Description
Fetenteel Oct. 6, 193i IVOE MORGAII J AND WILLIAM. 'ZZIJBY, C-F LANCASTER, ENGLAND, ASSIGNORSTG SCGTTISH DYES, LIMITEDfOF GRANGEMOUTH, SCOTLAND DYEING AND PRINTING No Drawing". Application filed June 27, 1927, $eria1 No. 201,959, and in Great Britain June 28, 1926.
'5 connection with these processes.
The invention consists in a process for the production of dyed products by means of soluble ester derivatives of reduced vat dye-V stufis which eliminate the use of vats according to which process dyeing is effected by padding and the material is steamed without drying after the padding process, the steamed material being subsequently entered into a development bath.
The invention also consists in a process which comprises the padding of soluble ester derivatives of leuco vat dyestuffs on to textile fibres, particularly such derivatives as M may be prepared by processes of the kind in dicated in the specifications referred to above, together with an oxidizing agent which is substantially inactive under the conditions of steaming,then freeing the padded goods from superfluous liquor and Without drying, steaming the goods, treating them in a developing bath, rinsing and, if desired, soaping.
The invention also consists in a modification of the process according to the preceding paragraph in which an acid oxidizing agent is added to the developing bath instead of to the padding bath.
The invention further consists in a process as indicated in any of the preceding three paragraphs which includes the employment in the process of emulsifying or dispersing agents such as soluble oil or the like, soda ash or other weak alkali or Monopole soap, either as an addition to the padding liquor or by treating therewith clothor the is tobe padded.
The invention further consists in processes for the dyeing of materials substantially as hereinafter described and in dyed products when prepared by those processes or by the obvious chemical equivalents thereof.
The following examples illustrate how the invention may be carried into effect, all parts being parts by Weight:
like which Ewample 1 The'cloth is padded on a padding mangle at 95 C. with a solution made as follows Parts by weight Soledon jade green (commercial paste) 105 Sodium nitrite; 1 6% gum dragon;thickening i 8 Soluble oil 1 Water to 100 After removal ofsuperfiuous liquor it is then steamed without drying for 10 minutes in an ordinary Mather & Platt steamer, and developed in an open width soaping machine by passing through 1 per cent. sulphuric acid, then rinsing and soaping.
I E sample 2 The cloth is padded on a padding mangle at 95 C. with a solution made up as follows':
Parts by weight Soledon yellow; 10 6 gum dragon thickening 8 Soda ash 1 Water up to 100 It is then steamed without drying for 10 minutes in an ordinary Mather & Platt steamer and'developed in an open width soaps ing machine bypassing through 1 per cent. sulphuric acid containing 1 per cent. of hi chromate of soda at 7 0 C. then rinsing and soaping. I a
Eazcmtple 3 The cloth is padded on a padding mangle at 85 C. with a solution made as follows Parts by weight Indi 'osol pink HR 5 6% gum dragon thickening 5 Soluble Oll 2 Sodium nitrite 1 ater to 100 It is finally treated as in Example 1.
Example 4 The cloth is padded on a padding mangle at C. wlth a solution made up of Parts by weight Indigosol O l-B 5 6% gum dragon thickening 5 Soluble oil 2 Sodium nitrite 1 ater up to 100 The cloth is then steamed without drying and developed as in Example 1.
Example 5 Dyestuflf paste.-. 50, 10 200. 300, Soluble oil 7.5, 10. 12.5. 15, Sodium 111' e- 10, 1O, 10, 10, 0% gum d on thick 111g 8, 8, S. 8, S, 8 parts Watcrto n 1000, 1000, 1000, 1000, 1000, 1000 The cloth is then steamed without drying and the colour develoned as in Exam )le 1.
General Since the products referred to as used for dyeing are comparatively new thetollowing information is given concerning them (a) Soledon jade green (Scottish Dyes, Limited) appears to be a sodium salt of a sulphuric acid ester prepared from Caledon jade green (colour index 1101.)
(Z2) Soledon yellow (Scottish Dyes, Limited) is apparently the sodium salt of a sulphuric acid ester prepared from Caledon yellow G. (colour index 1118.)
(0) Indigosol pink HR. (Durand and Huguenin) is probably a sulphuric acid ester prepared from Helindone pink R. (colour index, commercial name index).
((Z) Indigosol 4B (Durand and Huguenin) is probably the disulphuric acid ester of indigo MLB/lB. (colour index 1184).
Having now described our invent-ion, what we claim as new and desire to secure by Letters Patent is 1. The process which comprises the padding of: soluble ester derivatives of leuco vat dyestuffs onto textile fibres together with an oxidizing agent which is substantially in active under the conditions of steaming, then freeing the padded goods from superl'luous liquor and nez; without drying, steaming "the goods subsequently treating them in a developing bath and rinsing.
:2. A process for the production of dyed products by means of soluble ester derivativcs of reduced vat dyestuffs which eliminate the use of vats which consists in padding the aforesaid derivatives on to the material to be dyed, steaming the material without an intermediate drying stage and subsequently developing the colour on the steamed material.
3. A process as claimed in claim 2 which consists in carrying into ei'l ect the padding process in the presence or a dispersing agent.
In testimony whereoi we have signed our names to this specification.
