Comparison of Some Properties of Selected Non-Wood Plants and Wood Species and Unbleached Kraft Pulps from These Materials

ABSTRACT

The different properties of hemp stalks, hemp woody-core, and Miscanthus × giganteus stalks cultivated in Poland and physical properties of unbleached kraft pulps from these materials were compared with the ones of pulps from pine, birch and wheat straw. Research performed showed that in terms of oven-dried material density, bulk density, yield, morphological, structural, and strength properties of pulps, hemp stalks and Miscanthus stalks are more similar to birch and pine than hemp woody-core and wheat straw. Thus, it can be stated that hemp and Miscanthus stalks should be better papermaking fibrous raw materials than hemp woody-core and wheat straw and could be used for the production of a broader range of papers and boards.

摘要

比较了波兰栽培的大麻秆、大麻木芯和Miscanthus × giganteus秆的不同性质，以及未漂白硫酸盐浆与松木、桦木和麦草浆的物理性质研究表明，与麻芯和麦秸相比，麻秸和Miscanthus秸在物料密度、容重、产量、形态、结构和强度等方面与桦树和松树更为相似因此，可以说，大麻和Miscanthus秸秆应该是比大麻木本芯和麦秸更好的造纸纤维原料，可以用于生产更广泛的纸和纸板.
