Adopt this programme can embody following superiority: 1. the functional of fiber is to obtain by the inorganic salts with function are added.In order to solve the functional single problem of functional fibre, this programme has added three kinds of function inorganic salts, it is multiple functional that fiber is had, these three kinds of inorganic salts are respectively the efficient bacteriostatic agent c of a anion emission agent b far infrared cast charges, because these three kinds of inorganic salts add among the fiber simultaneously, make fiber have the bactericidal effect simultaneously and to the effect of human body beneficial's far infrared and anion emission function; 2. general bacteriostatic fiber only has inhibitory action to negative bacterium such as Escherichia coli, positive bacteria such as gold-coloured staphylococci, and fungi such as Candida albicans are lacked bacteriostasis.This programme uses the Ag+ bacteriostatic agent content of high-load 6.5%, and the fiber that so just makes this programme can reach more than 99% to the inhibitory action of Candida albicans; 3. carry out spinning among above-mentioned three kinds of inorganic salts being dissolved in spinning melt, make the inorganic salts in the fiber can not lose its function, thereby make the fiber function sustained; 4. this programme demonstrates fully the health care of fabric, has multi-functional, safe, efficient antagonistic property.Its bacteriostasis rate is up to more than 95%, and the emissivity of far infrared is more than 85%, the anion emission rate 7000/(see examining report) more than the cm3.Three kinds of function inorganic salts combinations are all formed with nanometer grade powder, and are solved the dispersiveness of each component in high polymer by technology, have avoided the melten gel particle in the spinning melt to produce.The activation characteristic that has so not only fully shown small size, bigger serface can make the effect performance of each function more abundant again, can carry out smoothly through melt spinning.
Description of drawings:
Fig. 1 is the efficient antibacterial master batch manufacture craft process flow diagram flow chart of this programme multifunctional nano.
Fig. 2 is the efficient bacteriostatic fiber spinning technique of a this programme multifunctional nano process flow diagram flow chart.
The specific embodiment:
● three kinds of function inorganic salts formula combination that the fiber of this programme adds:
1. far infrared cast charge: nanoscale zirconia 45%, titanium dioxide 55%, silylation coupling agent (account for above substance weight 3%);
2. anion emission agent: nanoscale tourmaline powder 75%, titanium dioxide 25%, silylation coupling agent (account for above substance weight 3%);
3. efficient bacteriostatic agent: Ag+6.5%, titanium dioxide 93.5%, silylation coupling agent (account for above substance weight 3%);
4. oxytolerant agent: B215 among the PKB (Switzerland's trade names);
5. organic dispersing agent: high-molecular polythene.
● this programme improvement and innovative point are:
1. have multi-functional in order to reach fiber, this programme is through studying efficient far infrared cast charge, efficient anion emission agent and efficient bacteriostatic agent, be respectively 2%, 2%, 1.5% in its ratio in fiber, add in the spinning melt and carry out spinning, purpose is that the inorganic salts that content is many can be compatible with spinning melt fully; Selected the particle surface finishing agent of suitable silylation coupling agent, impelled inorganic salts and macromolecule to carry out interfacial reaction as inorganic salts; The function inorganic salts can not separated out in washing use, thereby to keep the multifunctionality of fiber, make the fiber function more lasting.
2. contain a spot of Ag+ in the fiber and will be difficult to suppress fungi, and the Ag+ of vast scale is difficult to join in the high polymer and goes.This programme adopts non-crystal cotton-shaped titanium dioxide as the implantation bed of Ag+ and add, and has solved the adding problem of vast scale Ag+, has reached the inhibition effect of fiber to fungi.
3. the use of nano material:
This programme uses the inorganic salts nano material, and the small size of nano material, bigger serface reflect the activity that it is bigger, have brought into play the functional of multifunctional inorganic salt fully.The adding of less ratio just can obtain big effect.But use nanometer particle to add in the spinning melt and just have the difficulties in dispersion problem.This programme takes various particles to handle separately, promptly handles with surface conditioning agent, does dispersant with a pulvis again, and agent is to be that the master is that dispersion is tentatively disperseed with titanium dioxide with the tourmaline as anion emission.And then add high-molecular polythene again as the melt dispersant before sneaking into melt, and then make spinning melt.Through as above handling nanometer grade powder and twice dispersion separately, then can there be gel particles and dispersed fabulous melt, help normally carrying out of spinning.
4. the master batch method is produced multifunctional fibre:
As the master batch method is multifunctional inorganic salt to be dispersed at first (PP, PET or PA) makes master batch in a small amount of carrier, and then by fixed than going to carry out spinning in the melt that mixes spinning.So not but increase melt and disperse and can carry out less volume and more variety according to market demand and arrange production.
