Definitions
- the present invention relates to a process for the optical brightening of synthetic fibers or of synthetic fibers in a mixture with natural fibers, the synthetic fibers or mixtures of the synthetic fibers with natural fibers being treated in a treatment bath containing optical brighteners to which a microemulsion has been added ,
- optical brighteners are known for their ability to give textiles or plastics a white color.
- EP 0023 026 discloses compounds of the general formula I.
- radicals R 1 and R 2 can be, for example, H, F, Cl, phenyl, CF 3 , alkyl or numerous other radicals, and where V is selected from
- a disadvantage of using compounds of general formula I as optical brighteners is that their low temperature yield is limited, i.e. you need a lot of product to achieve the desired brightening effect.
- EP-A 0 023 027 and EP-B2 0 032 917 disclose the use of mixtures of two or more dicyanostyrylbenzene compounds for the optical brightening of polyesters.
- DE 102 19 993 AI relates to a process for lightening textile materials, in which compounds of the general formula I, a dicyanostyrylbenzene compound and one
- the optical brightening of textile materials is generally carried out by the pull-out or thermosol process.
- the textile material to be lightened is usually padded with an aqueous liquor which contains the optically lightening substances, optionally a blue or violet shading dye or mixtures thereof and optionally additives (see above).
- the liquor intake is generally 30 to 100%.
- the textile material is then dried and fixed at a temperature of 150 to 200 ° C for 5 to 60 seconds.
- thermosol process A disadvantage of the thermosol process is that the fixing temperature of 150 to 210 ° C, in particular of 170 to 190 ° C, requires a high level of energy. At these high fixing temperatures, additives or any contaminants adhering to the textile material from previous treatment steps smoke and lead to gaseous emissions. Despite the high temperatures, only a ring brightening is achieved in the thermosol process, which is inferior to that of a pull-out coloring in terms of whiteness. In the case of mixtures of the chemical fibers with natural fibers or with synthetic cellulose fibers, the natural fiber or synthetic cellulose fiber may brown.
- Another known process is the exhaust process, in which the aqueous liquor is usually used at temperatures of 90 to 135 ° C.
- the textile material to be lightened is usually brought into an aqueous liquor at a temperature of 10 to 50 ° C, which contains the optically brightening Bonds, optionally a blue or violet shading dye or a mixture thereof and optionally additives, for example dispersants, carboxylic acids or bases, and the pH value of which is usually 3 to 12, preferably 3 to 8.
- the liquor ratio (weight ratio of textile material: liquor) is 1: 1.5 to 1:40, preferably 1: 5 to 1:20.
- the bath is then heated to a temperature of 95 to 135 ° C. within 15 to 60 minutes and held at this temperature for 15 to 60 minutes.
- the lightened textile material is then rinsed and dried.
- the HT process high temperature process is usually used. If the color transition temperature of the polyester is exceeded sufficiently, the lightening process must be carried out by 130 ° C in order to achieve a lightening effect which is sufficient in practice. Since the lightening takes place in the aqueous medium, an autoclave, a high-pressure apparatus or a high-pressure machine must be used. Disadvantages include that such a unit is more expensive than an open unit, that the heating and cooling time and thus the machine occupancy is long and that the amount of energy required, especially for heating to 130 ° C, is very high.
- Carriers are often formulations based on emulsifiers, sometimes solvents and the active component.
- Active components are compounds based on liquid, halogenated benzene derivatives, alkyl aromatic compounds, aromatic hydroxy compounds, aromatic alcohols, ketones, carboxylic acids and their esters, alkyl phthalimides or substituted phenyl glycols and their esters.
- the most important active components are 1,2-dichlorobenzene, 1,2,4-trichlorobenzene, 2-phenylphenol, diphenyl, diphenyl ether, methyl, butyl or benzyl benzoates, methyl salicylates, dimethyl phthalates, phthalic acid N-butyl imides or chlorophenoxyethanol.
- the Carrier process brings excellent white effects in a short brightening time with a lower brightening temperature and thus lower energy consumption.
- carriers can cause stains.
- carriers are often carcinogenic.
- a low-temperature process has been developed as an alternative to the carrier process.
- mixtures of nonionic and ionic surfactants with aliphatic or aromatic dicarboxylic acid esters are used instead of the carcinogenic carriers. These mixtures are not fiber-active, but they increase the solubility of the brighteners in the dyeing liquor and thus enable them to be brightened at 98 to 110 ° C.
- the mixtures of non-ionic and ionic surfactants with aliphatic or aromatic dicarboxylic acid esters are also known as diffusion accelerators, ie they accelerate the diffusion of the brighteners from the dye liquor into the fiber.
- the process has several disadvantages: when diluted, the diffusion accelerators go through a swelling phase, which affects the homogeneous distribution in the lightening bath.
- the resulting whiteness is inferior to that of carrier lightening.
- the whitening effect quickly decreases at brightening temperatures below 100 ° C. If acceptable white effects are achieved at 98 ° C, the resulting whiteness at 95 ° C is no longer sufficient for many requirements.
- temperatures above 95 ° C cannot often be reached in open aggregates in an aqueous medium.
- the object of the present invention is to provide a lightening process which can be used in open aggregates, which achieves excellent degrees of whiteness, which is free of toxic or carcinogenic auxiliaries, which avoids liquor inhomogeneities (in particular due to swelling phases of surfactants) and which at temperatures around 95 ° C still produces excellent white effects.
- This object is achieved according to the invention by a process for the optical brightening of synthetic fibers or of mixtures of synthetic fibers with natural fibers, the synthetic fibers or mixtures of synthetic fibers with natural fibers in a treatment bath containing optical brighteners to which a microemulsion has been added was treated.
- microemulsions are already used as leveling aids in dyeing polyester in textile form. Dyeing of polyester in textile form often becomes u-negative, uneven, stained. Such irregularities can be prevented or significantly reduced by adding microemulsions to the staining solutions.
- the addition of the microemulsion stabilizes the disperse dye particles and controls the molecular transport process to the fiber and the dissolving process of the dye molecules in the polyester fiber.
- Another task of the microemulsion is to control the dilution process when preparing the dye liquor so that no highly viscous intermediate states are obtained. In the optical brightening of synthetic textile materials, there are usually no irregularities or they cannot be recognized by the sluggishness of the eye.
- microemulsions have no leveling effect when optically brightening synthetic fiber materials, they act as diffusion accelerators, ie the required fixing temperature, for example with polyester, can be reduced by approx. 35 ° C from approx. 130 ° C to approx. 95 ° C. without a noticeable reduction in whiteness.

- the bath was then heated to 95 ° C. in the course of 30 minutes and held at this temperature for a further 30 minutes.
- the liquor was then stirred the staple fiber yarn was removed from the bath, rinsed and dried, and the optical whiteness was determined according to the CIE for analysis.
- the resulting whiteness levels are as follows:
- polyester / viscose knitwear (mixing ratio 50% polyester and 50% viscose) were introduced at 25 ° C. into 100 ml of a brightening bath which contains 0.04 g of a brightener dispersion.
- the brightener dispersion contains the following optical brighteners.
- the resulting whiteness levels are as follows:
- polyester staple fiber yarn were introduced at 25 ° C. into 100 ml of a whitening bath which contains 0.25 g of a brightener dispersion.
- the brightener dispersion contains the following optical brighteners
- the resulting whiteness levels are as follows:
