20130102943 | RELOADABLE FINISHES FOR TEXTILES AND FORMULATIONS FOR LOADING SUCH FINISHES - A polymer compound according to the invention comprises an acrylic acid copolymer composed of acrylic acid derivatives and/or methacrylic acid derivatives, containing: a) at least one acrylic acid derivative and/or methacrylic acid derivative substituted with a sulfonic acid group; b) at least one hydrophilically substituted acrylic acid derivative and/or methacrylic acid derivative; c) at least one lipophilically substituted acrylic acid derivative and/or methacrylic acid derivative; and d) at least one acrylic acid derivative and/or methacrylic acid derivative which acts as a crosslinking agent. In the method according to the invention for loading textile products with a low-molecular compound, a) a textile product is provided with a finishing layer whose accessible surface has a negative charge; and b) the textile product is brought together with an emulsion or active substance solution, for example by immersing the textile product in the emulsion/solution, or by spraying the emulsion/solution on the textile product. At least one low-molecular compound is contained in the dispersed phase of the emulsion, and the surface of the particles of the dispersed phase has a positive charge. | 04-25-2013 |
20110021098 | Finishing of Substrates - A method is described for manufacturing a finish formulation for the hydrophobic and/or oleophobic finishing of surfaces, comprising a dispersant incorporating dispersed, activated particles with hydrophobic and/or oleophobic surface groups and a binder, in which particles with hydrophobic and/or oleophobic surface groups are comminuted in the dispersant for activation, and the binder is added before or after activation. | 01-27-2011 |
20100292623 | POLYETHYLENIMINE NANOPARTICLE-CONTAINING MICROBICIDAL ELECTROSPUN POLYMER FIBERS FOR TEXTILE APPLICATIONS - The present invention relates to a process for producing electrospun fibers comprising polyethyleneimine nanoparticles (PEIN). The use of PEIN permits the antibacterial finishing of electrospinnable polymers, provided that these polyethyleneimine nanoparticles are particles of derivatized polyethyleneimine (PEI), since pure underivatized PEI has no antibacterial action. Preference is given to using quaternized polyethyleneimine. The electrospinnable polymers can be coated with PEIN during and/or after the electrospinning. The polymeric fibers obtainable by the process according to the invention can be used for textile fibers, for example for the production of fibers for functional apparel or for fibrous nonwoven webs or fibrous mats for cell culture substrates. | 11-18-2010 |
20090137171 | FINISHING OF TEXTILE FIBERS, TISSUES AND FABRICS - A method is provided for the application of a finishing layer to a textile support material. A water repellent or oil repellent layer, a so-called finishing layer, is applied to a textile support material selected from the group of fibers, tissues and fabrics. The water repellent or oil repellent finishing layer comprises at least two water repellent or oil repellent components wherein a first component comprises one or more dispersants and a second component comprises one or more dispersed phases or colloids, and wherein the dispersant and the dispersed phase are present in the gel state. Additionally, textile articles are proved having the novel water repellent or oil repellent finishing layer which are equal on a high level or even superior with respect to their functional properties to products prepared according to known finishing methods and at the same time allow a complete or partial substitution of the health and environmentally hazardous standard chemicals employed nowadays by novel compounds which have not been used to date. | 05-28-2009 |
20080214075 | Finishings For Textile Fibers and Fabrics to Give Hydrophobic Oleophobic and Self-Cleaning Surfaces - Methods for coating fibers and material to achieve particular properties such as water repellency, oil repellency and self-cleaning, are provided. These properties are achieved by pre-treating the fibers or material and subsequently coating with prepolymers and nanoparticles. The prepolymers are partly substituted with hydrocarbon groups or fluorocarbon groups. The nanoparticles may have surfaces treated with hydrocarbons or fluorocarbons. The prepolymers are fixed and hardened by irradiation with light of a wavelength in the UV or visible regions. | 09-04-2008 |
