Definitions
- the present invention provides flame-retarded cellulosic regenerated fibers having improved functional properties for textile
- Fibers by the viscose process are mainly known today as cellulosic regenerated fibers and are produced worldwide for standard applications in the textile and nonwovens sector with a single fiber titer of between 0.8 and 16 dtex.
- flame-retardant finish of viscose fibers various chemicals are described in the literature. Above all, flame retardants based on halogens, silicon and phosphorus are used.
- the patent US2678330 describes the use of a bis (2,3-dichloropropyl) chlorophosphonate for this purpose.
- the publication GB1158231 mentions the use of a tris (1-bromo-3-chloro-2-propyl) phosphate.
- the patent FR2138400 describes the use of liquid polybromobenzenes and more preferably hexabromobenzene. Since liquid flame retardants are only embedded in the structure of the fiber but do not bind to the cellulose component, the migration of these chemicals from the fiber is significantly higher than with solid substances. Especially after repeated drying at high temperatures (e.g., in the tunnel dryer), the flame retardancy of the fiber can be significantly reduced.
- the Soviet patent SU661047 also describes the use of halogenated compounds such as hexachlorocyclohexane, halogenated benzenes and tris (dibromo-propyl) phosphate.
- halogenated flame retardants was in recent years due to ecological Concerns greatly reduced and does not represent a sustainable solution for future developments.
- Tris (dibromo-propyl) phosphate for example, even led by the Oeko-Tex® community as a prohibited flame retardant.
- Viscose fibers whose flame retardant effect relies on the use of silicates - described e.g. in the patents W09313249 or CN1847476 - are ecologically harmless, but by no means meet the

- Viscose fibers using flame retardant dispersions based on a 2,2'-oxybis [5,5-dimethyl-1, 3,2-dioxaphosphorinan] 2,2'disulfide There is described as an important feature of the invention that the particle size may be a maximum of 10 pm and that the spinning mass must therefore be cleaned before spinning through filters with a maximum mesh size of 10 pm. However, it has been found that this criterion is not sufficient to produce fibers that describe the one described here
- Particle size of 10 pm may be for viscose filaments, i. H.
- Endless filaments sufficient, but far from meeting the requirements of modern staple fiber production with fiber finenesses of about 1 to 4 dtex; a 1, 3 dtex fiber has a diameter of about 10 pm.
- Standard viscose fibers are now widely used in light-weight fashion textiles.
- the low strength, especially when wet, the high elongation and the high surface shrinkage put the use of viscose but limits.
- these textile properties do not permit use in segments which require frequent washing (especially in industrial washes) of the textiles.
- a measure of the washability is the area shrinkage.
- BISFA wet modulus measured according to the regulations of BISFA and therefore hereafter called BISFA wet modulus (BISFA, Testing Methods Viscose, Modal, Lyocell and Acetate Staple Fibers and Tows, 2004 Edition).
- the fibers described in the prior art, or commercially available are all made by standard viscose methods. Although they show comparatively good mechanical fiber data for flame-retardant viscose fibers, since the phosphorus contents are very low.
- Synthetic high performance fibers such as (aromatic) polyamides, aramids, polyimides and the like are already commonly used for such products.
- these fibers have a low wearing comfort, since they are not able to absorb moisture sufficiently.
- the prior art merely discloses

- the fiber according to the invention contains at least 2.8%, preferably between 3.2% and 6.0%, particularly preferably between 3.5% and 6.0% phosphorus, in each case based on cellulose.
- a flame-retarded fiber of the invention having a BISFA wet modulus B m of greater than or equal to 0.5 x (V " T) x 10 ⁇ at an elongation of 5% in the wet state, where T is the denier of a single fiber , expressed in dtex, B m is expressed in cN / tex.
- the fiber according to the invention is present as a staple fiber, d. H. it becomes uniform throughout the manufacturing process
- Usual cutting lengths for staple fibers for the textile sector are between about 20 and 150 mm. Only such a uniform length of all Fibers allow easy processing on today's in the textile chain usual machines with high productivity.
- the present invention also provides the use of the fiber according to the invention for the production of a game.
- a yarn is characterized by yarns made of fibers, which were previously available, by a significantly higher strength. Order for the respective
- such yarn according to the invention in addition to the fibers according to the invention may also contain fibers of other origin, for example wool, flame-retardant wool, para- and meta-aramids, polybenzimidazole (PBI), p-phenyl-2,6-Bezobisoxazol (PBO ), Polyimide (P84®), polyamideimide (Kermel®), modacrylic, polyamides, flame-retarded polyamides, flame-retarded acrylic fibers, melamine fibers, polyesters, flame-retardant polyesters, polyphenylene sulfide (PPS), polytetrafluoroethylene (PTFE), glass fibers, cotton, silk,

- this fabric may also contain other fibers, for example and in particular wool,
- PPS Polyphenylene sulfide
- PTFE polytetrafluoroethylene
- PANOX® fibers Polyacrylonitrile (PANOX®) fibers and electrically conductive fibers, and mixtures of these fibers.
- the sheet is preferably a woven, knitted or knitted fabric, but may in principle also be a nonwoven. Also for high quality nonwovens is the use of fibers with high BISFA wet modulus and high strength crucial.
- the mixture of the fibers according to the invention with the other fibers is either by mixing before yarn production, the so-called
- the fiber according to the invention can be replaced by an inventive
- Endless filaments have been known in principle for many years and, for example, described in detail by K. Götze, Chemiefasern nach den Viskoseclar, 1967.
- the textile properties of the resulting fibers and filaments are significantly affected by many parameters.
- limits are set for many influencing factors by the design of the existing production plants, which can not be exceeded for technical or economic reasons, so that any variations of the parameters are often not possible and therefore the expert would not have caused this.
- the spinning parameters must be adjusted accordingly due to the Zudöstechnik the flame-retardant FR-pigment.
- the invention therefore also provides a process for producing a flame retarded regenerated cellulose fiber for textile applications by spinning a viscose with a content of 4 to 7% cellulose, 5 to 10% NaOH, 36 to 42% (based on cellulose) carbon disulfide and 1 to 5% (based on cellulose) of a modifier in a spin bath, stripping off the coagulated filaments, using a viscose whose spin gamma value is 50 to 68, preferably 55 to 58, and whose Spinning viscosity is 50 to 120 falling seconds; and that the

- a pigmented organophosphorus compound is spun in the form of a pigment dispersion.
- a viscose is used, to which the modifier is added only shortly before the spinning of the viscose.
- Cellulosic molecules bound carbon disulfide molecules.
- Spinning gamma value is determined according to Zellcheming leaflet draft by R. Stahn [1958] or leaflet III / F 2.
- the term "falling ball” is understood to mean the viscosity determined by the falling ball method; it is expressed in terms of bullet seconds. The determination is given in K. Götze, Chemiefasern [1951], p. 175.
