Description
Technical field
The application belongs to field of new materials, and in particular to a kind of high-strength composite nonwoven with bacteriostasis.
Background technique
Non-woven fabrics is made of fiber orient or random.It is called because of the appearance and certain performances with cloth
Cloth.Non-woven fabrics have it is moisture-proof, ventilative, flexible, light, not combustion-supporting, be easy decompose, it is nontoxic it is nonirritant, rich in color, price is low
The features such as honest and clean, recyclable.Such as mostly use polypropylene（Pp material）Pellet is raw material, through high-temperature fusion, spinneret, paving guiding principle, heat
Writing that surpasses all the others takes continuous one-step to produce.
Now, the application range of non-woven fabrics is wider, in some special dimensions, non-woven fabrics is needed to have good antibacterial work
With realizing often through addition silver ion or the modes of other bacteriostatic agents, still, inevitably will cause in use
Bacteriostatic agent is precipitated, and causes security risk.
Summary of the invention
The object of the present invention is to provide a kind of high-strength composite nonwovens with bacteriostasis, by changing to technique
Into being obviously improved fungistatic effect and the safety of non-woven fabrics.
The invention is realized by the following technical scheme：
A kind of high-strength composite nonwoven with bacteriostasis, preparation method includes the following steps：
（1）, prepare modified nano-titanium dioxide；
A, it is impregnated by nano-titanium dioxide and using the sodium hydroxide solution of 2mol/L, is stirred continuously in soaking process, then makes
Neutrality is washed to deionized water；
B, the nano-titanium dioxide after washing is impregnated using the acetic acid solution of 2mol/L, in soaking process, is shaken using ultrasonic wave
Processing 15-20min is swung, is dried at 50 DEG C, uses the silane coupling agent and nano-titanium dioxide of nano-titanium dioxide weight 0.5%
Mixing, grinding mix them thoroughly uniformly；It is first handled using acetic acid solution, the pole on nano-titanium dioxide surface can be improved
Property and absorption property promote the intensity and stability of combination using being reacted with coupling agent and subsequent chitosan；
C, take chitosan that the water of 5 times of its weight is added, it is 3-4 that glacial acetic acid is added dropwise into water and adjusts PH, and stirring dissolves chitosan,
Then by nano-titanium dioxide made of step b and chitosan solution by weight 1:4 mixing, ultrasonic vibration handle 15min, subtract
Pressure filters, and drying obtains modified nano-titanium dioxide；Due to the surface modification to nano-titanium dioxide, make it for polypropylene
Also there is good facilitation with the compatibility of polyethylene terephthalate.
（2）, spinning；
100 parts of polypropylene, 40 parts of polyethylene terephthalate drying are taken by weight, and step is added（1）The modification of preparation
1-3 parts of nano-titanium dioxide, use double screw extruder mixing, then spinning；
（3）, shredding；
By step（2）Spinning using opener carry out shredding mixing；
（4）, combing；
Spinning after shredding is combed；
（5）, lapping；
The spinning combed is subjected to lapping using lapping machine, arranges molding, using double roller calender spunbond, cooling winding.
The roll shaft temperature of the double roller calender is 140-150 DEG C.
In step（2）After spinning, 10 parts of spinning are added in the acetum of 100 parts of 1.2mol/L, then at 25 DEG C
Constant temperature impregnates 20min, and the ethyl acrylate ethanol solution 10 that mass fraction is 5% is added in the oxygen being passed through in nitrogen discharge system
Part, it stirs evenly, is slowly added to 0.015 part of potassium peroxydisulfate, is stirred in adition process with the speed of 500r/min, be heated to 65
DEG C, it being stirred continuously, reacts 50min, be cooled to room temperature, it is 8.5 that the sodium hydroxide solution that 2mol/L is then added, which adjusts solution PH,
Then by spin filter, it is washed to neutrality, dries, obtains modified spinning.
Step（5）The middle net that will first complete handles 60min at 60 DEG C, then reuses double roller calender processing.
The roller surface of the double roller calender has needle-shaped burr, and burr length is 0.1mm, can promote dissipating for roller surface
Thermal effect promotes the uniformity of non-woven fabrics, and burr can be to nothing so that ambient temperature is relatively uniform in roll-in
Woven fabric has the effect of needle thorn, can form intensity higher tie point on surface when roll-in, promote the intensity of non-woven fabrics, can
Further promote the bonding strength of non-woven fabrics.
Preferably, burr diameter is not more than 0.3mm.
Beneficial effects of the present invention：Non-woven fabric provided by the present application is using modified nano-titanium dioxide as antibacterial
Agent, in processing, in nano-titanium dioxide surface grafting chitosan, chitosan and titanium dioxide directly pass through hydrogen bond and coupling agent
Connection function, the intensity of connection is more preferable, can be obviously improved it is antibacterial, sterilization effect, meanwhile, in spinning, nano-silica
Change titanium due to having very big specific surface area, can be obviously improved and the combination of polypropylene and polyethylene terephthalate
Effect promotes the compatibility of material, promotes the intensity of spinning, and then is obviously improved the intensity of non-woven fabrics；In spinning in the application
Afterwards, modification has been carried out to spinning, has utilized under the action of catalyst micro- such as chitosan of ethyl acrylate and spinning surface
The polymerization of amount makes to generate crosslinking between spinning, makes to be crosslinked being obviously improved by force at node, although can be by portion in subsequent processing
Divide the fiber separation of crosslinking, still, the strength enhancing of material at crosslinking points can also enhance the intensity of non-woven fabrics, on the other hand, by
Mesh space structure can be generated after polymerization, after shaping, intensity can be also obviously improved.
The good antimicrobial effect of non-woven fabric of the invention, intensity is high, and not pilling in use process, service performance is good, leads to
Cross the modification to titanium dioxide and the adjustment of preparation process, by polypropylene with polyethylene terephthalate is compound draws
Silk, plays apparent synergistic effect, improves the comprehensive performance of non-woven fabrics.
