Definitions

  • the present invention relates to the field of fusible linings which are supports, textile or non-woven, on one side of which are applied points of hot-melt polymer, likely to adhere later on the piece of clothing to be reinforced under the effect of the application of a certain hot pressure. It concerns more particularly a process for manufacturing such a covering, is carrying out an electronic bombardment in order to locally modify the melting point and / or viscosity of the hot-melt polymer; she also relates to a fusible interlining obtained by said process whose hot melt polymer dots have a melting temperature or their viscosity differentiated in their thickness.
  • this piercing has for effect of locally increasing the stiffness of the interlining and therefore of the part of clothing, which may be contrary to the desired effect. cause bonding on lining fabrics such as lining and lapels of drapery, which causes degradation of the quality of the garment.
  • the applicant has already proposed, in the document FR 2 606 603 to implement means of a nature chemical, acting on the hot-melt polymer in order to modify its chemical structure, at least partially, at least at the interface with the interlining support, so as to prevent the hot-melt polymer from stick through the interlining under the effect of heat and / or pressure and / or steam.
  • the means, chemical in nature, suitable for modify the chemical structure of the hot-melt polymer at least one reactive material and at least one reactive means capable of initiating, ensure, promote the reaction between the reactive material and the polymer hot melt.
  • the reactive means the heat inputs, the ultraviolet radiation, electronic bombardment. It is stipulated that this reactive means can be used in the presence of catalysts. More precisely when the reactive means of the crosslinking reaction of the hot melt polymer and modified vinyl reactive polymer is UV radiation, it is expected that this will occur with contact of photo-initiator products.
  • the goal set by the applicant is to propose a method of manufacture of a fusible interlining using a electron bombardment to modify the chemical structure of the polymer hot-melt which overcomes the aforementioned difficulties.
  • a stabilizer support chosen from textile supports and non-woven, dots of hot melt polymers of medium thickness E and one of the faces of said support is subjected to bombardment electronic.
  • the points of hot-melt polymers containing a radical activator and being free of photo-inhibitor
  • the depth of penetration of the electrons in the points of the hot-melt polymer is adjusted to obtain a modification of the physicochemical properties of the hot-melt polymer, chosen from the melting temperature and the viscosity, over a thickness e with respect to the average thickness E.
  • the function of the radical activator is to create free radicals allowing to initiate the polymerization reaction on itself of the polymer hot melt. It is akin to the photo-initiating agent provided for in the document FR 2 606 603 during the implementation of UV irradiation as a reactive medium. The radical activator is therefore not properly speak of a reactive substance in the sense provided for in document FR 2 606 603.
  • this radical activator is of the acrylic type, in particular trimethylol propane trimethacrylate or trimethylol propane triacrylate.
  • acrylic-functional monomers are acrylic-functional monomers and are not part of the explicitly provided list, for the subject reactive, in document FR 2 606 603.
  • the reverse side of the interlining support is subjected to electronic bombardment and the penetration depth of the electrons is adjusted to obtain the modification of the physicochemical properties over a thickness e of between 10 and 50% of l 'average thickness E , the modification consisting in an increase in the melting temperature or in an increase in the viscosity of the hot-melt polymer.
  • the face side of the interlining support is subjected to electronic bombardment and the depth of penetration of the electrons is adjusted to obtain a modification of physicochemical properties over a limited thickness of between 50 and 90% of l 'average thickness E , the modification consisting in a decrease in the melting temperature or a decrease in the viscosity of the hot-melt polymer.
  • each point of polymer happens to be made by a single deposit, monolayer, and after the bombardment action electronic, said layer has a melting temperature and / or a differentiated viscosity between a first lower zone which is in contact with the textile support and which has a melting temperature and / or a given viscosity and a second upper zone which has a temperature of melt or a viscosity lower than that of the hot-melt polymer of the first zone.
  • the electron beam generated by the cannons at industrial electrons does not have a uniform action in the thickness of a given material.
  • the quantity of electrons or dose decreases as and thickness measurement, until it becomes zero at a given thickness, which is a function of the acceleration voltage of the electron beam.
  • the electron dose is canceled for a thickness of 200 ⁇ m, through a material of density 1. This dose is still around 50%, in this case, for a thickness of around 130 ⁇ m.
  • the applicant has found that in order to obtain a modification of the physicochemical properties of the hot-melt polymer which is such that the lower layer of the point can play the desired barrier effect, avoiding the piercing of the fusible interlining, it was necessary for it there is a certain dose of electrons which has reached the radical activator.
  • the adjustment of the depth of penetration of the electrons therefore aims to ensure that there is this sufficient dose of electrons which could have penetrated into the limited thickness e of the hot-melt polymer, that is to say the thickness for which the modification of physicochemical properties is sought.
  • the depth of penetration of the electron beam into the polymer points hot melt by interposing a filter between the electron beam and the stabilizer support.
  • This filter has the effect of artificially reducing the thickness of penetration of the electron beam into the hot-melt polymer and therefore fine-tune the really effective penetration depth
  • filter which can in particular be a sheet of paper and, in particular its thickness, depends on the material constituting the stabilizing support and on the thickness e for which a modification of the physicochemical properties is desired.
  • the operating conditions of the bombardment electronics as well as the choice and quantity of radical activator are determined so that the melting point of the polymer hot-melt has a variation, more or less of the order of 10 to 20 ° C in the area subject to electronic bombardment.
  • a fusible interlining 1 consists of a support 2 and points 3 of thermofusible and fusible polymer.
