Definitions

  • Stretchable filaments are employed as starting material to form a web and various of the 28/722 D04h 18/00 filaments are then forced through the web surface and 28/4, 72.2; stretched in the process to form loops on one surface of the web.
  • Nonwoven materials having such a piled or looped appearance and soft feel.
  • a suitable support such as a cloth, felt, or paper, or a foam of plastic or rubber
  • continuous threads forming loops of which the tops can afterwards be cut and torn to produce hairlike fibers.
  • the thread is stitched through the support for example by machines called tufting machines. This thread is expensive however since it must be quite free from faults. Further, tufting machines have a relatively slow output rate.
  • discontinuous fibers providing a fibrous layer, by needling the fibers through the support.
  • These discontinuous fibers come out of the surface of the support in the form of tufts of pile and it is thus the fibrous web itself which produces them.
  • nonwoven needled cloths having a certain softness. It is even possible to separate,
  • the piled felts thus obtained are not very stable, however, because the fibers having free ends in a tuft of pile easily become detached from the needled web due to their short length. It is consequently necessary to subject this kind of article to a complementary treatment in order to reinforce the adherence of the tufts of fiber to their generating web.
  • the main object of the present invention is to provide a new type of product, constituted by a nonwoven fabric, having the appearance of a carpet or fur, which can be simply and rapidly made, and combines the qualities of good mechanical strength, good resistance to wear, an aesthetic appearance and soft feel.
  • a process for making a nonwoven fabric is characterized in that there is formed a web of synthetic substantially continuous filaments, incompletely stretched i.e., possessing a certain capacity for further permanent elongation, and very tangled, and in that some of the filaments of this web are driven through the web itself and at the same time stretched, to cause them to protrude in the form of loops from one of the faces of the web, the capacity for initial permanent elongation of the filaments being chosen according to the depth to which the filaments are to be driven and the number of loops which it is desired to produce over a given surface area.
  • Another aspect of the invention is the realization of a needling device for penetrating a textile web guided by a movable support, said device comprising a movable head furnished with needles and a corresponding supporting surface for the textile web provided with cavities opposite to the needles, characterized in that the needles have a shaft with a smooth surface and at least two terminal points separated by a recess.
  • a further aspect of the invention in the realization of a nonwoven fabric having the appearance of a carpet or a fur, composed of at least one web of tangled substantially continuous synthetic filaments, characterized in that the filaments of this web are orientated through the said web and form loops whose length is of the order of the thickness of the web, on at least one face of the latter.
  • FIG. 1 is a graph showing the curve of elongation against pull which can be obtained with a synthetic continuous filament
  • FIG. 2 schematically illustrates a thread drawing apparatus
  • FIGS. 3 and 4 show a needle according to the invention
  • FIGS. 5 and 6 diagrammatically illustrate two variants of the fabric obtained according to the invention.
  • FIGS. 7 and 8 diagrammatically illustrate two articles including a fabric made in accordance with the invention.
  • the needles When needling is carried out using barbed needles on any given web of fibers, the needles produce, in a direction perpendicular to this web, tufts of fibers on the face of the web from which protrude the needles as small lumps of fibers. There is obtained in this way a further considerable tangling of the fibers which constitute the base web, particularly on the face through which the needles enter which thus acquires a substantial cohesive strength.
  • the majority of fibers initially in the lower parts of the web are only slightly subjected to the action of the needles, and thus do not become as strongly intertangled as the fibers in the upper surface, of which a large part have been forced to penetrate through the mass of material.
  • the surface at which the needles enter is therefore generally much more solid than the exit surface which has often to be reinforced by impregnations of plastic materials.
  • the present invention it is proposed to drive filaments of a web of nonstretched, or more exactly incompletely stretched filaments, through this web, in such a manner as to avoid breaking of the filaments.
  • further stretchability of the thread driven in the form of loops through the web is utilized in order to avoid reaching the breaking point of the threads. The less the thread is stretched, the more the loop passing through the web can be elongated without breaking thereof.
  • Synthetic threads such as for example polyamide, polyester, or polypropilene, have the property, once solidified after the thread forming operation, of being capable of withstanding, without rupture but with a modification of their structure, considerable degree of permanent elongation.
  • This permanent elongation can be realized up to a limit which is more or less defined, beyond which the thread is said to be stretched and can hardly be elongated further and only elastically before breaking.
  • This stretched state well known by specialists, and which results in an orientation of the molecules of the product is in general sought and obtained industrially by an operation called drafting, because it is this which gives the thread its best mechanical characteristics.
