摘要:
The present invention relates to a mat of polymer fibres capable of trapping formaldehyde which contains at least one dihydrazide. Another subject of the invention is the use of said mat, in particular as a surface covering for thermal and/or sound insulation products, in particular based on mineral wool, polystyrene or on an organic or inorganic foam.

Die Erfindung betrifft eine flammhemmend modifizierte Hohlfaser mit einer silikonfreien Weichgriffausrüstung, sowie ein Verfahren zur Herstellung derselben und deren Verwendung für Füllfaserprodukte, insbesondere in Faserfüllungen für Bekleidung, Kissen, Möbel, Dämmung, Steppdecken, Filter, Polsterungen (z.B. in Autos), Schlafsäcke, Matratzenauflagen und Matratzen. Bei den für diese Anwendungen verwendeten Hohlfasern handelt es sich im Allgemeinen um Hohlfasern, die mit phosphorhaltigen Verbindungen flammhemmend ausgerüstet sind. Als Hohlfasern werden bevorzugt Polyesterhohlfasem verwendet.

Para-type aromatic polyamide short fibers are attached with a phosphate ester alkali metal salt of an alcohol having a carbon number of 12 having a molar fraction of a monoester salt of from 45 to 70% by mol and a molar fraction of a diester salt of from 10 to 40% by mol in an amount of from 0.05 to 1.0% by weight based on the weight of the fibers, whereby such para-type aromatic polyamide short fibers excellent in spinning property are obtained that are excellent in bundling property and antistatic property, and are low in adhesion property causing less twining on rollers and less formation of scums.

According to the present invention, curable compositions comprising (i) one or more polyacid containing at least two carboxylic acid groups, anhydride groups, or salts thereof; (ii), optionally, one or more polyol containing at least two hydroxyl groups; and (iii) one or more reactive β-hydroxyamide group containing polyol, which is the reaction product of a lactone or cyclic ester and an alkanolamine, of the following formula (I):
in which, R and R" independently represent H, or any monovalent C 1 to C 18 linear or branched alkyl radical, which radical may comprise one or two aryl or cycloalkyl group, one or more hydroxyl, amine, thiol, amide, carboxyl or alkenyl group, or combinations thereof; R' represents either a covalent bond or a divalent C 1 to C 5 alkylene radical where the alkylene radical may bear alkyl group substituents; y is the integer 1 or 2; x is 0 or 1, such that (x + y) =2; wherein the ratio of the number of equivalents of said carboxylic acid groups, anhydride groups, or salts thereof to the number of equivalents of said hydroxyl groups is from 1/0.01 to 1/3. The curable compositions of the present invention provide less corrosive, low energy curing binders. Further, the present invention provides methods to use the compositions as aqueous binders for composites, nonwoven and woven substrates, and the products produced thereby.

The invention relates to a method for applying a finishing layer to a textile carrier material. According to the inventive method, a water repellent layer or oil repellent layer, a so-called finishing layer is applied to a carrier material of the group of fibres, tissues and fabrics. The water or oil repellent finishing layer comprises at least two water or oil repellent components. A first component comprises at least one dispersing agent and a second component comprises at least one dispersed phase or a colloid. The dispersing agent and the dispersed phase are present in a gel state. The colloids of the dispersed phase are distributed in the dispersing agent in an anisotropic manner in such a way that the colloids are present in a concentrated form in the region of the finishing surface which forma a phase boundary layer between the finishing layer and the surrounding atmosphere. According to the finishing method and a first step thereof, the dispersion that is present as a colloidal solution is applied to the carrier material and is converted into a gel state in a subsequent step. The components of the dispersion are provided with an inherent capability of self-organisation. Said capability is used for obtaining the anisotropic distribution. The invention also relates to textile articles being provided with the novel water or oil repellent finishing layer. Said articles are equal or superior to products produced according to known finishing methods, with respect to the functional characteristics thereof and on the highest level. Said articles enable the chemicals which are ecologically harmful, might be harmful to health and are conventionally used to be entirely or partially replaced by novel compounds that are not in use until now.

The present invention is generally directed to a process for making fabrics containing cotton fibers more aesthetically pleasing and resistant to staining by anionic dyes by derivatising the cotton so that it exhibits a permanent anionic charge. By increasing the anionic charge of the fibers, the fibers become resistant to anionic coloring agent which may undesirably come into contact with the fibers and the fibers can absorb greater amounts of cationic softeners and biocides. Furthermore, the negative charges repel each other resulting in a fabric with greater loft and hydrophilicity. This results in greater smoothness, better hand, and more comfort. Besides being used to prevent the cross-staining of fabrics, the present invention can also be used to make carpet materials resistant to anionic staining agents.
摘要:
Aqueous esterquat dispersions with improved wetting power are obtained by quaternising fatty acid alkanol amine esters in the presence of dispersant mixtures containing (a) alcohol polyethylene glycol ether of the formula (I) R1O(CH2CH2O)nH in which R1 is a linear or branched alkyl and/or alkenyl radical with 6 to 22 carbon atoms and n is a number from 1 to 10, and (b) fatty acid amidoalkylene amines of the formula (II) R2CO-NH(Z)NR3R4 in which R2CO is an acyl radical with 2 to 18 carbon atoms and 0 and/or 1 to 3 double bonds and Z is a linear or branched alkylene group with 2 to 4 carbon atoms and R?3 and R4¿ are mutually independently hydrogen or alkyl radicals with 1 to 4 carbon atoms, and then adding them to water.
