Description

Patented July 2, 1940 TEXTILE AND OTHER. MATERIALS I Ienry Dreyfus, London, England No Drawing. Application May 5, ---No. 140,897. In Great Britain May 10 Claims.
This invention relates to textile and other products containing titanium dioxide and to an improved form of titanium dioxide particularly suitable for incorporation in artificial silks and 5 other artificial products, for example films, moulded objects and the like.
Artificial silk having a low lustre is extensively manufactured with the aid of titanium dioxide. A small proportion of this material is incorl porated in the spinning solution from which the artificial silk is formed. Another method of producing an artificial silk of low lustre is to incorporate titanium dioxide or hydrated titanium dioxide in the already spun artificial silk, e. g. by 1 interaction of suitable reagents on the material,
or by treating the material with an aqueous dispersion of titanium dioxide. however, that when artificial silks containing titanium dioxide are coloured the colourations are U in general not so fast to light as those yielded by the same dyestufis upon similar materials free from titanium dioxide. This lack of fastness'to light is particularly noticeable while the material is wet. Further, artificial silk containing 2! titanium dioxide frequently loses strength much more rapidly when exposed to light than similar artificial silk free from titanium dioxide.
According to the present invention these undesirable effects of titanium dioxide are minimized 30 by associating or treating it with a compound of manganese, iron, cobalt, nickel or copper. These elements are those having atomic weights ranging from that of manganese to that of copper. The titanium dioxide may be treated with the 35 metal compound or a mixture of the metal compounds before the titanium dioxide is incorporated in the artificial silk or other material. Again, the artificial silk or other material containing the titanium dioxide may be treated 40 with the metal compound or a mixture of the metal compounds and either before, during, or after any colouring of the material.
If desired, the treatment of a textile or other product with the metal compound may precede 45 or be carried out simultaneously with the incorporation of titanium dioxide in the material or as a step in a process of effecting such incorporation. Moreover,,a cellulose ester or other substance may be treated with the metal compound 50 prior to conversion into filaments, e. g. while in the form of a spinning or film-forming solution,
and before or after, incorporation of titanium dioxide therewith.
Conveniently water-soluble compounds of the 55 metals are employed and they maybe salts of It has been found,
1937, Serial 14, 1936 the metals with acids or they may be compounds in whichthe metal forms part of an anion. Examples of suitable salts are the sulphates, chlorides, or acetates of the aforementioned metals. The treatment or association of the titanium dioxide with the metal compound is applicable in the case of natural textile fibres containing titanium dioxide, for example natural silk, in which titanium dioxide has been incorporated. It is, however, of special value in the case of artificial silk and other artificial products containing titanium dioxide. For example, the new process may be applied in the case of regenerated cellulose artificial silk, foils, or films containing titanium dioxide, or artificial silk, films, foils,
plastics and the like containing titanium dioxide and having a basis of cellulose acetate or other cellulose ester or ether.
The titanium dioxide or material containing it may be treated with an aqueous solution containing one or more of the aforementioned compounds. For example, titanium dioxide sufliciently finely sub-divided to render it suitable for incorporation in an artificial silk spinning solution may be heated or boiled with a 0.1 to 5%, e. g. 0.3 to 0.5%,aqueous solution of copper sulphate or other of the metal compounds referred to above. Again, a textile material, for example an artificial silk containing titanium dioxide, may be heated with a dilute aqueous solution of copper sulphate or other of the above-mentioned metal compounds. Such a solution may, for example contain .05 to 1% of the copper sulphate or other compound.
If desired the solutions of the metal compounds may contain an acid, for example formic acid, acetic acid, or other organic acid. The amount of acid used may be about half the weight of the metal salt.
When treating textile materials, foils, or the like containing titanium dioxide, the treatment liquid may contain a swelling agent for the cellulose acetate or other material forming the basis of the textile, foil or the like, in order to facilitate penetration of the material by the treatment liquid.
