Abstract
The present invention relates to an aminated cellulose fiber which is obtained by adding one or more starches etherified with C2-C5 alkylamines which may be further substituted in the alkyl portion by 1 or 2 additional hydroxyl and methoxy groups and whose primary amino or ammonium group, or secondary, tertiary or quaternary substituted with C1-C4 alkyl and having a degree of substitution of between 0.1 and 3 to a paste of viscose, an alklicellulose or a cellulose solution and spinning the fiber from the same
Description
CELLULOSE FILLING REGENERATION CQN HIGHLY REPLACED PIPELINES AND USE OF MODIFIED FIBRO
DESCRIPTIVE MEMORY
The viscose fiber has essentially the same coloring characteristics as the cotton fiber, which is usually used, the dyeing of the natural or regenerated cellulose material requires the presence of lcali donating agents and also elec-t rol t-t so that satisfactory results can be obtained from fixation with reactive agents. However, the necessary additions are precisely those that are ecologically unacceptable. The future is thus increasingly linked to the regenerated cellulose fiber which first converts, without further process steps, to modifications which have a high affinity for dyeing, that is to say modifications that are dyeable without salt and alkali. Fiber modified in this manner resembles animal fiber, such as wool or silk, in its chemical behavior and can be dyed in neutral conditions with ammonic dyes without further additions of salt or alkali. A special field of application in this regard are the mixing fabrics, for example the fabrics composed of mixtures between polyurethane and modified viscose, which can then be dyed in a single bath. Viscose modifications have already been described in the literature. DE-fi-1 948 487 describes a process for producing viscose fiber having novel dyeing properties. It produces the fiber using polyarms, which not only severely alter the original character of the fiber but also are responsible for the unsatisfactory level of irishness of the subsequent dyeing. Simiiarrnent or, DE-fl-1 469 06? it refers to "armnalized fiber". The additions are arninoe-tiL- and diet laminoetii-cellulose in high concentrations and the dyeing is done exclusively with acid dyes. The disadvantage of this procedure is that the additions must first be synthesized and isolated in a complicated manner and, what is more, they are expensive. It is an object of the present invention to produce a viscose fiber that has significantly more affinity with the reactive as well as direct dyes and which differs absolutely from the normal fiber also in desired performance characteristics. This object is surprisingly achieved by mixing it with a paste of viscose, cellulose or alcalicellulose solution, highly substituted starch derivatives, ammonia containing compounds and the subsequent spinning. The present invention provides as aforesaid animated regenerated cellulose fiber which is obtained by adding one or more etherified starches with C2-C5alkylolamines which can be further substituted in the alkyl portion by one or two more hydroxyl and oxoxy groups and whose amino group is it a primary or secondary ammonium, or secondary, tertiary or quat ornario group substituted with Ci -O4 alkyl or with -0- (Cl I2)? -SO2- ÍOH2) and -NR or -0- (CH2)? -S? 2- (CH2) and -NR3 + ñ ", e where x and y are each 2 <3, the radicals R are identical or different and each is hydrogen, methyl or ethyl, and ft is an anion , and having a degree of substitution of between 3.1 and 3, preferably from 0.11 to 2, on a par from 0.2 to 1, in a concentration of 1 to 20% by weight, calculated as dry weight and based on the content of pulp cellulose, a viscose raisin, an alkali cellulose to a cellulose soludon and spinning the fiber therefrom.Etherified starch derivatives have a degree of substitution of 3.1 and 3. A degree of substitution of 3 means that each of the 3 free OH groups is etherified in each glucose unit A degree of substitution of 0.1 means that on average, each tenth glucose unit has an etherified OH group. degree of substitution of approximately 0.05 (Houben-Ueyi, 1987, Vol. E 20, part 3, pages 2135-2151), but no starches having a degree of substitution of (1.1 or higher. The present invention therefore also provides derivatives of the above-described alkylamino-modified starches having a degree of substitution between (1.1 and 3)., preferably from ü. 2, with the exception of a starch with a phylohydroxypropyl group, preference is given for the purpose of the present invention to those starch ethers whose ether group has the formula 0- (CH2) x -NR2, -0-CH2 -OHOH-CH -NR2, -0- (0H2) M -S02 - (0H2) and * MR2, -0- (CH2) "- 02-Í0H2) and -MR + 3H-, -0- (CH2) x - + NR3- or -0-OH2 CHOH -CH2 -NR + 3I1", where x and y are each 2 or 3, the radicals R are identical or different and each denote hydrogen, methyl or ethyl, and 0 is an anion, preferably chloride or sulfate, Particular preference is given to those starch ethers whose ether group has the formula -O-CH2-CH2-MH2, -0 -CH2 -CHOH-CH2 -N + (CH3) 3 or -O-CH2CH2 ~ N + (CH3) 3 - The novel starch ethers having said high degree of substitution form fluid to highly viscous materials in water ranging in viscosity of 1 at 30 Pas (approximately 