  • FIG. 1 represents the elongation up to breaking point of a synthetic thread coming out of the spinneret as a function of the tension applied thereto.
  • the tension t is shown as the ordinate and the length l as the abscissa.
  • the part ab of the curve corresponds to the stretching phase proper, i.e. to the permanent deformation of the thread which is realized under practically constant tension.
  • the part be corresponds to an elastic deformation, a property which it is easy to check by slackening off the tension from the point b: it will be seen that the relation of deformation to tension is shown by the straight line b'B.
  • the part cd corresponds to a permanent deformation preceding the breaking point with destruction of the connections between the molecules, the diminution in cross section and breaking of the filament occun'ng at d.
  • the capacity for permanent elongation of the filament will be defined here by the ratio: AB/OB i.e. the ratio between the increase in length of the initial filament without tension and the length of the stretched filament without tension.
  • the determination of this capacity for permanent elongation is made easy by the presence of the elastic zone be; in effect, the pull exerted to effect stretching can be largely indeterminate provided it is situated in this zone.
  • the extend of the variation AB/OB depends essentially on the polymer and on the manner in which it is stretched.
  • nylon 6 for example, of relative viscosity 2, 8, this value can vary from 0.80 to as a function of the conditions existing when the filament was made.
  • incompletely stretched is meant the state of a filament of which the capacity for permanent elongation is other than zero.
  • Such a regulation can also be performed at the outlet if the spinnerets, where the filament is formed from melted polymer.
  • the threads are cooled, all the threads of a same spinneret being drawn at high speed by a takeup machine, or by a blowing nozzle fed by compressed air.
  • the drawing means are located at a considerable distance from the spinneret so that the threads do not stick together in the plastic state, and form what is called a multiple thread.
  • spinning ratio refers to the ratio between the driving speed of the thread and the speed of flow of liquid polymer though one of the holes of the spinneret.
  • drawing speed of the thread is always much greater than the flow speed of the liquid into a hole of the spinneret, and this results in a considerable narrowing of the thread while it is being drawn in the plastic state.
  • a thread stretching device is placed on the thread between the spinneret 1 and the drawing device 2 placed in a position where the threads 3 of the multiple filament 4 are still hot but no longer sticky, in such a manner as to perform the stretching under optimum conditions.
  • the capacity for permanent elongation can be varied by varying the speed of the stretching device, without changing the final denier value.
  • V/Vl of the winding speed to the speed of the pulley 7 of the stretching device there are obtained experimentally capacities for permanent elongation specified in the table hereunder:
  • the drawing device is a blowing nozzle
  • the capacity for permanent elongation to vary not only by means of deflecting rollers whose speed is maintained constant, but also by regulating the air pressure in the blowing tube in such a way that it produces an elongation of the thread between the entry and the exit of the said blowing nozzle
  • the speed of the thread at the exit of the blowing nozzle was in the region of 4.200 m./mn and the size of the thread discharged without tension about 3 deniers.
  • the capacity for permanent elongation of the threads of the multiple filament was 0.080.
  • these webs can be obtained from distributors of individual filaments or multiple filaments discharging the thread onto an endless receiving table which moves at a speed clearly less than that at which the thread arrived thereon.
  • Auxiliary devices for blowing air and for reciprocally driving the distributors transversally with respect to the receiving table enable the tangling of the threads to be increased.
  • This web lacks cohesion however, and in order to reinforce the latter, the web is caused to pass, at the exit of the table on which it is forced, into a well-known needle loom having barbed needles.
  • This needling being of relatively low density and low depth in order to avoid stretching the threads subjected to the action of the needles, is principally intended to facilitate the transport of the said web, or to enable it to be attached to one or more other webs according to requirements.
  • the presence of a-lubricant or pulverized preparation, at the entrance to the needle loom facilitates this operation.
  • an attractive effect is sought by' forcing loops of filaments through this web, without however neglecting to stretch the filaments of this web as completely as possible in order to obtain a finished product which benefits from the excellent mechanical characteristics of stretched filaments.
  • the web is subjected to a very deep needle penetration which causes the filaments of the web to be driven through the web itself, and at the same time stretches them.
  • the filaments fonn loops, which are all at the same height, and have substantially the same number of strands.
  • These needles can be placed in a known needle loom in a single row. in one embodiment, they have a diameter in the order of 3 mm. and their distance from axis to axis is in the order of 5 mm, this distance naturally being variable according to the effect which is desired.
  • the supporting plate of the needle loom that is to say the apertured plate on which rests the web and which serves to support it at the moment when the needles of the needling head penetrate it, can advantageously have, instead of holes opposite each needle, longitudinally disposed slots, in order to facilitate advancing the web.
