Definitions

  • This invention relates to an improved process for the treatment of cellulosic textile materials to impart shrink and crease resistant features.
  • this invention relates to the treatment of cellulosic and cellulosic-containing textile fabrics with diepoxydioxanes.
  • a further disadvantage noted in the use of the polyepoxides to impart wash-and-wear properties is their inability to be sufficiently resistant to acid hydrolysis to tolerate the presence of the strong acid catalysts which are used conventionally for curing formaldehyde on cellulose.
  • Previous attempts to employ polyepoxides in combination with formaldehyde have largely been disappointing due to the acid hydrolysis of the polyepoxide.
  • Another object is to provide a process for treating textile materials with a polyepoxide which does not require the use of emulsifying agents or non-aqueous solvents.
  • a further object of the present invention is to provide textile treating solutions containing a novel polyepoxide which when applied to a textile fabric can be cured quickly and at low temperatures.
  • Another object is to provide a process for treating textile materials with a polyepoxide which is re sistant to acid hydrolysis and can be employed in combi- 3,135,579 Patented June 2, 1964 nation with formaldehyde.
  • a further object of this invention is to provide a process for treating textile materials with diepoxydioxanes.
  • a still further object is to provide a process for treating textile materials with 2,3-bis(2,3- epoxy-propoxy)-1,4-dioxane.
  • this invention is directed to a process for treating cellulosic and cellulosic-containing textile materials whereby the material is rendered both shrink and crease resistant while imparting to the material after laundering a soft, smooth finish without ironing which comprises impregnating the textile material with a diepoxydioxane. Thereafter the material is heated to promote the reaction of the polyepoxide with the fabric and thereby impart the shrink and crease resistant features.
  • a further unique advantage of the polyepoxides used in the process of this invention is their resistance to acid hydrolysis. This feature renders the polyepoxide especially attractive for use in blends with formaldehyde which is cured conventionally by strong acid catalysts.
  • formaldehyde itself is a highly efficient and inexpensive cross-linking agent a more efficient and economical treatment can be employed to impart the desired wash-and-wear properties to textile fabrics.
  • fabrics treated with the aforementioned polyepoxides and formaldehyde possess properties superior to those obtained using the same amount of either of the components separately. For instance, a significantly lower loss of fabric strength was found than when formaldehyde was employed as the sole reactant.
  • diepoxydioxanes which are suitable for use in the practice of the instant invention are the bis(epoxyalkoxy)- dioxanes represented by the following formula:
  • R represents a divalent hydrocarbon radical of from 1 m3 carbon atoms
  • R represents a monovalent radical selected from the group consisting of hydrogen and methyl.
  • Illustrative compounds which can be employed include, 2,3-bis(2,3-epoxypropoxy)-1,4-dioxane, 2,5-bis(2,3-epoxypropoxy)-l,4-dioxane,
  • the diepoxydioxanes are prepared by the reaction of the corresponding diolefinic diether dioxane precursor, i.e. the bis(alkenyloxy)dioxane, with an organic peracid.
  • the peracids contemplated include, for example, the aliphatic pcracids, the cycloaliphatic peracids, the aromatic peracids, and the like.
  • the organic hydrocarbon peracids are preferred.
  • Illustrative peracids include, for instance, peracetic acid, perpropionic acid, perbutyric acid, perhexanoic acid, perdodecanoic acid, perbenzoic acid, monoperphthalic acid, and the like.
  • the lower aliphatic hydrocarbon peracids which contain from 2 to 4 carbon atoms are highly suitable. Peracetic acid is most preferred. It is highly desirable to employ the peracid as a solution in an inert normally liquid organic vehicle such as ethyl acetate, butyl acetate, acetone and the like. A solution comprising from about 10 to about 50 weight percent of peracid, based on the total weight of peracid and inert organic vehicle is suitable; from about 20 to 40 weight percent is preferred.
  • the epoxidation reaction can be conducted at a temperature in the range of from about C., and lower, to about 100 C., and higher, and preferably from. about 25 to about 75 C.
  • the unreacted diolefinic diether precursor, acid' by-product, unspent peracid, inert vehicle, if employed, and the like can be recovered from the reaction product mixture, for example, by distillation under reduced pressure. Further well-known purification techniques can be employed, as desired.
  • the diolefinic diether precursor can be prepared by the reaction of 2,3-dichlorodioxane or 2,5-dichlorodioxane with the appropriate monoethylenically unsaturated alcohol or mixtures thereof, preferably in a molar ratio of one mole of dichlorodioxane to at least two mols of monoethylenically unsaturated alcohol.
  • This reaction readily proceeds at room temperature, e.g., about 24 C., and the gaseous hydrogen chloride by-product can be continuously removed during the reaction.
  • the desired diolefinic diether precursor can be recovered from the resulting reaction product mixture via conventional techniques such as distillation, fractionation, crystallization, and the like.
  • the 2,3-dichlorodioxane reagent can be prepared by reaction of dioxane and chlorine gas, at elevated temperatures, e.g., about 70 to 100 C., in the absence or presence of a catalyst, e.g., stannous chloride. Thereafter, nitrogen gas can be bubbled through the resulting reaction product mixture to remove any unreacted chlorine, if desired. Unreacted dioxane can be removed from said reaction product mixture by conventional means, e.g., distillation under reduced pressure, thus giving 2,3-dichlorodioxane.
  • a catalyst e.g., stannous chloride
  • the 2,5-dichlorodioxane reagent can be prepared by the il reaction of dioxane and chlorine gas, at relatively low temperatures, e.g., about 30 C. to about 0 C., generally in the presence of an inert normally liquid organic vehicle, e.g., carbon tetrachloride.
  • the resulting reaction product mixture then can be cooled in a Dry Ice bath which causes 2,5-dichlorodioxane to crystallize from said reaction product mixture.
  • the 2,5-dichlorodioxane is readily recovered therefrom via well-known techniques, e.g., crystallization.
  • the objectives of the present invention can best be achieved by impregnating the fabric with an aqueous medium containing the bis(epoxyalkoxy)dioxane and a curing catalyst. Impregnation is effected by a conventional padding operation.

  • the bis(epoxyalkoxy) dioxanes, particularly 2,3-bis(2,3- epoxypropoxy)1,4-dioxane have a distinct advantage of being miscible in most all proportions with water at 25 C.
  • emulsifying agents or organic solvents may be needed, however, in those instances when water insoluble components are added to the textile treating solution.
  • emulsifying agents and solvents which can be employed if required are methylcellulose, hydroxyethylcellulose, carboxymethylcellulose, sodium alginate, polyvinyl alcohol, polyethylene oxide, toluene, Xylene, the lower aliphatic alcohols such as ethyl alcohol, butyl alcohol, isopropyl alcohol, acetone, esters, and the like.

While drying may be accomplished by allowing the fabric to remain in contact with the air, a temperature range of from about 95 F. to about 175 F. for 5 to 1 minutes is preferred. Since the drying time is not critical, a wider range of drying temperature can be employed equally as well.

Temperatures from about 240 to about 400 F. and more preferably from about 275 F. to about 350 F. can be employed for periods ranging from about secondsto about 5 minutes, with the higher temperatures using the shorter curing period.
  • the fabric is scoured to remove unreacted polyepoxide or epoxy curing catalyst. Scouring is effected by washing in hot water (approximately 170 F.) containing a small quantity of detergent.
