摘要： A multiaxial laminated non-woven fabric is comprised of tows used as a constituent material and overlaid and bonded with one another. The starting material tow has crimps and has total tex of not more than 300,000 and tow-constituting filaments have an average fineness of not more than 3 tex. A three-dimensional moulded products from the multiaxial non-woven fabric is also provided, and a method for stably producing the non-woven tow fabric while ensuring quality comprises subjecting tows multiaxially and obliquely overlaid with one another to bonding treatment, such as needle punching, or heat treatment while they are held by pins of an overlaying machine.
