Definitions

  • the present invention relates to new hexahydropyrimidone derivatives which bear a hydroxymethyl group or an alkoxymethyl group on each of the nitrogen atoms, and to the use of these new substances as agents for finishing textile material consisting of or containing natural or regenerated cellulose.
  • fibrous material consisting of or containing natural or regenerated cellulose may be impregnated from an aqueous liquor with N-hydroxymethyl N-methylol) or N-alkoxymethyl compounds of aliphatic or cyclic ureas, for example urea, thiourea, ethylenurea, propylenurea, glyoxalmonoureine, urones, triazinones or melamine or the urethanes or mixtures of such compounds, dried, optionally subjected to a mechanical shaping treatment and heated to elevated temperatures in the presence of acids or compounds which split off acids. Crease resist, shrinkproof, embossed, schreiner and chintz finishes may be prepared by such a treatment.
  • Dry crease angles and wet crease angles of similar size are obtained, and the size could be adapted to all requirements were it not for the fact that the tensile strength of the treated material decreases as the dry crease angle is increased. According to recent knowledge, the best characteristics are obtained when a high wet crease angle and a medium high crease angle are imparted to the fibrous material with only slight fiber damage.
  • deferred curing or delayed curing Another prior art method of textile finishing is that known as deferred curing or delayed curing. This consists in impregnating the textile material to be finished with an aqueous solution of one or more finishing agents and one or more acid or potentially acid catalysts, carefully drying the material so that the finishing agent or agents do not react to any appreciable extent if at all, and only after a prolonged interval, which may amount to several months, is the material heated to a temperature at which the finishing agent reacts under the influence of the catalyst, several reactions being involved which for simplicity are usually described collectively as condensation, fixing or curing.

It is therefore used particularly for the production of articles of clothing which are known as permanent press finished; for this purpose fiat textile materials, particularly woven or knitted cloth, consisting of natural or regenerated cellulose or containing the same together with other fibrous materials, such as particularly polyethylene terephthalate or other linear polyesters, polyamides or polyacrylonitriles, are impregnated with a liquor containing the finishing agent and catalyst and also if desired agents for improving handle and other additives, and carefully dried; the dry material, containing mainly unreacted finishing agent and catalyst, is cut, sewn up into articles of clothing and brought into the desired shape for example by ironing, pressing or by means of shaping dummies.

  • shaping means is then heated by saturated steam, super- Delayed curing is not confined to flat textile materials.
  • sewing cotton which is also impregnated with uncured finishing agent and catalyst.
  • finishishing agents having particular properties are suitable for delayed curing. Thus they should remain unchanged for long periods, for example up to eighteen months, in the air dry condition at room temperature in the presence of the cure catalyst. Moreover the final finish should not be damaged if the catalysts remain in the articles of clothing.
  • finishing methods have in common that the textile material to be finished is impregnated with a solution, preferably an aqueous solution, of the finishing agent and an acid catalyst and reacted with the finishing agent with the formation of acetal bonds between the cellulose molecules of the textile material and the finishing agent.
  • a solution preferably an aqueous solution
  • the textile material may be dried wholly or partly and if desired stored for some time and/or made up into articles of clothing in the impregnated but unreacted condition.
  • the said finishes are required to have good resistance to washing, high fastness to chlorine and good abrasion resistance. Good resistance to hydrolysis in acid medium is also required in many cases.
  • the finishing agent should not impair the light fastness of dyed material, for example with direct dyes or reactive dyes.
  • N,N'-dimethylolpropylenurea give excellent resistance to chlorine but the resistance to acid hydrolysis of these finishes is inadequate for many purposes and moreover they have a very unfavorable influence on the light fastness of dyeinga.
  • N,N' dimethylol-4,5-dihydroxyimidazolidone-2 on the other hand has no negative influence on the light fastnoss of dyeings, but it yields finishes which have inadequate resistance to chlorine.

  • the impregnated fibrous material may be dried and then heated in the presence of acid or potcntially acid catalysts to temperatures of up to 180 C., preferably to 160 C. Under these conditions, the reaction is usually over in one to six minutes.
  • the fibrous material may be mechanically shaped, for example by compression, crimping, ironing, calendering, embossing or pleating, during or after drying.

  • the finishing agent is applied to the textile ma terial by conventional methods, for example by impregnation of the material being treated with an aqueous liquor by means of a padding machine.
  • the textile material is then dried so that the finishing agent does not cure prematurely; adequate protection against this is not to allow the drying temperature to rise above 100 C.
  • the material is usually dried to a water content of 2 to 15% by weight.
  • the textile material may be kept for many months and then made up for example into articles of clothing.

  • examples are inorganic and organic acids. such as sulfuric acid, hydrochloric acid, phosphoric acid, boric acid, formic acid, acetic acid, oxalic acid, tartaric acid, rnaleic acid and salts which have an acid reaction or form acids by the action of heat and/or by hydrolysis,
  • the reaction of the finishing agents to be used according to the invention is carried out in the presence of these catalysts. This may be effected by applying the catalysts, preferably in the form of aqueous solutions, to the material to be finished, before or after impregnation of the same. It is preferred however to add the catalysts direct to the impregnating bath con taining the finishing agent.
  • concentration of the catalysts is chosen in the conventional range for the particular finishing process being used.
  • catalyst concentrations of from 1 to 40 g./l. and amounts of catalysts (on the weight of finishing agent) of 4 to 60%, preferably 20 to 40%, whereas for finishing the fibers in the swollen condition, i.e. in the presence of considerable amounts of water. and at lower temperatures it may be necessary, as is well known, to use strongly acid catalysts in a concentration of up to 20 N.
  • Another advantage of the new finishing agents becomes evident in the joint use with catalysts in a bath. They have very much better hydrolysis resistance than the N,N'-dihydroxymethyl and N,N-dialkoxymethyl compounds hitherto used. The result of this is that finishing liquors which contain the new finishing agents with catalysts are substantially more insensitive to high catalyst contents and considerably more stable in storage than those which contain prior art finishing agents.
  • Nitrogenous and nitrogen-free hydroxymethyl or alkoxymethyl compounds for example those of urea.
  • melamine and other aminotriazines monocarbamic esters, dicarbamic esters and also polyethylene glycol formals and compounds containing epoxy groups, as for example glycol diglycidol ethers, such as have been used hitherto, may be used with the new finishing agents.

  • sizing agents are cellulose ethers, cellulose esters and alginates.
  • finishing agents to be used according to this invention give finishes having very high resistance to hydrolysis. Textile material finished in this way is therefore unusually resistant to hygienic treatment. Moreover the new agents prevent damage to the textile material by large amounts of catalyst and do not impair the light fastness of dyed material. The preferred agents moreover give finishes having excellent fastness to chlorine.
  • Textile material which has been finished according to this invention with substances having the Formula VI contains cellulose molecules (indicated by Cell in the formula) which are combined together according to the formula:
  • the textile material for treatment according to this invention may be any textile material, such as fibers, filaments, threads, yarns, knitted cloth, woven cloth, netting, nonwoven fabric and felt of natural or regenerated cellulose, such as cotton, rayon staple, rayon and linen and mixtures with each other or with other fibers, for example, of wool, silk, cellulose esters, linear polyamides, linear polyesters and acrylonitrile polymers.
