Application for reissue filed November 28, 1924.
To all who"; it may] concern.
Be it known that I. JosErH SEYER, a citizen of the United States, and a resident of Hawthorne, county of Passaic, and State of New Jersey, have invented certain new and useful lVashuble Dyed Silk Piece Goods and Processes of Dyeing Them, of which the following is a specification.
This invention relates to a new article of manufacture or product consisting of a washable silk fabric which has been dyed in the form of piece goods, and the processes of producing and dyeing such fabrics.
Hitherto no successful way has been found of dyeing silk piece goods in various colors so as to produce a washable article, that is,
one that may be washed in warm soap water without losing its color or without becoming spotted or irregularly changed in its shade of color. My invention has succeeded in producing silks dyed in various colors in the form of piece goods, and it has furthermore achieved the production of washable silks which will not impart their colors to a washing liquid such as an aqueous soap solution. My invention has accordingly as an object the production of washable silks dyed in any desired shade of color in the form of piece goods, and it has as a further object the production of washable silks which will not impart color to the Washing liquid. It is also an object of my invention to produce washable silks dyed withcolors of many kinds and shades that are relatively inexpensive, and to fix these colors on the silks.
A further object is to avoid the uneven dyeing and undesirable results obtained by mordanting silk previous to the beginning of the dyeing operation. A still further object is to produce piece goods of silk which will be'relatively fast to perspiration, light, and ironin t is also an object to produce the a ove results with pure silk and also with mixed goods.
Further ob'ects will appear hereinafter.
In the preierred embodiment of my invention I proceed by four difi'erent processes according to whatever color and shade is desired, each process var ing more or less from the other in certain etails. I shall there- Serial No. 752.826.
Process #1.
This process, to be described below, is applicable for the following colors:
White Cream Leghorn S. 1001 S. 1045 S. 4115 Apricot Ashes of roses Chartreuse S. 4123 S. 2173 S. 5413 Flesh Pink 2 Pink 3 S. 2131 S. 2105 S. 2107 lle green Lt. blue 2 Lt. blue 3 S. 5143 S. 6105 S. 6107 Champagne Fawn S. 4183 S. 3185 Orchid Reseda Burnt orange Terra cotta S. 3025 S. 4285 Maize S. 3115 Salmon pink S 2145 Ivory S. 1041 Ocean green 8. 5164 Pink 1 Lt. blue 1 S. 6103 Beige S.

Honey S. 4135 Horizon S. 1683 Iris Mermaid S. 1583 Coral S. 2133 Lt. blue 5 Pink 4 S. 6161 S. 2108 The process is conducted as follows: The piece goods are treated in a continuously boiling bath containing 250 ga lons of water,
Blossom S. 1223 10 l s. sodium phosphate (Na,HPO,12H,O),
one lb. strength Turkey-red oil (alkaline), one gal. 50% soap solution, and the goods are worked therein for 20 minutes, after which are added to the bath 20 lbs. Glaubers salts (Na,SO,,.1OH O) and a dyestutl' such as a direct, basic, vat, or sul r d e according to whatever shade is desired. *xamples of these dyes are iven below). The 'ljgrkey-red oil has a mor anting action havingihg effect of fixing the dye. or color on the goods under the conditions of the described operation.The goods are then given a cleansing soap bath at a boiling temperature and the goods are worked for 30 minutes. They are then washed well and acidulated. This method is applicable generally to light shades but may be used or other colors also.
Process #2.
