摘要:
Denim having a stone washed appearance is produced without stones by treating with a cellulase enzyme. Unsewn dyed denim fabric or a newly manufactured garment made of dyed denim fabric is contacted with an aqueous composition containing at least about 2500 CMCS units of cellulase per liter, and subjected to mechanical action. Preferably, the aqueous composition provides at least about 6000 CMC units of cellulase per pound of unsewn fabric or garment. The aqueous may also contain an electrolyte, a buffer, a builder salt a cellulase activator, an antioxidant and a solubilizer.

摘要:
A process for transfer printing onto solid substrates made of plastics or having a surface layer of varnish or plastic is described. According to the invention described a sheet dye carrier at a temperature suitable for dye transfer is pressed to a preferably preheated surface and/or to a limited area of the surface to be printed by means of superatmospheric gas pressure, in particular by means of a flowing gas. Additionally the surface to be printed is maintained at a temperature below the thermoplastic range during the transfer process.
