Definitions

  • the present invention relates to a method for the production of polysaccharide fibers which contain a mixture of cellulose and ⁇ (1 ⁇ 3)-glucan as a fiber-forming substance, as well as to the fibers made thereby, and to their use.
  • Polysaccharides are becoming increasingly important, as they are materials that can be obtained from renewable raw materials.
  • One of the most frequently occurring polysaccharides is cellulose.
  • Cotton fibers, which consist almost exclusively of cellulose, are an example of the significance of polysaccharides.
  • materials obtained from other cellulosic raw materials e.g., cellulosic synthetic fibers, are continuing to gain in importance.
  • viscose fibers and “modal fibers” were assigned by BISFA (the International Bureau for the Standardization of Man-made Fibers) to cellulose fibers produced through chemical derivatization of cellulose with the help of aqueous sodium hydroxide solution and carbon disulfide.
  • modal fiber is a generic term which, as defined by BISFA, stands for a cellulose fiber having a defined high wet strength and an also defined high wet modulus (i.e., the force required to produce an elongation of the fiber of 5% in its wet state).
  • BISFA basic structural formula
  • the modal process can be regarded as a variation of the viscose process.
  • viscose and modal processes shall be referred to collectively as “xanthogenate processes”, as in them polysaccharides are always reacted with CS 2 into the respective xanthogenates.
  • xanthogenate processes for the production of cellulose fibers have generally been known to those skilled in the art for decades.
  • a method for the production of modal fibers is, for example, known from AT 287.905 B.
  • the cellulosic raw material that is primarily used in xanthogenate processes is pulp obtained from wood.
  • the cellulose molecules that exist in wood and also in other plant-based sources of cellulose such as cotton linters, straw, etc. form very long chains, i.e., they exhibit a high degree of polymerization.
  • U.S. Pat. No. 7,000,000 describes fibers obtained by spinning a solution of polysaccharides which substantially consist of repeating hexose units linked via ⁇ (1 ⁇ 3)-glycosidic bonds.
  • These polysaccharides can be produced by bringing an aqueous solution of saccharose into contact with glucosyltransferase (GtfJ), isolated from Streptococcus salivarius (Simpson et al., Microbiology, vol. 41, pp 1451-1460 (1995)).
  • GtfJ glucosyltransferase
  • substantially means that within the polysaccharide chains there may exist occasional defective locations where other bond configurations may occur.
  • these polysaccharides shall be referred to as “ ⁇ (1 ⁇ 3)-glucan”.
  • U.S. Pat. No. 7,000,000 first discloses possibilities for the enzymatic production of ⁇ (1 ⁇ 3)-glucan from monosaccharides.
  • relatively short-chained polysaccharides can be produced without the loss of monomer units, as the polymer chains are built from the monomer units.
  • the production of ⁇ (1 ⁇ 3)-glucan keeps getting less expensive the shorter the polymer chains are, as in that case only a short residence time in the reactors will be required.
  • the ⁇ (1 ⁇ 3)-glucan is to be derivatized, preferably acetylated.
  • the solvent is an organic acid, an organic halogen compound, a fluorinated alcohol, or a mixture of such components. These solvents are costly and complex to regenerate.
  • the object was therefore to provide a polysaccharide fiber as well as a method for the production thereof which does not include the above mentioned problems (e.g., of solubility in an aqueous sodium hydroxide solution).
  • the polysaccharide raw material was to be inexpensive, and the processing method should have already been confirmed as suitable for large-scale use and was to be cost-effective and executable on existing facilities.
  • the above described object is solved by a method for the production of a polysaccharide fiber using a xanthogenate process, wherein the fiber-forming substance is a mixture of cellulose and ⁇ (1 ⁇ 3)-glucan.
  • the ⁇ (1 ⁇ 3)-glucan can be added at various locations of the process in the form of an ⁇ (1 ⁇ 3)-glucan-containing aqueous sodium hydroxide solution.
  • a fiber produced in this way shall also be referred to as viscose or modal fiber even though, in addition to cellulose, it also contains another fiber-forming polysaccharide, namely, said ⁇ (1 ⁇ 3)-glucan.
  • fiber shall comprise both staple fibers having a defined staple length and continuous filaments. All principles of the invention that are described hereinafter generally apply to both staple fibers and continuous filaments.
  • the single fiber titer of the inventive fibers can be between 0.1 and 10 dtex. Preferably, it is between 0.5 and 6.5 dtex, and more preferably between 0.9 and 6.0 dtex.
  • the staple length is usually between 0.5 and 120 mm, preferably between 20 and 70 mm, and more preferably between 35 and 60 mm.
  • the number of individual filaments in the filament yarn is between 50 and 10,000, preferably between 50 and 3,000.
  • the ⁇ (1 ⁇ 3)-glucan can be prepared by bringing an aqueous solution of saccharose into contact with glucosyltransferase (GtfJ) isolated from Streptococcus salivarius (Simpson et al., Microbiology, vol. 41, pp 1451-1460 (1995)).
  • GtfJ glucosyltransferase isolated from Streptococcus salivarius
  • Preferred embodiments of the inventive method are the variants of the viscose process generally known to those skilled in the art as well as of a viscose process modified for the production of modal fibers.
  • At least 90% of the ⁇ (1 ⁇ 3)-glucan are hexose units and at least 50% of the hexose units are linked via ⁇ (1 ⁇ 3)-glycosidic bonds.
  • the method for the production of the inventive fiber consists of the following steps (also see FIG. 1 ):
  • the concentration of the fiber-forming substance in the spinning solution can be between 4 and 15% by weight, preferably it is between 5.5 and 12% by weight.
