Making Paper Cuts to Save Trees
5.5Papermaking properties Papermakingis a complex process of producing paper from fibers of different origins, which involves the removal of water from an aqueous slurry consisting of fibers, fines, and other chemical additives on a machine wire by forming a wet mat. This mat is subsequently pres...
People tend to use trees for papermaking. But maybe electronics engineers are turning out on something else ? It turns out that two major building blocks of wood have a lot of electrical qualities, says Magna Berghen, a professor at Lethbrg UniversityHis team has been working to make parts...

The process of papermaking can be divided into two methods: hand-made papermaking and machine papermaking. Both methods have common steps: raw materials, pulp, filtering, and drying. The basic steps of hand-made papermaking are as follows:Raw material preparation: Obtain raw materials such as ...
21st European Symposium on Computer Aided Process Engineering 1Introduction Papermakingis a complex process in which paper is produced from pulp (wood), water, filler, and chemicals. The goal in papermaking is to produce paper having the specified quality while minimizing the costs. The process co...
Modern paper-making began in China about 2,000 years ago. This process produced paper from cloth, straw, wood or the bark of trees. The raw materials are struck over and over until they become loose. Then they are mixed with water. After the water has been removed, the flat, thin ...
This process produced paper from cloth, straw, wood or the bark of trees. The raw mate-rials are struck over and over until they become loose.Then they are mixed with water. After the water has been removed, the flat, thin form remaining is permit-ted to dry. This becomes a sheet of...
papermaking Papermaking is such an incredible craft. It's hard to imagine that we can turn trees into something so versatile and useful. I mean, you just cut down a tree, process it, and suddenly you have sheets of paper that can hold writing, drawings, even photos! You know, the ...
Sometimes this is scrap fiber from sawmills, but it mostly comes from trees cut specifically to make paper. A growing trend is to use a percentage of recycled paper or cloth. The common factor of all these materials is cellulose fibers, long strands of strong fiber found in all plants, ...
