Definitions

• fibrous material containing or consisting of keratin can be durably shaped in the required manner by impregnating it with a mercaptocarboxylic acid and then oxidizing it, or treating it with steam, while shaping.
• This method has a number of disadvantages which complicate or limit its use. For example, it is difficult to produce consistent results; colored articles readily undergo color changes at the treated places, and intensely red discoloration occurs when iron ions are present; moreover, the treatment has to be carried out by garment manufactures rather than by weavers.
• Salts of monoethanolamine have also been proposed for durable shaping of keratinous fibrous material.
• the effects obtainable are not sufficiently durable to laundering.
• the method of the invention comprises impregnating fibrous material with an aqueous solution or dispersion of a compound-which in the betaine form has the general formula where R is an unsubstituted or substituted hydrocarbon radical, R and R are hydrogen atoms or lower alkyl radicals preferably having from one to five carbon atoms, and R and R are hydrogen atoms or unsubstituted or substituted hydrocarbon radicals preferably having from one to 20. carbon atoms, and heating the impregnated materials with steam at 100 to 150 C while shaping, if desired after drying, intermediate storage and/or making it into garments.
• the radicals R, R and R in Formula I may be for example alkyl, cycloalkyl, aryl or aralkyl radicals having from one to 20 carbon atoms which may bear substituents such as hydroxyl or alkoxyl groups.
• suitable radicals are methyl, ethyl, Z-hydroxyethyl, propyl, 2-hydroxypropyl, butyl, 2-ethylhexyl, octyl, dodecanyl, cyclohexyl, phenyl, tolyl, benzyl, methoxyethyl, ethoxyphenyl and 4-ethoxybutyl.
• radical R contains up to carbon atoms
• R and R are hydrogen or methyl and R and R are hydrogen or aliphatic radicals having up to two carbon atoms.
• the substances to be used for the purposes of the invention are shown in Formula I in the betaine form.
• the radicals R and/or R are not hydrocarbon radicals, the substances may also be present in the form of ordinary salts in which the nitrogen atom has lost its positive charge owing the elimination of a proton, and the negative charge of the resultant anion is compensated by a separate cation X
• the nature of the cation X has no appreciable effect on the suitability of the substances to be used according to the invention.
• an alkali metal, ammonium or substituted ammonium ion in particular one having the formula R-NH -R Whether the substances to be used according to the invention are present in the impregnating liquor in the betaine form or in the form of a salt 11 or II] depends on the pH of the liquor, also in generally the case with dipolar ions.
• the compounds of the general Formula I, II or II are used in the form of their aqueous solutions or dispersions, especially their aqueous solutions. They are applied to the fibrous material in the usual manner, for example by knife coating, sprying, dipping or preferably by padding. It has been found advantageous to apply the solutions or dispersions at such a rate that 0.01 to 0.2 mole, preferably 0.02 to 0.1 mole, of a compound of the general Formula I, II or III is applied per kilogram of material to be treated.
• wetting agents it is sometimes expedient to add wetting agents to the impregnating liquors in order to achieve rapid penetration and equal distribution of the ingredients.
• Non-ionic wetting agents are preferred.
• Wetting agents are dispensible if the material has already been wetted in an earlier treatment.
• the impregnating liquors may contain other ingredients conventionally used for treating keratinous fibers, for example water and oil repellents, such as silicones and compounds having perfluorinated carbon chains.
• the fibrous material can be immediately brought into the desired shape in the presence of steam, if desired after intermediate drying.
• the special advantages of the new process are however particularly apparent when shaping is carried out later, because after the said intermediate drying operation the impregnated material can be stored for very long periods without the sensitizing effect imparted by the impregnation being lost. Shaping can be carried out at any processing stage in the presence of steam, and the material will retain the shape imparted to it.
• the fibrous material can for example be calendered, embossed, goifered, and particularly pleated and creased.
• the effects obtained are highly durable, i.e., they are not lost in use or any cleaning operations.
• Fabrics containing or consisting of keratin fibers, or garments made of such material can therefore be given an easycare finish.
• the process of the invention furthermore results in a substantial improvement in the handle, and the presence in the fibrous material of unreacted compounds of the general Formula I, II or 111 makes the material easier to shape in garment fabrication.
• the new process can be applied with special advantage after a shrink-resist finishing operation, for example a treatment with oxidizing agents such as dichlorocyanuric acid or salts thereof.
• EXAMPLE 1 Made-up mens trousers of pure wool are sprayed with a percent aqueous solution of the compound of Formula VI at the places where they are to be creased, until the sprayed portions have increased 40 50 percent in weight. The trousers are then arranged in the press and treated for to seconds with steam at 100 to 120 C while pressing to give the desired creases. After the steam has been shut off, the trousers are left in the press for another 20 to seconds, suction being applied for 5 seconds to accelerate cooling.
• the trousers obtained exhibit extremely durable creases.
• EXAMPLE 2 Pure wool cloth (plain weave; 250 g/m is padded with a 5 aqueous solution of the substance of Formula VII and squeezed to a wet pickup of 50 percent. The material is then decatized by treating it for 5 minutes with saturated steam at 2 atm. gauge. Suction is applied for 3 to 5 seconds and the cloth dried on a stenter with 3 percent overfeed at 100 C. The cloth thus treated is distinguished by an improved hand, is smoother in appearance, and has improved crease behavior in the wet condition and a durable decatizing effect.
• EXAMPLE 3 Cloth of the type described in Example 2 is impregnated and dried as described in that example. It is then stored for 3 months and made into trousers. It is found that the trousers are easier to shape than trousers of the same material which has not been impregnated with the substance of Formula VII. The trousers are steamed in an ironing press in the way described in Example 1. They have sharp and very durable creases and improved crease behavior in the wet condition.
• EXAMPLE 4 Made-up men's trousers of pure wool are sprayed with a 5 percent aqueous solution of the compound of Formula [V at the places where they are to be creased, until the sprayed portions have increased 40 50 percent in Weight. The trousers are then arranged in the press and treated for 10 to 20 seconds with steam at to C while pressing to give the desired creases. After the steam has been shut off, the trousers are left in the press for another 20 to 30 seconds, suction being applied for 5 seconds to accelerate cooling.
• the trousers obtained exhibit extremely durable creases.
• EXAMPLE 5 Pure wool cloth (plain weave; 250 g/m) is padded with a 5 percent aqueous solution of the substance of formula V and squeezed to a wet pickup of 50 percent. The material is then decatized by treating it for 5 minutes with saturated steam at 2 atm. gauge. Suction is applied for 3 to 5 seconds and the cloth dried on a stenter with 3 percent overfeed at 100 C. The cloth thus treated is distinguished by an improved hand, is smoother in appearance, and has improved crease behavior in the wet condition and a durable decatizing effect.
• EXAMPLE 6 Cloth of the type described in Example 5 is impregnated and dried as described in that example. It is then stored for 3 months and made into trousers.

The trousers are steamed in an ironing press in the way described in Example I. have sharp and very durable creases and improved crease behavior in the wet condition.
• EXAMPLE 7 Made-up men's trousers of pure wool are sprayed with a 5 percent aqueous solution of the compound of Formula Vlll at the places where they are to be creased, until the sprayed portions have increased 40 50 percent in weight. The trousers are then arranged in the press and treated for 10 to 20 seconds with steam at 100 to 120 C while pressing to give the desired creases. After the stem has been shut off, the trousers are left in the press for another 20 to 30 seconds, suction being applied for 5 seconds to accelerate cooling.
