Definitions
- the invention relates to a cellulosic molding and to a process for producing cellulosic moldings by the dry-wet extrusion process with improved and extended functional effects, in particular for use in medicine, hygiene, clothing, papermaking and the packaging industry.
- the functional effect relates to a uniform and finely dosed bactericidal action, especially in wound dressings, sports and leisure clothing, hospital textiles, filter and packaging papers.
- heavy metal ions such as silver, mercury, copper, zinc and zirconium ions have a killing or growth-inhibiting effect on microorganisms such as bacteria, viruses, fungi and spores (Thurman et al., CRC Crit Rev. In Environ. Contr. 18 (4) , Pp. 295-315 (1989)).
- microorganisms such as bacteria, viruses, fungi and spores
- the silver ions are of particular interest.
- the decisive advantage of silver ions over other bactericidal metal ions, such. B. Hg 2+ is the most insensitive human metabolism to silver.
- the bactericidal concentration is given as 0.01- 1 mg / L in silver (Ullman's Encyclopedia of Industrial Chemistry (5th ed.), VCH 1993, Volume A 24, p. 160).
- the moldings are capable of adsorbing metals from heavy metal-containing media.
- the heavy metal loaded moldings can be used as antibacterial and / or fungicidal material.
- the content of adsorbed heavy metals in these cellulosic moldings is at least about 70 mg / kg, based on the total weight of the cellulosic molding.
- the invention has for its object to provide a cellulosic molded body and a method for the production of cellulosic moldings having a functional effect, especially for use in medicine, hygiene and clothing, which shows a bactericidal effect and this particular connects with the advantages of a breathable garment.
- Another object is to provide the active ingredients in a textile depot and to ensure a sufficient release of these substances from the depot over time.
- the drug concentration to be delivered should be controllable.
- the shaped bodies produced by the process according to the invention in particular fibers and films, are to be created in such a way that they are suitable for production as wound dressings, patches, hygiene articles, textiles, specialty papers and as packaging material due to their high adsorption capacity. Finally, composites of mixtures with other fibers should be produced.
- Weakly crosslinked ion exchangers for the purposes of the present invention are ion exchangers which are provided with a reduced proportion of crosslinking agents.
- Conventional ion exchange resins have a crosslinker content of 4 to 12% by weight, based on the mass of the exchange resin.
- Weakly crosslinked ion exchangers for the purposes of the present invention have a crosslinker content of 0.1 to 2.0% by weight, preferably 0.3 to 1.5% by weight, more preferably 0.5 to 1.2% by weight.
- Weakly crosslinked ion exchange resins are also characterized by the fact that they swell very strongly in aqueous solutions. Conventional ion exchange resins with the abovementioned crosslinker components have only low degrees of swelling.
- the fibers produced with incorporated weakly crosslinked cation exchangers exceed with their binding capacity for silver ions that of the brown algae according to DE 10 140 772 by up to 28 times. It is thus given the opportunity to produce fibers or films, the z. B. can be highly loaded with cationic bactericidal agents such as silver ions.
- a fiber with 15% by mass of incorporated weakly crosslinked cation exchanger can be loaded with about 80 g of silver. Silver loading of the fiber with> 100 g Ag / kg fiber is possible with a corresponding increase in the mass fraction of the incorporated weakly crosslinked cation exchanger.
- These fibers can then be prepared by mixing with other fibers, such as.
- fibers which have a sufficient content in terms of the silver content per fiber to a sufficient level show bactericidal effect, but show no disadvantages in terms of textile-physical parameters.
- Such fibers show a completely sufficient bactericidal action in the hitherto known fields of use and are equal in their textile-physical values to unmodified fibers. The processing of these fibers and yarns made from them is possible on all textile machines.
- a measure of the expected bactericidal effect of the fibers or yarns is the equilibrium concentration of the active ingredients in aqueous solutions such.
- the free Ag ions are stably discharged, whereby the equilibrium concentration is maintained over time by the Ag deposited in the fiber. Due to the increased depot effect of the fibers according to the invention thus the equilibrium concentration can be maintained over an increased period.
- the fibers can be loaded with cation-active and anionically active bactericidal ions, such as, for example, B. with silver ions and benzoic acid or sorbic acid.
- the loading of the functionalized fibers may conveniently be done by dipping in a solution with the appropriate ions. Diving can be done both in batch mode and continuously. In continuous dipping, preferably the cut fiber is loaded in a separate bath in the after-treatment.
- a 12% by mass cellulose solution in N-methylmorpholine N-oxide monohydrate is a powdered weakly crosslinked cation exchanger based on a crosslinked copolymer of acrylic acid and sodium with a particle size ⁇ 10 microns in a weight fraction of 15% by mass to a cellulose content added.
- This spinning solution is homogenized in a kneader and spun at a temperature of about 90 ° C through a spinneret with 480 holes and a nozzle hole diameter of 80 microns.
- the take-off speed is 30 m / min.
- the multifilament yarn is passed through several washing baths to leach the N-methylmorpholine-N-oxide.