20% strength by weight of aqueous solution, which, in the production of The regenerated cellulose fiber can be added to the spinning pulp, cellulose or alkalellulose solution without further processing. The degree of polymerization of the starch ethers of this invention is advantageously between 100 and 1000, preferably between 100 and 400, anhydroglucose units. If the degree of polymerization was less than 100, the starch ether could be extracted by washing the fiber after spinning. The starch ethers of this invention are prepared by reacting any desired starch, for example potato starch, corn starch or wheat starch, with an allyl of C 5 having a subst 11 reactive towards the OH groups, for example, substitution with or-e-chloro-fi-hydrox, 1,2-epox ?, L- (sulfa oetj isulfone) or sulphite, at a pH of 14, I preferred Pló of 9.5 to 13. The reaction temperature is advantageously from 40 to 100 ° C. The alkyl amine of C2-O5 is reacted in a molar ratio of the alkyl: anhydroglucose unit from 0.1: 1 to advantageously 4: 1, Depending on the desired degree of substitution for the starch, some of the above-mentioned 11-year-old axes that are used to modify the starch are glycylthiol glyceryl chloride, sulfate or sulfate chloride and 1 lt pmethiarium. , sulfate or sulfate or 3-chloro-2-hydroxypyr-opium chloride, 11-nitric oxide and sulphone my op1-oμ11 sul fatoet 1 lo. The starch compounds which are used to produce the purified regenerated cellulose fihra, which is soluble in water, are easily dispersible in the spinning pulp, preferably in an optional aqueous medium with the aid of the softeners and They exhibit considerable compatibility with viscose. The fluid starch ether is added in an amount of 1 to 20%, preferably 1 to 12% by weight, calculated as a dry substance, based on the cellulose content of the spinning pulp, before coagulation and molding. The filterability of the viscose does not show any deterioration compared to addition-free samples, so that no oration is now observed in the spinning mechanism during the spinning process. ("1 viscose molding <• e leads to or by conventional and known methods, for example by means of spinning mechanisms, a subsequent coagulation bath and opeonal between complementary baths subsequent to the treatment. Another way to produce the regenerated fiber is by stirring or integrating the above-mentioned starch derivatives to the lime and lime, the precursor to the viscose. Again, immediately after the extrusion and extrusion in a coagulating acid bath, a viscose fiber is obtained. The fiber obtained by the methods described can be dyed, after conversion by special treatment to woven and knitted fabrics, by various methods, such as depletion, impregnation and modern stamping processes, such as ink jet processes, use of salt or lcali. The present invention also provides a process for producing a stamped and embossed textile material, composed of regenerated cellulose fiber, which comprises adding said starch ethers to a viscose pulp, cellulose or alcalicellulose solution and spinning the fiber, for example by the process of spinning the viscose or from the cellulose solution, converting the fiber by special treatment to a woven or knitted fabric and dyeing or printing said fabric with one or more reactive dyes in the absence of salt or alkali. dic 1. The textile-modified fiber material used in the dyeing process of the invention may be present in all process states, for example, yarn, cut fiber, coarse wick and goods.
(tissues). The modified textile materials are stamped according to the present invention analogously to the known procedures for dyeing and printing fiber materials with water soluble text and by using known ranges of temperature and usual amounts of dyeing. , except that dyeing solutions, impregnation processes, printing pastes and ink-jet formulations do not require any addition of alkaline compounds, as usual to fix the reactive dyes to the fibers, and the usual additions of salts electrolyte The dyeing or printing therefore takes place at a pH of between 4.5 and 8.5 and, if reagent dyes are used commercially available, in the presence of an electrolytic salt content of 0.01 to 0.5% by weight, based on the dyeing solution. Without the novelty of the cellulose fiber, this electrolytic content would be too low for a factorial satin dye by a factor of 20 to 1000. Suitable dyeing procedures for the purposes of this invention include, for example, the various processes of dyeing. exhaustion, such as dyed on the boat or on the < -Buy with winder or dyeing from long or short bath dyed in dyeing machines- by jet, dyed by procedure, -Batch with reduced pad or by a steam fixation procedure with overcall pad ada. Suitable dyeing processes for the purposes of this invention include tarnishing techniques, for example, ink jet printing and decal printing. The dyes that are used to dye the modified cellulose are generally ammonia in nature. Of particular convenience are textile dyes reactive to the fibers that are capable of reacting with hydroxyl groups, for example, cellulose, or arnmo and thiol groups, for example wool and silk, of synthetic polymers, such as polyesters. licks, or modified polymers, especially the aminated celluloses, to form a covalent bond.
