Abstract

In this study, the usability of okra (Abelmoschus esculentus) stalks in pulp and paper production was investigated. Firstly, chemical components and fiber morphological properties were determined to investigate the suitability of okra stalks for pulp and paper production. Holocellulose, cellulose and lignin contents were found as 76.1 %, 46.4 % and 16.0 %, respectively and the fiber length, fiber width and cell wall thickness were measured as 0.64 mm, 16.97 μm and 3.66 μm, respectively. According to these data, it has been determined that okra stalks are suitable for pulp and paper production. Four different cooking experiments were carried out by adding sodium borohydride (NaBH4) in different proportions (0 %, 0.3 %, 0.5 %, 0.7 %) to okra stalks by the alkali sulfite method. The yield, chemical, physical and optical properties of the pulps were determined and optimum properties were obtained from the cooking experiment by adding up to 0.7 % NaBH4 into cooking liquor. With the addition of 0.7 % NaBH4, pulp yield, breaking length, and burst index increased about 7.73 %, 3.84 %, and 11 %, respectively. Consequently, it has been concluded that pulp produced from okra stalks can be used in the paper industry by blending with long or recycled fibers in certain proportions.Ključne riječi

秋葵（Abelmoschus esculentus）茎制浆造纸性能的表征

在本研究中，研究了秋葵茎在纸浆和纸张生产中的可用性。首先，对秋葵秸秆的化学成分和纤维形态特性进行了测定，以考察秋葵秸秆对制浆造纸的适应性。全细胞、纤维素和木质素含量分别为76.1%、46.4%和16.0%，纤维长度、纤维宽度和细胞壁厚度分别为0.64mm、16.97μm和3.66μm。根据这些数据，已经确定秋葵茎适合用于纸浆和纸张生产。采用碱性亚硫酸盐法在秋葵茎中加入不同比例（0%、0.3%、0.5%、0.7%）的硼氢化钠（NaBH4），进行了四种不同的蒸煮实验。测定了纸浆的产率、化学、物理和光学性能，并通过在蒸煮液中加入0.7%的NaBH4进行蒸煮实验，获得了最佳性能。添加0.7%的NaBH4后，出浆率、破断长度和爆裂指数分别提高了7.73%、3.84%和11%。因此，已经得出结论，由秋葵茎生产的纸浆可以通过与长纤维或再生纤维按一定比例共混而用于造纸工业。Ključne riječi
