摘要:
Die Erfindung betrifft ein Verfahren zur Stabilisierung von Cellulosefasern und/oder eines Cellulosefasern enthaltenden Materials, insbesondere einer textilen Warenbahn enthaltend Cellulosefasern, dadurch gekennzeichnet, dass die Cellulosefasern mit einer Behandlungslösung in Kontakt gebracht werden, wobei die Behandlungslösung umfasst: (a) eine wasserbindende Komponente, (b) ein Quellmittel, sowie (c) Wasser. Durch das erfindungsgemässe Verfahren werden Cellulosefasern erhalten, welche in ihren Eigenschaften mit denen durch konventionelle Ammoniakbehandlung gemäss Stand der Technik erzielbaren Resultaten vergleichbar oder diesen überlegen sind.
摘要:
Disclosed is a method for the production of three-dimensional silk products, wherein a three-dimensional silk product is treated with a silk solvent for a limited period of time so that a partial disintegration of the silk product is obtained whereafter the partially disintegrated silk product is re-stabilised with physical β-sheet induction by a re-stabilising solution.

Disclosed is a method for the production of two- or three-dimensional silk products, wherein a two- or three-dimensional silk product is treated with a silk solvent for a limited period of time so that a partial disintegration of the silk product is obtained whereafter the partially disintegrated silk product is re-stabilised with physical beta-sheet induction.
摘要:
A carrier system for transporting functional chemicals into substrates, such as fiber and plastic materials, comprises a carrier compound and at least one functional chemical, wherein the carrier compound is composed of micelles, liposomes, lyotropic liquid crystals or intercalation compounds. The functional chemical transported by the carrier compound migrates into the substrate and has anisotropic distribution therein. The invention further relates to a method for modification, activation and deactivation for subsequent application onto substrates.

Disclosed is an anti-viral member which can inactivate a virus. Specifically disclosed is an anti-viral member which is characterized by comprising a base material, univalent copper compound microparticles, and inorganic microparticles which are provided for the purpose of retaining the univalent copper compound microparticles on the base material and each of which has a silane monomer bound to the surface thereof via a chemical bond, wherein the inorganic microparticles are bound to one another via chemical bonds formed between the silane monomers provided on the surfaces thereof, and each of the inorganic microparticles is bound to the base material via a chemical bond between the silane monomer and the base material to form spaces inwhich the univalent copper compound microparticles are to be retained. The anti-viral member has an extremely high anti-viral activity compared to those achieved by the conventional binder immobilization techniques, and is applicable to various materials or various products to which the materials are applied.
摘要:
Polymères solides dont la partie en surface a été modifiée par une réaction avec des réactifs produisant des ions ou des radicaux libres thiocyano ou isothiocyano. Est également décrit un procédé de préparation de ces polymères modifiés. Ces polymères augmentent les forces d'adhésion des stratifiés les contenant, améliorent l'adhérence des peintures, augmentent la viscosité et la perméabilité aux gaz altérés, en comparaison des polymères non modifiés.
