Problems solved by technology
For example, in the same production process steps, if the process parameters are different, although nylon fibers can also be produced, their properties are different. However, not all of these nylon fibers with different properties meet the market demand, and most of them have no market. Competitiveness, or the performance index does not meet the requirements; another example, the production process steps are different, although the cross-sectional shape of the produced nylon fiber is different, but its performance is also very different, and for example, the different cross-section of nylon fiber means that the structure are all different, which means that the production process steps and various process parameters also need to be redesigned

Embodiment Construction
[0033] see Figures 1 to 4 As shown, the reference number of the present invention does not use "6" to avoid confusion with the number in the nylon 6, while the reference number "80" is nylon 6 to avoid confusion, and there is no label behind the nylon 6 80.
[0034] The invention provides a new type of nylon 6 with FDY matte flat section. The cross section of the nylon 6 is "one" shape, and the two ends of the cross section are arc transitions, so as to form a new filament.
[0035] The nylon 6 has a linear density of 40.6 dtex / F, a breaking strength of 4.59 CN / dtex, a breaking elongation of 48%, a boiling water shrinkage of 9.8%, an oil content of 1.6%, and an unevenness of evenness of 1.33%. , the network is 6 pieces / meter, and the dyeing is controlled at 5.0 grades. When these performance parameters of the nylon 6 of the present invention are satisfied at the same time, the performance is better, and the market value is high, so that the nylon 6 of the present invention h...

Abstract
The invention provides novel FDY polyamide fiber 6 with a delustered flat section and a production process. New design is adopted for structure of polyamide fiber 6, cross section is I-shaped, and twoends of the cross section are in arc transition to form a new strand, so that the polyamide fiber 6 is smooth, elastic and soft in hand feel and high in three-dimensionality; clothes manufactured byusing the polyamide fiber 6 are comfortable in wear and have the advantages of being hygroscopic and quick in heat dissipation; the polyamide fiber 6 is new fiber easier in coloring, and product typesare enriched, so that more options are provided for downstream production clients, and market competitiveness is improved. The production process is simple in flow, high in efficiency, high and stable in product quality, capable of effectively meeting market needs and wide in application prospect.
Description
【Technical field】 [0001] The invention relates to the manufacturing technology of spinning, in particular to a new type of nylon 6 with FDY matte flat section and its production process. 【Background technique】 [0002] For nylon fiber, its performance is affected by cross-sectional shape, production process steps and various process parameters in the production process. These conditions are different, and the performance obtained is also different. For example, with the same production process steps, if the process parameters are different, although nylon fibers can also be produced, their properties are different. However, not all of these nylon fibers with different properties meet market demand, and most of them have no market. Competitiveness, or performance indicators do not meet the requirements; another example, the production process steps are different, although the cross-sectional shape of the produced nylon fiber is different, but its performance is also very diff...
