Definitions

  • This invention relates to a method for producing a woven/non-woven thermoadhesive product particularly for interfacings comprising dots melting at differential temperature, in which heat-molten resins are extruded and deposited on the woven/non-woven fabric support and then covered with resin granules of a different melting point by means of a resin strewer. The fabric is then cleaned of all the excess deposited granules to leave it clean and ready for use.
  • the present invention also relates to a plant for producing a woven/non-woven thermoadhesive product, the plant comprising a conveyor belt of low adhesive power.
  • thermoadhesion concept and the double dot system they start by depositing resins in paste and powder form.
  • thermoadhesive material can penetrate into the thickness of the fabric substrate and cause it to harden.
  • feel of the fabric is strongly compromised.
  • a transfer support is covered with droplets of an at least partly thermoadhesive substance, these droplets then being heated to ensure adhesion.
  • the droplets are then brought into contact with the fabric without heating it, to enable the thermoadhesive substance to be transferred from the transfer support to said woven/non-woven substrate but without penetrating into the substrate.
  • the object of the present invention is therefore to provide a method for producing a product in woven/non-woven thermoadhesive form for use in the clothing field, which in the light of the drawbacks consequent on the use of methods of the known art offers two main characteristics, namely that the thermoadhesive substance which is deposited on the fabric substrate remains on the surface of the product, ie does not penetrate into it and therefore does not produce stiffening and traversing problems, and that the fabric substrate used, which can also be of non-woven type, is not subjected to excessive heating and hence does not suffer deterioration during production.
  • the invention therefore firstly provides a method for producing a woven/non-woven thermoadhesive product particularly for interfacings for use in the clothing field, characterised by presenting dots melting at differential temperature and comprising the following processing stages in succession: melting heat-sensitive resins of any type and then extruding them onto an indented roll of low adhesion material; transferring the extruded material from the indented roll onto a preheated conveying transfer belt of medium adhesion material; preheating the material on the transfer belt and passing it from the transfer belt to a woven/non-woven substrate; activating with positive electrical charges; depositing resin microgranules having a melting point different from that of the base material; fixing the dots by passage through a micrometrically regulated cooled calender; deactivating the resin material with negative electrical charges; cleaning the woven/non-woven substrate by beating and blowing, followed by sucking off the material not retained by the substrate.
  • the invention also provides a plant for implementing said method, comprising a first indented roll of low adhesion material arranged to receive the thermoadhesive material by extrusion by a pump connected to it, first heating means positioned in proximity to the roll, guide and support means with a medium adhesion surface for thermoadhesive material transfer, a second discharge roll provided with associated second heating means, and cleaning means for the transfer support; said discharge roll being associated with a deviation and receiving roller positioned along a woven/non-woven product processing line along which means are also provided for strewing low melting-point resins over the thermoadhesive material, means for applying alternate positive and negative electrical charges to the thermoadhesive material, means for fixing the thermoadhesive material to the woven/non-woven substrate, beating means and blowing means associated with means for sucking off the excess material.
  • the reference numeral 1 indicates an extruder of pump type, but which can equally be of another type, in which the granules of heat-sensitive material are melted. Any type of heat-meltable granule can be advantageously used, according to the method of the present invention, to form the substrate for the subsequent resin dot of differential melting point.
  • the extruded material is transferred via one end 2 of the extruder 1 to an indented roll 3, the indentations of which are in a number, diameter, depth and design which depend on the quantity of material to be deposited.
  • the shape of the indentations in the roll 3 is chosen in accordance with the dot shape to be obtained on the fabric.
  • a preferred shape for example is a ring shape.
  • the advantage of this shape is that the dot which then forms on the fabric layer tends to assume a dish shape, with the consequent advantage of offering a greater containing capacity for the resin microgranules which are later strewn over it in accordance with the method of the invention.
  • the indented roll 3, onto which the molten material is fed at a temperature exceeding 200°C, is conveniently controlled to a temperature of 150-180°C, and being of low adhesion material is able to easily transfer the thermoadhesive material dots onto a belt of medium adhesion material at the point in which it comes into contact with the roll 3.
  • thermoadhesive material dots 7 forms part of a conveying system for the thermoadhesive material dots 7, which comprises an assembly of temperature-controlled rollers 8 arranged to enable the belt to slide along the roll 3 at one end, and at the other end by means of a discharge roll 9 to discharge the dots 7 onto a woven/non-woven substrate 10 running adjacent to it.
  • the belt 6 and the dots 7 can be conveniently temperature-controlled, at 150-180°C for the former and at 70-90°C for the latter, by two infra-red banks 12, 13 positioned at the periphery of the rolls 3 and 9.
  • the dots conveyed by the belt 6 undergo a change of state at their inner and outer surfaces to become molten dots.
  • thermoadhesive dots pass from the belt surface to a woven/non-woven substrate 10 passing around the roll 9, as this substrate is of greater adhesion.
  • One of the advantages of the method of the invention compared with the traditional method is that the woven/non-woven substrate is not subjected to thermal shock with consequences apparent only later, and hence resulting in a better feel and a saving in energy.
  • the belt 6 After transferring the thermoadhesive dots to the woven/non-woven substrate 10, the belt 6 proceeds along its endless path and is deviated by the rollers 8 to the indented roll 3.
  • the rollers 8 Of the rollers 8, one is a cold roller temperature-controlled at 30-50°C and is positioned immediately downstream of the roll 9 to cool the belt and enable it to be cleaned by a scraper 14 associated with the next roller.
  • a collection tray 15 collects the pieces scraped from the belt so that they can be salvaged.
  • the fourth and last roller 8 returns the belt to a predetermined temperature to enable it to repeat the cycle by again collecting the extruded dots from the roll 3.
  • the woven/non-woven fabric is then moved through the subsequent stages of the method of the present invention by the following device.
  • thermoadhesive dots thus charged with energy absorb in an optimum manner resin microgranules of different melting point strewn by a resin strewer arranged along the path of the fabric.
  • the woven/non-woven fabric is then passed through a further calender 22 maintained at a temperature of about 17-20°C, by which the resin microgranules strewn by the resin strewer 20 are incorporated into the thermoadhesive dots 7.
  • the device of the invention also comprises a negative charge applicator 23 for negatively charging the dots 7, and a series of carrier rollers 24 with a suction device interposed in a position corresponding with a blower 26 and a beater 27.
  • a negative charge applicator 23 for negatively charging the dots 7, and a series of carrier rollers 24 with a suction device interposed in a position corresponding with a blower 26 and a beater 27.
  • the described method results in a perfectly frusto-conical or drop-shaped dot, with resultant improvement both in adhesion and in the feel of the fabric.
