    • PURPOSE: Provided are a method and apparatus for manufacturing nonwoven fabrics and, in particular, geotextiles. Nonwoven geotextiles are sheet materials which are constructed from synthetic fibres, made of polypropylene and/or other synthetic materials, and are employed in civil engineering applications, such as land drainage, filtration and reinforcement. CONSTITUTION: A method of manufacturing a nonwoven fabric, comprises: opening and mixing different input fibres to form a uniform fiber mixture having predetermined proportions of the different input fibres; carding the fiber mixture to form a uniform web of predetermined thickness travelling in a first direction; laying onto the web high tenacity yarns which extend in the first direction and are spaced apart transversely of the first direction; depositing fixed lengths of the web in alternating fashion on a conveyor travelling in a second direction transverse to the first direction to form on the conveyor a mat consisting of overlapping lengths of the web; and needle-punching the mat to form the nonwoven fabric.
    • 目的:提供一种制造无纺织物,特别是土工织物的方法和装置。 无纺布土工织物是由聚丙烯和/或其他合成材料制成的合成纤维构成的片材,用于土木工程应用中,例如排水,过滤和增强。 构成:制造无纺织物的方法包括:打开和混合不同的输入纤维以形成具有预定比例的不同输入纤维的均匀纤维混合物; 梳理纤维混合物以形成沿第一方向行进的预定厚度的均匀网; 铺设在沿第一方向延伸并沿第一方向横向隔开的网状物上的高强度纱线; 以交替方式将固定长度的纤维网沉积在沿与第一方向横向的第二方向上行进的输送机上,以在输送机上形成由网的重叠长度组成的垫; 并对垫进行针刺以形成无纺织物。
