A scaffold may comprise a first polymeric electrospun fiber comprising a first material having a first degradation rate, and a second polymeric electrospun fiber comprising a second material having a second degradation rate different from the first degradation rate. The first degradation rate may substantially correspond to a cell infiltration rate, and the second degradation rate may be slower than the first degradation rate. Such a scaffold may be manufactured by electrospinning a first polymer fiber having a first degradation rate by ejecting a first polymer solution from a first polymer injection system onto a mandrel, and electrospinning a second polymer fiber having a second degradation rate different from the first degradation rate by ejecting a second polymer solution from a second polymer injection system onto a mandrel. Wound healing may be improved by applying such a scaffold to a portion of a wound.

Trim part for a vehicle, comprising at least a fibrous layer comprising of thermoplastic bicomponent filaments or staple fibers, consisting of a first polymer forming the sheath of the bicomponent filament or staple fiber and a second polymer forming the core of the bicomponent filament or staple fiber and whereby the fibrous layer is consolidated by heating thereby melting the sheath polymer forming binding points between the filaments or staple fibers, characterized in that at least the sheath of the bicomponent filament or staple fiber comprises a shrinkage reducing additive being at least a polysiloxane, preferably a polydimethylsiloxane.

A method for forming porous fibers is provided. The fibers are formed from a thermoplastic composition containing a continuous phase, which includes a matrix polymer, and a nanoinclusion additive that is at least partially incompatible with the matrix polymer so that it becomes dispersed within the continuous phase as discrete nano-scale phase domains. The method includes traversing a bundle of the fibers through a multi-stage drawing system that includes at least a first fluidic drawing stage and a second fluidic drawing stage. The first drawing stage employs a first fluidic medium having a first temperature and the second drawing stage employs a second fluidic medium having a second temperature. The first and second temperatures are both lower than the melting temperature of the matrix polymer, and the first temperature is greater than the second temperature.

A textile product and a method for manufacturing thereof are discussed. The textile product comprises about 5-95% natural down clusters by weight and about 95-5% of a secondary fiber material by weight. The method for manufacturing the textile product includes opening a fiber material, adding natural down clusters to the fiber material, mixing the fiber material with the natural down clusters to form a homogeneous mixture, and filling the textile product with the homogeneous mixture.

The invention relates to a polymer fibre with improved dispersibility, a method for producing said fibre and the use of said fibre. The polymer fibre according to the invention comprises at least one synthetic polymer and 0.1 and 20 wt. % of a silicone. The polymer forming the fibre forms a solid dispersion medium at room temperature (25 C.) for the silicone present in solid form also at room temperature (25 C.) which forms the more disperse phase. The polymer fibre according to the invention possesses an improved dispersibility and is therefore suitable for producing aqueous suspensions which are used, for example, in the formation of textile fabrics, e.g. nonwovens.
