Definitions

  • the fabric to bef bleached should be trayersed by the bleaching maximin as copiously and uniformly as possible and freed from air at a high boiling temperature, while the fabric must not be subjected to too severe treatment; It is also desirable to econou'iize in the use of boiling lyeysteain, labor and cost of manufacture and to simplify v construction and working. The efficiency of such a plant 1s considerably increased if there is a possibility of quickly heating-up the fabric to be treated and such quick heating-up 1s possible only if the fabric is sufficiently penetrated by the bleaching medium from the beginning.
  • the heating up and the penetration have therefore a mutual and assisting reaction upon each other because the permeability of the fabric to be boiled'is low at low temperature and pro ssive increases with increasing tem- "or increasingthe temperature will en- 40 able the lye to penetrate'the fabric more rapidly and more copiously as the fabric is trayersed by the lye.

  • the straining top 6? is likewise arranged a certain distance away from the solid cover 5.. They allow a uniform entry and exit of the lye to and from the'whole of the fabric to be bleached, and they prevent the orifices of the branches 11 from being stopped up. In the case where fabrics spread 'out i. 0., not in the hank, are to be placedinto-the baskets 3 and 4 through an opening in the side wall thereof,,when the baskets are outside the boiler 2 and rest on their sidewall.

  • the fabric to be bleached will oppose the greatest resistance to the passing through of the lye in the boiler 1 and will act in the manner of a plug. In consequence, pressure is produced in the lye below the fabric. As soon as this pressure reaches a certain amount which may be predetermined, the lower valve 12 will automatically come into operationso as to' allow surplus lye to pass from boiler 1 into the pip'e'25 and outer boiler 2. g
