Definitions

  • the bath used for impregnation contains a polyvinyl ester of an aliphatic carboxylic acid.
  • polyvinyl esters of carboxylic acids of low molecular weight that is to say, those containing 2-4 carbon atoms, for example, polyvinyl butyrate, polyvinyl propionate and especially polyvinyl acetate.
  • polyvinyl esters or copolymers of vinyl esters containing different acid radicals and also partially hydrolyzed polyvinyl esters.
  • The'polyvinyl ester must be emulsified in the impregnating bath by means of an anion-active dispersing agent.
  • anion-active dispersing agents there may be mentioned more especially those which owe their surfaceactive properties, on the one hand, to a hydrophobic 2,982,673 Patented May 2, 1961 radical, especially an aliphatic radical, and, on the other, to an group.
  • This. group may be bound to a carbon atom either directly, in which case it is a sulphonic acid group, or advantageously through an oxygen atom, in which case it is a sulphuric acid ester group of the formula
  • Especially advantageous dispersing agents of the latter kind are sulphated oils, especially Turkey redoil.
  • the impregnating bath contains at least one non-ionic dispersing agent, in addition to the anion-active dispersing agent.
  • non-ionic dispersing agent for this purpose there are preferably used polyglycol compounds, that is to say, compounds in which a polyglycol radical of the formula (--CH -CH O) --CH -CH -OH is bound to an amine, alcohol or mercaptan, or is bound. to the radical of an acid containing at least 8 carbon atoms.
  • polyglycol compounds that is to say, compounds in which a polyglycol radical of the formula (--CH -CH O) --CH -CH -OH is bound to an amine, alcohol or mercaptan, or is bound. to the radical of an acid containing at least 8 carbon atoms.
  • mixtures of such compounds and, if desired, other substances that enhance the dispersing action are, for example, mixtures of (a) Polyglycol esters of saturated or especially unsaturated aliphatic carb
  • the impregnating baths also contain a metal salt capable of reversing the charge of anion-active products.
  • a metal salt capable of reversing the charge of anion-active products.
  • aluminum salts such as aluminum formate or especially aluminum sulphate.
  • the impregnating bath must have an acid reaction, and this is advantageously achieved by the addition of a small proportion of acetic acid.
  • the impregnating baths may contain other substances, for example, a small proportion of a reducing agent, which is added in order to inhibit subsequent yellowing of the textile material or of the polyvinyl ester.
  • a reducing agent which is added in order to inhibit subsequent yellowing of the textile material or of the polyvinyl ester.
  • the process of this invention for reducing the translucency of the fabrics may be combined with other treatments, such as dyeing, softening, matting or an antistatic treatment.
  • the individual and relative proportions of the components of the impregnating bath may vary within relatively wide limits.
  • concentration of the polyvinyl ester depends primarily on the strength of the effect desired, and may be, for example, 1-10% calculated on the weight of the fibrous material.
  • concentration of the dispersing agent is advantageously adjusted in relation to the quantity of polyvinyl ester to be emulsified, in that the dispersing agent is present in at least the proportion required to form a sufliciently stable emulsion. In general the proportion of the dispersing agent required is only a small fraction of the quantity of polyvinyl ester present.
  • the proportion of the metal salt capable of reversing the charge of anion-active products is advantageously a multiple of the quantity of the anion-active dispersing agent and is less than or at most equal to the quantity of the polyvinyl ester, for example, about ,5 to $6 the quantity of the polyvinyl ester.
  • the impregnating bath may be prepared by emulsifying the polyvinyl ester in water, with the aid of the dispersing agent or agents in the usual manner. It is preferable however, to dilute with water to thedesired bath strength a concentrated aqueous emulsion of the polyvinyl ester containing at least one dispersing agent, ad vantageously the anion-active dispersing agent which is essentially in the process, and to add to the diluted emulsion the further substances necessary for carrying out the process, that is to say, the metal salt, the acid and, when used, the other products mentioned above, such as the non-ionic dispersing agent.
  • the impregnation is advantageously carried out at a temperature from room temperature up to a moderately raised temperature, for example, a temperature within the range of 20 C. to 50 C.
  • a moderately raised temperature for example, a temperature within the range of 20 C. to 50 C.
  • An especially suitable apparatus for this purpose is a igger.
  • the impregnated textile material is then dried, advantageously after being rinsed with cold water.
  • the drying may be carried out at room temperature or a raised temperature, for example, at temperatures up to 100 C. 1
  • the Woven or knitted fabric so pretreated is then sub jected to a calendering treatment at a raised temperature, advantageously at a temperature within the range of 150 C. to 200 C.
  • the pressure of the calendering rollers against the fabric is advantageously somewhat high, for example, about 30-70 kilograms per centimetre of the roller length.
  • smooth calendering rollers or advantageously rollers having fine parallel con rugations may be used. The effects produced by the process of this invention are distinguished by their level character and good resistance to washing.
  • the fabric so treated is no longer translucent, and the .effect so produced has a good resistance to washing.
  • a process for reducing thetranslucency of fabrics of polyamide fibres which comprises impregnating the fabric in an aqueous acid bath which contains polyvinyl acetate emulsified with an anion-active dispersing agent containing a sulphuric acid ester group and also contains an aluminum salt capable of reversing the charge of anion-active products, drying the impregnated fabric acid then. subjecting it to a calendering treatment at a raised temperature.
  • a process for reducing the translucency of fabrics of polyamide fibres which comprises impregnating the fabric in an aqueous acid bath which contains polyvinyl acetate emulsified with an anion-active dispersing agent containing a sulphuric acid ester group and also contains an aluminum salt capable of reversing the charge of anion-active products, and a polyglycol compound, drying the impregnated fabric and then subjecting it to a calendering treatment at a raised temperature.
  • a process for reducing the translucency of fabrics of polyamide fibres which comprises impregnating the fabric in an aqueous bat-h acid with acetic acid which contains polyvinyl acetate emulsifiied with Turkey red oil and also contains aluminum sulphate and a mixture of'a polyglycol ester of an aliphatic carboxylic acid of high molecular weight, of a polyglycol ether of an aliphatic mercaptan of high molecular weight, and of a free aliphatic carboxylic acid of high molecular weight,
  • a process for reducing the translucency of fabrics of polyamide fibres which comprises impregnating the fabric in an aqueous bath acid with acetic acid which contains polyvinyl acetate emulsified with Turkey red oil and also contains aluminum sulfate and a mixture of oleic acid polyglycol ester, of polyethylene glycol-tertiary dodecyl meroaptan and of oleic acid, drying the impregnated fabric and then subjecting it at a temperature within the range of 150 to 200 C. to a treatment with a corrugated calender under a pressure within the range of 30 to kilograms per centimeter of the length of the roller.
