Definitions
- the invention relates to a method for the treatment of cellulosic shaped articles according to the preamble of claim 1.
- NMMO N-Methylmorpholine-N-oxide
- EP-A 0 553 070 Processes for producing cellulosic molded articles from a solution of cellulose in a mixture of NMMO and water are e.g. in U.S. Patent 4,246,221 or PCT-WO 93/19230. The cellulose is precipitated from the solution in an aqueous precipitation bath. Fibers produced in this way are characterized by a high fiber strength in the conditioned and in the wet state, a high wet modulus and a high loop strength.
- a special property of these fibers is their high tendency to fibrillation, especially under stress when wet, e.g. during a washing process. While this property is desirable for certain applications of the fibers and gives interesting effects, the usability for other purposes, e.g. Textiles that are said to be wash-resistant are reduced.
- the fibers which can be freshly spun or have already been dried, are treated in an alkaline medium with an aqueous system which contains a chemical reagent with 2 to 6 functional groups which can react with cellulose.
- a chemical reagent with 2 to 6 functional groups which can react with cellulose.
- cyanuric chloride in particular substituted dichlorotriazines, are also mentioned as suitable substances in EP-A-0 538 977.
- addition products of cyanuric chloride with poly (ethylene glycol) monomethyl ether are used.
- This object is achieved by a method according to the preamble of claim 1, which is characterized in that a compound of the formula as a textile auxiliary
- Chlorine is particularly preferred as the halogen radical X.
- the textile auxiliaries used according to the invention which are relatively inexpensive to obtain, bring about an improvement in the properties of the shaped bodies which is just as great or even greater than that e.g. substances known from EP-A 0 538 977 which are difficult to produce. It is thus possible to economically e.g. to solve the problem of the fibrillation tendency of solvent-spun fibers.
- the compounds according to the invention are present in the aqueous solution in an alkaline medium in ionic form.
- the sodium, potassium or lithium salt is preferably used as the metal salt.
- the radicals R are preferably anionic radicals, for example, -S0 3 " or -C, -C 6 alkyl-S0 3 " or C0 2 " or -C, -C 6 alkyl-C0 2 " .
- the radicals R can also be cationic.
- R are preferred with, for example
- the treated cellulosic shaped bodies are never dried fibers. Solvent-spun fibers in the state before the first drying are referred to as “never dried” fibers. It has been shown that the use of compounds of the formula (I), in particular on fibers that have never been dried, results in a substantial reduction in the tendency to fibrillation.
- the pH of the aqueous solution of the textile auxiliary is preferably 12 to 14 when it is brought into contact with the moldings.
- the shaped bodies are preferably subjected to a heat treatment during or after being brought into contact with the aqueous solution of the textile auxiliary.
- the heat treatment can take place during and / or after contact with the weakly alkaline solution of the textile auxiliary, but also after the pressed molded articles have been brought into contact with the more alkaline aqueous solution. Satisfactory results are also achieved if heat treatment only takes place after the shaped bodies have been brought into contact with the more alkaline aqueous solution.
- the stepwise reaction of the two reactive groups of the textile auxiliary can thus be controlled in a targeted manner by the respective use of the heat treatment.
- the invention also relates to the use of a compound of the formula
- X represents halogen
- R H or an ionic radical
- n 0 or 1, or a salt of this compound for reducing the fibrillation tendency of solvent-spun cellulosic fibers.
- UV absorbers e.g. textile finishing 31 (1996) 11/12. 227-234.
- UV absorbers reduce the reflectance or transmission of UV radiation through the textile.
- the UV absorbers must be carefully selected depending on the fiber material. It has now been shown that the compounds of the formula (I) act as excellent UV absorbers when used on solvent-spun fibers or textile fabrics.
- the invention therefore also relates to the use of a compound of the formula
- the friction of the fibers against one another during washing processes or when finishing processes in the wet state is simulated by the following test: 8 fibers are added to a 20 ml sample vial with 4 ml water and for 3 hours in a laboratory shaker type RO-10 from Gerhardt, Bonn (FRG) shaken at level 12. The fibrillation behavior of the fibers is then assessed under the microscope by counting the number of fibrils per 0.276 mm fiber length and is given a fibrillation value from 0 (no fibrils) to 6 (strong fibrillation).
- Twenty 40 mm long fibers are placed over a 1 cm thick metal roller and weighted with a pretension weight depending on the titer of the fibers.
- the roller is covered with a viscose filament yarn stocking and is continuously moistened.
- the roller is rotated at a speed of 500 revolutions / minute and at the same time moved back and forth transversely to the fiber axis, whereby a pendulum movement of approx. 1 cm is carried out.
- Example 1 The number of revolutions is measured until the fibers are worn through. The average value of the abrasion cycles of the 20 fibers is taken as the measured value. The higher the number of revolutions until the fibers are worn through, the better the fibrillation behavior of the fibers.
- Example 1 The higher the number of revolutions until the fibers are worn through, the better the fibrillation behavior of the fibers.
- a colored knitted fabric made of solvent-spun fibers was mixed in a liquor ratio of 1:30 with an aqueous solution containing 20 g / 1 sodium salt of 2,4-dichloro-6-hydroxy 1,3.5-triazine, 20 g / 1 NaOH and 1 g / 1 Leonil SR (wetting agent, manufacturer: Hoechst) brought into contact.
- the solution had a pH of 13.
- the knitted fabric was impregnated with the solution for 5 minutes, the excess solution was pressed off with a pad at 1 bar and heat-treated with steam at 100 ° C. for 5 minutes. The knitted fabric was then washed repeatedly with 2% acetic acid and water and finally dried.
- An undyed knitted fabric made of solvent-spun fibers was treated as described in Example 1 and subjected to a wet scrub test.
- the mean value from the tests was 620 revolutions.
- the fibers After shaking for 3 hours, the fibers had an average of 9 fibrils per 0.276 mm and a fibrillation value of 2.75. In contrast, fibers not treated with the textile auxiliary had an average of 12 fibrils per 0.276 mm and a fibrillation value of 4 after shaking for 3 hours. After 9 hours of shaking in the test device, an analogous behavior was shown. In the abrasion test, the treated fibers had an average of 125 revolutions, while untreated fibers had an average of 13 revolutions.
- the reflectance of UV radiation was measured on solvent-spun fibers treated according to Example 3 or Example 4. In all cases there was a significant reduction in the reflectance value compared to untreated, solvent-spun fibers. The order of magnitude of the part of UV radiation that is no longer remitted and therefore absorbed is approximately 40%.
