Abstract: The invention relates to a melt-blow head with a rectilinear row of nozzle bores arranged in a nozzle bar, said nozzle bores serving to produce endless filaments formed from a melt, said nozzle bores being associated with blowing slots, in the form of longitudinal slots, of two slot-plates for feeding blowing air at an angle to the nozzle bores and to which nozzle bores the melt is fed through one or more distributors in the melt-blow head, the distributor(s) being supplied with the melt through a feeding pipe. The feeding pipe in the melt-blow head leads from a lateral inlet via a redirecting means in an essentially vertical direction to the distributor, said inlet being connected to a melt pipe through a removable connector, the nozzle bar being fixed in a defined position with respect to the slot-plates and being removable therefrom in an approximately vertical direction.

Abstract: A process is disclosed for the manufacture of a spunbonded fabric consisting of thermobonded curled bicomponent fibers where the bicomponent fibers consist of two plastic materials with different properties.

In a second step the fibers are placed on a sieve belt and thermobonded. In a third step the bicomponent fibers of the obtained nonwoven fabric are finally curled by lengthwise and/or transverse stretching and heat treatment.

Abstract: The invention relates to a method for producing a spunbonded fabric from thermobonded crimped bicomponent fibers.
