Definitions

  • the present invention concerns a finishing method for textile material and the relative device.
  • the invention is applied in finishing treatments for fabrics and hosiery in order to give the feel of the fabric particular aesthetic effects, for example the ageing effect or pre-washed effect.
  • the invention can also be applied substantially to any type of textile material, both in the field of cotton and also in that of synthetic fibers, wool and hosiery.
  • One of the known treatments in finishing processes provides to draw the textile material around a plurality of rotary elements whose surfaces are lined with abrasive paper or other material having abrasive properties.
  • a machine that achieves this type of treatment is disclosed, for example, by EP-A-0.649.928.
  • EP-A-1.072.213 discloses a machine comprising a plurality of rotary brushes arranged on the periphery of a rotary drum and separated from each other by tensioning/stretching means which keep the fabric tense in the segment between one brush and the adjacent one.
  • WO-A-99/01602 discloses a grinding device comprising a rotary drum upon which a plurality of small rotary grinding cylinders lined with abrasive paper or the like are mounted.
  • Means for wetting or dampening the fabric are arranged upstream of the rotary drum, so the grinding cylinders are caused to exert their grinding action on a fabric at least partly wetted.
  • the present Applicant is not aware of an integrated machine of the type with rotary abrasive brushes, comprising long, thin and flexible filaments, suitable to treat wet textile material advancing continuously, with high efficiency and effective results.
  • the purpose of the invention is to achieve a method and a device for finishing textile material, suitable to obtain a very high quality result in a machine of limited bulk, simple in construction and functioning, extremely versatile and adaptable to different types of fabrics and different types of treatments to be done.
  • the device comprises a rotary drum or barrel on whose circumference a plurality of abrasive brushes are mounted, also rotary, consisting of a central shaft and a lining made of abrasive material.
  • the abrasive material consists of long thin nylon filaments, or other similar material, also of a composite type and at least partly flexible.
  • the abrasive material consists of thin and flexible filaments made of horsehair or similar material.
  • the abrasive material consists of thin and flexible filaments made of natural or artificial rigid bristle, or metal or other suitable material.
  • the action of the thin and flexible abrasive filaments of the brushes on a fabric which is wet or dampen allows to obtain "touch" and “hand” effects which are not obtainable if the fabric to be treated is dry.
  • the action of the thin and flexible filaments on a wet fabric is less accentuated and raises less the pile, so the pile obtained is softer, shorter and more dense.
  • the impregnation assembly comprises at least a tub inside which the fabric is made to pass, and at least partly immersed, before being sent to the drum.
  • the impregnation assembly comprises at least a spray or shower dispenser or similar.
  • the fabric is impregnated with substantially pure water while, according to a variant, the fabric is impregnated with water to which, for example, chemical products have been added.
  • the impregnation step is associated with a squeezing step which serves to regulate the humidity content of the fabric and to eliminate the excess water before the brushing treatment.
  • the impregnation tub into which the fabric is immersed is associated with heating means.
  • the squeezing assembly comprises at least a pair of rollers able to act with adjustable pressure on the fabric passing through.
  • the squeezing assembly is associated with rinsing means.
  • the abrasive brushes are distributed symmetrically on the circumference of the rotary drum and the number can vary according to their size and the size of the drum itself. According to the invention, it is preferable to have between 2 and 16 brushes, advantageously between 6 and 10.
  • all the brushes are moved synchronously in the same direction of rotation, clockwise or anti-clockwise, with a speed adjustable for example between 200 and 2000 rpm.
  • the brushes are made to rotate in groups in opposite directions, for example a first group of brushes rotates clockwise and a second group of brushes rotates anti-clockwise.
  • the drum can also be driven clockwise or anti-clockwise, at an adjustable speed preferably between 5 and 150 rpm. It comes within the field of the invention to achieve any type of combination of the direction of rotation of the drum and that of the brushes, or the groups of brushes.
  • each of the brushes there are means able to generate a transverse stretching/tensioning of the fabric in order to prevent it from shrinking, and to eliminate or prevent the formation of creases or curling of the edges which can form due to the tension transmitted by the abrasive action of the brushes.
  • the means are able to support the fabric so that it does not penetrate excessively between the brushes.
