The paper is a carrier for writing and printing, and can also be used for other purposes such as packaging, sanitation and the like. The paper making process includes two modes, machine-making and manual, and the machine-making includes continuous paper making, diluting paper pulp with water to certain concentration, dewatering in the wire of the paper making machine to form wet paper sheet, pressing to dewater and stoving to form paper. Manually, the fibers dispersed and suspended in water are made into wet paper sheets by a frame with a bamboo curtain, a polyester net or a copper net, and the wet paper sheets are pressed, dehydrated and dried in the sun or dried to form paper. The greatest difference between the machine-made paper and the manual paper is that the manual paper is greatly superior to the machine-made paper in toughness and tension. However, because of the low efficiency of manual paper making and the large paper demand, machine-made paper making methods are common and have been developed.
At present, current machine-made paper need add fluorescent whitening agent in the paper pulp in order to reach good effect when making, and outside highlight can cause certain damage to user's eyes after the paper is made well to there is the inking when the user uses the pen to write, and the paper can not even absorption printing ink, and the quilt that is very easy quick after the water of meeting soaks.
