Definitions

  • the present invention relates to a direct dissolving process for the production of polysaccharide fibers which contain as a fiber-forming substance a (1 - »3) -glucan, with sodium hydroxide solution as a solvent, and the fibers produced therefrom and their use.
  • Polysaccharides play an increasingly important role as materials that can be obtained from renewable raw materials.
  • One of the most abundant polysaccharides is cellulose.
  • Cotton fibers, which consist almost exclusively of cellulose, are an example of the importance of polysaccharides. But also obtained from other cellulosic raw materials such.
  • B. Cellulosic synthetic fibers are becoming increasingly important.
  • viscose fibers and “modal fibers” have been assigned to cellulose fibers by the BISFA (Bureau for the International Standardization of Man-Made Fibers), which are produced by chemical derivatization of cellulose using caustic soda and sulfur (CS2 ) getting produced.
  • BISFA Bostic soda and sulfur
  • modal fiber is a generic term used in the definition of BISFA for a cellulose fiber with a defined high wet strength and high wet modulus (ie the force required to stretch the fiber by 5% when wet) ) stands.
  • lyocell fibers was assigned by BISFA to cellulose fibers made from solutions in an organic solvent without formation of a derivative.
  • the solvent used is a tertiary amine oxide, preferably N-methylmorpholine-N-oxide (NMMO).
  • NMMO N-methylmorpholine-N-oxide
  • Tertiary amine oxides have long been known as alternative solvents for cellulose. From US Pat. No. 2,179,181 it is known, for example, that tertiary amine oxides are able to dissolve pulp without derivatization and that from these solutions cellulosic shaped bodies such as e.g. Fibers can be made.
  • US 3,447,939 cyclic amine oxides as
  • EP 356 419 B1 describes the preparation of solutions and EP 584 318 B1 describes the spinning of such solutions of cellulose in
  • the lyocell process is much safer than the viscose process, but due to the economic necessity of almost complete cycle closure, it has procedural disadvantages, since substances can accumulate in the circuits.
  • Monomerbausteinen be prepared, since the polymer chains are composed of the monomer units. In contrast to the production of short-chain cellulose molecules, the shorter the polymer chains, the cheaper the production of a (1-3) -glucan, since then only a short residence time is necessary in the reactors.
  • the cx (1 ⁇ 3) -glucan is to be derivatized, preferably acetylated.
  • the solvent is preferably an organic acid, an organic halogen compound, a fluorinated alcohol or a
  • the object of this prior art therefore was to provide an alternative direct dissolving process for the production of polysaccharide fibers, which manages without the CS2 necessary in the viscose process and without the complicated circuit closure of a lyocell process.
  • Direct dissolving process for producing a polysaccharide fiber whose fiber-forming substance is a (1-3) glucan, the direct dissolving process being based on caustic soda.
  • the present invention therefore relates, on the one hand, to a process for producing a polysaccharide fiber whose fiber-forming substance is cx (1 ⁇ 3) -glucan, the process being a direct dissolving process and the solvent being sodium hydroxide solution.
  • Salt contents and a very low acid concentration whereby the spun yarn is initially only coagulated and regenerated only in the second acid regeneration.
  • the H2S04 concentration in the spinning bath is between 200 and 500 g / l. In a second preferred embodiment of the method according to the invention, therefore, the H2S04 concentration in the spinning bath is between 20 and 60 g / l.
  • the spun fiber is subsequently drawn in an acidic regeneration bath.
  • the NaOH concentration in the spinning solution should be between 4.0 and 5.5% by weight, based on the total amount of the spinning solution. Outside this range, the solubility of glucan is insufficient.
  • fiber is intended to include both staple fibers of defined cut length and continuous filaments All of the principles of the invention described below apply in principle to both staple fibers and continuous filaments.
  • the individual fiber titer of the fibers according to the invention can be between 0, 1 and 10 dtex. It is preferably between 0.5 and 6.5 dtex and more preferably between 0.9 and 6.0 dtex.
  • the cut length is usually between 0.5 and 120 mm, preferably between 20 and 70 mm and particularly 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 oc (1-3) glucan can be prepared by contacting an aqueous solution of sucrose with glucosyltransferase (GtfJ) isolated from Streptococcus salivarius (Simpson et al., Microbiology, vol 41, pp 1451-1460 (1995) )).
  • GtfJ glucosyltransferase isolated from Streptococcus salivarius
  • At least 90% of the a (1 ⁇ 3) -glucan consists of hexose units and at least 50% of the hexose units are linked by cx (1 ⁇ 3) -glycosidic bonds.
  • the process for producing the fiber according to the invention consists of the following steps:
  • the concentration of the fiber-forming substance in the spinning solution may be between 4 and 18 wt .-%, preferably 4.5 to 12 wt .-%.
  • the degree of polymerization of the cx (1-3) glucan used in the process according to the invention expressed as weight average DP W , can be between 200 and 2000; preferred are values between 500 and 1000.
  • the cx (1-> 3) -glucan of the polysaccharide fiber of the invention consists of at least 90% hexose units and at least 50% of the hexose units are linked by a (1-3) -glycosidic bonds.
  • polysaccharide fiber whose fiber-forming substance is a (1-3) -glucan and which has been prepared by the direct dissolution process also described above in sodium hydroxide solution.
  • the present invention is the use of the fibers according to the invention for the production of textile products such as yarns, woven fabrics, knitted or knitted fabrics as well as of
  • Sanitary articles such as tampons, panty liners and diapers and other nonwovens, in particular absorbent nonwovens products.
  • the invention will be described by way of examples. However, the invention is expressly not limited to these examples, but includes all other embodiments based on the same inventive concept.
  • the degree of polymerization of the oc (1- »3) -glucans was determined by GPC in
  • aqueous glucan solution containing 9% a (1-3) glucan with a DP W of 800 and 4.5% by weight NaOH was cooled to 3 ° C, filtered and deaerated.