This process is applicable for the following colors:
Turquoise Geranium Beaver Strawberry Emerald S. 6l53 S. 2035 S. 3l87 S. 2185 S. 5005 Hunter Myrtle axe blue Electric -apphire S. 5(1)? S. 5067 S. 6053 S. 6055 S. 6057 Plum Prune Eggplant Copenhagen Dcllt S. 7187 S. 7817 S. 7905 S. 6183 x. 6155 Slate Graphite Smoke Taupe (astor S. 8067 S. 8965 S. 8935 S. 8845 S. 8843 Raspberry National Yale blue Marine Cadet S. 2165 S. 6005 S. 6007 S. 6083 S. 6853 Regimental Olive Evergreen Cherry Ruby 8. 6855 S. 5485 5499 S. 2063 S. 2065 Am. Beauty Peacock Wisteria Magenta Fuchsia S. 2067 6505 S. 7195 S. 7285 S. 7205 Bottle green Violet Pansy Purple Old china S. 5827 S. 7003 S. 7005 S 7007 S. 6184 Japan blue Moss (armine Bluebird Spring green 5. 6187 5483 S. 2263 S. 6(155 S. 5043 Indiana The process is conducted as fol'ows: The piece goods are dyed in a. cum soap liquor. otherwise known as boiled off liquor, acidulated with 2 lbs. 66 Be. and 20 lbs. respectively of sulfuric or acetic acid, and the operation is begun by working the goods in this bath for 20 minutes. after which the dyestuffs such as basic. direct or acid dyes are added to produce the shade desired as above. lVhen the goods match the objective sample. there are added to the dye bath of 250 rallons liquor. 5 lbs. tannic acid gC H aflH Ol and the goods are worked or one hour continuously at a boil. They are then we'l washed an treated in a cold bath of water comprising two hundred and fifty gallons. with 4 lbs. tartar emetic (C H O KSbOJ/ H O) for 40 minutes. After this they are well washed and then cleaned in a soap bath at 160 F. The treatment is now concluded by washing well and acidulating.
Process #3.
Brown S. 3295 Navy 1 S. 6085 Tobacco S. 3945 Navy 2 Navy 3 S. 6925 S. 6975 Negro Olive brown S. 3948 S. 4856 The process is conducted as follows: The piece goods are dyed in a boiling water liquor or in a. guru soap liquor. acidulated with (per 250 gallons liquor) 20 lbs. acetic acid. using direct dyes according to the shade desired. and continuing the boiling treatment until the goods are dyed to the desired shade. They are then treated with about six pounds of tannic acid in a. water liquor comprising about two hundred and fifty gallons of liquor. at a temperature of 160 F. for one hour. They are then washed well and treated in a cold water bath of two hundred and fifty ga'lons with 4.5 lbs. tartar emetic for 40 minutes. after which they are again well washed. A diazotization is then carried out with 5 lbs. sodium nitrate (NaNO in cold water comprising two hundred and fifty gallons containing 2 lbs.
Navy 4 S. 6985 sulfuric acid per 250 gallons of liquor. This diazotization. which lasts '20 minutes. is followed by washing well and developing in 2'10 ralons of cold water with 33 lbs. sodium carbonate ua conorno). A cleansing treatment with a soap solution at 160 F. for l0 minutes follows and the goods are then washed well and acidulated.
Process #4.
This process is applicable for the following colors and is used with diazotizable dyes:
Scarlet Cardinal Dk. cardinal Garnet Claret S. 2003 2005 S. 2007 S. 2009 S. 2167 Burgundy Maroon The process is conducted as follows: Thrpicce goods are dyed in a boiling water bath with a diazotizab'e dye such as a liquor with primuline dye, and the goods are dyed therein to the required shade. and then diazotized with 5 lbs. sodium nitrate and 2 lbs. sulfuric acid in 250 gallons of cold water for 20 minutes. They are then washed well and developed with 6 lbs. beta naphthol in 250 gallons cold water. worked well for 40 minutes. and then washed. At this point the treatment is continued according: to process #1, beginning at the first step thereof. for the purpose of dyeing to the shade desired with basic or direct dyes. The goods as finally dyed are given a cleansing bath of soap water at a boiling temperature and worked for 40 minutes. then washed and acidulated, substantially as in the final step of said process #1.
