Hot drawing method of high-strength and high-modulus vinylon filaments and implementation equipment

The invention discloses a hot drawing method of high-strength and high-modulus vinylon (PVA) filaments and implementation equipment. The hot drawing method comprises the technological processes that (1) tows in a spinning cake stripping cylinder pass through a first oiling system; (2) the tows are dried in a hot drawing roller set and subjected to hot drawing; (3) the tows pass through an interlacer and a second oiling system; and (4) a winding head is used for winding the tows into a filament tube. The equipment is mainly composed of a drafting rack, the spinning cake stripping cylinder, a panel, the first oiling system, hot drawing rollers, a gas path system, the interlacer, the second oiling system and the winding head. The drafting part, interlacing and winding operations are carried out on one layer. The invention provides the hot drawing method of the high-strength and high-modulus vinylon filaments and the implementation equipment which are convenient and fast, save resources and improve the production