After treatment with the aqueous solution the titanium dioxide or material containing it may be washed. The material may then be dried,'or further processed without drying, as may be convenient. For example, in the case of a textile material containing titanium dioxide, the wet material maybe dyed without intermediate drying.
If desired the titanium dioxide or other material may be subjected to a treatment to ensure Y theflxation of an oxide, hydroxide, or other wa- 'ter insoluble compound of the metal in the materiaL, For example suitable reagents may be allowed to interactin the presence of the titanium dioxide so as to form an oxide or hydroxide 0f the metal on the titanium dioxide. For instance finely divided titanium dioxide may be heated with an aqueous solution of a salt oi. one
of the aforementioned metals and an aqueous solution of an alkali slowly added in sumcient quantity to precipitate an oxide or hydroxide of the metal on the titanium dioxide.
Other methods of associating with-the titanium dioxide a compound or compounds of the manganese or other metal may, howevenbe employed. For example the titanium dioxide may merely be intimately mixed with the compound of the metal in question. For instance an aqueous paste of titanium dioxide may be well ground with an aqueous paste of an oxide or hydroxide of the manganese, copper or other metal, the mixture being thereafter dried if desired.
The compound of manganese, copper or other metal may be employed in quite small proportion, for example a proportion of the order of .05 to 5%, e. g. .5 to 2%, based on the weight of the titanium dioxide.
The new process enables improved results as regards fastness to light to be obtained when materials containing titanium dioxide are coloured with dyestuffs of widely varying type. For example the improvement is particularly good in Y the case of water-soluble azo dyestufls having a 85 substantive aflinity for regenerated cellulose. Again, the dyestufis may be azo dyes, soluble or insoluble in water, having a direct aillnity for cellulose acetate. Other classes of dyes the colourations "of which on textile materials contain- 'ing titanium dioxide may be improved by the new process are the amino-anthraquinone dyestuffs having direct afilnity for cellulose acetate, especially those dyestuffs yielding violet, blue or green shades on this material. The improvement is particularly good in the case of dyeings made with 1.4-diamino-anthraquinone or L-i-amino-oxyanthraquinone and their substitution products, for example 1.4-di-(alkylamino) -anthraqulnone. 'An improvement may be obtained even in the case of those dyestuffs normally regarded as having a very high degree of fastness, for example vat dyestuffs, e. g. those of the indigoid series,
and the water-insoluble azo dyestufl's produced on the fibre, for example those produced by coupling diazotised amines with p-naphthol, arylamides of 2:3-oxy-naphthoic acid, or diacyl-acetyl derivatives of aromatic diamines.
The following examples illustrate the invention but are not to be regarded as limiting it in any way:
Example 1 Finely divided titanium dioxide is heated for 30 minutes at 85 to 90 C. with 20 times its weight of an aqueous solution containing 4 grams per litre of copper sulphate and 1.5 grams per litre of formic acid. The titanium dioxide is then filtered oil, washed and dried.
For the production of artificial silk 0! low lustre 2 parts of titanium dioxide treated as above are incorporated in 400 parts of a 25% solution of cellulose acetate in acetone and the solution thereafter spun into filaments by dry spinning 'methods. Shades yielded on this artificial silk 7| with, for example, 1.4-di-(methylamino)-anthra-' treated titanium dioxide,
The copper sulphate in this example may be replaced by an equalv quantity of manganese 5 sulphate (MnSO4) cobaltssulphate or nickel sulphate.
Example? A fabric of cellulose acetate yarns having a 10 low lustre due to the presence of titanium dioxide therein is treated for one hour at C. with an aqueous solution containing .5% or copper sulphate and .2% ct formic acid. The material is well washed and is then dyed with 1.4-di- (methw ylamiriohanthraquinone. In this way a blue shade is obtained which is much faster to light than that obtained when the treatment with copper sulphate is omitted. j
The copper sulphate in this example may be 20 replaced by an equal quantity of nickel sulphate or cobalt sulphate or manganese sulphate (M31304).
