Embodiment 1
[0030] The production method of the functional nylon 6 fiber described in the present embodiment comprises the steps:
[0031] a. The step of drying the functional masterbatch using a masterbatch drying device, wherein the masterbatch drying device includes a masterbatch tank for holding the functional masterbatch. During the drying process, the masterbatch tank has a function from bottom to top Blowing, two streams of hot air blowing from the center to the outside to dry the functional masterbatch, the functional masterbatch is stirred and blown dry at the same time;
[0032] b. Uniformly mix the dried nylon 6 slices with the dried functional masterbatch obtained in step a, and then add the mixture to a screw extruder for melt extrusion; wherein, the nylon 6 slices and the functional masterbatch The matching ratio belongs to the prior art, and the general functional masterbatch is 3%-5% of the weight of nylon 6 slices;
[0033] c. Transport the fully melted mixed melt to the...
Embodiment 2
[0042] The production method of the functional nylon 6 fiber described in this embodiment differs from Example 1 in that: the functional masterbatch described in step a is a flame-retardant masterbatch, and the nylon 6 fiber prepared by this method is Fiber has flame retardant function.
[0043] In this example, the flame retardant masterbatch can be purchased from the market, or the flame retardant masterbatch specially developed by our company can be used, and the flame retardant masterbatch can be prepared according to the following steps:
[0044] 1. Use phosphorus-based or nitrogen-based aromatic polyamide organic amine compounds as flame retardants to make functional powders;
[0045] 2. Put the functional powder into an oven and dry and activate it at a temperature of 175°C;
[0046] 3. The functional powder obtained in step 2 is mixed with nylon 6 slices, dispersant (polymer wax), heat stabilizer C101, and antioxidant B215, wherein each component is calculated by weig...
Embodiment 3
[0051] The production method of the functional nylon 6 fiber described in this embodiment is different from Example 1 in that the nylon 6 fiber it makes has an anti-ultraviolet function, and the specific difference is that the functional masterbatch described in the step a It is an anti-ultraviolet masterbatch; the heating zone of the screw extruder in the step b is six, and its temperature is 262°C in the first zone, 268°C in the second zone, 268°C in the third zone, 268°C in the fourth zone, 268°C in the fifth zone, The sixth zone is 268°C, and the melt pressure is 12.0MPa; the fully melted mixed melt in the step c is transported to the spinning box through the heat preservation pipeline, and the temperature of the spinning box is 270°C; the side blowing temperature is 20°C, and the humidity 80%; the amount of oiling is 1.2%;: the drawing in the step d first adopts two cold rolls for drafting, and then uses two hot rolls for drafting. The temperature of the hot rolls is 175 °...
