Spinning method of high-strength and high-modulus vinylon (PVA) filaments and implementation equipment

The invention discloses a spinning method of high-strength and high-modulus vinylon (PVA) filaments and implementation equipment. The spinning method comprises the following steps of (1) metering a spinning solution, wherein metering is carried out through a metering pump 2; (2) conducting filtering, specifically, adopting a candle-shaped filter 1; (3) conducting spinning, specifically, adopting awet vertical spinning method; (4) conducting solidification, specifically, enabling a fine liquid column sprayed from a spinneret cap 3 to quickly react with solidification liquid when passing through the solidification bath liquid in a vertical solidification pipe 4, so that the liquid column is solidified into silk, and the silk flock direction moves from bottom to top and is consistent with the flowing direction of the bath liquid; (5) conducting pre-drafting, specifically, enabling axes of pre-drafting rollers 5 and axes of pre-drafting rollers 6 to be parallel, and enabling the pre-drafting rollers 5 and the pre
