Definitions

  • the invention relates to a method for producing cellulose fibers with a reduced tendency to fibrillation.
  • a tertiary amine oxide in particular N-methylmorpholine-N-oxide (NMMO)
  • NMMO N-methylmorpholine-N-oxide
  • Fibrillation is understood to mean breaking open the wet fiber in the longitudinal direction under mechanical stress in the wet state, as a result of which the fiber is given a hairy, furry appearance.
  • One made from these fibers and dyed fabric loses color intensity over the course of a few washes.
  • the reason for the fibrillation is assumed to be that the fiber consists of fibrils arranged in the direction of the fibers, between which there is only a small amount of crosslinking.
  • WO 92/14871 describes a method for producing a fiber with a reduced tendency to fibrillation. This is achieved in that all baths with which the freshly spun fiber comes into contact before the first drying have a pH of a maximum of 8.5.
  • WO 92/07124 also describes a method for producing a fiber with a reduced tendency to fibrillation, according to which the freshly spun, that is to say not yet dried, fiber is treated with a cationic polymer.
  • a polymer with imidazole and azetidine groups is mentioned as such a polymer.
  • treatment with an emulsifiable polymer e.g. Polyethylene or polyvinyl acetate, or crosslinking with glyoxal.
  • the object of the invention is to provide a method which can be carried out in a simple manner and which allows cellulose fibers of the Lyocell genus to be produced with a reduced tendency to fibrillation.
  • the process according to the invention for the production of cellulose fibers with reduced tendency to fibrillation consists in that the freshly spun, not yet dried fibers are brought into contact with a textile auxiliary which carries at least two reactive groups and are washed with an aqueous buffer, with the proviso that as Auxiliary textile Glyoxal is not used.
  • Dyes which have two reactive groups have proven particularly useful as textile auxiliaries.
  • textile auxiliaries which are colorless, i.e. do not absorb visible light.
  • Textile auxiliaries which carry one or two vinylsulfone groups as reactive groups are preferably used according to the invention.
  • An expedient embodiment of the method according to the invention is characterized in that the freshly spun fibers are brought into contact with the textile auxiliary in an alkaline environment.
  • Another preferred variant of the method according to the invention is that the fibers brought into contact with the textile auxiliary are heat-treated.
  • the heat treatment drastically shortens the impregnation time.
  • EP-A-0 538 977 published on April 28, 1993, describes a heat treatment of cellulose fibers impregnated with a dye.
  • heating the fibers impregnated with the textile auxiliary with hot air can shorten the impregnation time, but there is a risk that the fibers will be heated irregularly.
  • the outer fibers of a fiber bundle to be dried may already have partially dried, while the fibers inside have not yet reached the required temperature. This has an adverse effect on the quality of the fibers produced. It has been found that this disadvantage, which occurs in simple heat treatment, can be overcome if the fibers are irradiated with electromagnetic waves, in particular with microwaves.
  • the fibers When irradiated with microwaves, the fibers are heated uniformly on the one hand, and on the other hand premature drying of the fibers can be prevented, since irradiation with electromagnetic waves offers the possibility of, for example, welding the fiber bundle into a plastic covering and exposing it to the electromagnetic field in the welded state .
  • the invention further relates to a process for the production of cellulose fibers with reduced tendency to fibrillation, in which process a solution of cellulose in a tertiary amine oxide is spun into fibers and the freshly spun fibers are brought into contact with a textile auxiliary which carries at least two reactive groups and are heat-treated, which method is characterized in that the heat treatment is carried out by irradiation with electromagnetic waves.
  • a textile auxiliary is preferably used which carries vinyl sulfone groups as reactive groups and is preferably a dye.
  • textile auxiliaries can also be used are used that are colorless, i.e. do not absorb visible light.
  • Another preferred embodiment of the method according to the invention is that the heat treatment is carried out by means of microwaves.
  • the friction of the fibers against one another during washing processes or during finishing processes when wet was simulated by the following test: 8 fibers with a length of 20 mm were placed in a 20 ml sample vial with 4 ml of water and were held in a laboratory shaker of the type RO for 9 hours. 10 from Gerhardt, Bonn (FRG) shaken at level 12. The fibrillation behavior of the fibers was then assessed under the microscope by counting the number of fibrils per 0.276 mm fiber length.
  • Fiber strength and fiber elongation were tested according to the BISFA regulation "Internationally agreed methods for testing viscose, modal, cupro, lyocell, acetate and triacetate staple fibers and tows", edition 1993.
  • Fibers were treated with the dye Remazol Black B and Remazol Red RB as textile auxiliaries (manufacturer: Hoechst AG) in accordance with the process described above.
  • the dye Remazol Black B carries two vinyl sulfone groups and the dye Remazol Red B carries a vinyl sulfone group and a monochlorotriazine group.
  • the fleet contained 3% Remazol Black B and 0.5% Remazol Red RB.
  • the pH of the liquor was 4.6 in each example.
  • the aqueous buffer used was an aqueous solution containing 3% acetic acid and 7% sodium acetate. The pH of this solution was 4.6. After the treatment with the buffer, the fibers were washed with water for 15 minutes and then examined.
  • Table la shows the fixing agent used in each case, the fibrillation (number of fibrils), the titer (dtex), the fiber strength (cN / tex) and the fiber elongation (%).
  • Examples 1, 2 and 3 were carried out with the dye Remazol Black B and Example 4 with the dye Remazol Red RB.
  • Table 1b shows the results of comparative tests which were carried out without dye.
  • Remazol Black B and Remazol Red RB are therefore representative of other textile auxiliaries that also carry at least two reactive groups.
  • Table 2 shows that heat treatment of the fibers impregnated with the textile auxiliary agent drastically reduces the impregnation time and that the tendency to fibrillation is nevertheless reduced.

Abstract

L'invention concerne un procédé de fabrication de fibres de cellulose présentant une tendance réduite à la fibrillation, selon lequel la cellulose en solution dans un oxyde d'amine tertiaire est filée en vue de former des fibres. Les fibres venant d'être filées sont mises en contact avec un adjuvant textile qui comprend au moins deux groupes réactifs, puis sont soumises à un traitement thermique. Ce procédé se caractérise en ce que le traitement thermique s'opère par irradiation avec des ondes électromagnétiques.
