OBTAINED
Field of the Invention This invention relates to a process for obtaining special effects on vertical needled nonwoven fabrics as well as the needled fabrics obtained.
Background of the Invention Nonwoven fabrics consolidated by traditional needling and on which a velour or looped appearance has been obtained by the action of special fork needles have been used for years for making floor coverings, and then wall coverings.
An effort has already been made to modify the appearance of this type of needled fabric, called vertical needled, fabric by making the penetration of the looping needles vary; thus it is possible to obtain loops of different height as a function on the pattern to be obtained.
It is quite obvious that this type of effect should be provided during the production of the vertical needled fabric.
The applicant had the aim of developing a process for obtaining special effects and particularly structured effects on this type of vertical needled Signature. LECL.ERC. I To: THE COMMISSIONER OF PATENTS. S BMWE R S.
aeu Captal de 346.718.
0 'onr, 4, Rue Benjamin. Corst Melbourne. 4' Rue Benj 92521 f NEUILLY-SUR-SEINE CEDEX 2 fabric, a process that could be used as late as possible in the production line, particularly to allow a differentiation of product just before its delivery to thr retailers.
The embossing techniques seemed especially advantageous for this purpose.
It is known that standard embossing processes consist in making the support or layer to which it is desired to impart the structure effects pass between a cylinder engraved according to the pattern it is desired to obtain and a smooth countercylinder. In the increasingly frequent case where the support comprises a considerable proportion of fibers or thermoplastic yarns, the engraved cylinder is brought to a temperature close to the softening point of these fibers or yarns, and the combined action of heat and pressure, joined to the depth of the engraving, give the support the desired permanent structure effect.
When the support it is desired to engrave is .an article exhibiting relatively great pile heights (about 3 mm), as is the case of vertical needled fabrics, it seems essential to achieve advantageous and permanent structure effects to use embossing cylinders whose engraving depth corresponds essentially V to the height of the piles.
I Now, the applicant was able to determine that the use of engraving cylinders of this type had numerous drawbacks of which there can be cited the high engraving II cost and especially the "plasticized" appearance that they give to the vertical needled fabric; the latter loses practically all textile appearance that is so desired in the field of mural coverings.
Summary of the Invention It has now been determined, in a surprising way, that it was possible to obtain very advantageous 200 3 structured effects on a vertical needled fabric without impairing its appearance and its feel, by acting on two important factors: the depth of the engraving, the temperature of the embossing cylinder and the countercylinder.
The process for obtaining special effects on a vertical needled fabric is characterized in that it consists in subjecting the looped face of the needled fabric to the action of a embossing cylinder whose engraving depth is less than the height of the loops of the needled fabric, the embossing cylinder being brought to a temperature markedly less than the softening temperature of the thermoplastic fibers of the needled fabric, and the countercylinder also being heated.
Thus, it is possible to obtain an entire series of extremely advantageous effects without thereby altering the feel of the needled fabric and without causing plastification of the fibers.
Brief Description of the Drawings This invention will be better understood and its advantages will come out from the following description of an embodiment of the process according to the invention with reference to the accompanying diagrammatic drawing in which: Figure 1 is a diagrammatic section of a vertical needled fabric subjected to the process according to the invention; Figure 2 is a diagram of the apparatus used for using the process.
In the drawings, the vertical needled fabric is designated in a general way by 2, the engraved cylinder by 3 and the countercylinder by 4.
The apparatus used for using the process according to the invention and represented very diagrammatically in figure 2 comprises essentially a

i0, Detailed Description of the Invention The process for obtaining special effects on a vertical needled fabric according to the invention will now be described in detail, by way of nonlimiting example.
First, a layer of polypropylene fibers of fine
II
denier (from 3 to 6 decitex) is prepa-ed which is subjected, in a standard way and on an apparatus not o shown, to the successive operations of carding, consolidation by flat needling and looping by special needles. Thus, vertical needled fabric 2 exhibiting loops or piles 5a about 3 mm high is obtained.
Then, this needled fabric 2 is continuously made to pass over a smooth calender 9 which assures S- o gluing to back 4 of needled fabric 2 of paper support 8 iL 2 5, coming from roller 7. A glue application means (not Srepresented in the drawing) is provided before reaching I calender 9.
i The unit of needled fabric 2 and paper 8 is then subjected to a hot embossing process by passage between engraved cylinder 3, acting on piles 5a, and countercylinder 4.
The engraving of embossing cylinder 3 is selected so that its depth in all cases is less than the height of piles 5a of vertical needled fabric 2. In this case, the depth of this engraving is 1 to 2 mm depending on the effect it is desired to obtain.
Embossing cylinder 3 is brought a temperature between 120 and 140°C, a temperature markedly below the softening temperature (170°C) of the polypropylene fibers; the countercylinder is brought to a temperature of about 160°C and the embossing action is performed at a pressure of about 40 bars.
After passage in the embossing device, vertical needled fabric 2 exhibits the appearance diagrammed in figure 1 where it is quite clear that the part of piles 5b subjected to the embossing action is a not completely crushed; therefore the article retains its appearance and textile feel without plastification being observed as would be the case if the softening temperature of the thermoplastic fiber were reached, or i if the operation were performed with such engraving depths that piles 5a are crushed over their entire height.
It is quite evident that by acting on the engraving design given to engraving cylinder 3, it is Q possible to obtain a quite advantageous effect engraving; also special effects can be obtained by prior dyeing or printing of vertical needled fabric 2.
The foregoing description of the specific embodiments will so fully reveal the general nature of 195 the invention that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments without departing from the generic concept, and therefore such adaptations and modifications are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments. It is to be understood that the phraseology or terminology herein is for the purpose of description and not of limitation.
