Abstract
The present invention relates to a chitin nonwoven fabric and its production method. It is made up by using chitin and adopting the processes of cutting, washing with water, drying, dissolving, curing, filtering, defoaming, spinning, drawing and coagulating, bonding to form net, washing with water and drying. Said chitin nonwoven fabric has soft hand feel, good moisture-retaining property and air permeability and good biological compatibility, and has the several medical effects of resisting bacterial, inhibiting bacteria, relieving inflammation and preventing infection, so that it can be extensively used for making medical dressing and artificial skin, etc.
Description
The technical field nonwoven fabric claims non-weaving cloth again, belongs to textile industry nonwoven (non-woven) field.The present invention relates to a kind of chitin nonwoven fabric and production method thereof.
The background technology chitin is used for fields such as medical treatment, health care, health, beauty treatment in recent years in a large number because good Bc and biologically active are arranged, and is called as the sixth-largest element of human body.At medical field, be a difficult problem to the treatment of large-area deep burn, scald and wound always, press for a kind of can accelerating wound, do not have the artificial skin of scar after must repeatedly not making skin graft and heal as far as possible.Through long term studies and clinical verification, chitin is optimal a kind of burn, scald and wound external application dressing at present.
At present, chitin dressing mainly contains two kinds of crust plasma membrane and chitin nonwoven fabrics.The crust plasma membrane is to add adhesive and other materials is made with the chitin powder, so in feel, moisture absorption is ventilative and have big defective aspect the excitant of wound; General chitin nonwoven fabric then is after chitin is manufactured the fiber that meets the processing request of weaving, and is consolidated into cloth shape material through no spinning process (as needle point method, water acupuncture manipulation etc.) again.
Summary of the invention the objective of the invention is to propose a kind of one-step method continuous producing method of chitin nonwoven fabric, another object of the present invention provide a kind of with spinning, drawing-off, stickingly twine, be frozen into the chitin nonwoven fabric that technology such as net is made with premium properties.
The object of the present invention is achieved like this: propose a kind of production method of chitin nonwoven fabric, described method comprises the steps:
1) at first chitin section is washed, dry, be dissolved in and contain lithium chloride (LiCl)--in-dimethylacetylamide (DMAC) solution, make certain density glue, through slaking filtration, deaeration, make spinning solution again.
2) spinning solution is by spinning plate (spinning aperture 0.04-0.20mm, the spinneret orifice order is counted the 110-400 order) extrude the back and in the spinning container, promptly stretched and solidify by the solidification liquid of certain flow rate (100-400m/min), and be injected into an online face of proal holder that micropore is arranged.Sprinkler design becomes teeter formula motor pattern, and the direction of motion is perpendicular to the machine orientation, parallel crisscross motion, and hunting frequency is directly proportional with speed of production.By this design, the chitin fiber silk is at the holder of motion lay in length and breadth on the net, and the fiber net structure that is formed by stacking is tight, and is even to brute force in length and breadth, surfacing.3) since this moment the chitin fiber silk also do not solidify fully and still have viscosity, under the active force of absorption affinity of holding in the palm off the net suction wind and injection solidification liquid, the mutual bonding mat of these fibers has just formed the net flaky material, again through solidify, wash, dry chitin nonwoven fabric.Described technological process is as follows: chitin section → washing → dehydration → drying → dissolving → filtration → maturation → filtration → deaeration → spinning → stretching is solidified → is glued and twines → be frozen into net → wash → dry → reel → cut → pack warehouse-in.
This chitin nonwoven fabric production method that the present invention proposes, its advantage is that fiber production and nonwoven fabric two road manufacturing processes are united two into one, not only shortened process and simplified production method greatly, reduce production costs, and no longer pass through technologies such as fiber opening, combing, reduced the difficulty that fiber is made.Less demanding to the continuity of spinning simultaneously, long filament, short silk or fracture of wire all do not influence the formation of nonwoven fabric, have reduced the difficulty of technology controlling and process.
Another object of the present invention is achieved in that it is that chitin section is solidified, glued and twine, be frozen into the chitin nonwoven fabric material that operation one-step method such as net, washing, oven dry make continuously by washing, drying, dissolving, slaking filtration, deaeration, spinning, stretching that a kind of chitin nonwoven fabric, described chitin nonwoven fabric are provided.Product grammes per square metre scope 25～60g/m
2, fibre fineness 0.8～6dtex, have soft, preserve moisture that air permeable effect is good, good biocompatibility, can produce the hydrophilic gel material in the wound, prevent that bacterium from passing through, antibacterial, anti-inflammatory, effect such as protect from infection.Be widely used in making the chitin medical dressing, as chitin artificial skin, the dressing of chitin medical bio or the like.

The invention will be further described below in conjunction with preferred embodiment of the present invention for the specific embodiment.
Embodiment 1
At first chitin section washed, after the drying, be dissolved in and contain in lithium chloride (Licl)-dimethylacetylamide (DMAC) solution, make chitin concentration and be 15% glue, through slaking filtration, vacuumizing and defoaming, make spinning solution again.It is that the normal temperature attitude alcohol solidification liquid of 240m/min stretches and solidifies by flow velocity promptly in spinning funnel that spinning solution is extruded the back by aperture 0.12mm, the several 110 purpose spinning plate of hole order, and is injected into above the proal holder net (Air permenbility is 240cfm) that micropore arranged.The hunting frequency of shower nozzle is directly proportional with speed of production.The chitin fiber silk did not also solidify fully and still had viscosity this moment, under the active force of absorption affinity of holding in the palm off the net suction wind and injection solidification liquid, the mutual bonding mat of these fibers has just formed the net flaky material, again through solidify, wash, dry chitin nonwoven fabric.
Making concentration by the method for embodiment 1 is 8% chitin spinning solution, extruding the back by aperture 0.10mm, the several 220 purpose spinning plate of hole order then is that the normal temperature attitude alcohol solidification liquid of 200m/min stretches and solidifies by flow velocity in spinning funnel, and be injected into above the proal holder net (Air permenbility is 240cfm) that micropore arranged, again under the active force of absorption affinity of holding in the palm off the net suction wind and injection solidification liquid, the mutual bonding mat of these fibers has just formed the net flaky material, again through solidify, wash, dry chitin nonwoven fabric.
