摘要:
By the use of a known bacterial .alpha.-amylase having significant activity at pH values above 8.5 and temperatures below 30.degree. C., de-sizing and reactive dyeing by the cold dwell process may be carried out simultaneously on cellulose textile materials. The dyed materials have good color yield and levelness and are not hardened.
