Definitions

  • the present invention relates to a process for the steaming of fabrics on a stretchable support as well as an apparatus for carrying out this process.
  • the fabric freely fed without stretches or accumulations, is gradually induced to shrink by means of a continuous, smooth mechanical action which, in combination with the steam effect, brings to those desired best results, never obtained so far and remained theoretical.
  • the process according to the invention is characterized by the steps of freely feeding, without tension, the fabric to be treated on a stretchable support being elongated in the contact area under a pull action, causing said support to be continuously forwarded along a fabric steaming region while at the same time the elastic recovery of the support gradually occurs, whereby the support shrink causes an increasing fabric crimping during the treatment, possibly also in the width, not only in the length direction.
  • an apparatus which carries out the above-mentioned process and comprises an endless web formed of a perforated stretchy support being wound about at least two rollers having different peripheral speeds, with a steam generator capable of liberating steam through the upper path of said endless web, along a portion thereof which is downstream of the roller having the greatest peripheral speed, in the proximity of which the fabric to be treated is freely fed onto said support.
  • the roller that is downstream of said steam generator, having a lower peripheral speed will be preferably provided with circumferential grooves in order to assist the support in its elastic recovery also in the transverse direction, and therefore the fabric shrink in the width direction.
  • the process according to the invention provides for using, as a support for continuous steaming a fabric 6, a stretchable material 5 which is wound, as an endless web, about at least two motorized rollers 1, 2.
  • the material of support 5 will be elastic, so as to be able to stretch especially in the longitudinal sense, but preferably in all directions, upon a sufficient mechanical thrust, and to elastically return to the original dimensions. It will be clear that in this case it is not a matter of natural elasticity only shown by whichever material, especially fabrics. As a matter of fact there is meant here a mat formed of e.g. a multiplicity of elastic rubber bands, or a fabric woven by elastic fibres such as those known under the tradename "lycra". It will be appreciated that the stretchable support material should be perforated or anyhow caused to be pervious to the steam issued by an underlying steam generator, of known type, designated 4 in the drawing.
  • roller 1 is driven to rotate at a greater peripheral speed, such as 20-30% higher than the speed of roller 2, each roller being independently driven.
  • a greater peripheral speed such as 20-30% higher than the speed of roller 2, each roller being independently driven.
  • the pull exerted by roller 1 will cause the support to be stretched along the lower branch and the same to gradually return to the conditions of normality along its upper branch.
  • the roller 1 Upon leaving the roller 1, at the zone designated 7 where the support contacts fabric 6, the latter is fed by cylinder 3 at the same speed of roller 1 or at most a slightly greater speed, since it is preferred to have a feeding slightly in excess rather than tensions caused by a pull action made by the support 5.
  • roller 2 is preferably grooved being formed with circumferential grooves 8 which assist the support 5 web in its elastic recovery also in the direction perpendicular to the arrow F direction. Therefore the fabric 6 will be induced to shrink not only in the length, but also in the width direction, with a dimensional conditioning which is as much iso­tropic as possible.
  • rollers Although only two rollers have been shown, about which the stretchable support web is wound, they could also be in a number more than two.
