Embodiment Construction

[0010] A large-diameter polyether ether ketone monofilament, the polymer is polyetheretherketone or copolymerized modified polyetheretherketone, the diameter of the monofilament is 0.1~5mm, the strength of the monofilament is ≥3.5CN / dtex, and the elongation at break is 15~35%, dry heat shrinkage ≤2%, working temperature is 220~250℃.

[0011] The production method of the above-mentioned large-diameter polyetheretherketone monofilament is: including the steps of melt extrusion, cooling, stretching, and heat setting. The cooling adopts a liquid cooling method, and the polymer melt ejected from the spinneret assembly 1 is directly fed into In the liquid tank 2, the liquid is cooled and formed, and the liquid tank is transported out of the liquid tank through the front and rear winding rollers 3 and 4 in the liquid tank to enter the subsequent process; the front and rear winding rollers are located on the same level, and the front and rear winding rollers The distance between the r...

Abstract

The invention discloses a large-diameter polyether-ether-ketone monofilament and a production method thereof. Polymer is polyether-ether-ketone or copolymerization-modified polyether-ether-ketone, the diameter of the monofilament is 0.1mm to 5mm, the strength of the monofilament is greater than or equal to 3.5CN / dtex, the elongation at break is 15 to 35 percent, the dry-hot shrinkage rate is less than or equal to 2 percent, and the working temperature is 220 DEG C to 250 DEG C. The production method includes the steps of melt extrusion, cooling, drawing and thermoforming, and cooling adopts a liquid cooling method. The process is simple and convenient to operate, the formed fiber has the characteristics of high strength, high roundness, high uniformity and the like, and the application range is wide.
