研究了竹浆纤维的循环再利用及超声波处理对竹浆纤维和纸张特性的影响；评价了竹浆纸张的密度、抗张强度等特性，探讨了单纤维强度和纸张纤维间结合力的关系。结果表明，竹浆纸张的密度和抗张强度随着循环再利用次数的增加而降低，超声波处理纸浆纤维提高了纸张的抗张强度。Page理论表明，纸张抗张强度的提高主要是由于超声波处理增强了纸张内部的纤维间结合力。光学显微镜结果显示，超声波处理通过切断纤维、润胀纤维、细纤维化纤维的作用，有效改善了纸张的强度。研究表明，纸张的循环再利用会降低竹浆的保水值，而利用超声波处理可以有效提高纸浆的保水性能，改善纸张的抗张强度。

The recycling and the ultrasonic treatment of bamboo fibers are investigated. And the bamboo paper density, the tensile strength and other properties of the handsheets are determined. Repeated recycling leads to a decrease of the paper density and the tensile strength. The Page equation(1/T =1/F +1/B ) is used to evaluate the strength contributions of a single fiber and the inter-fiber bond to the tensile strength of the bamboo handsheet. It is found that the bamboo paper strength improves as a result of the ultrasonic treatment, which is essentially due to the enhanced inter-fiber bonding strength and the slight changes of the zero-span tensile strength. Optical microscopic observations indicate that, the ultrasonic treatment has induced the fiber cutting, the fiber swelling, and the fibrillation, which contributes to the bamboo paper strength improvement. The WRV(Water retention value) depends upon the times that the fibers are recycled, and the repeated recycling leads to a reduction of the bamboo pulp WRV. Interestingly, the ultrasonic treatment significantly enhances the water retention, as well consistent with the results related to the bamboo paper strength.
