Effects of stroke frequency, depth of needle penetration and mass per unit area on properties of needle-punched nonwoven fabrics produced from polypropylene (PP), 50/50 PP/kenaf and kenaf fibres have been studied. Properties of fabrics, such as tensile strength, puncture resistance, pore size, water permeability and transmissivity are analysed. Results obtained show that the higher tensile strength and puncture resistance are achieved in fabrics produced from kenaf fibres at higher stroke frequency, depth of needle penetration and mass per unit area. Fabrics produced from kenaf fibres can be employed in geotextile applications, since they also possess bigger pore size and higher water permeability.

工艺参数对聚丙烯和洋麻纤维针刺非织造土工织物性能的影响

研究了冲程频率，针刺深度和单位面积质量对聚丙烯（PP），50/50 PP /洋麻和洋麻纤维生产的针刺无纺布性能的影响。分析了织物的性能，例如抗张强度，抗穿刺性，孔径，透水性和透射率。所得结果表明，由洋麻纤维制成的织物在较高的冲程频率，针刺深度和单位面积质量下具有较高的拉伸强度和抗穿刺性。用洋麻纤维制成的织物可用于土工织物，因为它们也具有较大的孔径和较高的透水性。
