Definitions
- the present invention relates to a method and a device for the heat treatment of flexible materials using a microwave application.
- the soft materials concerned may be fabric, thread, leather, cardboard, paper, etc.
- the treatments concerned may be the polymerization, in particular of textiles, scouring, bleaching, fixing of dyes, etc.
- a fabric set in motion by means of rollers is simultaneously subjected to microwaves in an enclosure.
- the use of microwaves is advantageous because the microwaves allow a short heating time.
- the process of treating the fabric is therefore shorter. It also makes it possible not to deteriorate the fibers.
- the inhomogeneity of the heating results from the installation of standing waves within the enclosure. The inhomogeneities may cause local defects on the fabric and overall, adversely affect the quality of the heat treatment.
- the invention overcomes the disadvantages presented above by allowing to obtain a high homogeneity of heating. It relates to a method of heat treatment of a flexible material comprising at least one step of circulation of the flexible material on a cylinder in rotational movement and heated from the inside, this step being simultaneous with a step of applying microwaves near the flexible material and opposite the surface of the cylinder.
- the invention makes it possible to activate the waves by setting these waves in motion.
- the cylinder is advantageously made of steel, a material that allows good reflection of the waves on its surface.
- the cylinder is coated with a layer of a material of the type known under the trademark Teflon whose function is the conductivity of microwaves. Teflon heat combined with that of the metal constituting the cylinder has the effect of attracting microwaves.
- a Teflon layer for example 3 to 5 mm thick, allows the waves to penetrate the fabric to the steel cylinder which reflects the waves. This allows the treatment of the fabric on both sides.
- the method is implemented in a chamber in a cylinder portion.
- the enclosure comprises a variable-speed rotating antenna intended to eliminate stationary microwaves inside the enclosure and thus to optimize the yields of the heat treatment of the flexible material.
- the use of a cylindrical or semi-cylindrical enclosure makes it possible to confine the waves which are present in a thin space between the cylinder and the wall of the semi-cylindrical enclosure.
- the circulation of the flexible material on the cylinder is guided by guiding means so that the material envelops the cylinder.
- the guides are for example small cylinders placed near the cylinder on which the flexible material flows.
- the step of applying microwaves is carried out using orientable microwave sources.
- the method comprises a preliminary step of heating the flexible material.
- This embodiment has the advantage of preparing the heating by microwaves which are more efficient from 60 0 C.
- a plurality of stages of circulation of the flexible material is performed on a plurality of cylinders in rotational movement and heated from the inside, steps performed simultaneously at a micro-application step. waves.
- the plurality of cylinders is heated to a plurality of temperatures so as to allow a flexible heat treatment of the flexible material.
- the heating of at least one cylinder and the characteristics of the movement of the cylinder are controlled by means of a computer program.
- the computer program can be stored on removable media.
- the invention also relates to a device for implementing the method described above as well as a computer program including instructions for implementing such a method. It follows from the technical characteristics described above a suppression of standing waves making homogeneous the microwave field inside the enclosure and therefore the heating of the flexible material. This heating homogeneity thus obtained makes it possible to optimize both the resistance of the flexible material and the fixing of the products on the flexible material, in particular the fixation of the dyes. Local defects on the tissues are thus avoided.
- FIG. 1 represents a device for implementing a method according to the invention.
- FIG. 2 represents a device for a particular embodiment of a method according to the invention.
- a device 100 for the heat treatment of a flexible material 101 comprises at least one cylinder 102 rotated about an axis 103 and heated from the inside.
- the cylinder 102 is set in motion by a thermo-regulated motor, the temperature taken on the materials being effected by means of infrared probes installed on the wall of the enclosure 102.
- the flexible material 101 flows.
- according to the invention comprises at least one microwave application module 104 placed near the cylinder. In FIG. 1, five microwave application modules 104 are shown. The role of these modules 104 is to apply microwaves to the flexible material 101 when it is circulating on the cylinder 102.
- microwave sources for example magnetrons of 800 watts, which are oriented towards the cylinder and can in this case be adjustable in order to obtain various kinds of treatment.
- orientable sources make it possible to determine the best position facing the cylinder 102.
- the microwave application is made close to the flexible material 101 and opposite the surface of the cylinder 102.
- the cylinder 102 has no magnetic properties.
- the invention when the invention is implemented to perform dyeing, it is useful for the cylinder 102 to have oxidation-reduction properties to prevent oxidation of the dye.
- the cylinder 102 is advantageously made of stainless steel.
- the heating makes it possible to reach temperatures of the order of at least 200 ° C.
- the cylindrical shape makes it possible to have a homogeneous distribution of the waves which are thus set in motion in a homogeneous manner.
- the movement of the cylinder 102 creates a dynamic within the microwave field.
- the heat and the movement of the cylinder make it possible to control the spatial distribution of the heat sources.
- the cylinder 102 is coated with a layer 105 of a material of a type known as Teflon.
- Teflon a material of a type known as Teflon.
- This material is conductive and transparent for microwaves: it thus allows the microwaves to pass through the fabric and the Teflon layer, are reflected on the cylinder, for example steel, and crosses the Teflon and the fabric.
- the fabric is treated on both sides.
- Teflon makes it possible to modify the angle of crossing of the microwaves and as the form is cylindrical this is all the more effective. Teflon thus plays the role of distributor and diffuser of microwaves in the tissue to be treated. It also has the advantage of having non-stick properties and not to oxidize. For example, when dyeing is carried out using the invention, this prevents the dye from sticking to the cylinder.
- the device 100 comprises an enclosure 107 in a cylinder portion, for example a cylindrical enclosure, in which the cylinder 102 is placed.
- the enclosure is for example made of stainless steel.
- this enclosure 107 which follows the shape of the cylinder 102 are shown five microwave application modules 104.
- the device 100 may include guides 108, for example, as shown in FIG. 1, two small guide rolls, for guiding the flow of the flexible material 101 over the roll 102 so that the flexible material 101 envelopes the roll 102.
- small guide rolls 108 are preferably covered with 'Teflon to prevent the reflected waves and the creation of a magnetic field with the main cylinder 102.
- the device includes computer means, not shown in the figure, for controlling the heating of at least one cylinder 102 and the characteristics of the movement of the cylinder 102 by means of a computer program.
- the computer program is stored on a removable medium, independent of computer resources.
- the flexible material is heated before passing into the chamber 107 and the cylinder 102. It can for example receive a spray and / or be passed through a heated bath and / or be passed in a pre-enclosure 106 comprising microwave sources 109 which heat the flexible material. These sources are for example magnetrons of 1200 watts. Thus it is possible to bring the flexible material to a temperature where the microwaves are known to be more active, namely around 60 0 C. According to a particular embodiment of the invention presented in FIG.
- the device 200 includes a plurality of cylinders 202, 212, 222, for example made of stainless steel, rotating about axes 203, 213, 223 and heated from the inside on which the flexible material 201 and a plurality of microwave application modules 204, 214, 224 circulate for applying microwaves to the flexible material 201 when it is circulating on the cylinders 202. , 212, 222.
