Abstract: The present invention relates to a polymerisable composition for bonding fibre units, in particular linear textiles such as filaments, yarns, twines or ropes, comprising at least one prepolymer having at least two polymerisable vinylidene groups, such as a polyurethane having at least two (meth)acrylate groups, at least one photoinitiator and at least one compound having at least one polymerisable vinylidene group with a weight average molecular weight of 70-800 g/mol. In addition, the present invention relates to a process for bonding fibre units, comprising applying the composition according to the invention to at least one fibre unit such as a filament, yarn, twine or rope and irradiation of the fibre unit thus obtained with radiation having a wavelength in the range of, for example, 100-450 nm.

Abstract: The present invention relates to core-shell particles comprising a core comprising at least one lipophilic compound and a shell comprising at least one layer close to the core and one layer far from the core. The invention further relates to the preparation of such core-shell particles and their use, particularly in the finishing of fibers and textiles.

Abstract: Preparations of a polyurethane and/or polyurea and a copolymer which are hydrophobic contain at least one conversion product (S), at least one copolymer (C), optionally at least one (blocked) polyisocyanate, optionally a solvent, and optionally at least one surface-active substance. The conversion product (S) may be the reaction product of at least one compound (A) with at least one unblocked or at least partially blocked di-, tri- or polyisocyanate (IC). The compound A may be the reaction product of a polyhydric alcohol with a carboxylic acid or with an alkylisocyanate, or a reaction product of an alkanolamine and/or alkylamine (a3) with a carboxylic acid and/or alkylisocyanate. The highly hydrophobic preparations may be applied to textiles without negatively influencing a subsequent adhesion of the textile substrate or the membrane permeability of the substrate even after thermal treatment, and exhibit very good wash permanence on the substrates.