  • the fiber-forming substance can contain between 1 and 99% by weight of ⁇ (1 ⁇ 3)-glucan.
  • Preferred is a content of the ⁇ (1 ⁇ 3)-glucan between 5 and 45% by weight.
  • Below 5% by weight of ⁇ (1 ⁇ 3)-glucan the economic benefit of the added ⁇ (1 ⁇ 3)-glucan is too low for typical types of use of the inventive fibers; above 45%, competing reactions for the CS 2 in the spinning solution become too intensive, and the spinnability of the solution decreases significantly.
  • the scope of the present invention expressly also includes fibers having an ⁇ (1 ⁇ 3)-glucan content between 1 and 5% by weight and between 45 and 99% by weight, respectively.
  • the remaining part of the fiber-forming substance consists substantially of cellulose.
  • substantially means that low quantities of other substances can be present which primarily originate from the cellulosic raw material, generally from said pulp. Such other substances include primarily hemicellulose and other saccharides, lignin residues, or the like. They are also contained in commercially available viscose and modal fibers.
  • the degree of polymerization of the ⁇ (1 ⁇ 3) glucan employed in the method according to the invention can be between 200 and 2000; values between 500 and 1000 are preferred.
  • a polysaccharide fiber produced by using a xanthogenate process and containing cellulose and ⁇ (1 ⁇ 3)-glucan as fiber-forming substances is also the subject-matter of the present invention.
  • the fiber-forming substance contains between 1 and 99% by weight of ⁇ (1 ⁇ 3)-glucan and more preferably between 5 and 45% by weight of ⁇ (1 ⁇ 3)-glucan.
  • At least 90% of the ⁇ (1 ⁇ 3)-glucan of the inventive polysaccharide fiber are hexose units and at least 50% of the hexose units are linked via ⁇ (1 ⁇ 3)-glycosidic bonds.
  • inventive fibers for the production of various dry-laid and wet-laid papers, nonwovens, hygiene articles such as tampons, panty liners, and diapers, and other nonwovens, especially absorbent nonwoven products, but also of textile products such as yarns, woven fabrics, or knitted fabrics is also the subject-matter of the present invention.
  • the degree of polymerization of the ⁇ (1 ⁇ 3)-glucans was determined by means of GPC in DMAc/LiCl. Subsequently, it is always the weight average of the degree of polymerization (DP W ) that is specified.
  • a viscose xanthogenate containing 29.8% by weight of cellulose, 14.9% by weight of alkali, and 8% by weight of sulfur was reacted in a dissolving unit with a first dissolving liquor containing 4.5% by weight of NaOH and then with a second dissolving liquor containing 9% by weight of ⁇ (1 ⁇ 3)-glucan and 4.5% by weight of NaOH and finally with water.
  • the viscose obtained in this way contains 9% by weight of fiber-forming material, 5.20% by weight of alkali, and 2.4% by weight of sulfur (calculated under the assumption that there are 100% by weight of cellulose as a fiber-forming material), with a ripeness index of 14 Hottenroth and a falling ball viscosity of 80 seconds (determined according to the Zellcheming Leaflet III/5/E).
  • Viscose solutions with 10 and 25% of ⁇ (1 ⁇ 3)-glucan were prepared. These glucan quantities were related to the proportion of the ⁇ (1 ⁇ 3)-glucan in the fiber-forming substance.
  • These viscose types contain 2.2% by weight of sulfur (10% by weight of glucan and 90% by weight of cellulose as fiber-forming materials) and 1.8% by weight of sulfur (25% by weight of glucan and 75% by weight of cellulose as fiber-forming materials), respectively.
  • the solution was extruded into a regeneration bath containing 100 g/l of sulfuric acid, 330 g/l of sodium sulfate, and 15 g/l of zinc sulfate.
  • the spinneret had 1053 perforations with a diameter of 50 ⁇ m. 0.5% by weight of a nitrogen-containing auxiliary agent were added to the viscose spinning solution.
  • stretching by approx. 75% was carried out in the second bath (92° C., 15 g/l of H 2 SO 4 ).
  • the draw-off velocity was 50 m/min.
  • Example 1 In a reference example 1, the viscose from Example 1 was spun into fibers without the addition of the glucan/NaOH solution, but otherwise in the same conditions as in Example 1.
  • the spinneret had 1053 perforations with a diameter of 50 ⁇ m. 0.5% by weight of a nitrogen-containing auxiliary agent were added to the viscose spinning solution.
  • stretching by approx. 75% was carried out in the second bath (92° C., 15 g/l of H 2 SO 4 ).
  • the draw-off velocity was 50 m/min.
  • Example 2 the viscose from Example 2 was spun into fibers without the addition of the glucan/NaOH solution, but otherwise in the same conditions as in Example 2.
  • a modal viscose containing 6.0% by weight of cellulose, 6.20% by weight of alkali, and 1.8% by weight of sulfur, with a gamma value of 65 and a falling ball viscosity of 130 seconds (determined according to the Zellcheming Leaflet III/5/E) was, by means of a spinneret, extruded into a regeneration bath containing 72 g/l of sulfuric acid, 115 g/l of sodium sulfate, and 55 g/l of zinc sulfate.
  • the spinneret had 1053 perforations with a diameter of 45 ⁇ m. 2.5% by weight of a nitrogen-containing auxiliary agent were added to the viscose spinning solution.
  • stretching by approx. 115% was carried out in the second bath (92° C., 15 g/l of H 2 SO 4 ).
  • the draw-off velocity was 50 m/min.
  • Example 3 the viscose from Example 3 was spun into fibers without the addition of the glucan/NaOH solution, but otherwise in the same conditions as in Example 3.