● determining of multifunction safety efficient nano-antiseptic master batch manufacture craft parameter:
1. the activation that dewaters of efficient antibacterial formula combination (J) and high-strength anion and far infrared cast charge (F) high temperature:
Temperature: 140 ℃-160 ℃;
Time: 3～6h;
J∶F＝1∶2。
Temperature height, overlong time have the component caking; Temperature is low, and the too short pulvis dehydration deficiency that then can make of time does not reach the activation purpose.
2. can recipe ingredient surface treatment (height stirs processing):
Temperature: 140 ℃ ± 5 ℃;
Finishing agent: silylation surface conditioning agent;
Height stirs revolution: 4000rpm;
Time: 20 minutes.
The same temperature 1. of temperature; The finishing agent addition is crossed conference and is caused the pulvis bonding, and height stirs the revolution deficiency, and too short meeting of time causes the pulvis caking, disperses irregular.
3. the adding of polymer support (low speed adding high-speed stirred):
Temperature: on the high polymer softening point, be lower than 40 ℃-50 ℃ of high polymer fusing points;
Low speed: 200rpm;
At a high speed: 4000rpm;
Time: 20 minutes.
Temperature is crossed the low activation that can reduce pulvis, and the too high meeting of temperature makes high polymer near fusing point, influences pulvis and disperses.It is uneven in the stirring of low speed short time pulvis to be disperseed.
4. high-speed stirred adds organic dispersing agent and heatproof oxytolerant auxiliary agent dispersant:
Choose high-molecular polythene,
Temperature: be higher than 10 ℃ of dispersant flux fusing points;
Time: 5～7 minutes;
Promoter addition: high polymer weight * (3～5%).
Its fusing point of macromolecule dispersing agent polyethylene is about 114 ℃, and melting temperature adopts dispersant fusing point+10 ℃.
Temperature is too high, and overlong time dispersant viscosity is low excessively, and then parcel is uneven; Otherwise viscosity is too high, and the high polymer section can't be wrapped up.Promoter addition is very few, and the loss of polymer viscosity is excessive; Otherwise polymer is easy to change.
5. twin-screw temperature:
The twin-screw temperature is generally got high polymer fusing point+(10-15 ℃);
Low excessively slivering (granulating), pulvis and the auxiliary agent dispersion inequality of being unfavorable for of temperature.
● determining of multifunction safety efficient nano-antiseptic fiber manufacture craft parameter:
1. spinning temperature:
Spinning temperature is than low 8-15 ℃ of conventional spinning temperature;
The general high polymer fusing point that adds pulvis and auxiliary agent is lower than 8-10 ℃ of conventional spinning high polymer temperature
Cross and exceed low spinning temperature and all can influence the spinning melt flowability, cause difficulty in spinning.
2. spinning cooling condition:
Wind speed, blast are a little less than conventional spinning;
Rheumatism, wind-warm syndrome are higher than conventional spinning;
Because it is lower a little less than conventional high polymer enthalpy to contain pulvis high polymer fusing point, the quickening cooling can influence spinning and stretch oneself and yawn.
3. spinning one, two road finishes:
Spinning one, two road finishes should be a little more than about 5% of conventional spinning;
It is stronger to contain the pulvis polymer water absorbent, and profit is low can be influenced spinning and stretch oneself and yawn moulding with POY.
● the operation principle of this programme is three kinds of function inorganic salts are given simultaneously that it to be possessed among a kind of fiber multi-functional more comprehensively to promote the body-care effect.
1. efficient antibacterial its principle is many to be free with the extremely strong Ag+ of activity, when it arrived electronegative microbial cell, both firmly adsorbed owing to Coulomb attraction, and Ag+ enters cell through cell membrane and reacts with " SH ", destroy the activity of cell synzyme, cell is lost the division growth ability and death.(seeing examining report).
2. nanoscale anion inorganic salt has the function (7000/more than the cm3) of the high-strength anion of emission.After human body is accepted, reach activation blood, relieving fatigue, the neuro vegetative effect of balance.The suction of anion causes the human-body biological effect, regulates nervous centralis and automatic nervous system.Regulate corticocerebral function the circulatory system is had good improvement effect.Because the existence of anion, then adsorbable stink improves environmental condition.
3. the formula combination of far infrared and inorganic salts can be launched the far infrared of the absorbent 2～14um of human body.
More than three kinds of nano grade inorganic salt functional formula combination, be dispersed in the high polymer carrier by concrete technology, make master batch.Master batch quantitatively is dispersed in again makes the high poly-melt of function in the high polymer.By special spinning technique, it is that multi-functional raising oneself slightly entirely to fiber, POY is that multi-functional preorientated fiber, HOY are that multi-functional orientation fibers, DTY are the multifunction safety efficient nano-antiseptic elastic fibers that high-speed spinning becomes functional fibre FDY again.For the spinning fabric enterprise new function fabric of exploitation provides good textile raw material.
