rnoonss or DYEme ARTIFICIAL SILK.
No Drawing. Application filed April 2, 1927, Serial No."1B 0,611, and in Great Britain June 7, 1926.
This invention relates to dyeing and is an improvement in or a modification of the invention described in our copending application No. 180,610, filed April 2, 1927, according to which we have discovered that the secondary disazo dyestuils obtained by coupling aminosalicylic acids or their homologues, hereafter referred to as amino-ohydroxy-carboxy acids of the benzene series, with the usual middle components, further diazotizing and combining with the peri-substituted naphthalene sulpho acids as end-components, have a good aiiinity -for regenerated cellulose silks and possess the valuable property of giving level dyeings on these fibres.
We have now found that in addition to the said disubstituted naphthalene sulpho acid components used in our previous application there may be used as end components coupling components of the naphthalene series containing a single auxochromic group, namely naphthols, naphthylamines and their N-su lostitution products, and sulphonated derivatives of these classes. The present invention consists in the dyeing of regenerated silks, such as viscose silk, with the secondary disazo dyestuii obtained by combining amino-o-hydroxy-carboXy acids of the benzene series with the usual middle components, further diazotizing and combining with a coupling ofthe naphthalene series, namely a naphthol, or a naphthylamine or an N-sul; stitution product or the latter, or with a sulphonated derivative of one of these. As middle components there may be used a-naphthylamine, 1-amino-2- naphthol ether-s, l-naphthylamine-B- or 7- sulphonic acids, 1amino-2-alkoXy-naphthalene-6- or 7-sulphonic acids, meta-aminopa-ra-cresol methyl ether, amino-hydroquinone-dimethyl ether and the like.
The dyestuffs so obtained have a wide range oi shades according to the end component chosen, and they give level dyeings on regenerated cellulose silks. Some of these dyestuffs are already known and have been used for dyeing wool, particularly for producing blacks by after-treatment with chromium compounds, but it was not foreseen that they would have a good afinity for regenerated cellulose silks and that they would give level dyeings on these fibres.
The fibres are dyed in the usual way, the
following description being typical, but we do "not limit ourselves to the conditions quoted (the parts are by weight) The dyebath is made up from 3000 parts of water, 20 parts of Glaubers salt, 2 parts of soap and one part of solochrome black F (Colour Index No. 299). 100 parts of the regenerated cellulose silk are entered into the bath at about C. The bath is then heated to about C. and dyeing allowed to proceed for about one hour. The silk is then removed, rinsed and dried. The resulting dyeing is a level deep black shade. By after-treating the dyed fabric with chromium fluoride the tastness to. washing is considerably increased.

What weclaim and desire to secure by Letters Patentis l. The dyeing process which comprises dyeing regenerated cellulose silks with secondary disazo dyestuffs made by combining amino-o-hydroXy-carboXy-acids of the benzene series with the usual middle components, further diazotizing and combining with a coupling component of the naphthalene series containing a single auxochromic group H 2.
