- US 3,318,990 describes a process for the production of viscose flat fibers in which, on the one hand, sodium carbonate and on the other hand a water-swelling high molecular substance, e.g. CMC, mixed. The result is a collapsed hollow cross-sectional structure.
- a water-swelling high molecular substance e.g. CMC
- the resulting fibers are described as being completely flat.
- the collapsed cross-sectional structure holds together even when wet.
- the fibers are suitable according to US 3,318,990 for the production of paper.
- the object of the present invention is to provide an adjuvant for producing papers, in particular specialty papers for achieving high dry strengths or a binder fiber for nonwovens, which are produced in a wet process.
- a regenerated cellulose staple fiber selected from the group consisting of
- B D ⁇ 5, preferably ⁇ 4.5, particularly preferably 3-4,
- a regenerated cellulose staple fiber selected from the group consisting of standard viscose fibers and solid flat fibers in short cut form (ie with a cut length of 20 mm or less) incorporating CMC is an excellent excipient for producing papers having improved strength is also excellent in the production of wet nonwovens.
- short cut is commonly used for fibers having a fiber length of 10 mm or less.
- short cut also includes fibers having a length of up to 20 mm.
- the short cut fiber according to the invention is selected from the group consisting of standard viscose fibers and solid flat fibers whose cross section has a ratio of width B to thickness D of B: D ⁇ 5, preferably ⁇ 4.5, particularly preferably 3-4.
- Standard viscose fibers have an irregular ribbed cross-section.
- solid flat fibers are meant, for the purposes of the present invention, fibers whose cross-section is a continuous cellulose matrix. This distinguishes these fibers from fibers resulting from the collapse of a hollow cross-sectional structure (as described, for example, in U.S. 3,318,990), which is detectable at the cross-section as well as at the rippled surface structure typical of massive flax fibers.
- massive flat fibers can be obtained by spinning a viscose through a nozzle having openings in the form of a narrow rectangular slit.
- the cross section of the solid flat fiber according to the invention has a ratio of width B to thickness D of B: D ⁇ 5, preferably ⁇ 4.5, particularly preferably 3-4.
- the cross section can be influenced in particular by the geometry of the spinneret opening.
- No. 3,318,990 A describes that only when the width / thickness ratio of a flat fiber is greater than 5 (in particular up to 10-20) is a significant increase in the paper produced from such fibers ascertainable.
- the binding of the CMC in the fiber according to the invention is stronger than in the case of fibers in which CMC is only subsequently coated onto the cellulosic fiber.
- the use of the insoluble fiber of the invention also results in less
- Viscose fibers with a proportion of CMC are known. It is a mixed fiber, which by the incorporation of carboxymethylcellulose in the
- Viscose spinning composition is obtained.
- Such fibers have also been produced commercially (US 4,199,367 A, US 4,289,824 A).
- a Viskosepinnmasse is prepared by the usual methods.
- the spinning mass is added immediately before spinning a 8-12 wt.% Solution of carboxymethyl cellulose (CMC), so that the desired storage amount based on underivatized cellulose results.
- Post-processing and drying are carried out by the usual methods.
- the proportion of incorporated carboxymethyl cellulose in the regenerated cellulose fiber is preferably 5% by weight to 50% by weight, more preferably 15% by weight to 40% by weight, most preferably 20% by weight to 30% by weight, based on underivatized cellulose ,
- the carboxymethylcellulose may be a commercial product having a degree of substitution DS of 0.6-1.2, preferably 0.65-0.85 and a viscosity (2% solution, 25 ° C.) of 30-800 mPas; preferably 50-100 mPas.
- the fiber titer of the fiber according to the invention is preferably from 0.5 dtex to 8 dtex, more preferably from 1.3 to 6 dtex.
- the cutting length of the fiber according to the invention is preferably 2 to 20 mm, more preferably 4 to 8 mm.
- the cellulose staple fiber according to the invention is outstandingly suitable as a binder fiber for products containing short cut fibers as well as for nonwovens, which are produced in a wet process, in particular as an auxiliary for the production of paper or
- Paper-like products such as tea bags, gas and fluid filters, security papers and decorative papers. Accordingly, the present invention also relates to a paper or paper-like product, such as tea bags, gas and Fluidf ⁇ lter, security paper, decorative paper containing the cellulase staple fiber according to the invention.
- the paper or paper-like product according to the invention preferably contains from 10 to 99%, particularly preferably from 15 to 45%, of the cellulosic staple fiber according to the invention.
- a standard viscose fiber is made by the usual methods. Of the
- Viscose spinning material is added immediately before spinning the amount of a 10% solution of carboxymethyl cellulose (CMC), so that there is a storage of, for example, 20-30% CMC on cellulose.
- Post-processing and drying are carried out by the usual methods; The fiber is cut inline to a length of 20 mm or less, especially 4-8 mm.
- the short-cut fibers can be used as special fibers directly in papermaking.
- a massive flat fiber can be made by incorporating CMC and spinning through a rectangular spinning aperture.
- Atro fibers or fiber mixture
- 300 liters of water Each 75 g of atro fibers (or fiber mixture) are dispersed for this purpose in 300 liters of water.
- the nonwoven is then placed on a screen belt at a defined take-off speed.
- nonwovens were produced with a basis weight of about 50 g / m 2 . All webs when wet showed a strength suitable for handling. The nonwovens were then dried without moving in air.
- Fleece A The fleece shows no appreciable strength in the dried state. It is not possible to handle the fleece without it decaying.
- Nonwoven in leaf shape to handle is
- Fleece B The fleece shows a much higher strength than the fleeces A and C.
- the use of the invention fiber in wet nonwovens thus allows the production of nonwovens with significantly improved dry strength.
- the fiber of the invention acts here as a binder fiber and thus allows a saving of other binders.

Abstract
La présente invention porte sur une fibre discontinue en cellulose régénérée choisie dans le groupe constitué par a) des fibres de viscose standard et b) des fibres plates massives dont la section transversale a un rapport de largeur B à l'épaisseur D de B:D < 5, de préférence < 4,5, de façon plus préférée de 3-4. Dans la fibre discontinue en cellulose, de la carboxyméthylcellulose est incorporée laquelle est caractérisée par une longueur de coupe de 20 mm ou moins. La fibre selon l'invention est appropriée comme adjuvant dans la production de papier ou de non-tissé.
