Definitions

• the invention relates to a method for producing aminated cotton fibers.
• European laid-open specification EP 0 546 476 A1 describes a "process for producing a modified fiber material and a process for dyeing the modified fiber material with anionic dyes".
• the fiber material is modified in such a way that an aliphatic or cyclic compound containing amino and ester groups is applied to the material and subjected to a thermal treatment. Another possibility is to leave the material in such a solution for a long time at an elevated temperature.
• the materials to be modified are ready-to-dye, ie boiled and bleached cotton and cotton blended fabrics. This procedure, namely to subsequently modify ready-to-use materials in order to then dye them free of salt and alkali, is very uneconomical and unecological in a total cost calculation.
• This object is achieved by a process for the production of aminated cotton fibers, characterized in that raw cotton or raw cotton-polyester mixtures are simultaneously boiled, boiled or dry mercerized by the addition of one, if necessary, by 1 or 2 or more hydroxyl-substituted, saturated aliphatic compound of 3 to 15 carbon atoms with at least one primary, secondary, tertiary or quaternary amino group and at least one hydrolyzable ester group in which the saturated radical (s) branches in a straight chain and / or is (are) and can optionally be interrupted by one or more hetero groups, modified.
• esters groups of the compounds containing amino groups are a sulfato or phosphato group or a C1-C4-alkanoyloxy group, phenylsulfonyloxy or one on the benzene nucleus by substituents from the group carboxy, C1-C4-alkyl, have proven to be favorable C1-C4 alkoxy and nitro substituted phensulfonyloxy group.
• N can also be used advantageously - ( ⁇ -Sulfatoethyl) piperidine, 2-sulfato-3-hydroxy-1-aminopropane, 3-sulfato-2-hydroxy-1-aminopropane, 1-sulfato-3-hydroxy-2-aminopropane , 3-Hydroxy-1-sulfato-2-aminopropane, 2,3-disulfato-1-aminopropane or 1,3-disulfato-2-aminopropane, a derivative of these compounds with another ester group mentioned above instead of that Sulfato group, especially N- (2-sulfatoethyl) piperazine sulfate.
• those amino compounds that have an ⁇ -chloro- ⁇ -hydroxy substitution as a reactive residue on the amine component are also suitable for the modification of raw cotton articles.
• compounds which can react with hydroxyl groups, for example cellulose, or amino and thiol groups, for example wool and silk, and which are capable of forming a covalent chemical bond are also suitable for the modification of raw cotton articles.
• the modification during the brewing or boiling of raw cotton articles can be carried out continuously or discontinuously.
• Soda lye with about 5 to 30 g / l NaOH is used as the baking or decoction liquid in a batch process. It is preferably carried out in closed tanks at temperatures between 80 ° C and 120 ° C, preferably 90 and 102 ° C.
• the pretreatment agent can be added linearly, degressively or directly.
• the concentrations are between 10 and 100 g / l, preferably 15 to 30 g / l.
• the modification according to the invention in discontinuous form can directly follow a bleaching process with hydrogen peroxide by adding the amount of alkali required for the pretreatment to the bleaching solution, thereby destroying excess bleaching agent and then adding the modification agent. It has proven to be advantageous if no peroxide stabilizer is added to the bleaching solution.
• the amounts of NaOH fluctuate between 5 to 20% by weight, based on the weight of the goods, depending on the type of energy supply and the type of fleet order.
• Based on the weight of the goods between 2 and 10% by weight, preferably 3 and 8% by weight, of modification agent are used.
• the modification according to the invention can directly follow a continuous bleaching process by squeezing an alkaline active substance solution which has been strengthened two to three times compared to a conventional liquor onto the pre-bleached, still very moist material and then subjecting the goods to a steaming process.
• No stabilizer should be added to the solution for the pre-bleaching in order to ensure that after squeezing the strongly alkaline modification liquor, the hydrogen peroxide is quickly destroyed and thus no fiber damage occurs.
