Definitions
- the present invention relates to an improvement made to false twist texturing techniques, and more particularly a new type of process able to be implemented on machines making it possible to treat wires partially or not drawn, at high speed, generally greater than 1000 m / min, the drawing of yarn being produced during the texturing operation.
- the technique most used these days is the technique called "simultaneous stretching-texturing" for which the stretching phase is performed on the twisted thread upstream of the false twist spindle, and this by simply adjusting the speeds between the two wire calling systems provided upstream of the oven and downstream of the false twist spindle.
- This technique poses implementation problems, in particular in the case of polyester yarns which are known to be under control perfectly the area where the necking point is located.
- the process according to the invention is characterized in that it localizes the necking point on the wire during the stretching phase causing a sudden break or change in the path of the wire during its ascent in temperature in the texturing zone, and this by pressing a surface or element allowing a rise in the reported torsion through the pin to the first call system.
- Such a break in the path of the wire makes it possible to locate the necking point can be achieved possibly by providing additional means for preheating and deflecting the path of the wire before entering the oven proper.
- the break trajectory is achieved inside the furnace by adapting said oven so that the change of trajectory takes place during its rise in wire temperature, preferably in the vicinity of the area where it inside the oven reaches its optimum processing temperature.
- Such a method is particularly suitable for being applied to so-called "high temperature” ovens which are increasingly offered on false twist texturing machines to reduce the length of the heat treatment area, such as those subject to US-A-5 193,293 (corresponding to EP-A-524,111).
- the type of oven covered by the patent aforementioned comprising a heating block proper, which comprises a succession of cylindrical zones having different diameters, arranged in line with each other, the wire to be treated being kept at a constant distance from the outside surface of small diameter areas so that the temperature rise of the wire is obtained in these radiation areas as it comes into contact with the surface of the areas of large diameter, the heat transmission then being carried out by contact, wire guiding elements being provided along the length of the oven to ensure its positioning.
- This type of oven implementing the method according to the invention is characterized in that it comprises, if one follows the trajectory of the wire, a entry area where heating is by radiation followed by a zone contact heating, at the outlet of which are arranged means allowing to modify the trajectory of the wire without however blocking the torsional rise, said trajectory then becoming regular again, straight or curvilinear, the wire then being subjected to a succession of thermal treatments by contact and by radiation until leaving the oven, the last zone being advantageously constituted by a zone of radiant heating.
- the intermediate zone between the entry zone and the exit zone is designed to allow, as said before, a combination radiant heating and contact heating, the length of different zones being adapted according to the wires to be treated.
- the zones of different diameters allowing to have such a combination of radiant heating and contact heating are performed in a similar to the teachings of European patent EP-A-578 589 (patent corresponding to US-A-5 332 882), whose design is such that the active element called "heating block” can be easily removed and reassembled, either to carry out maintenance operations such as the cleaning, or possibly to replace a heating block structure determined by a different block when you want to modify the heat treatment, for example when a wire must be treated different nature.
- the areas of different diameters allowing the combination of heating by radiation and contact heating consist of a plurality of elementary modules juxtaposed by fitting on the body of cylindrical heater which is fixed by one of its ends to the face removable from the hood of the oven, keeping said modules in position juxtaposed being provided by a positioning and blocking element itself secured to said removable face.
- the oven is advantageously designed to process two wires in parallel, guiding and positioning the wires inside the oven between the entry through eyelets provided on the face and the outlet through eyelets provided at the other end of the oven, being provided by guides distributed over the length of the heating assembly, thus allowing the path of the wires to be modified which can be either straight or preferably form one or two helices along the length of the oven between the inlet area and the outlet area where the path is straight.
- the location of the necking point is obtained in the entry area either during the temperature rise of the wire, or when it reaches approximately the normal temperature of treatment via a large diameter module on which the wire or wires are in contact and at the outlet of which they tie up, which can cause a sudden rupture or modification of the trajectory of said wire, area in which the necking point is located.
- this machine includes means which allow to modify the trajectory of the wire (2) during its rise in temperature in the texturing area, preferably inside even from the oven (4) in the vicinity of the zone where it reaches its temperature optimal treatment, while allowing torsional rise communicated by pin (6) until the first call (3).
- Such a rupture of the trajectory which makes it possible to locate the point of necking during the stretching phase, can possibly be carried out providing means for preheating and deflecting the path of the wire (2) before entering the oven (4).
- Such means will however preferably be integrated into the oven (4) himself.
- the oven will advantageously be of the type comprising a heating block (B) proper which comprises a succession of cylindrical zones (see Figure 2) having different diameters D and d arranged in the extension of each other.
- the wire (2) to be treated is kept at a constant distance from the sections of small diameter d, the rise in temperature being obtained in these radiation zones while in contact with the surface of D zones large diameter.
- Guiding means are provided along the length of the oven for ensure the positioning of the wire.
- the heating block (B) is designed, if one follows the path of the wire (2), so that it includes an area (10) radiant heating input followed by a first zone (11) of contact heating.
