水刺工艺对竹浆纤维原纤化性能的影响

Effect of spunlace process on fibrillation of bamboo pulp fiber

为了解水刺加工过程中加工工艺对竹浆纤维原纤化性能的影响,实验采用3种不同线密度的竹浆纤维,在水压、水刺头数量、水刺距离、生产速度等工艺改变的情况下,通过测定竹浆纤维产品的原纤化指数,研究加工工艺和竹浆纤维原纤化的关系。实验结果表明:随着纤维线密度的增加,纤维的原纤化程度增加;在线密度相同的条件下,随着水刺压力的增加,纤维原纤化呈上升趋势;随着水刺距离和生产速度的增加,产品的原纤化呈下降趋势;水刺头的数量对竹浆纤维的原纤化影响不是很明显。

Three kinds of bamboo pulp fibers with different linear densities were selected to understand the relation between fibrillation of bamboo pulp fiber and spunlace process,fibrillation index was measured under different water pressure,number of spunlace head,spunlace distance and production speed.Results indicated that fibrillating of bamboo pulp fiber increased with increasing linear density.Under the same linear density,fibrillating of the fiber showed upward trend with increasing water pressure but showed downward trend with increasing spunlace distance and production speed.The number of spunlace head had no obvious effects on fibrillation of bamboo pulp fiber.
