<p>Provided is a method for preparing a spinning solution of ultra-high molecular weight polyethylene fiber, which comprises mixing a dissolved solution of ultra-high molecular weight polyethylene with a swollen solution of ultra-high molecular weight polyethylene at a weight ratio of 0.42~2.85, to obtain a spinning solution with a content of the ultra-high molecular weight polyethylene being 10%~15% by weight; the content of the ultra-high molecular weight polyethylene in the swollen solution of ultra-high molecular weight polyethylene is 10%~50% by weight; and the weight ratio of the ultra-high molecular weight polyethylene in the swollen solution of ultra-high molecular weight polyethylene to the ultra-high molecular weight polyethylene in the dissolved solution of ultra-high molecular weight polyethylene is 2.5~70. Since the dissolved solution functions to plasticize the swollen solution, the problem of high viscosity of the spinning solution is well addressed, thus ensuring that the spinning solution has a good fluidity and spinning continuity, and avoiding broken filament and filament breakage from occurring in the subsequent spinning process, so as to prepare ultra-high molecular weight polyethylene fiber with good performance.</p> |
