Problems solved by technology

This kind of nylon mesh filament is spun from nylon resin with low relative viscosity, and the breaking strength is not high.
In addition, the black color necessary for filaments is dyed and finished after spinning. The blackness of the nets is not high, and the color uniformity is not enough. It will gradually fade during use, which will cause certain pollution to the ocean.

Embodiment

[0013] Add nylon resin, surface-active high-pigment carbon black, and modified EBS dispersant to a high-speed mixer at a ratio of 100:47:20 (weight ratio). The surface-active high-pigment carbon black is QCHT8 high-pigment carbon black pigment, and the modified EBS dispersant model is TAS-2A. After mixing, add parallel twin-screws for extrusion and granulation. The temperature settings of the twin-screws from front to back are: 80°C, 240°C, 240°C, 240°C, 240°C, 230°C, 230°C. Manufactured black nylon color masterbatch is at temperature 100 ℃, under the condition of residual pressure less than 1Kpa vacuum drying 4 hours stand-by.

Abstract

The invention relates to a melt blending spinning black high strength nylon filament and a production method thereof, and belongs to the field of textile manufacturing. The method is especially suitable for black high strength nylon filaments used in deep sea extraordinary catching nets. The nylon filament is produced through melt blending of 80-180 parts by weight of nylon resin, 0.5-3.0 parts by weight of surface-active high color black and 0.1-2.0 parts by weight of a modifying EBS dispersant and through spinning, wherein the nylon resin is nylon6 or nylon66, and the relative viscosity of the nylon resin is 2.7-3.6. A melt blending technology is adopted, the above black pigment is added into fibers, and the nylon resin with high relative viscosity is adopted, so the filament product obtained in the invention has the advantages of high breaking strength, high blackness, uniform color and fast color.

Description

technical field [0001] The invention relates to a black high-strength nylon filament produced by melt blending and a production method thereof. Especially suitable for black high-strength nylon filaments for deep-sea special fishing nets. It belongs to the field of textile manufacturing. technical background [0002] At present, in the deep-sea special fishing industry, special nets are generally made of soft black synthetic fibers. This nylon mesh filament is spun from nylon resin with low relative viscosity, and its breaking strength is not high. In addition, the black color necessary for the filament is dyed and finished after spinning. The blackness of the net is not high, and the color uniformity is not enough. It will gradually fade during use, which will cause certain pollution to the ocean. Therefore, the industry is eagerly looking forward to the advent of a technology that can make up for the above-mentioned deficiencies. Contents of the invention [0003] In...
