Abstract

A method for the uniform bonding of a nonwoven is disclosed which comprises cut fibres and/or filaments such as also synthetic fibres are continuously laid immediately previously, possibly mixed with natural fibres such as also pulp, formed for example by a carder or by the air laying method and/or by means of the spun bond method and are then intertwined by means of hydrodynamic needle punching, wherein the nonwoven is exposed to a row of water jet bonding treatments on one or both sides, wherein before, during and/or after a first hydrodynamic needle-punching and/or a subsequent hydrodynamic needle-punching over the width, the nonwoven at least partially undergoes a forced re-orientation of the fibres and the nonwoven is then subjected to a further water jet treatment. Also an installation for said method is disclosed, wherein a device for water needle punching is combined with a following stretching device which strains the prebonded nonwoven uniformly over the width.

Basically, the fibers extend in the longitudinal direction of the wool to produce a slight amount of strength in the transverse direction after, for example, a hydrodynamic weaving process. SUMMARY OF THE INVENTION The main object of the present invention is to invent a method for obtaining a uniform hardened wool on a plane formed in both directions of MD and CD, and thereby obtaining an overall hardened wool. The solution to this task can be ascertained by the fact that the wool is before a first hydrodynamic weaving procedure, during and/or after processing, and/or immediately after a particularly hydrodynamic weaving procedure. At least the entire fiber should be re-twisted over its entire width, and then the wool is subjected to further water jet treatment. The fiber re-orientation operation can be produced by lateral spreading, by means of a press and/or only a surface treatment such as a brush, or by lateral tilting misalignment, or by changing the direction of the water jet. method. Thereby, the wool as a whole can obtain a higher strength than that which the unreoriented fibers can achieve. This processing method can also be performed one by one. At this point it can be noted that the wool is evenly spread over the entire width, for example, when the wool is supported by a spreader, a brush or a full plane of the press, whichever happens, and which acts on the wool The force is intruded evenly across the width of the wool. Such devices are well known in the textile arts for the treatment of woven and knitted fabrics.
