Description

  • The present invention relates to a method for the treatment of one of the sides of a flat-structured material having a large surface development and highly reduced thickness with respect to this surface development, from a minimum working height (weft) to a maximum of 2.50 m (2,500 mm) which, when necessary, can be wrapped into a cylindrical roll, both at the inlet (before treatment) and at the outlet (after treatment). The method substantially comprises the contact of the surface of interest with a moving brush or pattern-shaped cylinder, which, in turn, is in contact with another non-porous cylinder, the latter also in movement and partially immersed in a liquid bath in which it is soaked and of which it soaks the surface of the previous solid. The latter, in turn, transmits the effect to the surface of the material to be treated: the composition and temperature of the liquid bath are suitably selected in relation to the result to be obtained on the surface of the material to be treated. The method also envisages that the material thus treated be finally sent for suitable finishing treatment: in particular, the material treated is sent to a heated cylinder having on its circumference from two to infinite traces with rounded steel bars and/or a completely smooth cylinder. The material slides to the cylinder by means of a closed-ring felt, where it is dried and pressed between the two bodies (heated cylinder and felt).
  • By extension and as a logical consequence, the present invention also relates to the devices used for the embodiment of the method defined above.
  • More specifically, the object of the present invention relates to a method for preparing fabrics having different "feel effects" and/or coloured "visible effects", obtained by treating the same on one side only.
  • The use of machines for effecting the polishing of fabrics is known in the practice of the textile industry. For the polishing of pile fabric, these machines are equipped with a basin in which a bakelite cylinder is half immersed in a bath of cold water and chemical products.
  • A brush is situated above this cylinder, which, by pressing against the cylinder, collects the liquid from said cylinder and transfers it to the pile side of the fabric, i.e. onto the "loden"-type straight side.
  • The fabric thus treated is normally sent onto a heated cylinder, equipped with knurled combs, which completes the polishing operation of the pile and effects the alignment of the pile. It is also known that fabrics with particular "feel effects" can be prepared by applying specific chemical products to the same, according to procedures which envisage the complete immersion of the fabric in the solution (or suspension) of the chemical product of interest, (foulard) and the subsequent drying operation of the fabric thus impregnated; this kind of procedure inevitably leads to the excessive waste of chemical products and, furthermore, it is also impossible to obtain a fabric with two sides treated in different ways. As is known, immersion procedures can also be avoided by effecting surface treatment of the fabrics by means of printing or laying operations on one side only, allowing fabrics to be obtained with patterns on a white or on a coloured background.
  • The Applicant has now found that it is possible to effect treatment on one side only of the fabric, using reasonable quantities of chemical products, by programming their distribution on one side only of the fabric of interest and thus with the possibility of having a different treatment on the other side, if necessary and/or desired. In this way fabrics are produced with the desired feel and/or coloured visible effect, on one side and a different feel or visible effect on the other, resorting to the use of a machine such as that described above for effecting the polishing of pile fabric, exceeding the limits of use with single variations which confer a new and unexpected structure, and whose use can also be surprisingly extended beyond the textile industry.
  • The object of the present invention relates to a method for the treatment of one of the surface sides of a flat-structured material with a large surface development and highly reduced thickness with respect to said surface development, from a minimum working height to a maximum of 2.50 m which can be wrapped into a cylindrical roll, both at the inlet and at the outlet, comprising:
    1. a) putting said material, on the side of the surface of interest, in contact with a moving brush or pattern-shaped cylinder ;
    2. b) regulating the reciprocal position between the surface of the flat-structured material to be treated and the moving brush or pattern-shaped cylinder, this in turn being in contact inside a liquid bath with a moving cylindrical body made of bakelite or a non-porous material;
    3. c) moving said cylindrical body inside said liquid bath to allow the above liquid to be transferred onto the surface of the adjacent brush or pattern-shaped cylinder;
    4. d) programming the temperature and also the composition of said liquid bath in relation to the treatment to be effected on the surface of interest of the material to be treated;
    5. e) subjecting the material thus treated to finishing operations; and wherein
      • ** the brush or pattern-shaped cylinder has a fixed rate identical to that of the material to be treated,
      • ** the pressure on the brush or pattern-shaped cylinder is regulated as a result of the mechanical movement of a cylinder;
      • ** the cylindrical brush rotates in an anticlockwise direction and has a fixed rate and the cylinder immersed in the liquid bath rotates in an clockwise direction, at a varying rate.
  • In step (a), the moving brush or pattern-shaped cylinder is preferably a collecting brush of the liquid made of animal, vegetable or synthetic fibre (nylon, etc.). The brush can be made up of aligned fibres with a uniform height or aligned fibres alternating with empty spaces. Depending on the type of treatment, the brush can consist of a pattern-shaped cylinder made of various materials (figure 3) of which the rate of the patterned cylinder is the same as the rate of the fabric being treated. Figure 3 shows an illustrative detail of this solid. As already mentioned, the method according to the invention has a general valence: materials which can, in fact, be subjected to the above surface treatment are: natural and synthetic, or artificial fabrics; non-woven fabrics, and, according to a more general definition, materials from any type of natural fibres such as vegetable or animal fibres; all kinds of synthetic and artificial fibres; vegetable fibres such as linen, cotton, ramie, hemp, jute fabrics, furs and others; all kinds of paper; animal fibres such as silk, woollen fabrics such as, for example, cashmere, alpaca, vicuna, mohair and furs; or hide, furs and leather in general; synthetic fibres such as polyester fabrics, polyester furs and acrylic fibres; artificial fibres such as fabrics made of viscose, nylon and others, or plastic materials such as polypropylene, polyethylene, PVC, PET, furs and the like.
