Abstract

The aim of the invention is to subject a non-woven, which consists, at least in part, of metal fibers, to a stitch-bonding or surface finishing by means of hydrodynamic needling. The respective material web can be produced exclusively from metal fibers but can also be produced from a blend consisting of metal fibers and textile fibers. The hydrodynamic water pressure during needling depends on the desired pore volume after stitch-bonding.

Can realize via following method according to this task of the present invention:
Realize high-tension or impulsive force by applying greater than the working medium pressure of 200 crust,
Use the geometry (combination of the different proportion of for example cylindrical, taper, biconial, cylindrical and taper) of specific nozzle,
The through-hole diameter of application examples such as 0.08-0.5mm,
Select the nozzle number of adjusting according to different uses for use according to the per inch working width,
At least utilize 2-8 root nozzle post,
Utilization is with the 1-4 row nozzle post of the capillary array of identical or different form,
With reinforcing medium from the both sides stress application, for example behind the one nozzle post of every interval or through behind a plurality of nozzle posts and carry out stress application,
Use a carrying band or to have the perforate cylinder of 20%-50% aperture area or have the 20-100 order, preferred 60 purposes are filtered the cloth that stretches tight and are discharged the reinforcing medium.
Utilize solution of the present invention, make that also can be provided thin by 100% metal fibre has closed or according to the hydro-entangled non-woven fabric of the through-hole surfaces of pattern, and can avoid following problem to take place:
The bearing fiber that need weave when it is produced,
Need take a lot of work and time-consuming yarn forming process,
In advance the generation of antistatic and guarantee fiber sliding properties good between fibre/fibre, fiber/reinforcement assembly and the fiber/supply unit and
Produce any wearing and tearing on the reinforcement assembly, because make water as reinforcing medium.
But, also can use nonmetal textile fiber material simultaneously and can not have problems from pure technical standpoint.What therefore belong to design of the present invention equally is under specific products characteristic demand, can use textile fabric with various mixed proportions.
Following embodiment elaborates this explanation.
