The invention relates to a high-strength light-weight non-woven fabric made of spunbonded non-woven, particularly for use as a reinforcement or strengthening material, comprising at least one ply of melt-spun synthetic filaments, which are bonded by means of high-energy water jets, characterized in that it includes a thermally activatable binding agent, which is applied onto the ply of melt-spun filaments in the form of at least one thin layer. The invention further relates to a method for producing such a non-woven fabric.

High-strength lightweight non-woven fabric made of spunbonded non-woven, method for the production thereof and use thereof

The invention describes a velour needle-punched nonwoven material, which is produced by placing an optionally pre-strengthened nonwoven material on a brush-like stitch base and needling of the nonwoven on this stitch base. The velour needle-punched nonwoven material according to the invention is characterized in that the nonwoven material comprises a spun-bound nonwoven with filaments, wherein the filaments comprise multicomponent filaments with at least one component with a high melting point and at least one thermally activatable component with a low melting point. The velour needle-punched nonwoven material according to the invention not only has excellent mechanical properties, it is also particularly compatible with the environment and health and therefore suited for applications as a textile lining not only in the private field, but particularly in the public domain.

Velour needle-punched nonwoven material and use thereof

The object of the invention is to provide a method which is as simple and economical as possible for manufacturing a tufted product, in particular a tufted top layer of a carpet, having improved nep adhesion properties. For this purpose splittable fibers are used which split on or in the region of the puncture site during tufting.

Method for manufacturing a tufted product, tufted product, and use thereof

A tufted backing and a method of manufacturing a tufted backing from thermoplastic polymer fibers or filaments that are processed to yield a spunbonded nonwoven are described, the spunbonded nonwoven containing only fibers or filaments having a titer of 1 to 15 dtex, the mass per unit area of the tufted backing being 70 to 110 g/m, its density being 0.18 to 0.28 g/cmand the 5% modulus value in the machine direction being &#x3e;60 N/5 cm, but at least 0.6 Nm/g.

Spun nonwoven fabric and apparatus for the manufacture thereof

The apparatus for manufacturing the nonwoven fabric contains at least one, and may contain up to forty or more, spinneret devices, such as rectangular spinneret plates or round spinneret disks. The spinneret devices may be arranged in rows or in staggered arrangement above a linearly moving collector belt. Spinning orifices on the spinneret devices are respectively dedicated to producing a monofilament or a bicomponent filament from a melt and, viewed in the direction of motion of the collector belt, are arranged with respect to one another so as to correspond in their totality to the cross sectional structure of different filament types in the nonwoven fabric.

Apparatus for the manufacture of a spun nonwoven fabric

A textile composite material is used as tuft backing for tufted carpets, the composite material having at least one nonwoven fabric on which exclusively parallel-running, straight, load-absorbing, plastic, continuous filaments are rascheled, and a thin binding yarn serving as a knitting chain fixing the continuous filaments in position.

Tuft backing

A spunbonded fabric comprises continuous thermoplastic filaments, which adhere to one another at their intersecting points without binder, and whose material comprises at least 50 weight % biodegradable polycaprolactone having a mean molecular weight of from 35,000 to 70,000. In the production process of the spunbonded fabric, no additional stabilization step is necessary after the filaments are deposited.
