Problems solved by technology

The current magnetic fibers generally use polypropylene as the carrier fiber, and are basically spun into filaments. The disadvantages are: first, the clothing performance of polypropylene is worse than that of nylon; Wool and other fibers are blended, but they can only be blended when weaving, which affects the clothing and dyeing effect

Embodiment Construction

[0023] The nano-scale magnetic powder Fe with a particle size of 90nm 3 o 4 As a functional powder, put 50Kg of the functional powder into an oven, dry and activate it at a temperature of 150°C, and take it out after 4 hours; add the dried functional powder into a high-speed mixer for stirring, and add in succession:

[0024] Carrier slices—nylon 6 slices 19.875Kg

[0025] Antioxidant—PKB series B2 150.05Kg

[0026] Dispersant - polymer wax 0.05Kg

[0027] Coupling agent—SI900 0.025Kg

[0028] Fully stirred and mixed, discharged after activation, cooled to room temperature, added to the extruder, extruded and granulated at a temperature of 260°C and a screw melting pressure of 4Mpa to obtain 25Kg of magnetic functional masterbatch.

[0029] Mix the magnetic functional masterbatch with nylon 6 chips according to the following weight ratio:

[0030] Magnetic functional masterbatch: Nylon 6 slices = 1:11;

[0031] That is, add 275Kg nylon 6 slices to 25Kg magnetic functiona...

Abstract

The magnetic nylon-6 short fiber is made with magnetic functional agglomerate and nylon chip in the weight ratio of 1 to 5-10. The magnetic functional agglomerate includes functional powder, carrier chip, dispersant, coupler and antioxidant in certain weight proportion. The making process of the magnetic nylon-6 short fiber includes the following steps: 1. preparing the magnetic functional agglomerate through preparing functional powder of Fe3O4, drying and activating the functional powder, mixing the functional powder with carrier chip, dispersant, coupler and antioxidant in certain weight proportion via high speed stirring, cooling the mixture to room temperature, and extruding and pelletizing in extruder; and 2. producing magnetic nylon-6 short fiber through mixing magnetic functional agglomerate and nylon chip, spinning the mixture, winding, bundling, drafting, dewatering, crimping, setting and cutting.

Description

technical field [0001] The invention relates to a nylon fiber and a manufacturing method thereof, in particular to a nylon 6 magnetic short fiber and a manufacturing method thereof. Background technique [0002] Conventional nylon fiber has excellent characteristics such as high strength, high elasticity, excellent dyeability and good drapability. But, along with the continuous improvement of people's living standards, people's health requirements for clothing are getting higher and higher. At present, there are many nylon 6 functional fibers, such as: nylon 6 far-infrared fiber, nylon 6 antibacterial fiber, nylon 6 anti-ultraviolet fiber, etc., but no nylon 6 magnetic short fiber has been found so far. [0003] Scientific experiments have proved that the biological effect (magnetic field effect) caused by the magnetic field acting on the human body is beneficial to health. It can promote blood circulation, improve the microcirculation state of the hum...
