Problems solved by technology

Although this technology can have both magnetic and far-infrared functions, it also has the following shortcomings: on the one hand, the magnetic properties of the fibers are not obvious due to the low content of magnetic powder (accounting for 1.5% to 15% of the total weight of the fibers); on the other hand, Because the far-infrared particles achieve the health care effect on the human body by absorbing and emitting far-infrared rays, the magnetic powder particles play a health care effect on the human body through a magnetic field of a certain strength. And made into magnetic far-infrared health-care fibers, their functional effects will interfere with each other, resulting in functional decline, affecting the performance of its health-care functions (especially affecting its magnetic properties), and the actual health-care effects are not obvious

Embodiment Construction

[0013] Take 35 parts of dried PET chips (weight, the same below), 2 parts of silver chloride powder, 1 part of sodium pentachlorophenolate, 1 part of silicon surfactant (silicon dioxide powder), and 610 parts of silver ferrite magnetic powder 1 part of isopropyl triisostearyl phthaloferrate, after being fully mixed, extruded by twin-screw at 267°C, granulated to produce a mixture for spinning; after fully drying the obtained mixture, The FDY yarn is spun by a melt-spinning and stretching integrated machine, which is the finished product; finally, the finished yarn is magnetized at a magnetic field strength of 12000 gauss, and the magnetization time is 2 minutes, and the magnetic fiber can be obtained .

[0014] It is determined that the average magnetic field intensity of the obtained fiber is 43 gauss, and the sterilization rate is as high as 65%. The magnetic fibers described in this embodiment can be used to produce home textile products such as bed sheets, bed sheets, qui...

Abstract

The invention relates to magnetic terylene fiber and the production method thereof. The fiber is characterized in that mixture comprises 40 to 82 percent of PET chips, 16 to 65 percent of magnetic powder, 1 to 4 percent of silicon surface activating agent, and 2 to 1 percent of modifying agent, the average particle diameter of the magnetic powder is lower than or equal to 30 nanometers; the average particle diameter of the silicon surface activating agent is lower than or equal to 65 nanometers. The production process of the fiber comprises fiber spinning material manufacturing, fiber manufacturing, and fiber magnetizing treatment. The fiber of the invention has better magnetic health care capability, and according to the difference of the modifying agent, the fiber also has antibiosis and other functions.

Description

technical field [0001] The invention relates to a special magnetic polyester fiber and a production method thereof, belonging to the technical field of fiber production. Background technique [0002] Magnetic fiber is a functional fiber that has a certain health care effect on the human body. There are also many patent literature reports at home and abroad, for example, a method for manufacturing magnetic fibers by the skin-core method is disclosed in Japan. Its skin layer is polymer, and the core layer is a mixture of polymer and magnetic powder. Chinese patent CN1252460 discloses a kind of magnetic health care fiber manufacturing technology. It is a magnetic health-care fiber made by fully mixing magnetic particles with far-infrared particles and carrier resin in proportion to make masterbatch, and then mixing with raw resin in proportion and spinning. The fibrous hard magnetic material accounts for 10%-50% of the weight of the master batch, and the added amount of the ...