  • the support can be either a textile support proper, of the woven, knitted or knitted type weft insertion, a nonwoven.
  • 3 points of polymer hot-melt are arranged on all or part of the surface of one of the two faces of the support 2, called the face side. It is this face that is intended to be applied against the reverse side of the piece of clothing to protect or strengthen.
  • the hot-melt polymer is a known type, among polyamides, polyethylenes, polyurethanes, polyesters, aminoplasts ... This can also be a copolymer. The important thing is that the polymer in question can, at the temperature of application of the piece of clothing under hot pressure, react by locally melting to adhere to the fibers or filaments on the reverse side of the piece of clothing.
  • the polymer dots are deposited in the form of an aqueous dispersion which is then subjected to a heat treatment so as to evaporate the solvent and agglomerate new hot melt polymer particles to achieve their hanging on the support.
  • the polymer points are deposited by any conventional technique, in particular printing with a rotary frame or other.
  • the polymer points on the surface of the interlining support represent of the order of 5 to 20 g / m 2 , depending on the type of support.
  • the aqueous dispersion of hot-melt polymer comprises also a radical activator, i.e. a compound which is capable of form free radicals under the effect of electronic bombardment, and is free of photo-inhibiting agent.
  • a radical activator i.e. a compound which is capable of form free radicals under the effect of electronic bombardment, and is free of photo-inhibiting agent.
  • an activator of the acrylic type such as trimethylol propane trimethacrylate or else trimethylol propane triacrylate.
  • the proportion of radical activator can be between 5 and 20% by weight relative to the hot-melt polymer.
  • aqueous dispersion of hot-melt polymer after having carried out the deposition of the aqueous dispersion of hot-melt polymer and then the heat treatment of the latter in order to evaporate the water contained in the dispersion and to agglomerate the mixture of hot-melt polymer and activator, electron bombardment is carried out on the reverse side 2 b of the interlining support 2, that is to say the face which does not include the points 3 of polymer.
  • the electrons pass through the filaments or fibers 4 of the support 2 and penetrate into the point of polymer 3 where they meet the radical activator. Under the effect of these electrons, the radical activator generates free radicals which develop crosslinking reactions in zone 3 a of the hot-melt polymer.
  • the penetration depth of the electrons, the quantity and the choice of the radical activator are determined so that only zone 3 a of the hot-melt polymer which is in contact or in the immediate vicinity of the fibers or filaments 4 of the support and subjected to the action of the electrons undergoes the desired modification of the physicochemical properties, namely an increase in the melting temperature or in the viscosity of the hot-melt polymer.
  • Figure 2 shows schematically the separation of this first zone 3a, of modified structure, from the second zone 3b with non-modified structure by a discontinuous line 5. In fact the action is gradual in the thickness of point. However, it is created, under the controlled action of electronic bombardment, a differentiation in the thickness of each point of polymer 3.
  • This differentiation due to a certain crosslinking results in this first example by an increase of the melting temperature of the hot melt polymer constituting the first zone 3 a , this melting temperature remaining unchanged with regard to the second zone 3 b not significantly modified by the action of the electrons.
  • each point of hot-melt polymer, in which penetrate the electrons, constitutes a solid medium. Therefore, the cross-linking reactions, generated by free radicals, do not propagate only very weakly, unlike what might happen if it was a liquid medium.
  • the hot-pressing interlining 1 When the hot-pressing interlining 1 is applied under hot pressure to the item of clothing, at the temperature usually used for the hot-melt polymer in question, only the second zone 3b of each point 3 is brought to react, that is to say to exercise its adhesive power by melting the hot-melt polymer.
  • the application temperature is insufficient, due to the increase in its melting temperature, to react the polymer contained in the first zone 3 a .
  • the polymer of the second zone 3 b cannot creep through the wires or filaments 4 of the support 2, this creep being prevented by the first zone 3 a at point 3, which does not react and acts as a barrier.
  • the operating conditions, and in particular the penetration depth of the electrons are determined so that the relative thickness of the first area 3a is comprised between 10 and 50% of the total thickness from the point of polymer 3, preferably between 10 and 20%.
  • Polyamides or high-density polyethylenes or polyurethanes have been used as hot-melt polymers and as radical activators trimethylol propane trimethacrylate or trimethylol propane triacrylate in an amount of 5 to 20% by weight of polymer.
  • the hot melt polymer deposition was carried out at a rate of 9 to 16 g / m 2 on the interlining support.
  • An electron gun was used, with doses between 10 and 75 KGy and acceleration voltages from 100 to 200 kV.
  • the electron penetration depth is adjusted by interposing paper filters weighing between 50 and 100 g / m 2 .
  • this effect of increasing the temperature of the hot-melt polymer can also be obtained by adding a curable filler to the polymer dispersion, i.e. a charge which under the action of electronic bombardment will polymerize and harden irreversibly, thus no longer being reactivated thermally as is the case with the hot-melt polymer.
  • a curable filler i.e. a charge which under the action of electronic bombardment will polymerize and harden irreversibly, thus no longer being reactivated thermally as is the case with the hot-melt polymer.
  • the acrylic monomers are part of the curable fillers. So if he is itself of the acrylic type, the radical activator can also constitute partly a curable filler.
  • the electron bombardment takes place on the two facing support 2.
  • the operating conditions of the electron bombardment, the thermofusible polymers, and the activators are selected so to have the opposite effect to that of the first example, namely a decrease in the melting temperature and / or the viscosity of the polymers under the action of electron bombardment. With this difference, the considerations given above remain valid.
