A piezoresistive force sensor which is designed in particular as a pressure sensor and can generate a sensor signal which is dependent on an amount of a force which acts on the force sensor in a force measuring direction. The force sensor has a first electrode, a second electrode and an elastically deformable resistance layer which electrically connects the two electrodes. A resistance value of a total resistance of an electrically conductive path between the first electrode to the second electrode via the resistance layer changes according to the amount of the acting force. By measuring a voltage between the electrodes or a current which flows along the electrically conductive path, for example, a sensor signal can be detected which describes the amount of the acting force. The resistance layer contains electrically conductive first staple fibers and electrically non-conductive second staple fibers. A proportion of the first staple fibers relative to the total quantity of staple fibers can be varied in order to adapt the force-resistance characteristic of the force sensor to the particular task.

A description is given of a composite material with a matrix on the basis of an organic plastic containing solid fillers. This composite material is distinguished by the fact that the filler is a dried fermentation residue from the fermentation of vegetable substrates. This composite material opens up beneficial uses, such as in the construction of furniture and exhibition stands and for decorative articles and products relating to gardening and landscaping. The invention therefore avoids the discarding of fermentation residues from the fermentation of vegetable substrates. Instead, they are advantageously used in composite materials. This is therefore a very useful way of making use of such materials, it having been found that the physical properties of the composite materials provided with a dried fermentation residue are sufficient for the respectively intended applications.

The present invention relates to a method for the continuous production of high-strength endless filament yarns with a compact, especially homogeneous structural morphology based on polyacrylonitrile for carbon fibre precursors, which are produced on the basis of this method, and relates to carbon fibres that can be obtained by carbonization of the carbon fibre precursors. The fibres are formed from polymer solutions in ionic fluids as part of a wet or dry-wet process. In the production of yarns and filaments, there is a further stretching of the freshly formed elements immediately after precipitation in an organic solvent or a diluted aqueous solution of the respective ionic fluid or in a saturation vapour zone. The precursor yarns and filaments obtained primarily have an increased tear resistance with simultaneously sufficient elongation, a round cross-section and a compact, especially homogeneous fibre morphology and are particularly well-suited for further processing and production of high-strength carbon fibres for technical applications in composite materials. Carbon fibres produced in this manner are also characterized by a tensile strength in the range of 3.0 to 8.5 GPa, an elongation at rupture in the range of 0.5 to 3.0%, a modulus of elasticity between 100 and 600 MPa, and a titer of 0.1 to 3.0 dtex.

A process is described for producing surface-modified polypropylene filament yarns that are dyeable from aqueous liquors. This process is characterized in that the filament yarns, comprising standard commercial PP, in the course of their formation in a melt spinning procedure, undergo treatment with a hydrogen peroxide solution. The invention further relates to polyolefin filament yarns obtainable by this process, and to the use of these polyolefin filament yarns for producing sheetlike textile structures, with the possibility of advantageous subsequent dyeing with vat dyes. The treatment referred to or the upgrading step, which in accordance with the prior art normally takes place at a much later point in the production chain, therefore yields a hydrophilized filament yarn without an additional downstream treatment step, such as by plasma treatment, for example, and also without any other additional energy input. The resulting filament yarn can be processed and upgraded in the same way as has hitherto been the case in the industrial practice. Without the aftertreatment of the prior art, the textiles obtained in accordance with the invention exhibit a desirable dyeability. This can be achieved without further pretreatment, by means of vat dyeing by the Thermosol process in deep shades, and the vat dyeing at the same time possesses the high light fastness known for vat dyeings.

Nanoscalar primary particles based on SiO2 or a mixed oxide of SiO2 and other metal oxides, in particular Al2O3, are disclosed. These particles have an average particle size ranging from 1 to 2000 nm (determined by the particle size measuring method that uses a Zetasizer NS (Nano Series)) and a negative charge, and can be advantageously used for producing a hydrophilic coating on textile materials. If required, a hydrophobic outer layer can be formed on the previously treated hydrophilic material, ensuring an enhanced alcohol and oil repelling effect, in comparison with a textile material without a hydrophilic intermediate layer. The nanoscalar primary particles can be used for this purpose in a particularly advantageous manner if they are added to the reaction solution in statu nascendi.

The invention relates to a polyester based on a polycondensation product of terephthalic acid and/or terephthalic acid derivatives comprising bivalent alcohols. Said polyester is characterised in that (I) between 40 and less than 90 mol. % of ethylene glycol, propane-1,3-diol and/or butane-1,4-diol is combined with (II) between 60 and more than 10 mol. % alkane-l,2-diol, exclusively ethylene glycol, and the polyester has a melting point of between approximately 145 and 250 °C (in accordance with DIN EN ISO 53765). It has a comparatively low melting point, such that it can be retreated at the lower melting temperature. This prevents undesired secondary and decomposition reactions during the retreatment, and enables energy costs to be reduced. The inventive polyester is especially suitable for producing fibres or filaments by melt-spinning, and films, bottles and other moulded parts according to an injection moulding method. The fibres can be treated to form a high-quality nonwoven material.
