Abelmoschus esculentus okra as whole stalks was examined for its suitability for pulp and paper production. It’s, fiber dimensions, morphological and chemical characteristics were reported. The pulping trials with soda- Anthraquinone (AQ,) at different chemical charges. Application of 21% as NaOH with 0.1% AQ gave good results in degree of delignification, mechanical properties. Utilization of okra pulps and blender is recommended due to good pulp properties. Evaluation of general characteristics of okra stalks in terms of fiber dimensions morphological indices, chemical components, Soda-AQ cooking and to study their suitability for paper production. Okra Fiber dimension evaluation done after maceration with a mixture of 30% hydrogen peroxide and acetic acid (1:1) for core and bark parts separately and was carried out under microscope staining with aqueous safranin. The Soda-AQ cooks at different active alkali levels were calculated as NaOH on oven dry raw material. The fibers from okra stalks studied (core and bark) were in the range of hardwood fibers, with short fiber length, especially the core with more or less moderate walls, narrow lumen and fiber width. The fiber width of bark was medium –narrow with medium wall thickness. The ash content was rather high whereas the silica content was comparatively high The hot water extractives from okra stalks was (4.1%), cold water (0.4) ethanol/ cyclohexane (1.1), ethanol extractives (1.2%) and 1% NaOH (27.6%) were rather high. The cellulose (Kurschner-Hoffer) was (48.5%) The lignin content was (15.3%) which was relatively moderate. The use of 0.1% AQ enhanced the delignification in the three trials applied. The screened yield increase with increase of chemical dose applied while the rejects decrease. When 21% NaOH was applied, the screened yield was 32.2% with negligible amount of rejects, however with lower alkali charge 18% the screened yield was decreased to 28% with very low rejects 1.5%. on the other hand rejects were increased to 7% when 15% NaOH was applied with very low screened yield 19%.The pulps produced from okra soda-AQ are suitable for production of printing and writing papers and it is advisable to use them in blending due to good papermaking properties.

苏打-AQ制浆在苏丹农业废料（秋葵茎）中的应用

检查了作为整个茎的黄秋葵（Abelmoschus esculentus秋葵）是否适合制浆和造纸。报告了纤维的尺寸，形态和化学特性。用苏打蒽醌（AQ，）在不同化学剂量下进行制浆试验。添加21％的NaOH和0.1％的AQ可以在脱木素度和机械性能方面取得良好的效果。由于良好的纸浆性能，建议使用秋葵纸浆和搅拌机。根据纤维尺寸形态指标，化学成分，苏打-AQ蒸煮评估秋葵茎的一般特性，并研究其在造纸中的适用性。在浸渍30％过氧化氢和乙酸的混合物（1：1）分别取芯和树皮部分，并在显微镜下用番红花水进行染色。将不同活性碱含量的Soda-AQ蒸煮炉以干燥的干燥原料上的NaOH计算。所研究的秋葵茎的纤维（芯和树皮）属于硬木纤维范围，纤维长度短，尤其是具有或多或少中等壁，内腔狭窄和纤维宽度的芯。树皮纤维宽度中等，壁厚中等。灰分含量较高，而二氧化硅含量较高。秋葵茎的热水提取物为（4.1％），冷水（0.4）乙醇/环己烷（1.1），乙醇提取物（1.2％）和1％NaOH（27.6） ％）很高。纤维素（Kurschner-Hoffer）为（48.5％）木质素含量为（15.3％），这是相对中等的。使用0。在所应用的三个试验中，1％的AQ增强了去木质素作用。筛选出的产量随着所施用化学剂量的增加而增加，而次品减少。当使用21％的NaOH时，筛渣的收率为32.2％，而渣浆的量可忽略不计，但是，在碱含量为18％的情况下，筛渣的收率降至28％，筛渣的极低值为1.5％。另一方面，当使用15％的NaOH（筛分产率很低）时，废品率提高到7％。从秋葵苏打-AQ生产的纸浆适用于印刷和书写纸的生产，建议将它们混合使用由于具有良好的造纸性能。2％的废品量可忽略不计，但是，当碱含量低至18％时，筛选出的收率降低至28％，而废品率极低（1.5％）。另一方面，当使用15％的NaOH（筛分产率很低）时，废品率提高到7％。从秋葵苏打-AQ生产的纸浆适用于印刷和书写纸的生产，建议将它们混合使用由于具有良好的造纸性能。2％的废品量可忽略不计，但是，当碱含量低至18％时，筛选出的收率降低至28％，而废品率极低（1.5％）。另一方面，当使用15％的NaOH（筛分产率仅为19％）时，废品率提高到7％。由秋葵苏打-AQ生产的纸浆适用于印刷和书写纸的生产，建议将它们混合使用由于具有良好的造纸性能。
