Silane-treated natural cellulosic Kigelia africana fruit fibre (KAF) was experimentally established to have strong strength after removing hydrophilic materials. Silane treatment makes it compatible with hydrophobic biopolymeric materials than existing non-grafted KA fibre. In this work, the polysaccharide was extracted from the KAF and found to have all the essential compounds. KA fruit-based cellulosic fibre was extracted and treated with different concentrations of silane solution. Silane-treated (13%) KAF has a cellulose content of about 76.86%. The peak found at 1734 cm shows the hemicellulose in untreated fibres, and its intensity decreased after silane treatment, as confirmed by FTIR. X-ray diffraction investigation indicated that silane-treated (5%) KAF has a crystallinity index of 70.22%. After treatment, the tensile strength of 5% silane-treated KAF shows a tensile strength of 490.77 MPa, giving more viability to biofibre reinforcement.
经实验证实，硅烷处理过的天然纤维素非洲吊灯树果实纤维（KAF）在去除亲水性物质后具有很强的强度。与现有的未接枝KA纤维相比，硅烷处理使其与疏水性生物聚合材料具有更好的相容性。在这项工作中，从KAF中提取了多糖，发现其含有所有必需的化合物。提取了基于KA果实的纤维素纤维，并用不同浓度的硅烷溶液进行处理。经硅烷处理（13%）的KAF的纤维素含量约为76.86%。在1734 cm处发现的峰表明未处理纤维中的半纤维素，经傅里叶变换红外光谱（FTIR）证实，硅烷处理后其强度降低。X射线衍射研究表明，经硅烷处理（5%）的KAF的结晶度指数为70.22%。处理后，5%硅烷处理的KAF的拉伸强度为490.77 MPa，使生物纤维增强具有更大的可行性。
