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.

Textile compositions comprising at least one filamentous fungus are disclosed, as are methods for making and using such textile compositions. Embodiments of the textile compositions generally include at least one of a plasticizer, a polymer, and a crosslinker, in addition to the filamentous fungus. The disclosed textile compositions are particularly useful as analogs or substitutes for conventional textile compositions, including but not limited to leather.

A polymeric material that includes a thermoplastic composition containing a continuous phase that includes a matrix polymer and a siloxane component is provided. The siloxane component contains an ultrahigh molecular weight siloxane polymer that is dispersed within the continuous phase in the form of discrete domains. A porous network is defined within the thermoplastic composition that includes a plurality of nanopores.

Provided is a fiber web for a gas sensor. In one exemplary embodiment of the present invention, there is provided a fiber web for a gas sensor including nanofibers including a fiber-forming material and a sensing material for reacting with a target substance in a test gas. According to the exemplary embodiment, the fiber web for a gas sensor is capable of identifying the presence or absence of a target substance in a test gas and quantitatively determining the concentration of a target substance, and exhibits improved sensitivity due to having an increased area of contact and reaction with a target substance contained in a test gas. In addition, the fiber web for a gas sensor facilitates the detection of a target substance in a test gas at a low cost and thus can be widely used for the detection of various volatile organic compounds (VOCs) in households, the diagnosis of asthma or esophagitis or the identification of a patient suffering from the same, and the detection of hazardous materials in other fields of industrial safety.

Methods for characterizing a nanotube formulation with respect to one or more particular ionic species are disclosed. Within the methods of the present disclosure, this characterization provides control over the surface roughness (or smoothness) and the degree of rafting within a nanotube fabric formed from such a nanotube formulation. In one aspect, the present disclosure provides a nanotube formulation roughness curve (and methods for generating such a curve) that can be used to select a utilizable range of ionic species concentration levels that will provide a nanotube fabric with a desired surface roughness (or smoothness) and degree of rafting. In some aspects of the present disclosure, such a nanotube formulation roughness curve can be used adjust nanotube formulation prior to a nanotube formulation deposition process to provide nanotube fabrics that are relatively smooth with a low degree of rafting.

A method for forming a fiber is provided. The method comprises extruding a matrix polymer and a nanoinclusion additive to form a thermoplastic composition in which the nanoinclusion additive is dispersed within a continuous phase of the matrix polymer. The extruded thermoplastic composition is thereafter passed through a spinneret to form a fiber having a porous network containing a plurality of nanopores, wherein the average percent volume occupied by the nanopores within a given unit volume of the fiber is from about 3% to about 15% per cm.sup.3.