  • said stretching and tensioning means consist of small shafts with spiral threadings, associated with means able to make them rotate, on which the fabric is taken into contact in the intermediate segment between one brush and the other.
  • the stretching means consist of rollers on which a spiral is wound, made of steel wire or of profiles of a different conformation, substantially of a conventional type.
  • the stretching means consist of staves, bars, rollers or cylinders, fixed and rotating solid with the drum, including on their surface a threading or a spiral made of steel wire.
  • the fabric is stretched thanks to the difference between the speed of the fabric kept under tension between the means located at inlet to and outlet from the drum, and the speed of rotation of the drum itself.
  • said stretching/tensioning means consist of fixed staves or bars with a plane surface the purpose of which is to support the fabric and hold it still in a transverse direction to the direction of feed, so that no wrinkles are formed at the edges.
  • the device according to the invention provides means to draw the fabric arranged at inlet to and outlet from the rotary drum and equipped with systems to regulate the drawing action, so as to adapt it to different characteristics of the fabric and different working conditions.
  • the systems to regulate the drawing action comprise load cells.
  • the brushing device for wet fabrics 11 according to the invention is denoted generally by the reference number 10.
  • It comprises a rotary drum or barrel 12 on whose periphery abrasive brushes 14 are mounted, in this case six, also rotary.
  • the drum 12 is arranged inside a grinding chamber 25.
  • the drum 12 can rotate anti-clockwise (15a) or clockwise (15b), just as the brushes 14 can rotate individually, in groups or all together, both anti-clockwise (16a) and clockwise (16b).
  • the brushes 14 (fig. 2) comprise a central shaft 19, associated with relative drive means (not shown), and a lining 20 consisting of thin and long abrasive filaments, for example made of nylon or other synthetic material, or of horsehair, bristle, metal or other suitable material.
  • stretching/tensioning means 21 in this case consisting of fixed staves or plates; the function of the stretching/tensioning means 21 is both to hold the fabric 11 axially stationary, so that no wrinkles are formed at the edges, and also to support the fabric 11 so that it does not penetrate excessively into the abrasive lining 20 of the brushes 14.
  • the drum 12 is associated with an inlet drawing roller 18a and an outlet drawing roller 18b, possibly associated with systems to regulate the drawing action, not shown here, for example load cells.
  • the fabric 11 Before entering the drum 12 and into contact with the brushes 14, the fabric 11 is sent to an impregnation tub 13 into which it is immersed in order to be wet. According to a variant not shown here, it can be wet by a spray or shower system or other similar system.
  • spray systems 24, shower systems or similar are present in cooperation with the circumference of the drum 12 in order to wet the fabric 11, or keep it wet, during its travel around the drum 12.
  • a spray-type dispenser 24 is shown in cooperation with the brushes 14 in the segment where the fabric 11 is not gripped; the function of the spray-type dispenser 24 is to remove from the abrasive filaments 20 dust, waste, threads, fibers and other things that remain gripped on the brushes 14, and also to dampen the abrasive brushes 14 before contact with the fabric 11.
  • a squeezing assembly with rollers 17 which serves to eliminate the excess water and to reduce the humidity of the fabric 11 to a desired value before the start of the brushing.
  • the impregnation tub 13 is equipped with guide and transport rollers 26 which determine the path in which the fabric 11 is immersed inside the tub 13.
  • the impregnation tub 13 can also be associated with heating means 27, and/or can include means to add and dose additives such as softeners, resin-based substances or suchlike so as to achieve particular treatments and effects on the fabric 11.
  • the fabric 11 emerging from the drum 12 is picked up by the outlet drawing roller 18b and sent in this case to a rinsing tub 22.
  • the rinsing tub 22, in an embodiment not shown here, can be replaced by spray- or shower-type rinsing devices. It can also cooperate with heating devices and/or devices to add desired softening and/or treating substances. It also includes guide and transport rollers 26 which possibly determine (the line of dashes in fig. 1) a path of at least partial immersion inside in order to carry out the rinsing operation.
  • the humidity of the fabric 11 at outlet can thus be regulated to a desired value and suitable for the subsequent treatments to which the fabric 11 has to be subjected.
  • a drying assembly Downstream of the rinsing tub there may be a drying assembly (not shown here).
