Problems solved by technology

On the one hand, due to the large amount of inorganic ultraviolet shielding agent added, the cost of this process is relatively high. At the same time, due to the large amount of added amount, the spinning production is difficult, the waste rate in the production process is high, and the physical performance indicators of the product are also seriously affected.
On the other hand, the one-step spinning process is adopted, and the production speed is as high as 3000 m / min, which makes the process control of the production process difficult, and also results in high production consumption and low production efficiency, resulting in high production costs under this technology.

Abstract

The invention discloses ultraviolet-resisting nylon expanded filament yarns and a production process thereof. The preparation raw materials of the nylon expanded filament yarns comprise nylon color master batches; the nylon color master batches comprise the following components by mass percent: 20%-50% of cadmium pigments and 50%-80% of nylon; and the nylon color master batches further comprise 60ppm-150ppm cuprous ions. Compared with the prior art, the cuprous ions and the cadmium pigments cooperate so that the nylon ultraviolet-resisting function is enhanced; and meanwhile, the adding amount of a cuprous ion source, such as a cuprous compound, is effectively reduced by the cooperation effect, so that the cost is greatly reduced.

Description

technical field [0001] The invention relates to a nylon bulked filament, in particular to an ultraviolet-resistant nylon bulked filament, and also relates to a production process of the nylon bulked filament. Background technique [0002] Nylon 66 (PA66) fiber has become the preferred raw material for high-end commercial carpets due to its excellent elastic recovery, wear resistance and good flame retardancy. Light irradiation will not only make the color lighter, but also reduce the strength and wear resistance of the carpet surface, so that the life of the whole batch of carpets will be shortened, which will increase the operating cost for users. Thereby, it is an important development subject to develop a kind of anti-sunlight and UV-resistant carpet. [0003] At present, the anti-ultraviolet products and technologies developed in the carpet manufacturing industry and the carpet fiber production industry are: (1) in the carpet manufacturing industry, an anti-ultraviolet ...
