The Washingtonia palm (Arecaceae) is a fast-growing species. Their management generates a large amount of biomass each year, which is generally disposed of in landfills or burned on-site without being valorized. In this work, the petiole part of Washingtonia palm was introduced in the automotive industry for interior applications through the production of soft feel eco-friendly bio-composite nonwovens made of Palm, Wool, and Polyester fibers through a needle-punching process. Initially, palm microfibrils were extracted in a solution containing sodium hydroxide (NaOH) and hydrogen peroxide (H₂O₂) at concentrations equal to 0.70 %. Subsequently, composite nonwovens were manufactured from the Palm/ Wool (P/W) and Palm/ Polyester (P/PES) blends with a weight proportion of 3/1. Afterwards, nonwovens were coated with different percentages of WPU (2.5, 5, 10, 15, and 20 wt%), dried at 120 °C and hot calendered between two rolls at 20 K N pressure and 140 °C temperature. Developed nonwovens were tested for physical, morphological, mechanical, climatic, and abrasion resistance performance. The findings revealed that Washingtonia palm-based biocomposite nonwovens treated with WPU proportions equal to/or higher than 10 wt% had excellent tensile strength and abrasion resistance. The climate aging test, on the other hand, confirmed their durability. The FTIR and SEM data indicated that WPU polymer adheres well to P/W and P/PES nonwovens. Furthermore, they provide aesthetically pleasing fabrics with a golden color appearance, low raw material costs, and environmental benefits, suggesting that they could be a suitable candidate for automotive interior applications.

该丝葵属棕榈（棕榈科）是一家快速成长的品种。他们的管理每年都会产生大量的生物质，这些生物质通常被丢弃在垃圾填埋场或就地焚烧而没有被评估。在这项工作中，通过针刺工艺生产由棕榈、羊毛和聚酯纤维制成的手感柔软的环保生物复合非织造布，将华盛顿棕榈的叶柄部分引入汽车行业，用于内饰应用。最初，在含有氢氧化钠（NaOH）和过氧化氢（H ₂ O ₂）的溶液中提取棕榈微纤维。) 浓度等于 0.70 %。随后，复合非织造布由重量比为 3/1 的棕榈/羊毛 (P/W) 和棕榈/聚酯 (P/PES) 混合物制成。然后，非织造布涂上不同百分比的 WPU（2.5、5、10、15 和 20 wt%），在 120 °C 下干燥，并在两个辊之间在 20 K N 压力和 140 °C 温度下进行热压延。开发的非织造布经过物理、形态、机械、气候和耐磨性能测试。调查结果显示，华盛顿用等于/或高于 10 wt% 的 WPU 比例处理的棕榈基生物复合非织造布具有优异的拉伸强度和耐磨性。另一方面，气候老化测试证实了它们的耐用性。FTIR 和 SEM 数据表明 WPU 聚合物与 P/W 和 P/PES 非织造布的粘附性良好。此外，它们提供具有金色外观、低原材料成本和环境效益的美观织物，表明它们可能是汽车内饰应用的合适候选者。
