Description

A kind of preparation method and applications of superabsorbency toughening carbassus
Technical field
The present invention relates to medical dressing technical fields, and in particular to a kind of preparation side of superabsorbency toughening carbassus Method and its application.
Background technique
In general, hospital gauze refers to white cotton yarn fabric and or having bored the polymeric membrane in hole with thermocompression bonding (thermocompression) mode is adhered to the absorbent cotton containing the short fibre of viscose glue (Viscose) and the product that generates.Aforementioned drift The technique of white cotton yarn fabric is not only complicated, but also is not easy to remove from injury, makes patient perceptions painful.Although only using degreasing The pain of patient can be mitigated when cotton and its absorbability can be made full use of, but be adhered to it is more difficult when the absorbent cotton of injury Removing.The gauze only formed by cotton needs to be covered with woven fabric or nonwoven fabric in its appearance since its stretching resistance is weaker.In addition, handle The polymeric membrane for having bored hole is adhered to the absorbent cotton containing short rayon fiber in a manner of thermocompression bonding (thermocompression) and gives birth to At product, although removing be easier to, its absorbability is weaker, and causes psychological burden to patient, sometimes it also occur that quiet Electricity, it may be said that problem is the more.So this invention address that the water absorbing properties and toughness of research gauze, improve gauze during surgery Practicability, allows to mitigate accordingly the pain of sufferer, while also can satisfy the use demand in terms of other medical treatment.
Summary of the invention
In order to solve the above technical problems, the present invention provide a kind of superabsorbency toughening carbassus preparation method and its Using this method, which is used, is configured to blend spinning for polyacrylonitrile, Sodium Alginate, hydroxyethyl cellulose powder and deionized water Liquid, then centrifugation, standing, removal precipitating, then carry out vacuum defoamation, are then added in wet-spinning frame through metering pump meter Amount, spinning head are precipitated in coagulating bath and are formed fiber filaments after extruding, and handle to obtain fabric using stretching, sizing, weaving, Obtained fabric is immersed again in the hot water storgae of desizing, scouring and bleaching combined machine and carry out HIGH TEMPERATURE PURGE and modification, finally impregnates modified fabric Carried out in the mixed liquor being made of vinyl chloride ethylene ester, ammonium citrate, chitosan, water it is twice-modified, and through open-width, dry To finished product gauze.The superabsorbency toughening carbassus being prepared, water absorbing properties are good, toughness is high, in medical conduct It has a good application prospect in industry.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of preparation method of superabsorbency toughening carbassus, includes the following steps：
(1) by polyacrylonitrile, Sodium Alginate, hydroxyethyl cellulose powder and deionized water according to 2:1:5:23 mass ratio It is mixed, is sufficiently stirred to form blend spinning liquid after ultrasonic disperse is handled, will then be stood after the centrifugation of blend spinning liquid Overnight, the sediment being filtered to remove in blend spinning liquid is spare；
(2) spinning solution is subjected to vacuum defoamation, be then added in wet-spinning frame, by measuring pump-metered, spinning head pressure Fiber filaments are precipitated and formed after out in coagulating bath, the coagulating bath is the mixing alcoholic solution of dimethyl acetamide, sodium sulphate, Wherein dimethyl acetamide, sodium sulphate, ethyl alcohol molar ratio be 3:10:55, it handles to obtain base using stretching, sizing, weaving Cloth, draw ratio are 6-8 times；
(3) obtained fabric is immersed in the hot water storgae of desizing, scouring and bleaching combined machine, sets bath raio as 1:20, first use 85-90 DEG C Water clean 45-55 minute, then water temperature is risen to 95-100 DEG C, modifying agent is added, modifying agent is 1- amine propyl -4-methylimidazole Tetrafluoroborate, alginate propylene glycol, glycerin diglycidyl ether, triazine bi-quaternary ammonium salt are according to 1:1:2:5 mass ratio institute The mixture of composition cleans 15-20 minutes；
(4) obtained modification fabric is soaked in the mixing being made of vinyl chloride ethylene ester, ammonium citrate, chitosan, water In liquid, the pH with dilute hydrochloric acid adjustment mixed liquor is 3.5-4.5, is impregnated 3-5 hours, then by the modification fabric clear water after immersion Washing to surface is neutrality, obtains twice-modified fabric through dehydration；
(5) by obtained twice-modified fabric through scutcher open-width, then drying machine drying and processing at 115-135 DEG C 35-45 minutes to get finished product carbassus.
Further, the frequency of ultrasonic disperse is 20-25kHz, ultrasonic power 200-300W in the step (1), is surpassed The sonication time is 30-40 minutes.
Further, the vacuum degree of vacuum defoamation is -0.08 to -0.1MPa in the step (2), inclined heated plate 40- 60 minutes.
Further, the coagulation bath temperature in the step (2) is 50 DEG C, and spinning temperature is 85-95 DEG C, orifice diameter For 0.5mm.
Further, the concentration of the modifying agent in the step (3) in water is 3-4g/L.
Further, the mass ratio of vinyl chloride ethylene ester in the step (4), ammonium citrate, chitosan and water is 2:3: 6:150
Further, the invention also discloses superabsorbency toughening carbassuses made from the preparation method in medical treatment Application in articles industry.
Compared with prior art, the present invention its advantages are：
(1) preparation method of carbassus of the invention is used polyacrylonitrile, Sodium Alginate, hydroxyethyl cellulose powder It is configured to blend spinning liquid with deionized water, then centrifugation, standing, removal precipitating, then carry out vacuum defoamation, be then added wet In method spinning machine by metering pump-metered, spinning head extrude after fiber filaments are precipitated and formed in coagulating bath, using stretch, Sizing, weaving handle to obtain fabric, then obtained fabric immersed in the hot water storgae of desizing, scouring and bleaching combined machine carry out HIGH TEMPERATURE PURGE and It is modified, finally modified fabric is soaked in the mixed liquor being made of vinyl chloride ethylene ester, ammonium citrate, chitosan, water and is carried out It is twice-modified, and finished product gauze is obtained through open-width, drying.The superabsorbency toughening carbassus being prepared, water imbibition Energy is good, toughness is high, has a good application prospect in medical supplies industry.
(2) present invention employs polyacrylonitrile, Sodium Alginate, vinyl chloride ethylene ester, ammonium citrate these types raw materials to participate in Carbassus is prepared, effective performance boost has been carried out to carbassus, although these materials are not applied to operation yarn for the first time In cloth, but the merging of amount group is aided with corresponding processing mode according to a certain ratio, brings to the carbassus being finally prepared Increasing substantially in service performance, this is never to report in previous research, for realizing that technology of the invention is imitated Fruit plays the role of conclusive.
