Definitions
- the invention relates to a method for equipping fibers and textile fabrics with loadable microspheres.
- EP 1,600,210 A1 describes charged microspheres. It involves loading microlo- ves with active ingredients and then applying the loaded microspheres to textile surfaces where they are physically adsorbed without the use of binders. Although this technical solution has a certain resistance to washing, it does not meet the highest requirements.
- WO 2006/015718 A1 describes fibers and textile fabrics which are distinguished in that they are blended with mixtures of (a) hydrophobic active substances and (b) binders.
- drugs without the mediation of microcapsules or the like are applied to textile surfaces, but not directly, but by means of film-forming polymers (binders).
- This technical solution lacks a controlled release of the active ingredients.
- wash permanence is to be understood that the above-mentioned desirable properties of the textiles are lessened by washing only to a limited extent.
- the invention relates to a process for finishing fibers and textile fabrics with (a) absorbent microspheres and (b) film-forming polymers (binder), wherein component (a) is fixed on the textile surface by means of component (b) you (1) preparing an aqueous dispersion of the microspheres (a) using alkali and / or alkaline earth metal soaps of fatty acids having 6 to 24 carbon atoms as dispersants, these fatty acid soaps either being used as such or prepared in situ from fatty acids and alkali hydroxides, (2) incorporating fibers or fabrics into the dispersions so prepared, if desired, further diluting with water,
- the dispersion prepared in step (1) is diluted with water in step (2).
- Step (1) has the purpose of producing an aqueous dispersion of the microspheres (a), it being understood that it is a solid dispersion.
- step (2) textile is introduced into the dispersion thus prepared.
- step (3) is achieved by lowering the pH, that the dispersants are converted into the acidic form; thus they lose their dispersing activity, with the result that the microspheres (a) virtually "fail", which they do in such a way that they deposit on the textile.)
- Step (4) has the purpose of making the microspheres (a), which were applied to the textile in step (3) to bind permanently to the textile.
- the alkali and / or alkaline earth metal soaps of fatty acids of 6 to 24 carbon atoms used in step (1) are selected to have an HLB value in the range of 8 to 25.
- the alkali and / or alkaline earth metal soaps of fatty acids having 6 to 24 carbon atoms are prepared in situ by reacting the desired microspheres (a) with one or more fatty acids having 6 to 24 carbon atoms. Mixed atoms, then adding water and the fatty acids by addition of alkali and / or alkaline earth metal hydroxides in the corresponding soaps transferred.
- the dispersion prepared in step (1) contains 1 to 90% by weight, based on the total dispersion, of microspheres (a).
- the dispersion prepared in step (1) preferably contains from 10 to 70% by weight and in particular from 30 to 60% by weight, in each case based on the total dispersion, of microspheres (a).
- liquor ratios set in step (2) are not critical per se. In a preferred embodiment, liquor ratios in the range of 1:10 and 1:15 are set in step (2).
- liquor ratio is known to the person skilled in the art. This is understood to mean the ratio of the amount of textile to the volume of water in the machine used for the equipment.
- the invention is not subject to any particular limitations with regard to the acids to be used in step 3, provided that it is ensured that these acids are capable of converting the alkali and / or alkaline earth metal soaps of said fatty acids used as dispersants into the free fatty acids.
- the acid from the group acetic acid, lactic acid and glycolic acid is selected in step (3).
- the lowering of the pH occurring in step (3) is preferably carried out slowly. This ensures that the microspheres (a) are applied to the textile in very high quantities.
- the lowering of the pH in step (3) takes place at a rate such that the microspheres (a) are applied to the textile in amounts of at least 70% and in particular of at least 80%, based on the total amount in the liquor existing microspheres (a) - takes place.
- microspheres (a) may be unloaded or partially loaded with drugs or fully loaded. They fulfill the function that they can be loaded by the user as desired and, after release of the active ingredients, can also be reloaded as desired.
- Absorbent microspheres are structures that have a largely homogeneous structure.
- the absorbent microspheres used in the context of the present invention have the property of being able to take up active substances and also release them again, with both occurring several times can, ie agents can be absorbed by loading or reloading and released over time again. Because of this property, these microspheres are referred to as absorbent microspheres.
- the active substances can be adsorbed on the surface of the microspheres and / or in the microspheres microspheres are dimensionally stable, ie they are not destroyed during the release of the active ingredients, and it should be expressly stated that microcapsules, which are destroyed when the active substances are released, are not included in the definition to fall from microspheres.
- the central point of the technical solution proposed by the present invention is a combination of several factors:
- the microspheres act as containers for drugs.
- microspheres are dimensionally stable and are not destroyed by release of the active ingredients.
- microspheres can be reloaded several times - even with different active substances - (reload).
- the microspheres are fixed by - one or more - film-forming polymers on the textile surface, resulting in a relative to the prior art, relative improvement of the washing permanence.
- microspheres are preferably spherical in shape, but are not limited in geometry to spheroidal shape, but may have other spatial shapes, for example, they may represent rotatiosellipsoids or have a rod shape.
- microspheres preferably have an average particle size in the range of 1 to 15 microns, and more preferably 5 to 10 microns.
