Berlin Germany A METHOD FOR PRODUCING A LINT FROM NEW FLAX FIBRES
(A Communication from Moritz Salomonson of Bielefeld in the German Empire)
According to this invention a lint for dressing wounds is produced directly from
the new flax fibre. For this purpose the flax after being dried is broken, winnowed
and carded so as to be free from woody parts; it is then treated in a closed boiler
by two or three atmospheres pressure in a lye containing 6 per cent of 95 degrees
calcined soda as well as five per cent of a composition consisting of 1/, of potash and
the other */ of equal parts of pure oleine tallow and olive oil
The fibres are boiled about three hours in this lye and then well rinsed out to
remove the lye. They are then put into a chlor bath heated to about 60 to 68° F
for giving them a preliminary bleaching, then rinsed and wrung out, then put into
a muriatic acid solution, the acid then rinsed out, then wrung out and then placed
on the bleaching lawn.
In order lastly to fully soften the fibres which is very desirable, they are boiled
by half an atmospheres pressure in a solution of five per cent of the aforesaid
saponified fatty composition. The fibres are then rinsed out, dried, torn apart and
put through a carding engine in order to convert them into a soft fine cotton wool
like lint.
The carbonizing of the lint is effected after the last rinsing, and drying by
placing it in a carbolic acid solution, wringing it out and then spreading it out
to dry.
