Definitions
- the invention relates to a method for producing cellulosic multicomponent fibers with reduced swelling capacity and increased wet abrasion resistance.
- Viscose fibers can undergo a considerable increase in the swelling capacity, expressed by the water retention capacity (WRV), by incorporation of secondary components (M. Einmann et al., Lenzinger Berichte 84 (2005) 42-49). Examples of a decrease in WRV are unknown.
- WRV water retention capacity
- N-methylmorpholine N-oxide monohydrate makes it possible to produce lyocell fibers with discrete incorporation of the second component in the pore system, which have an increased swelling capacity, irrespective of whether the secondary component has hydrophilic or hydrophobic properties
- WO 98/09009 claims the addition of linear synthetic polymers, for example, low density polyethylene, to cellulose NMMO solutions. Also in this case, although the added polymers are hydrophobic and liquid when dispersed (working temperatures above the melting temperature of the additional polymers), the formation of a matrix / island structure with a constant or increased swelling capacity takes place. Investigations on Lyocell fibers or modified Lyocell fibers have shown that there is a double logarithmic relationship between their WRV and wet scrub resistance (NSB). (Ch Michels, Final Report on the BMWA Project "Model Studies on the Lyocell Process", Reg. No. 1077/03 (2005) 21). Only by subsequent derivatization of a cellulose fiber with hydrophobic substituents can be achieved a reduction in swelling capacity and an increase in NSB.
- NBS wet scrub resistance
- a process for producing lyocell fibers from ionic liquids is claimed in DE 10 2004 031 025 B3, wherein these cellulose fibers have a comparable swelling capacity as Lyocell fibers produced by the NMMO process.
- WO 2005/098546 A2 describes the preparation of mixtures of at least two different polymers or copolymers in at least one ionic liquid. The polymers are individually dissolved directly in the nearly anhydrous ionic liquids, the polymer solutions mixed and cast films obtained from the polymer blend by precipitation with aqueous media and characterized. A production of fibers is not described, and there are no statements on the swelling capacity of the resulting polymer blends.
- the object of the present invention is to provide a simple process for producing cellulosic multicomponent fibers with reduced swelling capacity and increased wet scrub resistance.
- this object is achieved by dispersing 75-25% by volume of cellulose and 25-75% by volume of at least one further fiber-forming polymer component in a water-containing ionic liquid with the addition of stabilizers, removing the water as far as possible under shear, heat and vacuum.
- the resulting microscopically homogeneous solution is deformed by at least one spinneret to the fiber / fiber bundle, passing through an air-conditioned gap, the solution solution jets by treatment with a tempered solution which is miscible with the ionic liquid, for the cellulose and the other fiber-forming polymer component but represents a precipitant precipitates under spinodal segregation, separates from the precipitation bath and then post-treated.
- pulps of wood, cotton and other annual plants prepared by the sulfite, sulfate or prehydrolysulfate method have been found to be suitable.
- the bleaching process of the pulps is of secondary importance.
- secondary polymers polyacrylonitrile (PAN) and polyacrylonitrile copolymers, for example with 6% by weight of methyl acrylate, have proven to be optimal.
- the second component powder or fiber form Dolanit ®, ® Dolan, Dralon ®, Orion ®, Wolpryla- fiber, etc.

- the stabilization of the polymer solutions was carried out by adjusting their hydrogen ion concentration (pH) with a nonvolatile base, for example sodium hydroxide or polyethyleneimine and, if appropriate, adding propylgal latent or similar stabilizers, such as tannins, p-phenylenediamine, quinone.
- a nonvolatile base for example sodium hydroxide or polyethyleneimine
- propylgal latent or similar stabilizers such as tannins, p-phenylenediamine, quinone.
- Suitable precipitation media are water and / or water-miscible alcohols, which may contain up to 50% of the ionic liquids used as solvents.
- the preparation of cellulose secondary polymer solutions in ionic liquids and their characterization and spinning into fibers was carried out according to the following general procedure:

- the secondary polymer When the secondary polymer was in powder form, the cellulose alone was beaten in water and squeezed. The pulverulent secondary polymer was dispersed directly in the ionic liquid containing 30% by mass of water and stabilizers, then the cellulose which had been pressed moist was introduced and dispersed, and the aqueous suspension was admixed by adding a 0.1 molar aqueous NaOH solution pH adjusted to> 8.
