Lower dyeing temperature caused by lower heat-resistant temperature, so the brightness, color difference and color fastness of dyed fiber are far from meeting the requirements of the market
The main risks of nanoscale organic heterocyclic pigments are agglomeration and migration, which may adversely affect color uniformity and color fastness

preparation example B1

[0057] Use jet milling method to crush 1 kg of disperse disperse dye fa material powder to a particle size of no more than 150 nanometers, and then use emulsion polymerization to coat it with polymers. The specific steps are: dissolve 50 g of emulsifier ra in 50 L of deionized Then add 1 kg of disperse dye powder into the water, and stir slowly until the disperse dye is wetted; after stirring for 1 h (1500 r / min) under the IKA high-speed mixer, the dispersion is transferred to an ultrasonic pulverizer for ultrasonic dispersion for 2 h, and dispersed in the ultrasonic process The liquid is cooled by a water bath to prevent the temperature rise from affecting the dispersion effect. Thereafter, 0.3 kg of styrene monomer and 0.5 g of azobisisobutyronitrile initiator were added, and stirred at a high speed of 2000 r / min for 3 h for emulsification. Finally, the emulsification system was transferred from the stainless steel drum to a 150L polymerization kettle, and the temperature wa...

Abstract

The invention provides a colored ultra-high molecular weight polyethylene fiber and a preparation method thereof. The colored ultra-high molecular weight polyethylene fiber is characterized by comprising an ultra-high molecular weight polyethylene with the viscosity average molecular weight of 1 million-10 million and a coloring system, wherein the content of the coloring system accounts for 0.1-10% by weight of the ultra-high molecular weight polyethylene, the coloring system is at least one of a coating dye and a coating pigment, the coating dye contains a coating and a dispersive dye, the weight ratio of the coating to the dispersive dye is 10:90 to 80:20; the coating pigment contains a coating and a pigment, and the weight ratio of the coating to the pigment is 10:90 to 80:20. The preparation method is that the coating dye and the pigment are added to a spinning stock solution to prepared the colored ultra-high molecular weight polyethylene fiber through stock solution coloring. The colored fiber prepared by adopting the method is uniform in coloring, and excellent mechanical strength and color fastness are endowed to the fiber while the excellent mechanical strength of the fiber is kept.

Description

technical field [0001] The invention belongs to the field of high-performance fibers and relates to a colored ultra-high molecular weight polyethylene fiber. Specifically, the invention relates to a high-performance colored fiber containing ultra-high molecular weight polyethylene and a preparation method thereof. Background technique [0002] Ultra-high molecular weight polyethylene (UHMWPE) fiber is a linear structure polyethylene fiber with a molecular weight greater than 1 million. It is the third generation of high-strength, high-modulus, high-performance special fibers after carbon fibers and aramid fibers in the world. Although the main chain structure of UHMWPE fiber is the same as that of ordinary polyethylene fiber, the extremely high molecular weight endows UHMWPE fiber with good stability, abrasion resistance, cutting resistance, chemical corrosion resistance, high crystallinity, high water resistance, impact resistance and surface Smooth, light, soft and other ...
