Description
Technical field
The present invention relates to Cellulosed molded article and a kind ofly make the method for Cellulosed molded article by dry type-wet method, described Cellulosed molded article has the functional effect improved, especially can be applicable in medicine, health, clothes, papermaking and the packaging industry.
Described functional effect is at one stable and can be through the fungicide effect of careful adjusting, especially for the fungicide effect of wound contact material, motion and Casual Wear, hospital's textiles, filter and wrapping paper.
Background technology
As everyone knows, heavy metal ion (for example silver, mercury/mercury, copper, zinc and zirconium ion) makes bacterium, virus, fungi or spore dead or suppress its growth (people such as Thurman, CRC Crit.Rev.In Environ.Contr.18 (4), 295-315 page or leaf (1989)).About fungicide effect, silver ion is especially interesting.Silver ion is better than other bactericide metal ion (Hg for example
2+) significant advantage be the insensibility of human metabolism to silver.The bactericide activity of silver is expressed as 0.01-1mg/l (Ullman ' s Encyclopedia of Industrial Chemistry (the 5th edition), VCH1993, A 24 volumes, the 160th page).
This effect of silver ion is used for different application.In the manufacturing of textile fabric, for example with the surface of silver-colored electro-deposition in polyamide filament.The problem that is treated as of the described electrosilvering polyamide filament on braiding machine and the moulding press because the silver layer of described polyamide filament partly is deposited on the feed carrier, causes described device repeatedly to shut down.Further known argent, silver-zeolite or silver-glass ceramics is introduced as the fibre substrate of the melt-spun fibre of polypropylene fiber, polyester fiber and polyamide fiber in (Taschenbuch f ü r die Textilindustrie 2003, Schiele with
Berlin, the 124ff page or leaf).
The use of silver-zeolite or silver-glass ceramics also proposes to be used for acrylic fibers.Having antibacterial and cellulose fibre bactericidal property can buy on market.Triclosan (2,4,4-trichlorine (II)-hydroxyl is stretched phenyl ether) incorporated into cause permanent antibacterial fiber (ITB International Textile Bulletin 3/2002) in the cellulose fibre.Described material is effective to the bacterium (comprising pathogenic staphylococcus aureus type) that is present in usually on the skin.
DE 10 140 772 discloses a kind of manufacturing and has the method for the Cellulosed molded article of the algae of having incorporated into.Described form can be from containing the medium absorption metal of heavy metal.The form that is mounted with heavy metal can be used as antibiotic and/or the antifungal material.The content of adsorbed heavy metal is with relevant with the gross weight of described Cellulosed molded article given at least about 70mg/kg in the described Cellulosed molded article.
It further discloses by having with fibre weight and counts the fiber impregnation of brown alga content of 11.39 weight % in 0.05M AgNO
3Obtain the silver content of every fiber 1855mg/kg in the solution.Because algae is a natural products, so in conjunction with the ability difference of described heavy metal.During being attached to heavy metal on the algae, different binding mechanisms are relevant, as ion-exchange, complexing and other principal reaction not.Therefore, it is nonspecific described heavy metal being attached on the described algae.Another advantage of described fiber is that only CATION can be used for bactericidal effect, and does not have the sterilization anion, for example benzoic acid and sorbic acid.
WO 00/63470 relates to the method that a kind of manufacturing has the Cellulosed molded article of high absorption capacity, wherein will have＞=the conventional ion exchange particle of the granularity of 25 μ m adds the described form by the preparation of Lyocell (Lyocell) method to.In addition, disclose the anionite that uses styrene diethylene benzene copoly mer, absorption with heavy metal (meaning is copper and lead) of the capacity of 0.01mmol/g.
The abridgments of specifications of Japan of JP 3054234 the 0152nd edition the 01st (C-0834) number discloses and comprises the manufacturing that ion-exchanger is functional, be suitable for the cellulose composition of the adhesive of making metal ion, and wherein said manufacture method is mixed, then solidified described mixture by the cellulose with specific generation and forms with an anionic polymer.
Summary of the invention
The purpose of this invention is to provide a kind of Cellulosed molded article and a kind of method for preparing described Cellulosed molded article with functional effect, described Cellulosed molded article is particularly useful in medicine, health and the clothes, and wherein said form has a fungicide effect and wherein especially described advantage is approved of breathable garment.Another purpose is the enough release that remains on described activating agent in the textiles sediment and further obtain described activating agent from described sediment in a period of time.The release concentration of described activating agent should be controllable.In addition, form, especially fiber that can obtain by the inventive method or paper tinsel should be so that it be because high absorption capacity of activating agent is applicable to the mode of preparation wound covering thing, Bandaid (band-aid), health product, textiles, dedicated paper and packaging material forms.At last, should make the compound that comprises different fibers.
