Description

<p>Recycled paper utilization has risen due to environmental protection. As a consequence, use of lower quality recycled paper is increasing year by year, and because of this, problems with machine runnability and finished-product paper quality are increasing. Adhesive materials that exist in recycled paper accumulated on the surface of papermaking system or fabrics and these deposits are one cause of problems in papermaking. Thus control of low material is essential.</p><p>In this presentation, we report on the development of a chemical agent which has a revolutionary effect on adhesives. We discovered that this chemical had three effects. At first, it detackified the adhesives. Secondly disperse them. Thirdly the dispersed adhesives are attached to the cellulose fibers. This means that adhesives are discharged from the wetend with celluloses. As a result, papermaking loss is reduced.</p><p>Given these results, this chemical agent can become an important solution for discharging adhesives to the outside of the machine.</p>
