Definitions

  • This invention relates to the manufacture of textile materials, and is particularly concerned with the finishing operations carried out on pile 5 fabrics. It is an object of the invention to provide an improved method and apparatus for raising or brushing the pile of pile fabrics.
  • vapour in the raising or brushing of pile fabrics, vapour, e. g. a softening 10 vapour, is applied to a part of the fabric which is being subjected to raising or brushing.
  • steaming affords a satisfactory vapour treatment, and in the subsequent description reference will be made only to theme of steam.
  • the pile may be raised by means of rotatingbrushes, card cylinders or other means for the purpose, and may be carried out uniformly over the whole of the fabric or in such a manner as to produce differential surface 20 effects on the fabric.
  • the invention is applicable to pile fabrics generally, such as plush, warp pile velvet, ring velvet of weft pile velvet, whether the pile consists of cotton, wool, mohair, alpaca, silk, artificial silk 25 or of any other material and whatever the nature of the ground by which such pile is backed.
  • the invention is, however, particularly applicable to fabrics having a pile of artificial silk.
  • the invention is especially productive of very good -30 results when applied to fabrics having a pile consisting of organic derivatives of cellulose, such as cellulose esters, e. g. cellulose acetate, formate, propionate, or butyrate, or cellulose ethers, e. g. ethyl, methyl or benzyl cellulose, which fabrics 35 cannot be effectively raised or brushed by the usual methods.
  • an apparatus comprising means for raising the pile of the fabric, in association with means for 40 treating the fabric with steam simultaneously with pile raising and on the same part of the fabric.
  • a steam box may be provided,'between which box and the 45 pile raising means the fabric is passed.
  • the edges of the steam box over which the fabric passes should be of such a nature as to ensure that the steam leaving the box can do so only by passing through the back of the fabric to the face.
  • Fig. 2 shows, in side elevation, means for lifting the pile raising member
  • Fig. 3 is a front elevational view of the means 5 for lifting the pile raising member.
  • the fabric l passes round guide rollers l l and I2 and over a tensioning roller I3, the rotation of which is braked by a band 14 weighted at l and engaging a brakedrum 16 connected to the roller l3.
  • the tensioning roller l3 From the tensioning roller l3, the fabric I0 is led over the top of a steam box I1 and to a porcupine drawing roller la, the needles of which engage the back of the fabric and draw it through the machine.
  • a steam pipe I! perforated on its underside passes centrally through the steam box l1 and ejects steam downwardly against a baflle plate 20.
  • the steam is deflected upwards and dis- 20 tributed evenly throughout the box [1 by the baflie plate 20 so as to pass evenly through the fabric l0 stretched over the top of the box ll.
  • the baffle plate 20 is perforated and allows moisture to leave the box by a drain 2
  • the substantially flat pile A of the fabric I0 is raised to the upright position shown at B by means of a card-covered cylinder 22, which is mounted at a suitable height over the steam box i1 and rotated to exercise a teaseling action upon the pile A while the fabric is being subjected to the action of the steam applied from the box II.
  • the cylinder 22 may be driven at a surface speed greater than that of the fabric or may be driven at a relatively low speed, depending upon the effect desired in the finished fabric.
  • a stationary card may be employed in place of or in addition to the rotatable card cylinder, in order to comb out the pile in one direc- 40 tion, as is required for example, by way of preparation for dyeing processes.
  • the cylinder 22 may be heated by steam or otherwise, for example, by passing steam through a hollow shaft so as to prevent any condensation from taking place.
  • card wire of rustless metal should be used, and/or that it should be secured in the card clothing in the manner described in U. S. application S. No. 634,731 filed September 24, 1932 corresponding to British Specification No. 27,323/31 filed 1st October, 1931.
  • In'that specifl'cation is described a method of replacing the rubber employed in the card clothing with an V ester, ether or ether-ester of a polyhydroxy compound of high molecular weight, such as cellulose or polyvinyl alcohol. In this'manner injury to the card clothing and to the fabric being treated on account of corrosion of the card clothing under the action of steam is avoided.
  • the upper edges of the steam box I l are smooth and level to allow the fabric 10 to fit very closely so as to prevent the escape of steam.
  • the length of the box may equal the width of the fabric, but in order to prevent the escape of steam when the fabric width is less than the length of the box, suitable plates (not shown) may be used to blank over the ends of the box not covered by the fabric.
  • Raised pattern effects and designs of any description are obtained by raising the pile through a stencil 25 loosely surrounding the cylinder 22.
  • the stencil 25 is cut to any desired pattern and rotates at a surface speed equal to that of the fabric l and may contain exactly one or more repeats of a' design.
  • the card clothing penetrates the open parts of the stencil, thereby raising the pile coming beneath those parts but is masked from the fabric beneath the blank parts of the stencil, which areas are thus allowed to pass through the machine unraised and may even be further flattened by the pressure of the stencil.
  • a beater-fan 23 which serves to free the fabric from'flufi and loose material.
  • the extremities of the fabric may conveniently be sewn together to form an endless band.
  • cylinder lifting means may be used similar to the glossing bar lifting means described in U. S. application S. No. 637,434 filed October 12, 1932, corresponding to British Patent No. 391,191.
  • the shaftof the cylinder 22 may be connected at each end to a lever 2 6 fulcrumed at 21 on a pillar 28 attached to a convenient part of the machine.
  • the lever is weighted at 29 to provide pressure for the cylinder 22.
  • Vapours other than steam may be used instead of, or in admixture with steam, in order to produce augmented or modified results.
  • vapours of a solvent or softener for the cellulose derivative e. g; acetone vapours
  • a cowl 24 connected to a suction system is adapted to cover the area over the box I! so as to conduct ing pile fabrics.
  • Process for effecting substantially permanent raising of the pile of a pile fabric, wherein the pile contains yarns of cellulose acetate which comprises mechanically raising the pile over at least part of the area of the fabric by drawing the fabric .past a pile-raising member with its pile side in contact with the member, and simultaneously applying steam vapor-of a solvent for the cellulose acetate to the part of the fabric in contact with the pile-raising member.
  • Process for effecting substantially permanent raising of the pile of a pile fabric, wherein the pile contains yarns of an organic derivative of cellulose which comprises mechanically raising the pileover at least part of the area of the fabric by drawing the fabric past a pile-raising member with its pile side in pressing contact with the member, leaving the back of the fabric exposed as it passes the member, and applying vapor of a solvent for the derivative of cellulose to the said exposed back of the fabric.
  • Process for effecting substantially permanent raising of the pile of a pile fabric, wherein the pile contains yarns of an organic derivative of cellulose which comprises mechanically raising the pile over at least part of the area of the fabric by drawing the fabric under tension past a pile-raising member with its pile side in contact with the member, deflecting the tensioned fabric by the member, and simultaneously applying vapor of a solvent for the derivative of cellulose to the back of the part of the fabric in contact with the pile-raising member.
  • Process for effecting substantially permanent raising of the pile of a pile fabric wherein the pile contains yarns of cellulose acetate, which comprises mechanically raising the pile over at least part of the area of the fabric by drawing the fabric past a pile-raising member with its pile side in'pressing contact with the member. leaving the back of the fabric exposed as it passes the member, and applying steam vapor of a solvent for the cellulose acetate to an enclosed space abutting on the back of the fabric opposite the pile-raising member.