  • the advancement of the web takes place in steps in a rhythm which is in step with the movement of the needles and at a rate which is controlled by a governing roller at the exit of the machine for the spacing of the rows of loops.
  • a governing roller at the exit of the machine for the spacing of the rows of loops.
  • the latter is of the same order as the distance between two neighboring loops of a same transversal row.
  • the needles were spaced apart two to the centimeter and the advancement of the machine is adjusted to 6 mm. at a time.
  • Another method of forming the loops consists in using a cylinder provided with needles according to the invention over the whole of its periphery, and to pass the web between this cylinder and a counter cylinder having circular channels opposite each row of needles.
  • This method has the advantage of providing a slow rate of penetration of the needles into the web, and of ensuring aprogressive and regular stretching of the filaments.
  • the loops Before commencing the operation of forming the loops, it is advantageous to heat the web to the optimal stretching temperature, which temperature depends upon the polymer.
  • the optimal stretching temperature which temperature depends upon the polymer.
  • the loops can be formed at a temperature of to C., and this greatly facilitates the operation of the machine, and provides fuller and more abundant loops, due to a diminution in the number of broken filaments.
  • This heating can be effected by infrared radiation or by passage of the web through a heating tunnel. in certain cases, the penetration of the needles is facilitated when a lubricating agent is sprayed onto the web since this favors slippingbetween the threads, and avoids thread breakages, as is well-known practice in the needling technique.
  • the web 11 thus treated has on one of its faces, thick loops 12 of vihich the height can be adjusted within a large range of values, and which can be clearly greater than 1 cm. (see FIG. 5).
  • the presence of a zone of elastic deformation after this zone of permanent deformation allows a certain latitude in the adjustment for this initial capacity for permanent elongation of the filaments, so that after penetration by the needles the threads are stretched or nearly so.
  • Loops having a height of mm. have also been made, from a web of 500 grams per square meter having filaments of which the capacity for permanent elongation AB/OB was 0.65. This web was passed into a needle loom having two rows of needles each row having one needle to the centimeter of width, these rows being spaced one from the other by 10 mm. The penetration of the needles was adjusted so that the lowest point of their movement was located at 25 mm. below the supporting surface of the web.
  • a capacity for initial permanent elongation and a needle penetration were chosen such that the filaments constituting the loops were pulled, by the penetration of the needles beyond their breaking point; breakage of the filaments at the top of the loops was thus provoked, and a carpet with the cut hairs or pile 14 having the appearance of a velvet was produced.
  • the filaments thus broken in the loops nevertheless remain very solidly gripped in the web 13 from which they project without any further treatment being necessary.
  • a pile carpet was made starting from a web of 300 grams per square meter, constituted by filaments having a capacity for permanent elongation AB/OB of 0.50.
  • the web was passed through a needle loom having three rows of needles, each row having two needles per centimeter of width, the rows being spaced from the other by 6 mm., and the penetration of the needles being adjusted so that the lowest point of their movement was located at 22 mm. below the supporting surface of the web.
  • the finished product had a pile of an average height of 8 mm.
  • the fabric is intended for heavy duty use, as for example in floor coverings, it is advantageous to reinforce it and to improve its dimensional stability with the aid of another web forming a reinforcement and formed with continuous filaments made in the same way as those of the fabric that is by previously being stretched with a ratio AB/OB in the vicinity of zero.
  • a carpet of this kind has been made by employing a web comprising continuous stretched filaments of nylon 66" of a weight per square meter of 300 grams, on which there was placed a web of continuous incompletely stretched filaments of nylon 66 of a weight per square meter of 550 grams, the two webs being slightly needled together and thereafter subjected to a needle penetration according to the invention, certain filaments of incompletely stretched thread being forced through the web of stretched thread.
  • the fabric made according to the invention can have numerous other applications either alone, or in composite form, in combination with other webs, or in the form of a coating.
  • it can be used for example for making wall coverings, blankets, household textiles such as fabrics for seats, or for curtains, clothing textiles for linings or overcoats, fabrics for slippers, and all other products having the appearance of a carpet or a fur.
  • a process for making a nonwoven fabric comprising the steps of: forming-a tangled web of synthetic continuous filaments which are incompletely stretched and therefore possess a certain capacity for permanent elongation; driving some of said filaments through said web so as. to form loops which protrude from a surface of said web, and at the same time stretching said filaments which are driven through said web, the capacity for initial pennanent elongation of said filaments being chosen according to the depth to which the filaments are to be driven and the number of loops which it is desired to form over a given surface area.
