Abstract (en)
[origin: EP2746434A1] A high-strength, high-modulus and high-melting point PVA fiber is a PVA fiber, manufactured by using a boron-containing gel-wet spinning method, having the strength greater than or equal to 13.5 CN/dtex, the modulus greater than or equal to 320 CN/dtex, the initial melting point greater than or equal to 108°C, the total stretching multiple up to 13.0¼14.5 times . The product has excellent performance and wide application range and is appropriate for the field of high-end industries. Also disclosed is a method for manufacturing the fiber.
