Definitions

  • This invention relates to improved; processes for the treatment of fabrics and in particular the treatment of fabrics made of cotton or other cellulosic fibresor containing cotton or other cellu- 5 losic fibres in association with cellulose derivatives, for example cellulose acetate or other cellulose esters or cellulose ethers or withanimal nbres, for instance wool or silk.
  • cellulose derivatives for example cellulose acetate or other cellulose esters or cellulose ethers or withanimal nbres, for instance wool or silk.
  • h m j m The object of the present invention isto proof the cotton or other cellulosic fibre partly or wholly from such fabrics, andmore particularly, the, invention is concerned with new processes for the production of ornamental. effects, for instance lace, brocade or raised figure effects, on such fabrics.
  • the cellulosic threads 30 may be removed by treating the iabric in a hot bath containing aluminium chloride,
  • the baths may contain the acidicsubstance in solution in water or in organic, liquids having no 4o deleterious effect upon the animal fibres or ,celluorganic solvent.
  • the acidic substancesI may be employed in solution in organic acids, for example acetic acid.
  • Local effects for example the localremoval oi pile or plush, may be obtained according 'tothe present invention by first applying tothe fabric consisting of or containing cotton or other cellulosic fibre'a suitable substance adapted to reserve the fibre against the action of the acidic substances.
  • the fabric is thereafter treated in a hot bath containing the acidicvsubstance only the cellulosic fibres in the unreserved portions will be disintegrated and rendered removparticularly vide' newor improved processes for thereinoval delustering, if
  • the acidic salts may be used. Moreoven with greater concentrations lower tem- 10 peratures or shorter timesmay be employed if desired.
  • the 16 the bath in treating materials containing cellulose acetate may be below the delusteringtemperature, or alternatively substances may be added to the baths toprevent such delustering, for example, sodium sulphate, or other 20 neutral salts or other salts or sugars, (see for example United States Patents Nos. 1,7 56,581 and According to a modification of -the invention,
  • the iabricsitreatedaccording to the present invention may be coloured in any desired man-
  • suitable colouring matters may be incorporated in the reserve; or again the reserved portions may be subsequently coloured.
  • Two. or 'multi-colour effects may be, obtained on mixed fabrics by taking advantage of thedifierent dyeing aillnities of the fibres used in association.
  • mordant metalsalt such as alumin- 40 aluminium sulphate-or ferric chloride
  • mordanting or the reserved fibres or of the fibres such as animal fibres or cellulose derivatives which are unattacked by themacidic'substances, then such mordanted flbresmay afterwards he coloured dyestufis, l i
  • Example 1 a mixed natural wool-cotton fabric is boiled as in an aqueous solution of hydrochloric acid of 2-3 per cent. strength for 2-3 hours or until the cotton fibre is readily removable, as for example by washing, brushing or the like.
  • Example 2 A mixed fabric containing cellulose acetate, natural wool and cotton is heated at C. in an aqueous solution of ferric chloride, containing 10 per cent. of Glaubers salt, of 3-5 per cent. concentration, for 2-3 hours or until the cotton is readily removable. After the removal of the cotton the fabric may be dyed with mordant dyestuffs .to fix therein an iron lake. 7
  • Example 3 reference numerals refer to similar parts
  • Figure 1 shows a fabric woven with natural silk yarns, I, in the warp and cotton or regenerated cellulose yarns, 2, in the weft.
  • Figure 2 shows the fabric of Figure 1 after certain portions, A, of the cotton or regenerated cellulose yarns have been-removed by the'local application of the hot acid locally.
  • Figure 3 shows a fabric woven with natural silk yarns, l, in the warp and cellulose acetate yarns, 3, in the weft.
  • Figure 4 showsthe fabric of Figure 3 after a certain portion, B, of the cellulose acetate yarns has been saponified by the local application of a saponifying agent, the saponified portions of the cellulose acetate yarn being shown at 4.
  • Figure 5 shows the fabric of Figure 4 with the saponified portion, B, of the cellulose acetate yarns removed by the hot acid treatment.
  • Process for the production of effects upon fabrics which consists in subjecting mixed materials oontaining fibres comprising cellulose acetate at least in selected areas to the action of a reagent which will saponify the cellulose acetate, then treating the materials in a hot bath containing ferric chloride until the cellulosic fibres are rendered removable by the action of said bath and mechanically removing thesame.