- the fibers are spun off and loaded with 10 liters of a 0.1 M silver nitrate solution per kg of fiber material. After loading, the fibers are spun and washed free from adhering silver nitrate. Subsequently, the fibers are dried at about 80 ° C.
- Table 2 shows the fiber parameters and the silver content of the fiber.
- Such a highly loaded fiber has the advantage that by blending the fiber with other textile fibers such.
- Yarns produced in this way can be processed very well on knitting and knitting machines, in contrast to galvanized polyamide threads.
- Example 2 Fibers are spun according to Example 1 with a titer of 0.17 tex and a content of weakly crosslinked cation exchanger of 6% by mass, based on the cellulose content. These fibers are loaded according to Example 1 with silver ions. The fiber parameters are listed in Table 3.
- Example 3 Fibers are produced according to Example 1 with a titer of 0.5 tex and a content of weakly crosslinked cation exchanger of 0.5% by mass, based on the cellulose content.
- the loading with silver ions is carried out analogously to Example 1.
- the fiber parameters are shown in Table 3. In Table 3, a fiber without a weakly crosslinked cation exchanger was included for comparison.
- Example 4 (Comparative Example) To a cellulose mash in 60% aqueous N-methylmorpholine N-oxide is added an aqueous suspension of a weakly acidic macroporous cation exchanger based on a styrene-divinylbenzene copolymer with chelating iminodiacetic acid groups in such a concentration that the Spun fibers contain a content of 6% by mass based on the cellulose content. The fibers are washed after spinning and loaded as described in Example 1 with silver ions. Table 4 contains the fiber parameters.
- Example 5 Working analogously to Example 4 and gives the mash 6% by mass of a weak acid macroporous cation exchanger based on crosslinked polyacrylate in the sodium form, so that in the spun fiber 6% by mass related ion exchanger are included in the cellulose content, this fiber washes and charged with silver ions as described in Example 1, to give a fiber with 13.6 g Ag / kg fiber. It is surprisingly clear from example 5 that the polyacrylate-based ion exchanger absorbs less than half of silver ions than the slightly crosslinked polyacrylate-based cation exchanger.
- Example 6 Fibers with weakly crosslinked cation exchangers as well as conventional prior art ion exchanges prepared according to Examples 1 to 5 were loaded with silver, cupric and zinc ions. The results are shown in Table 5.
- Fibers loaded with copper ions, silver ions or with a combination of silver and zinc ions can be used as bactericidal fibers.
- Example 7 To a 11% by mass cellulose solution in N-methylmorpholine N-oxide monohydrate is added a suspension of a weakly crosslinked cation exchanger based on a crosslinked copolymer of acrylic acid and sodium acrylate and a strong base anion exchanger based on a styrene-divinylbenzene copolymer with trialkylammonium groups in chloride form in 85% N-methylmorpholine-N-oxide in such a concentration that the spinning solution 11 % By mass of cellulose and, based on the cellulose content, 8% by mass of the weakly crosslinked cation exchanger and 8% by mass of the anion exchanger.
- the spinning solution according to Example 1 is spun with a titer of 0.5 tex.
- the fibers have a tenacity of 26.3 cN / tex, an elongation of 12.1% and a fineness-related loop tearing force of 8.6 cN / tex.
- the silver loading is 52.4 g silver / kg fiber and the loading with benzoate is 16.6 g benzoate / kg fiber. These fibers have a very strong bactericidal action.
- the example demonstrates the suitability of the fibers of the present invention for combined use with prior art anion exchange and cation exchange loaded fibers.
- Example 8 Inventive ion exchanger fibers or films with incorporated cation exchangers prepared according to Example 2 are loaded with nicotine. The loaded fibers or films are washed and dried. These fibers or films can be processed into textile depots and used as transdermal therapeutic systems.
- Fibers prepared according to Example 1 were tested for their bactericidal action in accordance with the European Pharmacopaeia (EP 2002), Chapter 2.6.12, Bioburden determination.
- Papers containing fibers according to Example 1 were tested in an amount such that a gradation of the silver contents in the paper was 190 mg Ag / kg, 760 mg Ag / kg and 3800 mg Ag / kg paper.
- the test was carried out on the following microorganisms (Tables 6 - 9): Pseudomonas aeruginosa ATCC 9027 Staphylococcus aureus ATCC 6538 Bacillus subtilis spores ATCC 6633 Fusarium solani spores ATCC 36031.
- Example 10 Fibers made according to Example 1 were spun with cotton into stocking yarn having a denier Nm 68/1 and a silver content of 1300 mg Ag / kg yarn. From this yarn, a knitted tube was made and tested for bactericidal action (sample 31444083). The test was carried out in accordance with SN195924. The test organism was Lactobacillus brevis DSM 20054. The control sample used was non-antimicrobial cotton fabric (Table 10). In each case 5 measurements were carried out on the basis of the same sample material and the control sample.
- the 24-hour value of the growth control (control or standard tissue) must be at least two orders of magnitude above the initial value (AE ⁇ -2).
- An antimicrobial effect is given when a KBE value is at most 0.5 decimal logarithms above the mean of the zero-contact time CFU values, ie AE 524 > -0.5.