• the textile fiber material that is used in the pretreatment process according to the invention can be present in all processing states, such as yarn, flake, sliver and piece goods (fabric).
• An essential and surprising advantage of the method according to the invention is that the fiber damage that always occurs in the course of boiling or baking processes is significantly reduced during pretreatment with said modification agents.
• Mercerization processes are also suitable for modification.
• the preferred embodiment is dry mercerization by squeezing a sodium hydroxide solution of 22 to 32 ° Be, preferably 24 ° Be, which contains between 30 and 120 g of modification agent per liter, onto the fabric.
• the goods are then over dried on a stenter with hot air at 120 ° C.
• a wash-out process a material is obtained which has an increased gloss and can be dyed free of salt and alkali according to the invention.
• Another embodiment is the impregnation with hot, modification agent-containing liquor. Following the hot impregnation the goods pass through a roller marking compartment. Contrary to common techniques, the temperature should be kept between 80 and 95 ° C for a longer period during the swelling and in the subsequent stabilization zone.
• the dyeing of the aminated cotton fibers according to the invention is carried out analogously to known dyeing methods and printing processes for dyeing and printing fiber materials with water-soluble textile dyes and using the temperature ranges and customary amounts of dye known to be used for this.
• the particular advantage here is that the dye baths, padding processes, printing pastes and ink-jet formulations do not require the addition of alkaline compounds, as are usually used for fixing fiber-reactive dyes, and furthermore also the usual additions of electrolyte salts can be dispensed with.
• Dyeing processes which can be used according to the invention are, for example, the various exhaust processes, such as dyeing on the jigger and on the reel runner or dyeing from a long and short liquor, dyeing in jet dyeing machines, dyeing by padding-cold dwelling or padding -Hot steam fixing process.
• the dyeing methods which can be used according to the invention also include the printing techniques, including ink-jet printing and transfer printing.
• the dyes used to dye the aminated cotton fiber are generally anionic in nature.
• the fiber-reactive textile dyes which can react with hydroxyl groups, for example of cellulose, or amino and thiol groups, for example of wool and silk, of synthetic polymers, such as polyamides, or also modified polymers, namely the aminated celluloses, and a covalent bond are particularly suitable able to enter.
• the fiber-reactive component on the textile dyes are, in particular, the sulfatoethylsulfonyl, vinylsulfonyl, chlorotriazinyl, fluorotriazinyl, trichloropyrimidyl, difluorochloropyrimidyl, Dichloroquinoxalinyl, chloropropylamidyl, ⁇ -bromoacrylamidyl and combinations of these “anchor systems” are mentioned.
• Cotton twill pre-desized, raw white, weight 200 g / kg is mixed with an aqueous liquor containing 60 parts sulfatoethylpiperazine, 100 parts sodium hydroxide, 5 parts ®Hostapal FA (trade name of a nonionic wetting and detergent) and 6 parts ®Ladit RBO in 1000 parts Contains water, impregnated.

• the temperature treatment is followed by a three-time washing process, the washing solution optionally being able to contain a commercially available surfactant, at boiling temperature, in order to remove the water-soluble impurities present on the fabric.
• the cotton material After rinsing with warm and cold water, the cotton material is dried. This gives a textile fabric with a degree of desizing of 9 (Tegewa rating) and a suction head of 6.5 cm after 300 minutes, which can be processed directly in a dyeing process using the block process.
• an aqueous dye solution containing 20 parts of the dye of the formula known from European Patent Application 158 233, Example 1, and 3 parts of a commercially available nonionic wetting agent dissolved, applied to the fabric at 25 ° C by means of a pad with a liquor absorption of 80%, based on the weight of the fabric.

• cold and hot water which may optionally contain a commercially available surfactant, and then optionally again with cold water Rinsed water and dried.
• a strong, uniformly colored yellow coloration is obtained which has good general fastness properties, in particular good fastness to rubbing and light.
