Many people are familiar with products such as dust-free paper, dust-free wiping paper, and wiping paper. With the advancement of technology and the development of industrial technology, the production process of dust-free paper is also constantly improving. Then many people must not know much about the development history of clean paper, so I will introduce the development history of clean paper industry to you next.
In the 1960s, Europe took the lead in using natural fibers as raw materials to invent clean paper. Danish inventor Karl Kronya was the first to use wood pulp to design a dry forming technology, which was put into full-scale commercial production in North America and Europe in the early 1970s. The initial design method was to install a fixed screen as a former in a vacuum box and scatter the fibers downward. Through the action of the vacuum, the fibers fall onto the underlying forming wire, forming a shaped web. In the late 1970s, Finland's United Paper Mills and another company, MJ, respectively improved the dry-laid papermaking technology. The improved dust-free papermaking technology was more widely used in the 1980s.
In the early 1980s, in order to adapt to the production of clean paper, a colleague of Kronya, Johan Moskaert, replaced the fixed web former with the design of a rotary cylinder former. In the field of clean paper production technology very competitive. Kimberly-Clark, the second largest household paper in the United States, has also developed a paper towel suitable for commercial use, Kimberly-Clark WYPALLX60 all-purpose wipes. It is not easy to leave hair and dust after wiping. HYDROKNIT* patented technical material has high tear resistance and wear resistance, and has excellent water and oil absorption properties. In the mid-1980s, with the development of the chemical industry, especially the emergence of composite fibers, the Danish company DANKLON provided composite fibers as the goal, and designed the horizontal cylinder forming technology, which can use different lengths and different types of composite fibers to mix uniformly. Shaped into clean paper, wipe paper. Later, after continuous improvement, the rapid development of composite fiber technology has further improved the production efficiency of heat-sealed clean paper.
In the early 1990s, the Danish MJ company successively launched the forming mesh technology to meet the needs of using composite fibers to adapt to the production of dust-free wiping paper. At the same time, Nippon Paper Company has started to develop dry-laid technology since the 1960s. Through more than 20 years of efforts, it has developed a set of unique dry-laid Fourdrinier wire and rotary wire paper machines.