Other advantage shows in following description.
Make up above-mentioned discussion according to the inventive method, reach described purpose by the feed-in Cellulosed molded article, wherein said form is according to dry type-wet type pressing method spinning and have a weak connection cation activity ion-exchanger of having incorporated into with activating agent.It is shocking that we find that the binding ability of described activating agent depends on the crosslinking degree of ion-exchanger.Therefore, if use by the weak crosslinked polyacrylate of polyfunctional crosslinking agent, so for example the binding ability of Yin cationic active agent can increase by the amount more than twice.
Weak cross-linking ion exchanger according to the present invention is the ion-exchanger with the cross-linked dosage that has reduced.Conventional ion exchanger resin shows the cross-linked dosage in 4 to 12 weight % of the weight of described ion-exchanger resin.Weak cross-linking ion exchanger according to the present invention has between 0.1 to 2.0 weight %, is preferably 0.3 to 1.5 weight %, especially is preferably the cross-linked dosage of 0.5 to 1.2 weight % scope.
Weak cross-linking ion exchanger resin is characterised in that the remarkable ability that significantly expands in the aqueous solution.Conventional ion exchanger resin with above-mentioned amount crosslinking agent only shows the expansion of less degree.
The fiber made from the weak cross-linked cationic exchanger of having incorporated into shows the ability in conjunction with silver ion, and it surpasses ability according to the fiber with brown alga of DE 10 140 772 up to 28 times.Therefore, give an opportunity and make fiber or the paper tinsel to load in a large number as the cation activity bactericide of silver ion.Fiber with weak cross-linked cationic ion-exchanger of having incorporated into of 15 weight % can load about 80g silver.If correspondingly increase the amount of the weak cross-linked cationic exchanger of having incorporated into, the silver-colored load greater than the 100gAg/kg fiber of fiber is possible so.
The concentration of bactericide metal ion and/or anion active agent can be that every kg Cellulosed molded article 0.005g is in the scope of 100g.
Can will be mounted with the fiber of bactericide metal ion and/or anion active agent and textile fabric fusion and be processed into the material that area has been measured.
Described fiber can with other mixed with fibers, for example cotton, wool or synthetic fiber have the yarn of the silver content of being wanted with generation.This program allows the sterilization yarn to make with very economical method.
Described textile fabric is selected from the group that comprises cotton, wool, polyester fiber, polyamide fiber, polyacrylic fibre (polyacryl-fibers), polypropylene fibre and cellulose-regeneratfasern (cellulosic synthetic fiber).Cellulose-regeneratfasern especially refers to by the fiber that newly makes after the artificial treatment of cellulose (cellulose) by for example extrusion process of dissolving.
The material that a kind of area has been measured to small part comprises Cellulosed molded article.The material that utilizes this area to measure can be made into paper.The material that utilizes this area to measure can be made into the sausage packing.The material that utilizes this area to measure can be made into non-woven product.Yet incorporating into described intrastitial increase of ion-exchanger causes adverse effect to textiles physical parameter (as intensity, percentage elongation and loop strength).Specifically, intensity and loop strength reduce with the increase of the ion-exchanger of incorporating into.
Therefore, provide the fiber that loads silver also to have economic interests, described fiber shows and the approaching textiles physical property of character that does not contain the fiber of the ion-exchanger of having incorporated into, as intensity and loop strength.
Can obtain the fiber that every fiber has to be enough to show the silver content of enough fungicide effects and not to have unfavorable part in view of the textiles physical parameter by the present invention.According to the present invention, the weak cross-linked cationic exchanger of incorporating into of 0.5 to 1.5 weight % of cellulose meter that can fiber is in conjunction with 5000 to 10,000mg Ag/kg fiber.Described fiber has enough fungicide effects and it equals the not fiber of upgrading with regard to its textiles physical parameter in the known use field.Described fiber can be processed and by its yarn of making on various weaving looms.
Based on using ion-exchanger, obtain fiber suitable on its fungicide effect if described in DE 19 917 614, replace weak cross-linked cationic exchanger so in conjunction with the carboxyl of acrylic acid-divinylbenzene-copolymer or based on imino group-oxalic acid in conjunction with the formation chelate of styrene-divinylbenzene-copolymer.Yet the capacity of silver ion is less than 50% of above-mentioned weak cross-linked cationic exchanger.
