Definitions

• the present invention relates to an improved textile oil and to an improved method of treating certain textile materials prior to dyeing. More particularly, the invention is concerned with an improved textile oil which affords effective lubrication in all textile processing operations and which may be readily removed by scouring prior to dyeing.
• the invention pertains to a mineral oil base textile oil which contains dissolved therein small amounts of. three non-ionizing components, to Wit a detergent, an emulsifying agent and a coupling agent, which have a synergistic effect on the solution stability, emulsion stability and scouring efficiency of the oil.
• textile oil of the invention has particular utility in the treatment of certain raw animal fibres, such as raw wool, containing substantial proportions of lime or other alkaline metal compounds reacting with anionic materials to form salts of low water solubility.
• the textile oils most commonly used heretofore are based on various fatty oils of animal or vegetable origin. These oils are rather expensive and readily oxidizable. Mineral oils which are superior with respect to availability and oxidtaion resistance cannot be used as such because they are diificult to remove from the finished textiles by conventional scouring with Water containing soap and soda ash.
• the calcium ions present in the raw wool react with the anions of sodium sulfonates and other soaps'of conventional Wool oils and with anions of the soaps of the scouring baths to form Water-insoluble soaps and salts. These insoluble compounds are adsorbed on the W001, forming a curd or scum which resists subsequent scouring and seriously interferes with the dyeing process. Similar complications arise when hard water is used in scouringall types of textiles treated WithiBXtlle oils containing constituents which ionize in aqueous solutions to yield anions formingwater-insoluble compounds with calcium or thelike.
• The, present invention-oven atent Thirdly, the oil must be easily removable by scouring I with distilled and hard water scouring baths.
• a mineral base textile oil which is substantially free of constituents ionizing in aqueous solutions to yield ions forming compounds of low water solubility with calcium or the like and which contains small proportions of three non-ionizing oil-soluble components acting as a detergent, an emulsifier and a coupling or stabilizing agent, respectively.
• These three non-ionizing components have a synergistic effect upon each other and the mineral oil base with respect to their oil solubility, the detergency and the emulsion stability of the finished textile oil.
• Compounds suitable as the detergent component of the textile oil of the invention are the polyglycol esters of unsaturated high molecular weightfatty acids having the general formula wherein R is an unsaturated aliphatic radical having 14-22 carbon atoms, more specifically 16-18 carbon atoms, n is an integer of from 2-6, more specifically 2-4, and x is an integer offrom about 5 to about 30, more specifically 5-15.
• R is the hydrocarbon radical of oleic acid
• 11 is 2 and x averages about 13.
• a product of this type is now on the market under the trade name Antarox Agent 377-AE (Chemical Developments of Canada Ltd.; General Dyestuif Corp. U. S. A.). These products are probably mixtures composed chiefly of the mono-ester with some di-ester present.
• a concentration of about 0.5-20 wt. percent, preferably about 5-15 Wt. percent, of this component, based on mineral oil, may be used.
• the emulsifier component of the textile oil of the invention is a polyether alcohol of the general formula wherein R is an aryl, aralkyl or saturated or unsaturated alkyl group having 10-20, more specifically 14-16, carbon atoms, n is an integer of 2-6, more specifically 2-4, and x is an integer averaging about 2-20, more specifically 2-6.
• the preferred-emulsifiers are alkyl-aryl polyether alcohols in which R is essentially nonyl phenyl, n is 2 and x averages about 4%.
• a product of this type is on the market under the trade name Triton X-45 (Rohm and Haas Co.) which is essentially an alkylated aryl polyetheralcohol having the general formula r of the latter.
• the coupling or stabilizing agent of the textile oil of the invention is an oil-soluble unsaturated fatty acid partial ester of a higher polyhydric alcohol of the type disclosed in the MacLaurin Patent No. 2,404,240.
• the preferred coupling agent of the invention is sorbitan mono-oleate which may be used in concentrations of about 1-10 wt. percent, preferably about 2-6 wt. percent, based on mineral oil.
• concentration of the coupling agent in the finished textile oil should likewise be substantially below that of the detergent component and should not exceed about 50% of the latter.
• the difierent textile oils were tested for their solution stability and emulsion stability as follows.
• the solution stability was tested, storing the freshly prepared samples in sealed glass bottles at room temperature and observing visually the degree of separation after 1, 7 and 30 days of storage.
• the emulsion stability was measured by adding 10 mls. of oil to 90 mls. of the proportion of about 0.05-2 wt. percent, preferably less 10 test water in a glass stoppered graduate, shaking for 1 than 1 Wt. percent, say about 0.5-0.8 wt. percent, of minute and then allowing the solution to standfor 24 water to the textile oil. Such small amounts of water hours.
• the number of mls. of oil or cream separating cooperate with the coupling agent in increasing the from the emulsion within this time was recorded.
• the compatibility of the other components with the mineral composition and properties of the oils tested are sumil b 15 marized in Table I below.

• Formulae B-9 and 3-10 show that a range of from 1.5-4.5 wt. percent of the emulsifier used forms stable solutions for given concentrations of the other ingredients. A stable solution was also formed when the concentration of the ingredients of Formulae B-l were doubled as shown in Formula B-2.
• Example II Two textile oils of the type of Formula B-l of Example I were prepared as described in Example I with the exception that the detergent of one oil was a polyglyeol ester of oleic acid containing moles of ethylene oxide per mole of acid (Antarox Agent 377-BK) and the detergent of the other, oil was a polyglycol ester of oleic acid containing 8 moles oiethylene oxide ,per mole of acid (Antarox Agent 377-LE).
