become a very good market for baby diapers.
Disposable diapers are produced in a continuous process.  A baby diaper machine is typically between 20 to 45 meters long, depending on the speed and the complexity of the product to be made.  When we take into account the primary peripheral equipment, a typical machine will be from 6 to 13 meters in width. Typical diaper machine speeds range between 200 to 600 diapers per minute, though some of the larger companies have machines running at 1,000 pieces per minute.  The fastest machine I have personally seen was running at 950 diapers per minute. The process starts at the mill, where a sheet of pulp is fed into a rotary mill and is converted into fibers (from 2.3 to 2.7 mm in length). These fibers are transported into a forming pocket using a vacuum generator that is also called the “dust collector”.   As the fibers are produced, they are mixed with a super-absorbent within the drum former.  The drum former usually holds between 8 to 12 pockets, depending on diaper size and the diameter of the drum.  The mix of pulp and powder coming out from the drum is called “the pad” or “the absorbent core”.  Once the pad is formed, a layer of tissue (or light weight non-woven) is placed on the top, bottom or around the whole pad.   The pad is then compressed using a debulker roll and then it is cut into individual pieces of pad (unless the pad was made in a non continues drum former). In the next step, a poly film or cloth-like material is added at the bottom of the pad (or laminated on line) and non-woven material is added at the top.
