Magnetic nylon-6 short fiber and manufacture method thereof
Technical field
The present invention relates to a kind of nylon fibre and preparation method thereof, particularly relate to a kind of magnetic nylon-6 short fiber and manufacture method thereof.
Background technology
Good characteristics such as conventional nylon fibre has high strength, high elasticity, dyeability is excellent and drapability is good.But along with improving constantly of people's living standard, people are also more and more higher to the health requirements of dress ornament.At present, polyamide fibre 6 functional fibres have a lot, as: polyamide fibre 6 far infrared fibers, polyamide fibre 6 anti-bacterial fibres, polyamide fibre 6 uvioresistant fibers etc., but also do not find magnetic nylon-6 short fiber so far.
Prove that through scientific experiment magnetic field acts on the biological effect (magnetic field effect) that causes behind the human body and is good for one's health, it can stimulate circulation, improve the microcirculation in human body state, promote cellular metabolism.And present magnetic fibre generally is carrier fibre with polypropylene fibre, and all is spun into long filament basically, its weak point: the one, and the dress ornament that is embodied in polypropylene fibre is poor than polyamide fibre; The 2nd, long filament can not be again with other such as fiber blends such as cotton textiles, wools, and can only when weaving cotton cloth, carry out shuffling, influenced dress ornament and Color.
Summary of the invention
The objective of the invention is to solve the deficiencies in the prior art part, provide a kind of and not only had the good dress ornament of polyamide fibre but also have the magnetic nylon-6 short fiber and the manufacture method thereof of magnetic health care function.
Technical scheme of the present invention is achieved in that
Magnetic nylon-6 short fiber of the present invention comprises magnetic function master batch and chinlon 6 section, and its percentage by weight is:
Magnetic function master batch: chinlon 6 section=1: 5~10;
Described magnetic function master batch comprises: function powder-granularity is the nano-scale magnetic powder Fe of 80~300nm
3O
4, carrier slice-chinlon 6 section, dispersant-macromolecule wax, coupling agent-SI900, antioxidant-PKB series B215, its percentage by weight is:
Function powder: carrier slice: dispersant: coupling agent: antioxidant=20: 79.5: 0.2: 0.1: 0.2.
The manufacture method of magnetic nylon-6 short fiber of the present invention comprises the following steps:
1, the preparation of magnetic function master batch:
(1) preparation function powder: with granularity is the nano-scale magnetic powder Fe of 80~300nm
3O
4As function powder;
(2) function powder is put into baking oven, under 110~180 ℃ temperature, carry out the drying activation;
(3) dried function powder is mixed with carrier slice-chinlon 6 section, dispersant-macromolecule wax, coupling agent-SI900, antioxidant-PKB series B215, its percentage by weight is:
Function powder: carrier slice: dispersant: coupling agent: antioxidant=20: 79.5: 0.2: 0.1: 0.2,
Said mixture fully stirs through homogenizer, carries out solid-state abundant mixing;
(4) said mixture is cooled to room temperature, joins in the extruder, under 230~300 ℃ temperature, the screw rod fusion pressure is under the condition of 2~6Mpa, with the extruder extruding pelletization, promptly obtains the magnetic function master batch.
2, the manufacturing of magnetic nylon-6 short fiber:
The magnetic function master batch is mixed according to following weight ratio with chinlon 6 section:
Magnetic function master batch: chinlon 6 section=1: 5~10;
Said mixture is joined in the extrusion spinning equipment, is under 230~300 ℃ at extruder temperature, and the screw rod fusion pressure is under the condition of 2~6Mpa, adopts the spinning speed of 400m/min to carry out spinning, wrapping wire, boundling, drawing-off, dehydration, curl, typing is cut off, and promptly obtains magnetic nylon-6 short fiber.
Usefulness of the present invention is: adopt the nano-scale magnetic powder to prepare the magnetic function master batch, again the magnetic function master batch is mixed with chinlon 6 section, spinning, break through the physical agglomeration and the dispersiveness of magnetic powder technically, improved the row yielding of spinning and the intensity of fiber; This fiber has increased magnetic function when having kept the nylon fibre good characteristic; Its single fiber fiber number is thin, and intensity is big, can with other fiber blend.
The specific embodiment
With granularity is the nano-scale magnetic powder Fe of 90nm
3O
4As function powder, get this function powder of 50Kg and put into baking oven, under 150 ℃ temperature, carry out the drying activation, take out after 4 hours; Dried function powder joined in the homogenizer stirs, and add successively:
Carrier slice-chinlon 6 section 19.875Kg
Antioxidant-PKB series B215 0.05Kg
Dispersant-macromolecule wax 0.05Kg
Coupling agent-SI900 0.025Kg
Through fully mixing, discharge the activation back, is cooled to room temperature, joins in the extruder, and under 260 ℃ temperature, the screw rod fusion pressure is an extruding pelletization under the condition of 4Mpa, promptly obtains magnetic function master batch 25Kg.
The magnetic function master batch is mixed according to following weight ratio with chinlon 6 section:
Magnetic function master batch: chinlon 6 section=1: 11;
Promptly in 25Kg magnetic function master batch, add the 275Kg chinlon 6 section.
This mixture is joined in the extrusion spinning equipment, is under 260 ℃ at extruder temperature, and the screw rod fusion pressure is under the condition of 4Mpa, adopts the spinning speed of 400m/min to carry out spinning, wrapping wire, boundling, drawing-off, dehydration, curl, typing is cut off, and promptly obtains magnetic nylon-6 short fiber 300Kg.
The quality index of this magnetic nylon-6 short fiber and row yielding are:
Fiber number dtex≤100 ± 10%
Relative intensity CN/dtex 3.14
Percentage elongation % 30.8
The rate of crispaturaing % 50.3
Curling stability % 30.1
Row yielding % 90.
This fiber can carry out blending such as fibers such as cotton textiles, wools with other, also can be used for making the acupuncture flocculus, and it not only has the good dress ornament characteristic of nylon fibre, has magnetic health care function simultaneously.
