Abstract
The invention provides a production method of a nylon-66 high-strength yarn. The production method comprises the following step of: processing a nylon-66 saline solution, which is taken as a raw material, by a concentration tank, a reactor, a pressure reducer, a front polymerizer, a back polymerizer, a spinning yarn conveying pump, a spinning box used for spinning, a draw machine used for drawing and a winding machine used for winding in sequence, wherein the mass concentration of the concentration tank is 770g/L; the temperature of the reactor is 255 DEG C; the temperature of the spinning box is 313 DEG C; and the draw ratio is 5.54. The production method of the nylon-66 high-strength yarn, disclosed by the invention, has the following technical effect that a produced nylon-66 high-strength yarn product is stable in quality, fewer in fuzziness and yarn breakage phenomena, good in spinnability and low in production cost.
Description
Technical field
The present invention relates to a kind of production method of polyamide fibre 66 high strength yarns, belong to the chemical fibre technical field.
Background technology
Polyamide fibre 66 high strength yarns are the very big chemical fibre raw materials of a kind of market potential, have intensity height, fatigue durability is good, DIMENSIONAL STABILITY is good, dry-hot shrinkage is low advantage, can be used as the framework material of tire.
The polyamide fibre 66 high strength yarn unstable product quality that the production method of existing polyamide fibre 66 high strength yarns is produced, indexs such as intensity, percentage elongation, dry-hot shrinkage are undesirable.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, a kind of production method of polyamide fibre 66 high strength yarns is provided.
The production method of polyamide fibre 66 high strength yarns of the present invention, may further comprise the steps: be raw material with polyamide fibre 66 saline solutions, process thickener, reactor, pressure reducer, pre-polymerization device, back polymerizer, spinning delivery pump, manifold are carried out spinning successively, drawing machine carries out drawing-off and up-coiler is reeled
Said thickener mass concentration is 770g/L.
Said temperature of reactor is 255 degrees centigrade.
Said condition of spinning manifold temperature is 313 degrees centigrade.
Said draw ratio is 5.54.
The production method of polyamide fibre 66 high strength yarns of the present invention has following technique effect: the polyamide fibre 66 high strength yarn constant product quality of producing, and lousiness and fracture of wire phenomenon are less, good spinnability, production cost is low.
