Embodiment 1

[0078] The argon gas was continuously filled into the operation box, and the air in it was exhausted. The air pressure in the operation box was kept at 1.0 kPa lower than the ambient pressure, and the oxygen content was 0.05%. Inject 90 parts of NdFeB magnetic powder into 20 parts of vegetable oil, then add 1.5 parts of silicone additives and transfer to a vertical ball mill to obtain a coated magnetic powder composition. The magnetic powder composition was subjected to vacuum pump filtration, and the excess 11.5 parts of coating agent were filtered off to obtain the final NdFeB magnetic powder composition. Under the protection of nitrogen, 40 parts of rare earth magnetic powder composition was added to 60 parts of polyethylene terephthalate chip powder, mixed and evenly mixed, extruded and granulated by twin-screw extruder at 280 ° C to obtain Core material magnetic masterbatch.

[0079] Mix 55 parts of polyamide 6, 40 parts of titanium dioxide, 2 parts of silane coupling ag...

Embodiment 2

[0083] A rare earth magnetic powder composition was prepared in the same manner as in Example 1. Then, under the protection of nitrogen, 40 parts of the rare earth magnetic powder composition was added to 60 parts of polyamide 6 slices, mixed and evenly mixed, extruded and granulated by a twin-screw extruder at 250° C. to obtain magnetic masterbatches for the core layer.

[0084] Mix 60 parts of polybutylene terephthalate, 35 parts of phthalocyanine blue, 2 parts of silane coupling agent, and 3 parts of ethylene acrylic acid copolymer. out, granulate, and make masterbatch.

[0085] Take 70 parts of dried polyamide 6 and 30 parts of magnetic masterbatch, and mix them thoroughly to prepare the fiber core layer material. Take 98.5 parts of dried polybutylene terephthalate and 1.5 parts of color masterbatch, and mix them thoroughly to obtain the skin material.

[0086] The skin layer material and the core layer material are spun with a skin-core composite spinning machine at a w...

Embodiment 3

[0088] A rare earth magnetic powder composition was prepared in the same manner as in Example 1. Then, under the protection of nitrogen, add 40 parts of rare earth magnetic powder composition to 60 parts of poly(trimethylene terephthalate), mix and mix, extrude and granulate through a twin-screw extruder at 250°C to obtain a magnetic core material. Masterbatch.

[0089] 58 parts of polyamide 66, 40 parts of carbon black, 1 part of titanate coupling agent, and 1 part of polyolefin are thoroughly mixed, extruded through a twin-screw extruder at 280 ° C, and granulated to obtain a color Masterbatch.

[0090] Take 75 parts of dry polytrimethylene terephthalate and 25 parts of magnetic masterbatch and mix thoroughly to prepare the fiber core layer material. Take 97 parts of dried polyamide 66 and 3 parts of color masterbatch, and mix them thoroughly to obtain the skin material.

[0091] The skin layer material and the core layer material are spun with a skin-core composite spinn...

Abstract

The invention relates to a milk white or colorful magnetic fiber filament meeting the textile color requirement and a preparing method thereof. The milk white or colorful magnetic fiber filament is characterized in that the magnetic fiber filament is of a skin-core structure, and a skin layer material and a core layer material of the magnetic fiber filament adopt polyamide / polyester chips which are different in polarity respectively, wherein the skin layer material of the magnetic fiber filament comprises color master batches, and the core layer material of the magnetic fiber filament comprises magnetic master batches. According to the milk white or colorful magnetic fiber filament meeting the textile color requirement and the preparing method thereof, a milk white or colorful magnetic fiber effectively isolates air and water of the magnetic master batches in the core layer material through the polyamide / polyester chips with the different polarities in the core layer material and the skin layer material, the long-term effect of filter magnetism is guaranteed, and the single color problem in the existing magnetic fiber preparing technology is solved by adding the color master batches into the skin layer material.

Description

technical field [0001] The invention relates to the field of textile fabrics, in particular to a milky white or colored magnetic fiber filament suitable for the color requirements of textiles and a preparation method thereof. Background technique [0002] With the development of magnetic therapy technology and health care, textiles with magnetic therapy function have been developed and put into use. The mechanism of magnetic therapy is generally believed to be: the magnetic field promotes circulation by reducing the viscosity of body fluids, activates biological enzymes, controls the movement of hemoglobin, etc., and is effective in reducing stasis, reducing swelling and inflammation, reducing trauma scars, relieving pain, improving sleep, and relieving depression. Reliable curative effect, and safe, non-invasive, non-toxic, for the static magnetic field, even if the magnetic induction intensity reaches 2000G, it is still safe for the human body. In short, magnetic therapy ...
