Definitions

  • the present invention relates to a process and to an apparatus for the treatment of fabrics, and more in particular for bestowing upon a fabric a tendentially permanent effect of finish via the application of chemical products on their surface, basically by means of an initial step of application of the chemical products, an intermediate step of drying and solidification of the applied chemical products, and a final step of surface action on the fabric.
  • the present invention adds to the methods so far known a new methodology that enables modification of the physical and/or visual and/or tactile features of the fabric processed by applying, thanks to an innovative process, chemical products, which, interacting with a succession of physical effects conferred by the apparatus that implements the process, modify the surface and/or the feel of the fabric itself in a more or less permanent way.
  • Impregnation This is a complete immersion of the fabric in a bath, where the chemical agents are dispersed, said chemical agents penetrating throughout the thickness of the fabric, followed by squeezing between rollers and by a subsequent reaction in drying systems, such as air dryers or batteries of rollers.
  • the limits of the impregnation system are the excessive and useless consumption of the bath, the presence of product even where it would serve no purpose, the difficulty of double application carried out in succession (referred to as "wet-on-wet") of different materials, where the second agent is sometimes "refused” on account of the invasive presence of the first agent, and for which reason the first and second agents must at times necessarily be kept separate. Added to this is the high consumption of energy for drying.
  • Spreading This consists in a surface application of material (generally with high viscosity) via a levelling blade (doctor blade) and subsequent drying with known systems, typically applied only on a front surface (i.e., on just one face of the fabric) especially for large-scale production for technical products.
  • Limits of the system are the long times for setting-up and the waste of material, together with problems also for regulating minimum applications of product.
  • Foaming The chemical product is mixed in special machines that create foam of different cell size, which is then distributed and levelled out over the fabric using different mechanical methodologies.
  • the limits are the rather small number of types of products that can be used with this method, and the difficulty in controlling the applications. Also in this case, the treatment is applied only on one face at a time.
  • the object of the present invention is to provide a process and an apparatus suitable for enabling production, in an industrially advantageous form, of a series of effects, always exploiting the same plant, without any waste of chemical treatment products in order to enable production of both fabric samples and amounts of fabric on a large scale.
  • the present invention involves the use of some of the known, but improved, processes set in line according to an original sequence in order to obtain, in just one passage, a variety of desired results working on one and the same plant.
  • the bubble effect bestows a "casual" appearance upon fabrics with a classic structure so as to render them more “spongy” and “full-bodied” to the touch. Said effect is permanent on all the fabrics.
  • the glossy effect bestows a shiny appearance resistant to washing upon many fabrics, especially cellulose-based ones, that up to now had never been achieved or in any case obtained with different results in terms of effect/appearance.
  • the skin-dye effect envisages the use of dyes (of various sorts) that can be applied as overdyes in a uniform way or as a "melange" to obtain interesting effects of iridescent colour.
  • the apparatus for implementation of the process according to the invention envisages, in extreme synthesis, a series of stations that carry out in succession and in a continuous way on the moving fabric the following operations:
  • the fabric T after passing through a series of possible accessories designed to guide and prepare the fabric for the treatment, enters the application station designated as a whole by 1.
  • the application of the product must take place in just a superficial form, i.e., without impregnation of the fabric T throughout its thickness.
  • the application is consequently implemented by means of an adjustable spray system or more preferably by at least one kiss roll 2 that turns at a speed synchronized with respect to the rate of advance of the fabric T.
  • the kiss roll 2 picks up the product to be applied, in a liquid phase or in any case a fluid phase, from a tank 3 and transfers it onto the fabric T by applying it tangentially on the surface thereof resting on the roll 2.
  • the fabric soaked superficially on at least one face with the chemical product, advances towards the solidification station, designated as a whole by 4.
  • the chemical product specifically developed in terms of viscosity, is then solidified and fixed on the fabric via partial evaporation of the water or in general of the liquid phase present as dispersing agent of the chemical product.
  • the action of solidification must be controlled and sufficiently fast in order to block migration of the product towards the inside of the fabric T at the desired depth (which could even reach the opposite face).
  • the solidification station 4 includes a heated roll 5, which rotates in synchronism with advance of the fabric T.
  • the fabric T is run over the roll 5, resting thereon with its face opposite to the one on which the chemical product has been applied.
  • the solidification step can take place on a number of heated rolls, or else with the aid of an oven (either an air oven or infrared oven), without contact with the fabric.
  • an oven either an air oven or infrared oven
  • the source of drying energy will be set on the side opposite to the face of the fabric T treated with the chemical products, obviously in the case where said products are - as in the case of the example of Figure 1 - applied on just one of its faces.
  • the solidification step is preferably performed on the opposite face of the fabric, also at adjustable temperature and with or without contact.
  • the solidification step is conveniently performed on both faces of the fabric, at adjustable and possibly differentiated temperatures and with or without contact.
  • these two layers which cohere but are still in part distinct and set on top of one another, can optionally remain as such or else penetrate each other to a greater extent by means of mechanical and/or thermal energy, applied in an innovative and advantageous way when the chemical product is still in a semisolid state and hence modifiable and malleable, towards the underlying fabric T, the fibres of which still contain humidity and are hence more readily deformable.
  • the fabric T then reaches the finishing (modelling) station, designated as a whole by 6, where - with the chemical product applied on its surface - passes through a series of opposed rolls 7 that bestow thereupon the desired finish with a more or less marked reduction of the thickness and/or smoothing of the surface and/or modification of the surface roughness.
  • the fabric T advances through at least two pairs of rotating heated and opposed rolls 7, 7', set in adjustable pressure in such a way as to bestow upon the fabric and the chemical product applied thereon the final desired appearance.
  • the rolls 7, 7' may also have surfaces with different finishes: in a preferential form, a roll 7, 7' of each pair will have a very rigid metal surface, and the other opposed roll 7, 7' will present its surface coated with elastically deformable material.
  • the fabric T is finally gathered in laps or rolls.
  • the distance between application and drying must necessarily be reduced to prevent migration of the product towards the inside of the fibre of the fabric.
  • the residual humidity which is controlled and can be adjusted (possibly with the use of automated electronic systems) is a fundamental part of the process.
  • finishing finishing of the fabric it is in fact expedient for the fabric, coming from solidification, to be immediately treated. Otherwise in fact, if it were wound on a roll (or, worse still, if it were folded in layers) prior to the finishing step, a far from optimal non-homogeneous result would be obtained that would be difficult to repeat at an industrial level on account of the natural effect of evaporation and/or of cross-linking of the chemical products applied on the fabric.
  • the surface application is advantageous because it involves a smaller application of liquid and hence a reduced consumption of energy during solidification for evaporating the water in excess.
  • the concatenated sequence of the events of application-solidification-finishing enables optimization of the process with reduced use of staff, optimal control of the process parameters, extremely short times for preparation and modification of results.
  • the final effects that can be successfully obtained on the fabrics treated according to the invention are at least three: bubble effect, glossy effect, and skin-dye effect. Additional different effects may, however, also be envisaged.
