摘要:
Described are 8 aqueous compositions useful for treating textile materials to impart oil- and/or water-repellent properties thereto. The compositions contain inter alia polymers containing perfluoroalkyl groups (R F groups), wherein 55 to 100% of the R F groups contain 6 carbon atoms.
摘要:
A process for producing an aqueous emulsion of a polyolefin having a weight-average molecular weight of 20,000 or higher, characterized in that an ester of a styrene/maleic anhydride copolymer or/and styrene/maleic acid copolymer is used as a polymeric dispersant.
摘要:
Compositions for treating fabric. The compositions of the present invention may be used to improve various properties of fabrics such as the olfactory perception and/or appearance of the fabric without requiring that the fabrics be put through an entire standard laundry process. Methods of treating the fabrics are also disclosed.
摘要:
The invention relates to a method for treating surfaces, characterized in that the surface is treated using (a) at least one hydrophobing agent, (b) at least one cross-linked organic copolymer in particulate form, (c) at least one emulsifier, without the use of acrylate or polyurethane binding agents, and is dried subsequent to the treatment.
摘要:
The present invention provides an aqueous composition comprising: (a) a melamine that is at least partially derivatised with an aliphatic hydrocarbon group having at least 8 carbon atoms; (b) a wax; and (c) at least one component selected from the group consisting of (i) a reaction product of an aliphatic polyisocyanate and an organic compound having one or more groups capable of reacting with an isocyanate, said reaction product having free isocyanate groups and having a molecular weight of at least 350 g/mol and (ii) a blocked aromatic polyisocyanate. The compositions can be used to treat textile to provide good water repellency properties thereto.
摘要:
The invention relates to a two-step method for dipping a synthetic fiber wherein the fiber is first dipped with an aqueous pre-dip composition followed by a dip with resorcinol-formaldehyde latex (RFL) composition, characterized in that the pre-dip composition comprises a blocked isocyanate having at least tri-functional isocyanate groups and a latex wherein the ratio by weight of blocked isocyanate and latex is between 9 and 0.7, preferably between 4 and 1. The invention further pertains to a pre-dip composition for dipping a synthetic fiber, comprising a blocked at least tri-functional isocyanate compound and a latex, further comprising water, an emulsifier, and 2-vinyl pyridine copolymer and to a fiber, cord, and composite article of rubber and fiber or cord, wherein the fiber or cord has distributed over at least a surface portion thereof (1) blocked tri-functional isocyanate compound, preferably HDI-trimer; (2) an RFL adhesive; and (3) an in situ vulcanized rubber compound.
