Embodiment Construction

[0010] A high-strength wear-resistant nano-modified polyamide monofilament, the polymer is polyamide, nano-titanium dioxide, nano-silicon carbide or nano-alumina is added to the polyamide, and the content of nano-titanium dioxide, nano-silicon carbide or nano-alumina is 0.5~1.5wt%, monofilament diameter 0.08~5mm, monofilament strength ≥3.0CN / dtex, elongation at break 15~35%.

[0011] The production method of the high-strength wear-resistant nano-modified polyamide monofilament includes the steps of blending spinning, cooling, stretching, and heat setting. The spinning temperature is 240-275°C; The polymer melt ejected from the wire plate assembly 1 directly enters the liquid tank 2 for liquid cooling and forming, and is transported out of the liquid tank through the front and rear winding rollers in the liquid tank to enter the subsequent process; the front and rear winding rollers 3 and 4 are located on the same horizontal plane, the distance between the front and rear windin...

Abstract

The invention discloses a high-strength wear-resistant nano-modified polyamide monofilament and a production method thereof. The polyamide monofilament is characterized in that the polymer is polyamide; 0.5-1.5wt% of nano titania, nano silicon carbide or nano alumina is added into polyamide; the diameter of the monofilament is 0.08-5mm; the strength of the monofilament is not less than 3.0CN / dtex; and the elongation at break is 15-35%. The production method is simple in process and is convenient to operate; and the formed fibers have the characteristics of high tenacity, high roundness, high uniformity and the like and have wide range of application.

Description
