摘　　要：对影响纸质方便筷强度的主要因素进行了研究。结果表明 ,纸质方便筷的强度随紧度的提高而提高 ,而纸张纤维的长度则影响较小。干强剂淀粉和湿强剂脲醛树脂的加入量分别为 10 %和2 % (对浆 )时 ,可获得最佳的增强效果。矾土的加入对增强剂的增强有促进作用 ,加入量为 2 % (对淀粉 )即可。This paper reports the study on the factors affecting the strength of paper chopstick. It is concluded that the strength of the paper chopstick improves with increase of tightness of the paper while its fiber length affects slightly. Optimum effects can be achieved by adding dry strengthening starch agent and wet strengthening UF resins agent, with starch 10% and UF resins?2% on dry pulp. Adding Al 2(SO 4) 3,with 2% on starch, can improve the effect of the strengthening agent.
