  • Cellulase composition for treating cellulose-containing textile material
    Patent number: 5874293
    Abstract: The present invention is directed to a new cellulase composition for treating and finishing cellulose-containing textiles. The improved properties of the cellulase composition are based on an elevated content of EGII endoglucanase type component in an otherwise complete cellulase composition. When the composition with elevated EGII contents is used improved color properties, increased lightness, improved visual appearance and reduced pilling tendencies are achieved. The strength properties of the textile materials are essentially unchanged as compared to previously used cellulase compositions.
    Type: Grant
    Filed: January 31, 1997
    Date of Patent: February 23, 1999
    Assignee: Rohm Enzyme Finland Oy
    Inventors: Arja Sisko Kaarina Miettinen-Oinonen, Minna Johanna Elovainio, Pirkko Liisa Suominen
  • Cellulase composition for biofinishing cellulose-containing textile materials
    Patent number: 5858767
    Abstract: The present invention is directed to a new cellulase composition for finishing of cellulose-containing textiles, especially cotton. The improved properties of the cellulase composition are based on an elevated content of CBHII cellobiohydrolase type component in an otherwise normal background cellulase composition. When the composition with elevated CBHII contents is used improved color properties, increased lightness, improved visual appearance and reduced pilling tendencies are achieved. The strength properties of the textile materials are essentially unchanged as compared to previously used cellulase compositions.