In the four above-described processes various classes of dyes are mentioned for use in the respective processes, and it is desired to state here some exampes of the dyes falling under each class. As basic dyes may be used brilliant green, Victoria blue. rhodamine (red). thioflavine T (yellow). and methyl violet 6 B (blue) and 5 R (red) as direct dyes, pontamine green BBX diazoline dark brown. accordine seal brown; as acid dyes. fast red, milling yellow. formy'. violet, formyl blue. nigroslne; as vat dyes. argole blue 3 G, helindone red. helindone violet, and substantially all of thc other vat dyes; as sulfur dyes, sulfur yellow. sulfur blue. sulfur brown. and suhstantia'ly all of the other sulfur dyes. This list is illustrative. not exhaustive, as other dyes may be used according to their nature and shade.
For producing a black I roceed as follows: The piece goods are (yed in a. bath composed of 500 gallons of water. 30? by weight of fustic extract, 10% by weight of hematine extract (oxidized logwood). The goods are worked in the liquor at the boiling temperature for 20 minutes, and then to the same liquor are added 25% CATlON OF TEXTILES (it H8 ERS,
by weight of black iron. 4? by weight of b He stone. and 20% by weight acetic acid (to dissolve precipitate in the bath). The goods are worked at the boiling temperature for one hour. and are then washed well. The goods are now treated in another bath composed of 500 gallons boiling water. 3054; hematine extract. and 50 lbs. soap, and they are worked therein for one hour, and then washed. The next step consists in treating the goods in a bath of 500 gallons water at 160 F., containing tannic acid in the proportion of six pounds tannic acid per 250 gallons of dye liquor. This is followed by the tartar emetic treatment as in process #3, namely, four and one-half pounds of tartar emetic per two hundred and fifty gallons of dye iquor. The final dyed goods are given two cleansing soap baths at a boiling temperature. and then washed well and acidulated. There is thus produced a washable black which will not impart a black or dark color to a washing soap liquid below 160 F. or thereabouts.
As a result of the above processes there are produced varieties of dyed silk piece goods which are washable, that is, they may be washed in water containing soap at a temperature of F. and they will. in most cases, stand 180 F. or higher. without sut fering unevenness in shade or color, or distinct loss of color. In addition to the highly desirable quality of being washable. these piece silks have also the property of being washable without imparting any substantial amout of their color to the washing liquid. such as water or soap solution. They are also dyed evenly. that is, without irregularity in the color or unevenness of shade. These results have not hitherto been achieved with silk piece goods, and I have not only been able to attain these results in certain colors, but have been able to extend them to all colors and shades thereof. The alizarin dyes, which are used for the production of fast colors in skein silk. are expensive and exist only in a limited number of shades. My new silk goods may accordingly be distinguished from other silk goods by noting several of their qualities as follows: They have been dyed in the piece. and are fast to washing in In ewarm soapy water (about 110 F.) but not fast to boiling soapy Water although. as before stated. they may often stand higher temperatures than 110 R. up to about F., or higher. Another feature of my new goods is that they may be produced and sold in all colors and shades of color. My piece-dyed silks are dyed to an even color and will not lose this evenness of color by subsequent washing. still further characteristic of my silk piece goods is that they will not bleed in cold water, that is, impart color thereto, nor will they readily show the marks and efiects of perspiration. They may be washed together with silk. cotton. artificial silk. wool. etc.. without staining them. the temperature being about 110 I as above. They also have excellent fastncss to light and ironing. the case of process No. 1. they will have the characteristic of being free from metallic mordants.
\Vhile my silk piece goods have been derribcd as being of umuixed ilk. it is also possible to make mixed silk goods such as silk and cotton. by the above-described proccsses according to the nature of the result desired.
In methods 1 to 4 inclusive I have described processes of dyeing silk in various colors. and in method 5 I have described the process of dyeing black. so that by the use of the words colored silk. or their equivalent. I mean colors other than black.
