Embodiment 1

[0030] The dry composite anti-radiation masterbatch, black masterbatch and nylon 6 slices are evenly mixed, and added to a screw extruder for melt extrusion. The component composition of the above mixture is shown in Table 1 below. Among them, the composition of the composite anti-radiation masterbatch is shown in Table 2 below. Black masterbatch includes 40% pigment black components, 0.4% dispersant and 59.6% nylon 6 chips. The heating zone temperature and melt pressure of the screw extruder are shown in Table 3.

[0031] The fully melted melt is transported to the spinning box through a special melt pipeline. The temperature of the spinning box is 260°C, and the melt is extruded to the spinning assembly in a constant amount by the spinning metering pump for spinning. After the bundle is sprayed from the spinneret hole, it is cooled and formed by side blowing, the temperature of the side blowing is 17°C, and the humidity is 80%; then the cooled tow is oiled. In order to in...

Embodiment 2

[0034] Mix the dried composite anti-radiation masterbatch, gray masterbatch and nylon 6 slices evenly, and put them into a screw extruder for melt extrusion. The component composition of the above mixture is shown in Table 1 below. Among them, the composition of the composite anti-radiation masterbatch is shown in Table 2 below. Gray masterbatch includes 45% pigment ash component, 0.5% dispersant and 54.5% nylon 6 chips. The heating zone temperature and melt pressure of the screw extruder are shown in Table 3.

[0035] The fully melted melt is transported to the spinning box through a special melt pipeline. The temperature of the spinning box is 263 ° C. The melt is extruded to the spinning assembly in a constant amount by the spinning metering pump for spinning. After the tow is sprayed from the spinneret hole, it is cooled and formed by side blowing, the temperature of the side blowing is 18°C, and the humidity is 75%; then the cooled tow is oiled. In order to increase th...

Embodiment 3

[0038] The dry composite anti-radiation masterbatch, brown masterbatch and nylon 6 slices are evenly mixed, and added to a screw extruder for melt extrusion. The component composition of the above mixture is shown in Table 1 below. Among them, the composition of the composite anti-radiation masterbatch is shown in Table 2 below. Brown masterbatch includes 50% brown pigment components, 0.6% dispersant and 49.4% nylon 6 chips. The heating zone temperature and melt pressure of the screw extruder are shown in Table 3.

[0039] The fully melted melt is transported to the spinning box through a special melt pipeline, and the temperature of the spinning box is 265°C. The melt is extruded to the spinning assembly in a constant amount by the spinning metering pump for spinning. After the bundle is sprayed from the spinneret hole, it is cooled and formed by side blowing, the temperature of the side blowing is 18°C, and the humidity is 70%; then the cooled tow is oiled. In order to in...

Abstract

The invention discloses a multifunctional polyamide 6 fiber, which includes, by weight, 3.0-5.0% of a composite anti-radiation masterbatch, 3.0-5.0% of a colored masterbatch and 90.0-94.0% a polyamide 6 chip. The invention also discloses a making method for the multifunctional polyamide 6 fiber. The method comprises the steps of: a. mixing the dried composite anti-radiation masterbatch, colored masterbatch and polyamide 6 chip evenly, adding the mixture into a screw extruder to undergo melting; b. subjecting the mixed melt to extrusion spinning through a metering pump, and subjecting the tow to side blowing air cooling forming and oiling; and c. subjecting the tow to pre-interlacing and drafting by cold and hot rollers, conducting interlacing, then conducting high-speed winding forming, carrying out physical performance examination and dyeing test, and if qualified, finally performing grading packaging to obtain the multifunctional polyamide 6 fiber finished product. With colored, antibacterial, anti-radiation and other multiple functions, the multifunctional polyamide 6 fiber provided by the invention has lasting and stable washable and anti-radiation effects.

Description

technical field [0001] The invention relates to a multifunctional nylon 6 fiber and a manufacturing method thereof, in particular to an antibacterial and radiation-resistant nylon 6 fiber and a manufacturing method thereof. Background technique [0002] The main species of nylon is aliphatic polyamide fiber, which can be synthesized from a monomer, such as lactam or amino acid. At this time, the Arabic numerals after the name of nylon indicate the number of carbon atoms of the lactam or amino acid used, such as nylon 6, nylon 66, etc. Nylon 6 is polycaprolactam fiber. The 412th page of the "Chemical Fiber Dictionary" printed in the second edition of the first edition in 1995 disclosed this concept: polycaprolactam fiber is referred to as polycaprolactam fiber in my country. Filament, textured filament and short fiber, etc., are produced by melt direct spinning or chip spinning. Nylon 6 products have the characteristics of high strength, wear resistance, softness and mild sk...
