Embodiment 1
[0024] Please refer to figure 1 As shown, the aramid fiber and nickel-iron fiber blended yarn of the present invention comprises: 75-95 parts by weight of aramid and 5-25 parts by weight of nickel-iron fiber. Preferably, the aramid fiber and nickel-iron fiber blended yarn of the present invention comprises 90 parts by weight of aramid fiber and 10 parts by weight of nickel-iron fiber.
[0025] Preferably, the aramid fiber and ferronickel fiber blended yarn of the present invention comprises: 85 parts by weight of aramid fiber and 15 parts by weight of ferronickel fiber.
[0026] Preferably, the aramid fiber and ferronickel fiber blended yarn of the present invention comprises: 80 parts by weight of aramid fiber and 20 parts by weight of ferronickel fiber.
[0027] The preparation process of the aramid fiber and the nickel-iron fiber blended yarn of the present invention is mixed by a drawing process, wherein, the aramid fiber of the present invention adopts aramid fiber 1414,...
Embodiment 2
[0030] The specific steps of the preparation process of the aramid fiber and nickel-iron fiber blended yarn of the present invention are as follows:
[0031] Step A: cleaning and carding process, the aramid fiber of the present invention adopts aramid fiber 1414;
[0032] Step A1: Loosen the compressed aramid fiber 1414 into smaller fiber blocks or fiber bundles, so as to facilitate the smooth progress of mixing and impurity removal;
[0033] Step A2: Remove most of the impurities, defects and short fibers that are not suitable for spinning in the original pressed aramid 1414 fibers;
[0034] Step A3: Mixing the original aramid 1414 staple fibers of different compositions sufficiently and uniformly to stabilize the quality of the aramid 1414 fibers;
[0035] Step A4: A aramid 1414 fiber roll with a certain weight, length, uniform thickness and good shape is made.
[0036] Through the cleaning and carding process of this step, the aramid 1414 fibers are decomposed into a sing...

[0060] Performance testing of 3 blended yarns
[0061] The three kinds of aramid and nickel-iron blended yarns with different nickel-iron fiber contents of the present invention were respectively carried out in multiple groups of experiments to measure the yarn strength, yarn hairiness and abrasion resistance and conduct performance analysis. The specific results are shown in Table 6.
[0062] Table 6 Performance test results of nickel-iron fiber blended yarn
[0063]
[0064] Table 7 Comparison of nickel-iron fiber blended yarn of the present invention with other blended yarns
[0065]
[0066] The aramid fiber and nickel-iron fiber blended yarn of the present invention has good mechanical properties, high breaking strength and low elongation at break, and the aramid and nickel-iron fiber blended yarn of the present invention can be used for producing high strength and high strength Molded flame retardant textiles, and then through blending or finishing, endow them wi...
