Description
Technical field
The invention belongs to chemical fiber field, more particularly, to a kind of durability antibacterial polyacrylonitrile fiber.
Background technology
Polyacrylonitrile outward appearance is fluffy, soft, with good fast light, weatherability, its elasticity and warmth retention property, has
The title of " artificial wool ".Main status is accounted in the raw materials used middle polyacrylonitrile of China's wool spinning and artificial fur.Polyacrylonitrile
Premium properties makes it be widely used in clothes, dress ornament, the big field of industry three.Polyacrylonitrile fibre is according to different purposes
It is required that can pure spinning or with it is natural fibre blended, or be made into woollen blanket, carpet etc., can also be mixed with cotton, staple fibre, other synthetic fibers
Spin, be made into various dress materials and indoor article.
As people are to indoor, bedding and the raising of clothing functionization requirement, the polyacrylonitrile with antibiotic property
The exploitation of fiber also turns into focus.The preparation method of antibacterial polyacrylonitrile fiber mainly has two kinds.One kind is fine in polyacrylonitrile
Dimension carries out antimicrobial treatment after being formed to it, mainly antiseptic is adhered to fiber surface by means of the effect of adhesive, made
Though standby polyacrylonitrile fibre has preferable anti-microbial property, come off due to the easy aging of adhesive or by rubbing action so that
Antibacterial effect is had a greatly reduced quality in use, and usage cycles are significantly shorter；Another is that anti-bacterial powder and spinning solution are blended
Spinning and obtain the polyacrylonitrile fibre with antibiotic property, but because the antibiotic property of fiber is mainly reflected in antibacterial material and bacterium
Directly contact and play a role, but anti-bacterial powder is mainly distributed on fiber in the antibacterial polyacrylonitrile fiber prepared by this method
Inside, fiber surface distribution is less, and anti-bacterial powder is difficult in solid fabric internal migration, the availability of anti-bacterial powder compared with
It is low.
From the foregoing, it will be observed that the effective rate of utilization of anti-bacterial powder is improved, antibacterial polyacrylonitrile of the exploitation with durability antibiotic property
Fiber has wide market prospects.
The content of the invention
To overcome current anti-bacterial powder effective rate of utilization relatively low, durability antibiotic property polyacrylonitrile fibre underexploitation is asked
Topic, the present invention provides a kind of durability antibacterial polyacrylonitrile fiber.
The present invention is realized by following technology：
A kind of durability antibacterial polyacrylonitrile fiber, the durability antibacterial polyacrylonitrile fiber is made up of sandwich layer with cortex, institute
Sandwich layer is stated for polyacrylonitrile, the cortex is antibiotic layer, the durability antibacterial polyacrylonitrile fiber preparation process is as follows：
1) preparation of polyacrylonitrile spinning solution：Will be single by taking off by the polyacrylonitrile polymer fluid obtained by solution polymerization process
Body, mixing, deaeration, filtering, obtain polyacrylonitrile spinning solution (1)；
2) anti-bacterial powder prepares：Antiseptic is milled to 10000~15000 mesh using mechanical ball mill instrument, anti-bacterial powder is produced；
3) spinning：Polyacrylonitrile spinning solution (1) is extruded by spinneret (2), into spinning shaft (5), carries anti-bacterial powder
Hot-air spinning shaft (5) is blown into by air intake vent (4), porous plate (3), by air outlet (6) blow out, in hot-air flow process
In, anti-bacterial powder adheres to polyacrylonitrile spinning solution (1) surface；Then, the polyacrylonitrile that surface adhesion has anti-bacterial powder is spun
Silk stock solution (1) is introduced into curing molding in coagulating bath (7), produces antibacterial polyacrylonitrile precursor；
4) cleaning is with collecting：Antibacterial polyacrylonitrile precursor introduces clear water bath (9) washing, drying roller (10) through godet (8) and done
Dry, collection obtains durability antibacterial polyacrylonitrile fiber (11).
Traditional polyacrylonitrile spinning technique is directly entered solidifying for wet spinning, i.e. polyacrylonitrile spinning solution by spinneret
Gu carry out being solidified into silk in bath.Traditional polyacrylonitrile wet spinning process is different from, the present invention is in spinneret and coagulating bath
Between especially add spinning shaft, its length is 25~35 centimetres, air intake vent and air outlet is configured on slinning cabinet, in the spinning
The antibacterial functions that path region can complete polyacrylonitrile are modified.
The method that traditional anti-bacterial powder is directly added into spinning solution is different from, the present invention utilizes the rolling action of hot-air,
Anti-bacterial powder is adhered to the surface of polyacryl-nitrile spinning fluid, under the blending with top layer polyacryl-nitrile spinning fluid, makes antibacterial powder
End is evenly distributed on the top layer of polyacryl-nitrile spinning fluid, and antibacterial polyacrylonitrile fiber obtained by the solidification through coagulating bath is core-skin knot
Structure, sandwich layer is consistent with plain polypropylene nitrile fiber basis, and cortex is then antibiotic layer.It is total to traditional anti-bacterial powder and spinning solution
Blended ratio is made polyacrylonitrile fibre material and compared, and less anti-bacterial powder amount can be used in the present invention, and plays preferable antibacterial
Effect.
The mechanical performance of polyacrylonitrile fibre obtained by the present invention is similar to plain polypropylene nitrile fiber, and anti-bacterial powder exists
Polyacrylonitrile fibre surface distributed is more uniform, and its thickness depends primarily on the concentration and air velocity of anti-bacterial powder in hot-air,
Higher anti-bacterial powder concentration, throughput then contribute to obtain the polyacrylonitrile fibre of more preferable antibacterial effect.
Preferably, the length of the spinning shaft (5) is 25~35 centimetres.
Preferably, the temperature of the hot-air is 60~70 DEG C, and throughput is 0.5~1.5m3/min。
Preferably, the concentration of anti-bacterial powder is 200~1000mg/L in hot-air.
Preferably, the antiseptic is silver ion antimicrobial agent, copper ion antiseptic, nickel ion antiseptic, zinc ion antibacterial
One or more in agent and lead ion antiseptic.
Preferably, the coagulating bath (7) is 100~110g/L sulphur hydracid sodium water solutions, and temperature is 6~15 DEG C.
Preferably, the polyacrylonitrile spinning solution (1) includes following composition：The parts by weight of polyacrylonitrile 13~15, sulphur hydrogen
The sour parts by weight of sodium 40~45, the parts by weight of deionized water 40~47.
Preferably, the number-average molecular weight of the polyacrylonitrile is 80000~120000.
Preferably, the temperature of the polyacrylonitrile spinning solution (1) is 36~38 DEG C.
Traditionally in polyacrylonitrile spinning solution the number-average molecular weight general control of polyacrylonitrile 50000~100000,
In the present invention, the number-average molecular weight for the polyacrylonitrile that inventor is used is 80000~120000.The raising of number-average molecular weight
Beneficial to the viscosity for improving spinning solution, the raising of spinning fluid viscosity be conducive to anti-bacterial powder prepare adhesion on spinning solution surface with
The fixation on top layer.
The beneficial effects of the present invention are：Using the rolling action of hot-air, anti-bacterial powder is adhered into polyacrylonitrile and spun
The surface of silk liquid, under the blending with top layer polyacryl-nitrile spinning fluid, makes anti-bacterial powder be evenly distributed on polyacryl-nitrile spinning fluid
Top layer, obtained durability antibacterial polyacrylonitrile fiber has preferable antibacterial fastness, antibacterial effect, and usage cycles are longer
