摘要（英）：

This invention relates to a water-absorption fiber and its manufacturing method. The formula of the fiber mass ratio is: polymer monomer: 75-85%, polymer blend: 15-25%, potential crosslinker: 0.1~15%, potential crosslinker: 0.1~15% that of the polymer monomer, initiator: 0.1~1.0% that of the polymer monomer, among which, the polymer monomer is acroleic acid, sodium acroleic acid or acrylamide, the polymer blend is PVA, the potential cross linker is propyl acrylate, proply hydrocarbon methacrylate ethyl acrylate hydrocarbon, ethyl methacrylate hydrocarbon or N-hydrocarbon methylacrylamide.The initiator belongs to super-sulphate oxidation system, or the oxidation-recovery system composed of super-sulphate and sulfite. The method includes: 1, applying one step solution polymerization method to prepare the solution directly, 2, taking it as the spinning solution to be vacuum defoamed, 3, applying a solution-dry method to spin fiber, 4, hot-crosslinking the fiber.