- a guide (12) is arranged which makes it possible to locate the necking point on the wire by modifying the trajectory, without however block the rise in torsion communicated by the spindle (6), said trajectory then becoming regular, straight or curvilinear as shown in Figure 2 to the exit of the oven with alternating contact and radiation heating zones.
- the last zone (13) of contact heating is followed by a zone (14) of radiant heating.
- FIGs 3, 4 and 5 illustrate in detail a furnace implementing the process according to the invention having the general structure of the type of that which is the subject of US-A-5,332,882 (EP-A 578,589).
- the oven makes it possible to process two wires (2) in parallel.
- the insulating block (21), made of refractory material, is advantageously of cylindrical in shape and has a recess, cylindrical in shape, intended to contain the heating element (B) which has a structure such as illustrated exploded in Figure 3.
- the heating element (B) is fixed by one of its ends to one of the end faces (16) of the cowling, this face being removable and supporting fittings (17) ensuring the electric supply of the oven and its regulation.
- the heating block (B) is designed so as to present a succession zones with different diameters D and d, so that the wires (2) are in contact with the large diameter zones D, the heat transmission then being carried out by conduction and are kept away from areas of smaller diameter d, the transmission of heat is then obtained by radiation.
- the guidance and positioning of the wires (2) inside the oven between the entry through the eyelets (18) provided on the face (16) and the exit at through eyelets (19) provided at the other end of the oven, is provided by through guides (30,31,32). These guides are spread over the length of the heating assembly and allow the path of the wires so that it is for example rectilinear over part of the length of the oven, in this case in the entry area (10) and in the exit (14), then helically in one or more successive zones, in the case present in the two middle zones.
- the abrupt change in the trajectory of the wire to the interior of the oven is obtained by associating with the first module (11) of diameter D the first guide element (30) which is designed so to wire the wire on the edge (11a) of the module (11) and which therefore serves as guide (12), thus making it possible to locate the point of necking in this zoned.
- the length of the wire contact area on this first module (11) may be variable depending on the nature of the wires and will generally be in the range of 2 to 10 cm.
- the heating element (B) is designed as as shown schematically in Figure 3, and consists essentially a cylindrical heating body (15), shown in dotted lines, comprising one or more resistors embedded in a matrix and obtained by molding.
- This heater also has an element thermocouple allowing precise regulation of the temperature.
- the resistances can be designed in different ways, for example to have a constant temperature over the entire length of the oven or to have variable temperatures, in which case we could, for example, have in parallel two resistors which can either be of the same length or be offset from each other along the length of the oven.
- elementary modules are used whose length can be adapted according to the treatments to be carried out, which can be slid onto the heating body (10), and which constitute cylindrical surfaces of different diameter D and d.
- Each module can either alone form a small diameter area d, either a large diameter area D, or possibly combine a alternation of large diameter zones D and small diameter zones d as shown in figure 3.
- each module corresponds to the diameter external of the heating resistor (15) so that the modules can be fitted by simple sliding around the latter.
- Maintaining the position of the various modules and guides around the heating body (10), is produced by any suitable means, for example by means of a locking ring or by means of screws, the different modules being locked longitudinally via a tie rod (17) integral with the entry face (6), and the end (33) of which comes snap into a notch (34) provided in the outlet guide (32).
- radiation The positioning of the first module (11) relative to the oven inlet is adjusted by means of a spacer (35) appropriate length to define an entry area (10) where carried out radiation heating which may have a suitable length as needed.
- Such a type of oven makes it possible to carry out a drawing operation texturing of all types of synthetic yarn including polyester yarn, wire neck point being perfectly located during the phase stretching.
- This machine is equipped with a 100 cm high temperature oven in length, having a structure as shown schematically in Figure 2 and which has an entry area (10) for radiant heating having a length of 20 cm followed by an area (11) with a diameter of diameter D of contact heating of 2 cm.
- the path of the wire (2) is deflected by the guide (30), which therefore results in an embarrassment with said surface (11) making it possible to locate the point of necking.
- Downstream of the deflection guide (30) are arranged in a succession of zones of diameter D and of diameter d, having a length of 1.2 cm and 5.5 cm respectively, the path of the wire being regular, straight or curvilinear until taken out of the oven.
- the last zone (13) of diameter D is followed by a zone (14) of diameter d having a length of 16 cm where radiant heating takes place.
- the heating element embedded inside the block, element not shown in Figure 2 attached, is brought to a temperature of 600 ° C.
- the oven is followed by a cooling zone (5) of length 1.25 meters and a false friction spindle with external friction (6) rotating at a speed of 11,000 rpm, comprising discs in ceramic.
- the speed of the output deliverer (7) is set to 1000 m / min, allowing a stretch of 1.73.
- a conventional fixing oven is arranged, not shown in Figure 1, having a length of 1.20 m and brought to a temperature of 200 ° C.
- the winding speed is 980 m / min.
- the machine according to the invention allows, in production industrial, to eliminate the presence of broken strands and allows to obtain a very homogeneous production between the different positions of processing from one machine to another.