A measurement to the fungicide effect of described fiber or yarn is the equilibrium concentration of activating agent in the aqueous solution, for example concentration of silver ion.
For this purpose, fiber or the yarn that is mounted with silver ion is put in 20 ℃ of distilled water under the temperature, then after 24 hours, measures the equilibrium concentration of silver ion.Silver ion equilibrium concentration when table 1 show to use weak cross-linked cationic exchanger or known and ion-exchanger that divinyl-benzene is crosslinked and the snow cover carrying capacity in the fiber.As shown, the equilibrium concentration of silver ion is to obtain the 0.01 required level that arrives more than the concentration of 1mg/l of fungicide effect.Can described equilibrium concentration be controlled to each by mixed with fibers and want concentration level with other kind.
Table 1
| The content 7 weight % of ion-exchanger | The Ag content [g/kg] of fiber | Equilibrium concentration [mg/l Ag +] |
| Have-ion-exchanger of COOH-group | 13.5 | 2.9 |
| Ion-exchanger with chelation group | 17.5 | 3.6 |
| The weak cation-exchanger (the present invention) that connects | 36.5 | 2.7 |
Obtain the required equilibrium concentration of antibacterial effect when as shown in fig. 1, fiber according to the present invention is provided under the Ag content that has increased of fiber.Its advantage is conspicuous.
During using fiber, for good and all discharge free Ag ion, keep equilibrium concentration by the Ag that is deposited in the fiber whereby.Owing to the storage properties of having improved of fiber of the present invention, described equilibrium concentration can be kept the time of an elongated segment.
If will incorporate in the fiber based on the weak cross-linked cationic exchanger and the strongly basic anionite of the styrene-divinylbenzene-copolymer of trialkyl ammonium with chloride form, so described fiber can load cation activity and anion active bactericide ion, as silver ion and benzoic acid or sorbic acid.
Therefore, silver ion can be used with the anion active agent as benzoic acid and sorbic acid.As shown in some open cases, described material on toxicology be can not oppose and therefore its qualified is directly used in the food (
Sterilisation, Desinfektion, Konservierung, the 4th edition, 1988 time, the 396th page).Processing in the papermaking described fiber or provide antimicrobial packaging by its paper tinsel of making for food.
In addition, the described functional fiber with cationic active agent can be used in the medical application.Described fiber can be in conjunction with the reagent as nicotine (nicotine).Described fiber can be made Bandaid and be used for therapy system through skin.
The favourable loading of described functional fiber can be by carrying out described fiber impregnation in suitable ion solution.Described dipping can be continuously or the mode of batch mode carry out.When flooding, preferably during processing subsequently, staple fibre is loaded in the individual slots with continuous mode.
The specific embodiment
The present invention and its characteristic will be illustrated more clearly in by following example:
Example 1
With based on the copolymerzation with cross-linking compound of acrylic acid and sodium acrylate, have less than cross-linked cationic exchanger a little less than the powdery of the granularity of 10 μ m and add 12 weight % cellulose solutions in single hydration N-methylmorpholine-N-oxide in 15 weight % part by weight of cellulose ratios.This spinning solution is homogenized in a kneader and under about 90 ℃ temperature, come spinning with a spinneret (spinning nozzle) with spinneret orifice diameter of 480 holes and 80 μ m.Draw speed is about 30 meters/minute.The guiding multifilament passes the poor N-methylmorpholine-N-oxide with eccysis remnants of several washings.Described fiber is skidded and be loaded in the 0.1M liquor argenti nitratis ophthalmicus of every kg of fibers 10L.Behind loading, described fiber is skidded and wash to remove remaining silver nitrate.At last, described fiber is dry under about 80 ℃ temperature.
Table 2
| Yam count dtex | 0.7 |
| Anti-open tearing property (drying) cN/tex relevant with yam count | 22.5 |
| Percentage elongation (drying) % | 14.8 |
| The tear resistance cN/tex relevant with yam count of coil interweaves | 7.5 |
| Silver content g/kg fiber | 80 |
The parameter of table 2 display fibers and the silver content of every fiber.Highly the fiber of Zhuan Zaiing provides the advantage that can obtain to load silver-colored yarn economically by with this fiber and other textile fabric fusion of for example cotton.For the content of about 5000mg Ag/kg yarn, silver-colored fiber is only formed ten sixths of yarn.
Form contrast with the polyamide fiber of having electroplated, therefore the yarn of making shows good machinability on braiding machine or moulding press.
Example 2
Make the fiber that has the fiber number of 0.17tex and count the weak cross-linked cationic exchanger content of 6 weight % with content of cellulose according to example 1.According to example 1 these fibers are loaded silver.The fiber parameter provides in table 3.
