means of which there is produced a clear white in
cotton without any deterioration of the more. The
material TO DO bleachcd 10 treated in a starcnirg
machine with q lyo to which bisulphite OF soda and
an alkaline chloride have been added. ana the goods
are then subjected to a very heavy pressure; from
this stiIening machine they are transferred to .
81, aiming apparatus, In which they remain some
thirty to sixty minutes. according to the nature OF
the goods, and this treatment In the SCANNING ap.

The other operations of the bleaching process are
OF the ordinary kind. The addition OF the alkaline
chloride to tas iyc promotes solution of ine gumny
matter and capsuiei in the nbre; and the compost.
