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
The present invention relates to a kind of special magnetic polyster fibre and production method thereof, belong to the fiber production technology field.
Background technology
Magnetic fibre is a kind of functional fibre that human body is had certain health-care function.Many patent documentations report is also arranged both at home and abroad, for example, day the disclosure a kind of method that adopts core-skin manufactured magnetic fibre.Its cortex is a polymer, and sandwich layer is the mixture of polymer and magnetic.Chinese patent CN1252460 number a kind of magnetic health care fiber manufacturing technology is disclosed.It is that magnetic particle fully is mixed and made into master batch with far infrared particulate and vector resin in proportion, again the magnetic health care fiber that makes with material resin blend spinning in proportion.This fiber hard magnetic material accounts for 10%～50% of master batch weight, and this master batch addition is 15%～30% in the spinning.Though this technology can have magnetic and far-infrared functional simultaneously, also exists following deficiency: on the one hand because particle content lower (account for total weight of fiber 1.5%～15%), the magnetic property of fiber is not obvious; On the other hand, because the far infrared particulate is by absorbing and the emitting far-infrared health-care function that reaches human body, magnetic particles then is by the magnetic field of certain intensity human body to be played health-care function, both health-care function mechanism differences, magnetic is mixed use and makes the magnetic far-infrared health fiber with far infrared, can make their function phase mutual interference, cause function reduction, influence the performance of its health care (particularly influencing its magnetic property) effect, actual health-care function is not obvious.
Summary of the invention
At the deficiencies in the prior art, the invention provides a kind of functional fiber and high efficiency production method thereof with long-acting magnetic.
The technical solution used in the present invention is:
1, adopt chemical reaction method or physical mechanical comminuting method to prepare nano-magnetic powder required for the present invention.The described magnetic of magnetic fibre of the present invention is a tri-iron tetroxide, one or more in strontium ferrite, barium ferrite, money iron boron, the ferronickel boron.When multiple magnetic was used with, ratio was not particularly limited.
2, utilize melt spinning production magnetic terylene, production procedure is spun identical with common section.The percentage by weight prescription that it is characterized in that this magnetic fibre comprises:
The PET content 40～82% of cutting into slices; Magnetic 16～65%; Silicon surface active agent 1～4%; Modifier 2～1%, described magnetic average grain diameter≤30nm; Described silicon surface active agent average grain diameter is≤65nm.
The concrete production process of magnetic fibre of the present invention is as follows:
1. make the fibre spinning material: after mixing in PET section, magnetic, silicon surface active agent and the modifier of described ratio are even, under 180～280 ℃ of temperature, extrude through twin-screw, granulation obtains described fibre spinning material;
2. make fiber: the fibre spinning material that will 1. go on foot gained, spin out finished silk with melt spinning machine, its production procedure is: drying → screw rod melt extrudes → cools off valve, measuring pump, spinning pack → lateral blowing device → oil → → two road stretching → network equipments → fracture of wire automatic stop arrangement → coiling that stretches together → balance external inspection → packing warehouse-in.
3. the fiber processing of magnetizing: will 2. go on foot the gained finished silk and magnetize under magnetic field intensity 12000～20000 Gausses, the time of magnetizing is 1～3 minute, can obtain described magnetic fibre.
Magnetic powder content in the fiber of the present invention reaches as high as 65% of total weight of fiber and helps improving magnetic field intensity, and then improves the medical care effect of fiber.After measured, the magnetic field intensity average of magnetic fibre of the present invention is 2～85 Gausses, and owing to adopted unique magnetic production technology, can guarantee that used magnetic has long-acting magnetic and the speed that magnetizes fast.
The specific embodiment
Get 35 parts of (weight of dried PET section, down with), 2 parts of silver chlorate powders, 1 part of sodium pentachlorophenol, 1 part in silicon face activator (SiO 2 powder), silver-colored ferromagnetic oxide powder account for 1 part of 610 part, three different stearic phthalidyl ferrous acid isopropyl esters, after fully mixing, under 267 ℃, extrude through twin-screw, granulation produces the spinning compound; After the gained compound fully dried, spin out the FDY silk, be finished product with melt spinning stretching all-in-one; To the finished silk processing of magnetizing, magnetize under magnetic field intensity 12000 Gausses at last, the time of magnetizing is 2 minutes, can obtain described magnetic fibre.
After measured, the magnetic field intensity average of gained fiber is 43 Gausses, and also has the sterilizing rate up to 65%.The described magnetic fibre of present embodiment can be used for producing home textile products such as fitted sheet, sheet, quilt cover, pillowcase.
