Definitions
- the invention relates to a particulate product intended for treatment in a medium aqueous textile articles formed at least in part from colored cellulosic materials or not, in order to modify the surface appearance and / or the color.
- the invention also relates to a process for the preparation of such a product.
- the textile articles concerned in the context of this invention are those as that, for example, fabrics, knitwear, certain nonwovens, pants, shirts, skirts and other textile articles, whether or not made up.
- a modification of the surface condition is practiced in acting on the quality of the textile feel, and / or a modification of the color is practiced by lightening the color in a more or less regular and pronounced way, by an effect of washout.
- this type of treatment brings advantages because that it can be implemented in conventional treatment installations, without the transform. It increases the longevity and decreases the pollution of the discharged water, free of fine pumice particles. But this treatment is very long for lead to the heterogeneous washout sought.
- the enzyme that acts according to a gentle hydrolysis of the cellulose, releasing the dye, creating a smooth surface appearance not desired, by eliminating the microfibrils from the support.
- the composition prepared is an enzyme mixture under solid form and solid perlite. This cannot be a homogeneous mixture easily obtained, but more likely a heterogeneous mixture of compounds whose physical properties are different. This heterogeneity is accentuated even more during the transport of the packaged composition, from the production site to the site of use, with the appearance, under the action of vibrations, of a phenomenon of separation and selective grouping of compounds by the effect of their differences in densities, particle sizes and viscosities. Then contradictorily, it seems that the composition is a solid perlite dispersion in the enzyme in liquid form. However, a person skilled in the art knows that this dispersion is impractical due to the very low density of thermally expanded perlite.
- compositions as described appear to the user should be done only by the separate introduction of the various compounds in the aqueous treatment medium in which the textile article to be treated is immersed. Since then, this composition has multiple disadvantages, particularly in terms of its industrial implementation, because it requires the user to obtain the various compounds, to prepare the doses very precisely (in relation to the composition described, but also in relation to the weight of the textile articles to be treated) and to introduce separately into the aqueous treatment medium, at the risk of committing a error in the dosages or an oversight in their introduction.
- a method for the treatment modifying the state of surface and / or color of textile articles formed at least in part from materials cellulosics, colored or not, into which are introduced into the treatment medium textile articles, water and a product comprising at least one cellulolytic enzyme and an expanded perlite is characterized in that the product is formed of particles each composed of both said enzyme and said expanded perlite.
- the particulate product is formed from both a carrier which is perlite and the associated cellulolytic enzyme and preferably adsorbed by the support, under the form of an aqueous composition containing said enzyme, a buffering agent regulating the pH of the medium, optionally a dispersing agent, a dye retention agent and / or pigments.
- a product for the treatment of textile articles formed in less in part of cellulose materials, colored or not, comprising at least one cellulolytic enzyme and an expanded perlite, formed of particles each of which is consisting of a grain of expanded perlite on which the enzyme is adsorbed cellulolytic, is characterized in that each particle additionally contains an agent acting as a pH buffer.
- the process for preparing the product particulate consists in adsorbing an aqueous composition of the enzyme by the expanded perlite.
- the particulate product according to the invention offers, in contrast to the state of the technique, at least two functions simultaneously, the function of the hydrolysis of the cellulose linked to the enzyme and the abrasion function linked to perlite.
- the enzyme is carried by expanded perlite and is brought directly into contact with the articles textiles.
- the synergy of the hydrolysis effect and the abrasion effect is then optimum at a point of attack on the tissue.
- the product is directly implemented by its introduction into the treatment medium in an easily determined amount which is a function of the quantity of textile articles to be treated. And therefore, the introduction of a useful quantity of expanded perlite leads to the introduction of an exact quantity enzyme.
- the textile articles to be treated can be formed entirely of materials cellulosics such as cotton, but they can also be formed in part only said materials, combined with other materials of natural origin, artificial or synthetic, such as for example linen, silk, wool, viscose, acetates and triacetates, polyesters, polyamides, polyolefins, polychlorides of vinyl and others. These textile articles can be unbleached, produced in whole or in part with colored or dyed threads after they are made.
