tiseiul Process for lfnguinining and Dyeing Raw Natural Silk, of which the following is a full, clear, and exact specification.
l have found that natural silk, naturalsilk waste, and yarns and tissues of natural silk or of natural-silk waste gurnrned and dyed simultaneously by the same operation when the said raw silk is treated during aconvenient time with the lather of a soapy dyeing-bath in the presence of air and steam and afterward submitted to I a single washing.
For ungumining and dyeing, for example, one hundred kilograms o'l' raw-silk hanks I proceed as follows: In the upper part of a not tightly-elosed vessel--for 0/ of the apparatus shown in the annexed drawing-containin about five hundred and eightyliters oil water in which about thirty-three kilograms of soap and about live kilograms of a rhodaniine dyestuif have been dissolved the silk hanks are suspended or laid in oonvenient holders-as, for instance, the sieves b of the annexed drawing-An such manner that the liquid c or" the vessel may not at any rate come into contact with the silk hanks. he soapy dyeing-bath oi the vessel is then heated by steam or otherwisefor instance, by the serpentine )ipe d of the annexed drawing to the boiling-noint in order to transform it in lather which will rise in the vessel along the hanks contained therein and envelop the latter at all parts, so that the said hanks will be. subjected to the combined action of steam, hot air, and lather of the soapy dyeing-bath, the elleet of which will be to soften and render permeable the gunnning envelop (sericine envelop) of the silk, so that the. dyest'vu'll' oi the lather may penetrate to the inner ilbroin of the silk and be fixed by the said libroin alter twenty to iifty minutes. The hanks are then removed with their holders from the vessel and washed in water, whereby the softened sericine is eompletely or only partly removed from the. libroin.
The transformation or the soapy dyeingbath in lather may be aided by injecting air Specification of Letters Patent.

To the soapy dyeing-bath sulrstanees--as, for instance, substances containing tannin, as eateehu, divi-divi, sumac, &c., metallic salts, as tin salts, lead salts. anl tiinony salts, AteQ-flnay be added in order l charge also the silk with these substances during the ungunnning and dyeing process.
/Vhat 1 claim is instance, ie pipe 6, supplied l l. The herein-deserihed process for ungumining and dyeing silk simultaneously, l consisting in first making a bath containing soa and a. dye, then treating the raw silk 1 with lather or" the said bath in presenee steam and air, and finally washing the silk i thus treated. l 2.

3. The herein-desorilmd process for ungunnning and dyeinf silk simultaneously, consisting in first niaring a bath containing soap and a dye, then. treating the raw silk with lather of the said bath, obtained by heating the said soapy dyeing-bath to the boiling-point and by injecting air in thesaid soapy dyeingdiath, and finally washing the silk: thus treated.
