  • Patent number: 5196030
    Abstract: In a process for transfer pattern printing of a moist textile web consisting wholly or predominantly of natural fibers, in particular cotton, and/or artificial fibers on the basis of cellulose, the pattern carrier web is a web of paper or a paper-like material which carries a pre-printed pattern of a water soluble or dispersable dye. After wetting of the textile web to a carefully controlled moisture, the textile web is joined with the pattern carrier web and the joined webs are compressed at a suitable pressure so that the pattern can be transferred without using heat. The advantage is that it will be possible to avoid both heating and use of organic solvents. It is also possible to transfer a pattern to a colored textile web since the textile web may be wetted before hand with an aqueous dye solution or dispersion instead of undyed liquid.

  • Patent number: 5019131
    Abstract: A process for redyeing partially bleached fabric or garments to yield sharply-etched multicolored designs comprises the steps of:(a) dyeing the fabric, or purchasing a commercial garment, with a background first color;(b) gathering selected areas of the dyed fabric with ligatures to restrict access of further reagents;(c) bleaching the gathered background dyed to remove the first color from the areas outside the gathered areas; and(d) redyeing the bleached areas with a second color,whereby sharply defined multicolored patterns are formed having from about 0.2 mm to about 2 mm of white gap between each color.

  • Patent number: 4950301
    Abstract: A method of treating natural or synthetic polyamide or cellulosic textiles comprises applying an effective amount of an arylating agent, preferably to the dyebath. The arylating agent may be of a formula Ar--(X--Y).sub.n wherein Ar is an aromatic residue such as substituted or unsubstituted benzene or naphthalene ring; X is a bridging group such as --SO.sub.2, --CO-- or --NH--; Y is a reactive group; and n is 1 to 3. The arylating agent reduces fibre damage of natural polyamide fibres during dyeing and proves the degree of dye fibre reaction in dyeing of polyamide and cellulosic textiles to improve wet fastness. Furthermore, on cellulosic textiles, wet and dry wrinkle recovery properties are improved as is the yield of reactive dye fixation. On keratinous fibres shrink resistant and moth resistant properties are improved also. Certain novel arylating compounds are disclosed also.
