Description
Patented Apr. 24, 1934 F F l PATENT TREATMENT OF TEXTILE OR OTHER MATERIALS No Drawing. Application November 26, 1930, Serial No. 498,436. In Great Britain January 22 Claims.
This invention relates to the treatment of textile or other materials.
In the colouration of materials e. g. yarns, threads, fabrics or films, difficulty often occurs owingto the fact that dyestuffs and reagents may not readily penetrate the materials. This diihculty applies in particular to materials, such as those made of or containing cellulose derivatives, which exhibit a low degree of water absorption. An operation in which a ready penetration of a reagent into a material is especially important is the printing of materials, and the difficulty arising from lack of easy penetration is particularly noticeable in printing with white or coloured discharge pastes. In the case of these printing operations attempts have been made to get over the difiiculty by adding certain hydroxy bodies such as alcohol, phenol, or resorcinol to the printing paste, and improved results have been obtained.
It has now been found that para-dihydroxy compounds, especially those of the benzene series, or derivatives of these compounds are exceedingly valuable agents for aiding the penetration of dyestuffs and other reagents into textile and other materials. They have been found of especial value for use in preparations for the local application of colouring matters or discharges to materials made of or containing cellulose derivatives.
According to the present invention therefore, para-dihydroxy compounds and derivatives of para-dihydroxy compounds are employed as aids to penetration of colouring matters, discharges, or other reagents into textile and other materials, and especially into materials made of or containing cellulose derivatives.
As examples of compounds which may be employed in accordance with this invention, hydroquinone, 2:5 dihydroxy-toluene, and their mono alkyl or aryl ethers or halogen derivativesmay be mentioned. Any other desired assistants may be used, for example, anthraquinone or alcohol in printing. As has been stated, While these paradihydroxy compounds may be employed in assisting penetration of the dyestuii, when dyeing in a dye bath, they are especially valuable in the local application of colouring matter or discharges, more particularly in the production of white and coloured discharge or discharge resist effects. The discharges or discharge resists may be oxidation discharges, for example chlorate discharges, or reduction discharges, e. g. hydrosulphite or sulphoxylate discharges.
After printing or stcnciling with the paste or preparation containing the para-dihydroxy compound or derivative thereof drying may follow and the printed or stencilled materials may then be suitably aged or steamed, or further rinse-u, 6U soaped, and finished as desired.
The following examples, while in no way limiting the invention, illustrate the best methods known to us for carrying the invention into effect:-
Example 1 A cellulose acetate fabric dyed golden yellow by means of the dyestuff 4-chlor-2-nitro-4- methoxy-diphenylamine is printed with a paste having the following composition:-
Parts by weight Hydron pink FF paste 15 Gum arable 1/1 50 Water 12 Hydroquinone 1 Caustic soda 2 Hydrosulphite powder 3 Anthraquinone 2 8O Methylated spirits 5 Formosul 10 The fabric is then dried and aged until the I requisite degree of discharge is obtained, after which it is washed and subjected to an aftertreatment for'the oxidation of the vat colour.
Example 2 a A cellulose acetate fabric is dyed a medium shade of blue by first applying ortho-ethoxybenzeneazo-a-naphthylamine and then diazotizing and developing on the fibre with fl-oxynaphthoic acid. It is then prepared for printing as required and printed with a paste having the fol- 9r lowing composition:--
Parts by weight Hydron. orange R. F. paste 15 Gum arabic 1/1 50 10 Water 12 Hydroquinone l Caustic soda 2 Hydrosulphite powder 3 Methylated spirits 5 Anthraquinone 2 Formosul 10 The fabric is then dried and aged until the requisite degree of discharge is obtained.
Example 3 v A cellulose acetate fabric is dyed a dull. green by means of a mixture of 4-chlor-2-nitrol methoxy-diphenylamine and the compound obtained by coupling diazotized' 2:4-dinitro-6- 1 methoxy-1-amino-benzene with the product of Ciba scarlet G Colour Index No. 1228) Gum arabic 1/1 50 Water 12 Hydroquinone 1 Caustic soda 2 Hydrosulphite powder 3 Methylated spirits 5 Anthraquinone 2 Formosul The fabric is then dried and aged until the requisite degree of discharge has been obtained. While the invention has been described abovemore particularly with reference to the production of local colourations on cellulose acetate materials, it is also of great value in the treatment of materials containing other cellulose esters, e. g. cellulose formate, cellulose propionate, and cellulose butyrate, or containing cellulose ethers, for example methyl cellulose, ethyl cellulose and benzycellulose, and of materials containing cellulose derivatives in association with other fibres. It may also be usefully applied to the treatment of material. containing other fibres than derivatives of cellulose, e. g. materials containing natural silk.
