Description
Fil artificiel,
Les fils artificiels actuellement connus, qu'il s'agisse des produits préparés par voie chimique dans l'industrie de la rayonne on de la laine cellulosique et dans les industries ana-
<EMI ID=1.1>
physique, présentent l'inconvénient grave pour la mise en oeuvre textile par filature, etc."., d'avoir tendance à s'allonger, alom qu'il serait souhaitable en soi, à ce point de vue, que les fils aient une forme ondulée. De nombreux essais et de nombreuses propositions ont déjà été étudiés à la suite de la constatation de cet inconvénient pour obtenir une ondulation ou un crêpage des file. Or, tous ces procédés connus sont difficiles à réaliser et ne fournissent pas de solution satisfaisante du problème.
A cet égard, la présente invention permet, au cours de la
<EMI ID=2.1>
pé à n'importe quel degré désiré.
L'invention consiste en ce que le fil coiporte une cavité continue d'une excentricité qui change au fur et à mesure qu'on se déplace le long du fil. On a observé que, par un fait surprenant, on peut obtenir par ce moyen à n'importe quel degré désiré et par variation de l'intervalle de temps dans lequel se produit le changement du sens de l'excentricité, une ondulation ou un crêpage réglables du fil. A ce propos, on peut assurer le changement, périodique de préférence, de l'excentricité soit en quelque sorte suivant un mouvement pendulaire.ou oscillatoire, c'està-dire passer d'une déviation dans un sens donné immédiatement
à une déviation dans le sens opposé, et produire par ce moyen des ondulations de même sens, soit obtenir une allure continue pour les ondulations, en faisant varier- l'excentricité d'une manière, continue suivant une courbe.
Artificial yarn,
Artificial yarns currently known, whether they are products prepared by chemical means in the rayon or cellulosic wool industry and in the ana-

physical, have the serious drawback for the textile processing by spinning, etc. "., of having a tendency to elongate, although it would be desirable in itself, from this point of view, for the threads to have a corrugated form. Numerous tests and numerous proposals have already been studied following the observation of this drawback for obtaining corrugation or creping of the strands. However, all these known methods are difficult to carry out and do not provide a satisfactory solution. of the problem.
In this regard, the present invention allows, during the
<EMI ID = 2.1>
pe to any desired degree.
The invention consists in that the wire carries a continuous cavity of an eccentricity which changes as one moves along the wire. It has been observed that, surprisingly, it is possible to obtain by this means at any desired degree and by variation of the time interval in which the change of the direction of the eccentricity occurs, waviness or crimping. adjustable thread. In this regard, it is possible to ensure the change, preferably periodic, of the eccentricity either in a sort of pendular or oscillatory movement, that is to say to pass from a deviation in a given direction immediately
to a deviation in the opposite direction, and thereby produce undulations in the same direction, or obtain a continuous shape for the undulations, by varying the eccentricity in a continuous manner along a curve.
