Because of palm leaf fiber has long fiber length, high breaking strength, it has great value in de?velopment and utilization. The process of chemical degumming on palm leaf fiber was researched. The dosage of sodium hydroxide (NaOH) and sodium sulphide (Na2S) to chemical degumming effect was discussed, and the degumming palm leaf fiber was modified with urea and emulsified with amino silicone oil. The result indi?cated that the palm leaf fiber′s breaking strength was 146 cN, linear density 1.44 tex, softness 202 twist/20 cm when NaOH 8%(omf, the same below), Na2S 5%, JFC 2%, 100 ℃, 90 min, bath ratio 1:10. The fiber fine?ness increased 31.9%, and the breaking strength only decreased 5.68% after urea modification. The softness of palm leaf fiber was 228 twist/20 cm after soft treated with amino silicone oil. Which provided certain basis for the subsequent development of palm leaf fiber.%棕叶纤维因纤维长度长、断裂强度高等优良特性,具有很好的开发利用价值.通过对棕叶纤维进行化学脱胶,探讨了氢氧化钠(NaOH)用量、硫化钠(Na2S)用量对脱胶效果的影响,并对脱胶后的棕叶纤维进行尿素改性和氨基硅油乳化处理.结果表明:在NaOH用量8%(omf,下同)、Na2S用量5%、渗透剂JFC用量2%、100℃、90 min、浴比1:10的工艺条件下,棕叶纤维的断裂强力为146 cN,线密度为1.44 tex,柔软度为202捻/20 cm;尿素改性后,纤维细度提升了31.9%,断裂强力仅降低5.68%;氨基硅油乳液柔软处理后,棕叶纤维柔软度为228捻/20 cm,为棕叶纤维的后续开发提供了一定的基础.
