Definitions

  • the invention relates to a method for ageing and softening of fabric and to a machine for carrying out said method.
  • a machine in which, in combination with a wall against which the fabric is delivered to strike thereon and receive the action therefrom, there are provided: a fabric-transferring duct; means for feeding said fabric to said duct; and means for conveying a transfer air stream to the outlet of said fabric-transferring duct in order to pneumatically throw the fabric against said wall which is grid-shaped and angularly adjustable.
  • the conveyor means have a section forming an annular nozzle around the outlet of the duct for the fabric; the section forming the nozzle made up by the cooperation of a shaping of the transfer duct and a shaping of a pneumatic pipe surrounding said fabric-transferring duct; these two shapings may be axially adjustable one with respect to the other.
  • Means are provided for feeding the fabric, the speed of these means being set according to the fabric demand.
  • a fan sucks from the inside and/or the outside of the working housing and blows in said pipe upstream of the shapings. This known machine is intended for washing, breaking and fulling of fabric.
  • a method for ageing and softening of fabrics wherein in a washing and fulling machine comprising a wall against which the fabric is made to strike, a duct for the dragging of the fabric, means to feed said fabric to said duct, means to convey a dragging air stream to the outlet of said duct, the fabric is made to violently impact onto the wall, while the humidity, temperature conditions are controlled by exchanging and heating air in the machine.
  • ageing and softening of fabric is obtained in the above mentioned machine with the fabric in substantially dry conditions.
  • the ageing and softening of fabrics is achieved with high speed of the pneumatically transferred fabric and with consequent violent strike thereof onto the grid of a washing and fulling machine.
  • a new and unexpected use of such a machine and a new method for ageing and softening of fabrics are obtained.
  • the use of a pneumatic duct for the transfer of the fabric and its lounching against the grid allows reaching of very high speeds of the fabric, up to 1000 m/min, which are not achievable in common ageing and softening machines.
  • a limited degree of humidity e.g. 40% of the fabric weight
  • the degree of humidity is determined by the intake of water, through nozzles provided within the duct for the pneumatic transfer and/or downstream of the opposite grid at the outlet of the duct.
  • hot air may be used for drying the fabric.
  • the ageing and softening process is carried out controlling the humidity and temperature conditions by means of air heating and exchange.
  • the invention refers also to a machine for treatment of fabric, comprising: a wall against which the fabric is made to strike; a duct for the transfer or dragging of the fabric, means to feed said fabric to said duct, means to convey a dragging air stream to the outlet of said duct.
  • the machine further comprises means for the air exchange and air heating.
  • Such a machine can be indifferently used for carrying out a washing, breaking and fulling treatment of the fabric and/or an ageing and softening treatment of the same, under dry conditions and/or under suitably controlled humidity and temperature conditions.
  • the machine can be further provided with nozzles located within the duct for the pneumatic transfer of the fabric and/or downstream of the grid against which the fabric is made to strike, said nozzles and said air heating means providing for the air conditioning, the restoring of humidity during treatment and the drying of the fabric during the final stage of the treatment.
  • the machine may further comprise an air sucker at the back of the concave grid, able to suck residual carbonization particles of a fabric carbonized by a dry process and treated in the machine.
  • An air sucker may be provided also in the zone where the fabric is withdrawn through the pneumatic duct.
  • a gravity-operating discharge in the rear of the grid may also be provided.
  • numeral 1 indicates a tank formed by the bottom of a housing that may be closed in its upper part at 1A and has suitable access means with inspection and control doors like that indicated by 3.
  • the grid 3 is concave on the active side thereof and, in particular, may have two portions 3A, 3B at an angle to one another.
  • a transfer air jet is delivered, which drags and throws the fabric T at high speed against the grid 3; the fabric makes part of a roll of cloth or of more rolls of cloth having a closed (simple or multiple) ring arrangement; the fabric piles up in T1 on the bottom of the housing 1, and is recycled over and over again and made to impinge against the grid 3 (3A, 3B).
  • the fabric is recalled upwardly according to arrow fT through rings 9 by a system of two transfer cylinders 10 and 12, at least one of which being driven into rotation in an adjustable manner and the other being urged towards the first one and possibly also driven into rotation at the same peripheral speed, or even by only one matching cylinder, like that indicated by 10 or that indicated by 14.
  • the fabric is fed through a mouthpiece 16 into a duct 18 for the pneumatic transfer of the fabric.
  • This duct 18 is inclined upwardly and towards the grid 3, and has a terminal portion 18A in form of a nozzle within a curved and wide part 20A of a blowing duct which is tapered in 20B around the portion 18A in form of a nozzle and possibly extends with a slightly throttled portion 20C and then with a widen portion 20D into alignment with the axis of duct 18 and upwardly oriented towards the grid-like wall 3.
  • the assembly 18A, 20A, 20B, 20C, 20D makes up a Venturi nozzle for the transfer of the fabric (coming from duct 16, 18) by pneumatic effect, through air blown by a fan 24 overhanging the wall 1A; said fan 24 sucks through a mouth 28 from the housing, and partially or totally through a mouth 30 from the outside via a thermal battery 32.
  • Humidification nozzles are provided within the air circuit, in order to have the air conditioned as for humidity and temperature as well, the inlet from the inside being more or less shut by a gate 34.
  • the air stream moved forwards by the fan 24 makes up a very fast pneumatic transfer means for the fabric outcoming from the outlet 18A of duct 18, so that said fabric is dragged along by the air stream coming from the duct 20A and flowing inside the annular passage between the portion 18A in form of a nozzle and the duct 20B, through the nozzle formed by the portions 20C, and inside the duct 20D.
  • the strong air jet with which the nozzle acts over the fabric coming out from the outlet 18A drags said fabric along the duct 20D and projects it violently against the grid 3, where the fabric treatment takes place.
  • the fabric may be made to acquire a degree of humidity of e.g. about 40% of the fabric weight, and at the end of the process a normal drying of the fabric can be achieved through heating.
  • the machine maintains its performance capabilities with respect to the washing and/or the fulling of fabrics by providing proper setting, suitable wet processes and speed reduction.
  • Suctions from openings like that indicated by 40 and/or that indicated by 42 allow the discharge of air mixed with water, of powders and/or carbonization residues (in case of a dry process).
  • the treatments are effective and very fast, even with very long rolls of cloth.
