【 摘 要 】

The bamboo fibre is a new kind of natural fibre from bamboo with machine method, and is in the frontier of bamboo timber processing, new composite and textile research field. The combing method is mainly one in processing bamboo fiber. The plasticity and strength of bamboo were required in processing bamboo fiber by machine method. The aim of this work is to explore changes of mechanical properties -lengthways tensile properties of bamboo after alkali treatment and focuses on a relation between lengthways tensile properties of alkali treated bamboo and the moisture content. Mechanism of plastic deformation of bamboo was initially revealed in this paper. Experiment shows that: above fibre saturation point, the lengthways tensile strength and elasticity modulus of bamboo decreased with increase of moisture content with 2.5%NaOH soaking for 24h, and bamboo plasticity is better when its moisture content is between 40% and 90%. According to the principle of bamboo fiber processing by combing, the moisture content of bamboo should be controlled from 50% to 70% after 24h soaked with 2.5%NaOH. Bamboo fiber processing test shows that the conclusion is correct.
