摘要:采用扫描电子显微镜、光学显微镜、纤维形态分析仪等手段分析了羽毛纤维的形态，并比较了羽毛纤维和木浆纤维的形态差异，同时研究了抄纸时添加羽毛纤维对纸张性能的影响。结果表明，来自白羽鸡不同部位的羽毛纤维在形态上差异较大，羽枝纤维的平均长度为15~20 mm，平均宽度为30~35 μm，而绒枝纤维的平均长度为20~25 mm，平均宽度为20 μm左右；经化学机械法分离后羽毛纤维长度和阔叶木浆纤维相差不大，宽度介于针叶木浆纤维和阔叶木浆纤维之间，扭结指数较木浆纤维小。打浆处理羽毛纤维对纸张的各项性能影响不大。添加羽毛纤维影响纸张性能，随着羽毛纤维用量的增加，纸张的松厚度升高，但裂断长、耐破指数和撕裂指数均下降。

Abstract:The morphology of feather fiber was analyzed using scanning electron microscope, optical microscope and fiber morphology analyzer in this paper, and the influence of feather fibers mixed with wood pulp fibers on paper properties was investigated. The results indicated that the morphology of feather fibers from different parts of white chicken was different greatly, average length of feather barb was 15~20 mm and average width was 30~35 μm, average length of down-silk was 20~25 mm and average width was 20 μm. After separating with chemi-mechanical method, the feather fibers length was reduced similarly to hardwood fiber, the width was between softwood and hardwood fibers, and kink index was lower than wood fiber. The addition of feather fibers to paper sheets had a great influence on properties of paper sheets, breaking length, burst index and tear index decreased, but the bulky property increased with increasing addition amount of feather fibers. The Refining of feather fiber could not apparently improve physical properties of paper sheets, it was different from wood fibers.