Example 3
Make the fiber that has the fiber number of 0.5tex and count the weak cross-linked cationic exchanger content of 0.5 weight % with content of cellulose according to example 1.Carrying out silver ion according to example 1 loads.The parameter of described fiber is shown in the table 3.In addition, in table 3, show do not have the fiber of weak cross-linked cationic exchanger to compare.
Table 3
| Example 2 | Example 3 | The fiber that does not have weak cross-linked cationic exchanger | |
| Yam count dtex | 0.17 | 0.5 | 0.5 |
| Anti-open tearing property (drying) cN/tex relevant with yam count | 35.8 | 37.6 | 38.1 |
| Percentage elongation (drying) % | 13.0 | 11.4 | 11.8 |
| The tear resistance cN/tex relevant with yam count of coil interweaves | 8.2 | 9.1 | 9.5 |
| Silver content g/kg fiber | 36.6 | 4.6 | - |
Can be apparent that via the content of weak cross-linked cationic exchanger from example 1 to 3 and can regulate silver content on the fiber on a large scale.Even can obtain the high silver content of 0.5 weight %.0.5 the weak cross-linked cationic exchanger of weight % is small to the influence of the textiles parameter of fiber.
Example 4 (case of comparative examples)
To so that reaching in the concentration of the content of 6 weight % of content of cellulose, spinning fibre add cellulose slurries in 60% moisture N-methylmorpholine-N-oxide to based on the aqueous suspension of the faintly acid macroporous cation exchanger of the styrene-divinylbenzene-copolymer of chelate group with iminodiacetic acid.After spinning, load silver ion with described fiber wash and according to example 1.Table 4 shows the parameter of described fiber.
Table 4
| Example 4 | Example 5 | |
| Yam count dtex | 0.5 | 0.5 |
| Anti-open tearing property (drying) cN/tex relevant with yam count | 31.2 | 30.9 |
| Percentage elongation (drying) % | 14.2 | 13.5 |
| The tear resistance cN/tex relevant with yam count of coil interweaves | 9.1 | 8.5 |
| Silver content g/kg fiber | 17.5 | 13.6 |
Example 5 (case of comparative examples)
Add described slurries to corresponding to example 4 operation and with the faintly acid macroporous cation exchanger of 6 weight % based on the crosslinked polyacrylate of na form, so that spinning fibre contains the ion-exchanger of counting 6 weight % with content of cellulose, with described fiber wash and according to example 1 it is loaded silver ion, the operator obtains the fiber that every fiber has 13.6g Ag/kg.Example 5 shows surprisingly with the weak cross-linked cationic exchanger based on polyacrylate to be compared, based on the ion-exchanger of polyacrylate in conjunction with the silver ion of half amount approximately.Binding ability raising more than 100% causes advantage technical and economically, because on the one hand, a small amount of weak cross-linked cationic exchanger in the fiber influences the textiles physical parameter hardly, and on the other hand, height based on silver ion is incorporated into, is possible by the economical production with other fiber fusion.
Example 6
The fiber of the conventional ion exchanger with weak cross-linked cationic exchanger and prior art that will make according to example 1 to 5 loads silver, copper (II) and zinc ion.The results are shown in the table 5.
Table 5
The fiber that is mounted with the combination of copper ion, silver ion or silver ion and zinc ion can be used as the bactericide fiber.
Example 7
To so that containing the amount of the described anionite of the weak cross-linked cationic exchanger of the cellulose of counting 11 % by weight with content of cellulose, 8 % by weight and 8 % by weight, spinning solution add 11 % by weight cellulose solutions in the single hydration methyl morpholine of N--N-oxide with one to based on the weak cross-linked cationic exchanger of the copolymerzation with cross-linking compound of acrylic acid and PAA with based on the suspension of strongly basic anionite in N-methylmorpholine-N-oxide of the styrene diethylene benzene copoly mer of the trialkyl ammonium with chloride form. After homogenizing, spinning solution is carried out spinning to have the fiber number of 0.5tex according to example 1.The tear resistance of the 8.6cN/tex relevant of the intensity of described fiber demonstration 26.3cN/tex, 12.1% percentage elongation and coil with yarn.
Silver is loaded as 52.4g silver/kg fiber and benzoate is loaded as 16.6g benzoate/kg fiber.These fibers have very strong fungicide effect.Example shows according to fiber of the present invention and the applicability that is mounted with the fiber combinations of known anionite of prior art and cation-exchanger.
Example 8
