Definitions
- This invention relates to'the treatment of textile materials and more particularly to the lubrication, softening, and conditioning-of fibrous materials formed. from hydrophobic cellulose derivatives.
- compositions comprising vegetaother substances are chiefly employed as anti-static agents to avoid the generation of excessive static electricity which would make it exceedingly diflicult, if not impossible, to process the fibers. It is: also the accepted practice to incorportate a surface-active emulsifying material in'these compositions so thatitcan'be readily removed prior to dyeing fabrics which have been knitted or woven from the treated fibers. Another commonly employed constituent in such compositions is a softening.
- N-hydr'ocarbon-trimethylenediamine dioleate wherein the hydrocarbon group is a straight chain saturated or unsaturated hydrocarbon radical having from 14 to 18 carbon atoms or a mixture thereof, is a highly effective coupling agent for a water-soluble or water-dispersible anti-static agent and mineral oil in a yarn finish.
- the yarn finish contemplated by this invention con-.
- the dioleate coupling agent from 5 to 17 parts by weight of the dioleate coupling agent and from 50 to 90 parts. by Weightv of mineral oil. It. is preferred to add from 5 to 25 parts by weight of an emulsifier to the finish so that it canbe readily removed from the yarn by washing or scrubbing with an aqueous medium.
- the emulsifier is necessary for this purpose because the dioleate is substantially insoluble and non-dispersible in water.
- R is a straight chainliydrocarbon radical having,
- the diamines useful for the present'invention are prepared commercially in thefollowing manner:
- R is an aliphatic hydrocarbon radical containing; 7 to 17 carbonatoms and mixtures of the same.
- R an aliphatic hydrocarbon radical containing; 7 to 17 carbonatoms and mixtures of the same.
- R an aliphatic hydrocarbon radical containing; 7 to 17 carbonatoms and mixtures of the same.
- R -d-OH the acid or acids R -d-OH described above.
- the fatty acids derived from naturally occurring fats and oils provide a convenient source, e.g. those derived from tallow wherein comprises a mixture of acids havinga hydrocarbon chain length of 13 to 17 carbon atoms; in other words R is a mixture of aliphatic hydrocarbon radicals having 13 to 17 carbon atoms, or those derived from coconut oil wherein R is a mixture of aliphatic hydrocarbon radicals having8 to 18 carbon atoms.
- the individual acids, which may be used aswell are also commercially available; in this instance R is a single aliphatic hydrocarbon containing 8 to 17 carbon
- the dioleate described above effects the dispersion in mineral oil of water-soluble or water-dispersible compounds which are not oil-soluble or oil-dispersible and impart anti-static properties to fibrous materials which would otherwise tend to pick up excessive electrostatic charges when processed.
- Such compounds are well known in the yarn finish art as anti-static agents.
- a preferred group of anti-static agents are organic quinquevalent nitrogen compounds such as quaternary ammonium alkylsulfates having attached directly to the nitrogen atoms from 1 to 3 straight chain hydrocarbon radicals which have from 12 to 18 carbons and attached to the-remaining bonds of the nitrogen, alkyl radicals having from 1' to 5 carbon atoms and/or a monocyclic organic radical having five or six members in the ring structure of which the nitrogen atom may be a member.
- the alkyl-gro'up to which the sulfate group is attached has from 1' to 4 carbon atoms and the alkylsulfat'e group forms the nega: tive ion of' these compounds.
- Examples of these-preferredl anti-static agents are as follows: oleyl ethyl niorpholinium ethosulfate, cetyl ethyl morpholinium ethosulfate, oleyl methyl morpholinium methosulfate, cetyl methyl morpholinium methosulfate, lauryl methyl morpholinium methosulfate, lauryl ethyl morpholiniumethosulfate, oleyl diethyl imidazolinium .ethosulfate, cetyl diethyl imidazolinium ethosulfate, lauryl diethyl imidazolinium ethosulfate, ethyl oleyl hydroxyethyl imidazolinium ethosulfate, ethyl cetyl hydroxyethyl imidazolinium ethosulfate, ethyl lauryl hydroxyethyl imidazolinium ethosulfate, la
- Halogen containing anti-static agents having a chloride, bromide or iodide ion in place of the sulfate ion in any of the abovedescribed compounds, can be used also.
- corresponding phosphate compounds can be used.
- Examples of other anti-static agents which can be dispersed in'mineral oil with the dioleate are lauryl alcohol phosphate, the lauric amide of N-methyl gluca'mine, mannitol (or sorbitol), dilauryl phosphate, dicetyl phosphate, diethanolamine salt of lauryl phosphate, triethanolamine salt of cetyl phosphate, sodium salt of lauryl phosphate, oleyl alcohol phosphate, cyclohexylamine salt of lauryl sulfate, cyclohexylamine salt of cetyl sulfate, oleic amide of N-methyl glucamine, polyoxyethylene sorbitan mono-oleate, polyoxyethylene sorbitan mono-laurate, polyoxyethylene oleic acid amide, guanidine oleate, phenyl guanidine stearate, di-(2-ethyl hexyl) guanidine s
- a suitable emulsifier which will enable the finish of the present invention to be readily removed from fibrous materials can be selected by one of ordinary skill in the art from the many that are now commercially available. It is preferred, however, to use non-ionic surface-active compounds such as ethylene oxide adducts of straight chain aliphatic alcohols or acids which have from 12 to 18 carbon atoms. From 2 to 20 or more moles of ethylene oxide may be condensed with the aliphatic acid or alcohol and the resulting condensate may be esterified with a mole of a straight chain aliphatic acid having from 12 to 18 carbon atoms.
- non-ionic surface-active compounds such as ethylene oxide adducts of straight chain aliphatic alcohols or acids which have from 12 to 18 carbon atoms. From 2 to 20 or more moles of ethylene oxide may be condensed with the aliphatic acid or alcohol and the resulting condensate may be esterified with a mole of a straight chain aliphatic acid having
- polyoxyethylene compounds are defined herein as dendro acids or alcohols with a number such as 6 or 12 preceding the dendro notation designating the number of moles of ethylene oxide which has been reacted with each mole acid or alcohol.
- suitable emulsifiers as defined by this terminology are 6 dendro lauric acid, 4 dendro lauric alcohol and 12 dendro oleic acid oleate.

- the finish composition of the presentinvention is applied to fibrous materials formed from hydrophobic cellulosic derivatives such as the lower-aliphatic acid esters of cellulose including cellulose formate, cellulose acetate, cellulose propionate, cellulose butyrate, cellulose acetate-butyrate and cellulose ethers including methyl,
- hydrophobic is utilized in a relative sense to indicate cellulosic derivatives such as those named above, which have a substantially lower afiinity for water than regenerated cellulose.
- the finish may be applied at any time to the formed materials but it is preferred to effect the appli-i Weight are illustrative of the present invention, the scope.
