摘要:
Fluorochemical amine salt compounds containing one or more fluoroaliphatic radicals and one or more salt-forming amino groups which have cyanoalkyl groups as N-substituents groups, such compounds being useful as treating agents for fibrous substrates, such as textiles, e.g., carpet, to modify surface properties thereof, viz., to impart oil and water repellency to the surface of said substrates.
摘要:
Textiles, particularly carpets, are endowed with oil and water repellency and soil resistance by treatment thereof with certain detergent-compatible fluorochemmical compounds which can also be used in conjunction with anionic or nonionic detergents to provide cleaning/treating compositions for cleaning such textiles simultaneously with the treatment. The textile treating compositions of the invention comprise certain detergent-compatible fluorochemical compounds which are dissolved and/or dispersed in a suitable liquid vehicle. The textile treating/cleaning compositions of the invention also contain an anionic and/or a nonionic detergent.

CERTAIN NEAT LIQUID PERFLUOROALKYL ESTERS WERE REACTED WITH CERTAIN NEAT L IQUID POLYAMINES CONTAINING A PRIMARY: SECONDARY:TERTIARY AMINE RATIO OF 1:2:1 TO PRODUCE NEW LIQUID POLYMERIC FLUOROAMIDO-AMINO COMPOUNDS. THE NEW COMPOUNDS WERE DISSOLVED IN CERTAIN SOLVENTS AND APPLIED TO COTTON FABRICS THEREBY IMPARTING TO THE TREATED FABRICS OLEOPHOBICITY WITH RETAINED HYDROPHILICITY WHICH WAS DURAABLE TO REPEATED LAUNDERING.
摘要:
Urethanes consisting of a 2-hydroxy-1,1''-diphenyl ketone having an R-NH-CO-0- group in 4-position and wherein R e.g. represents an alkyl or an aryl radical. These urethanes are useful as stabilizers for organic material and above all as agents for combatting harmful micro-organisms.

PERFLUOROACYLKAMINOHYDROXY AROMATIC COMPOUNDS ARE PROVIDED WHICH ARE OUTSTANDING FOR PRODUCING OIL AND WATER REPELLENT EFFECTS ON TEXTILES AS WELL AS INCREASING THE RESISTANCE TO SOILING BY OILY PARTICULATE SOIL. THE AROMATIC NUCLEUS WHICH MAY CONTAIN 1,2 OR 3 RINGS MAY CONTAIN 1 OR 2 AMINO GROUPS, 1 OR 2 HYDROXY GROUPS AND UP TO 2 HYDROXY METHYL GROUPS. ONE OR 2 OF THE AMINO GROUPS ARE ACYLATED WITH A PERFLUORO ACYL GROUP CONTAINING FROM 3 TO 21 CARBON ATOMS IN WHICH AT LEAST 70% OF THE HYDROGENS HAVE BEEN REPLACED WITH FLUORINE. THE COMPOUNDS MAY ALSO CONTAIN ALKYL SUBSTITUENTS OF FROM 1 TO 5 CARBON ATOMS.
摘要:
A textile having high fluorine adhesion rate, and excellent water- and oil-repellency can be obtained by a method of producing a treated textile, comprising steps of: (1) preparing a treatment liquid comprising a water- and oil-repellent agent which comprises at least one fluorine-containing compound selected from the group consisting of a fluorine-containing polymer or a fluorine-containing low molecular weight compound, (2) adjusting pH of the treatment liquid to at most 7, (3) applying the treatment liquid to a textile, (4) treating the textile with steam, and (5) washing the textile with water and dehydrating the textile, wherein the treatment liquid comprises a thermally gelling substance.
摘要:
Disclosed are partially fluorinated amino acid derivatives useful as organogelators and surface treatment materials to provide oil- and water-repellency properties to substrates. Also disclosed are composite materials, comprising a porous support and a porous nanoweb. The porous nanoweb contains fibrous structures of about 10 nm to about 1000 nm effective average fiber diameter as determined with electron microscopy.
