Definitions
- the present invention relates to a cellulosic fiber of the Lyocell genus.
- Fibers of the Lyocell genus are produced by a solvent spinning process in which the cellulose is dissolved in an organic solvent directly without the formation of a derivative and the solution is spun. Such fibers also have the name "solvent-spun” fibers.
- "Lyocell” is the generic name given by BISFA (The International Bureau for the Standardization of man-made fibers) for cellulose fibers which are produced by producing cellulose in an organic form without the formation of a derivative Solvent is dissolved and fibers are extruded from this solution using a dry-wet spinning process or a melt-blown process.
- An organic solvent is understood to mean a mixture of an organic chemical and water. As an organic solvent, N-methyl-morpholine-N-oxide is used on a commercial scale today.
- the solution of the cellulose is usually extruded using a molding tool and shaped in the process.
- the formed solution passes through an air gap into a precipitation bath, where the shaped body is obtained by the solution precipitating.
- the molded body is washed and, if necessary, dried after further treatment steps.
- a method for producing Lyocell fibers is e.g. in US-A 4,246,221. Lyocell fibers are characterized by high strength, high wet modulus and high loop strength.
- EP 0 494 851 describes a process for the production of lyocell fibers in which the distortion (the ratio of the thread take-off speed divided by the nozzle hole exit speed) is at most 1 or in particular less than 1.
- Conventional fibers of the Lyocell genus have a ratio V of the strength of the fiber in the conditioned state FFk to the fiber elongation in the conditioned state Fdk (measured and calculated according to the methods described in more detail below) of well over 2.2.
- the present invention relates to a fiber of the Lyocell type, which is characterized in that the ratio V of the strength of the fiber in the conditioned state FFk to the fiber elongation in the conditioned state Fdk is 2.2 or less.
- the ratio V is preferably 2.0 or less, particularly preferably 1.8 or less.
- the ratio V should more preferably not be less than 1.
- the fiber according to the invention preferably has a titer of 6 dtex to 25 dtex.
- the titer of the fiber depends in particular on the take-off speed or on the ratio of the take-off speed to the speed at which the spinning solution emerges from the spinneret.
- the fiber according to the invention is preferably in the form of a staple fiber.
- Fibers according to the invention are preferably produced using a method in which the distortion assumes a value of greater than 1. It has been found that the fiber according to the invention is particularly suitable for use in carpets, textile floor coverings, wall coverings and / or decorative materials, in particular at a higher titer of 12 dtex, 15 dtex or more.
- the carpets on the market today are largely made of synthetic fibers polyamide and polypropylene, and of wool. Mixtures of wool with polyamide and polypropylene are also used. Fibers such as polyacrylonitrile, polyester and cotton play a subordinate role.
- viscose fibers with a higher titer e.g. 17 dtex
- the viscose fiber was completely eliminated from this area.
- carpets are used because of the higher living comfort. For areas with less stress, velor carpets according to the tufting method are mostly used. For areas with higher mechanical stress, sling or felt carpets are used.
- tufted carpets with excellent mechanical properties can be produced from lyocell fibers with a higher titer of, for example, 15 dtex, especially in combination with synthetic fibers.
- Carpets made from lyocell fibers have an inherently antistatic behavior compared to carpets made from synthetic fibers and / or wool.
- the voltage in the standardized walk tests mentioned is in the range of less than 1 kV.
- lyocell fibers are not affected by moths and therefore do not need to be additionally equipped. Lyocell fibers can be dyed using the techniques known per se for cellulose fibers and therefore enable a wide range of color variations.
- lyocel fibers with a higher titer and a balanced ratio V lies in the higher bending stiffness compared to other cellulose fibers such as e.g. Viscose.
- the fiber strength in the conditioned state FFk (cN / tex) and the fiber elongation in the conditioned state FDk (%) were determined in each case from the fibers obtained in accordance with the "Testing methods viscose, modal, lyocell and acetate staple fibers and tows" published by BISFA.
- the ratio V was determined from the values thus determined for FFk and FDk by dividing FFk (cN / tex) by FDk (%).
- FIG. 2 This is illustrated in FIG. 2, in which the absolute fiber strength “FFk absolute” (FFk times the respective fiber titer) and the fiber elongation FDk are plotted against the fiber titer. While the absolute fiber strength increases linearly with increasing titer, the fiber elongation initially increases with increasing titer to rise again with higher titles.
- Table 2 illustrates the high bending stiffness of fibers of the Lyocell type compared to viscose fibers.
- the bending stiffness is determined using a method developed by the applicant.
- the measured value is specified as the titer-related ratio of the gradient from force to displacement over a linear measuring range.
- a conditioned fiber is clamped horizontally in a clamping beam and cut to a length of exactly 5 mm using a device.
- the clamping bar is moved upwards at a constant speed via an electric drive.
- the fiber is pressed against a sensor plate, which is adapted to a force transducer. The stiffer a fiber is, the higher the measured force.