  • In particular, the method for the treatment of one of the sides of a flat-structured material with a large surface development and highly reduced thickness with respect to said surface development from a minimum working height (weft) to a maximum of 2.50 m (2,500 mm), envisages that the material to be treated (M in figure 1) enter into contact (step a) on the part of the surface of interest with a cylindrical brush, on which it presses due to the mechanical movement of a cylinder (C in figure 1), creating a lesser or greater distance between the fabric and the brush (step b). The rotating brush (B in figure 1), comes into contact with a cylindrical body (A in figure 1) which undergoes a rotating movement, regulated (step c) in the opposite direction to that of the cylindrical brush. This second cylinder (A) is partially immersed in a liquid bath, whose temperature and composition are programmed (step d) in relation to the effect to be obtained on the material with the treatment itself; once the material has undergone controlled impregnation, it is passed (step e) over a heated cylinder having on its circumference from two to infinite traces with rounded steel bars and/or a completely smooth cylinder. The material slides to the cylinder by means of a closed-ring felt, where it is dried and pressed between the two bodies (heated cylinder and felt). The above cylinder (Q-Q1) on which the finishing operations are effected, consists of an empty cylinder for containing the heating resistances; it does hold knurled combs but has smooth surfaces (Q1), or is equipped with rounded steel bars (Q). The cylinder has a rate ranging from 200 to 800 revs per minute and is heated to a temperature of up to 220°C. The material (M) (figure 2) runs to the above cylinder by means of a closed ring felt (a1) and at a varying pressure by means of pneumatic pistons. In this phase, the material is dried and pressed between two bodies: one which is metallic, cylinder (Q-Q1) and one felt (a1).
  • The process scheme of the method according to the present invention appears more evident by referring to the drawing of figure 1 (already mentioned above) provided herein for illustrating the method according to the present invention. In this drawing, A is the cylinder which is immersed and rotates in the bath L, B is the brush or pattern-shaped cylinder which enters into contact with said cylinder and with the surface of the material M which is entrained by the carrier cylinders C1, C2 ... Cn and presses on the brush B due to the mechanical movement of the cylinder C. It is finally treated in the finishing cylinder (Q-Q1). According to specific demands and effects, the cylinder C can be raised to prevent the conveyed product from being transferred over the material M, and then return again to exert pressure in alternating and non-alternating phases.
  • The brush or pattern-shaped cylinder, indicated in figure 1 with B, is rotated in an anticlockwise direction and has a fixed rate. The brush or pattern-shaped cylinder can also have a horizontal transfer movement (oscillating) to the right or left (coming and going) which allows the desired coloured "visible effect". The cylinder A is made of bakelite or a non-porous material, and rotates in a clockwise direction.
  • The bath, indicated in figure 1 with L, consists of water, chemical products, or a solvent selected from those normally used in the embodiment of processes in the textile industry or a mixture of water and chemical products, and/or a mixture of solvents and chemical products, and/or a mixture of water, solvents and chemical products.
  • In relation to the surface treatment of the material to be produced, the bath contains, dissolved, dispersed or suspended in water and in the solvents indicated above, one or more chemical products which can be selected from textile auxiliary products (for dyeing, post-dyeing, refinishing, innovative finishing); detergents; products for the dyeing and finishing of leather and furs; products for the dyeing and surface treatment of paper; cosmetic products, such as, for example, creams, milk, balsams, perfumes; decorative products (glitter and sequins in general).
  • In the method according to the present invention, the temperature of the bath L is programmed and controlled. Said temperature, selected within the range from room temperature to 90°C, is controlled and regulated by means of a rheostat inserted in a structure or surface positioned inside the tank; the heating however is always effected by means of indirect vapour, in order to avoid any possible pollution of the liquid inside the tank (V in figure 1), and/or by means of electric resistances.
  • The material (M in figure 1) presses on the brush B due to the mechanical movement of the cylinder (C in figure 1) causing a lesser or greater distance between the fabric and the brush (B), consequently exerting an extremely variable pressure depending on the type of treatment. Said cylinder (C) contemporaneously rotates in synchrony with the advancing of the material on the carrier cylinders. The material moves at a rate ranging from 1 meter per minute to 25 meters per minute until it reaches the finishing cylinder, Q-Q1 in figure 1 and in detail in figure 2.
  • The method according to the invention is particularly advantageous in producing specific feel effects on textile materials which are thus treated on one side only and, if necessary or desired, can be subjected to a different treatment on the opposite side; the distribution of the product takes place on one side only of the fabric, with a partial and reasonable penetration inside the thickness.
  • Another object of the present invention, of which it is an integrant part, relates to the device for embodying the method for the surface treatment of flat-structured materials, as defined and illustrated in detail in the previous description and figures. In particular, included in the objectives of the present invention is a device which is suitable for the embodiment of the method, comprising:
    • a set of two cylindrical solids in reciprocal movement, of which:
      • one consists of a brush or pattern-shaped cylinder,
