Abstract

The invention provides a humidifying method of acetate fibre and a humidifying device of the acetate fibre. The humidifying device is additionally arranged before an acetate fibre ribbon is fed to a crimper for crimping operation in a production line, and the acetate fibre ribbon is humidified and warmed. Water vapour of which the pressure is 0.02-0.8Mpa is introduced into the humidifying device; the time of the acetate fibre ribbon passing through the humidifying device is 0.05-0.5 seconds, and the processed target temperature is 50-95 DEG C. The humidifying device is of a box structure and contains an upper part of a humidifying box, a lower part of the humidifying box, a ribbon operation chamber and a vapour chamber; an upper vapour jet orifice plate on the upper part of the humidifying box is inclined or arch-shaped; the position of a condensed water tank at the lower part of the humidifying box is lower than the vapour jet orifice plate; and the upper vapour jet orifice plate and the lower vapour jet orifice plate respectively comprise jet orifices, and a temperature detection device is also arranged in the ribbon operation chamber. According to the humidifying device of the acetate fibre disclosed by the invention, the strength of the acetate fibre ribbon is improved, the damage of the crimper to the ribbon is reduced, the flying of the ribbon is reduced, simultaneously the content of acetone in the ribbon is decreased, and subsequent processing load is lowered.

Description

technical field [0001] The invention relates to a production method and production equipment of acetate fiber, especially a humidification method and humidification equipment before the acetate ribbon enters into a crimping machine for crimping operation. Background technique [0002] The production process of cellulose diacetate tow (or cellulose acetate ribbon) for tobacco belongs to dry spinning, and the fiber ribbon after spinning or spinning and oiling is directly sent to the crimping machine for crimping, and finally drying. to make. The process of ribbon crimping is the process of friction and damage to the ribbon by the pressing plate and counter roller of the crimping machine. The strength of acetate fiber is low, and some monofilaments are easy to break or damage during crimping, resulting in flying flowers, which will adversely affect the production environment. [0003] A method for producing cellulose acetate disclosed in the specification of application patent...
