Definitions

• the present invention relates to a process for improving textile fabrics and to the auxiliaries in this process; specific details may be seen from the specification following hereafter.
• Cation-active substances such as amines, ammonium compounds, guanides and biguanides of high molecular weight are often used in textile processing especially for softening artificial silk. It may be regarded as a disadvantage that these compounds, generally used in the form of their salts, form diflicultly soluble sulphates and often unfavorably influence the shade and the fastness to light of the dyeings,
• This invention is based on the observation that the metal complex salts of guanides and biguanides having an alkyl radical of at least carbon atoms, for instance, a cetyl, undecyl, oleyl, lauryl or octodecyl radical, may be used with special advantage for processing textiles. They have the same valuable properties as the amines proper but do not afiect the shade and the fastness to light of the dyed material.
• metal complex salts of copper, cobalt, chromium and nickel may be obtained, for instance, by combination of the bases or of their water-soluble salts with the chlorides of the above mentioned metals.
• the molecular proportion is advantageously chosen so that no constituent is present in excess, that is to say, the solution or suspension of the reaction partners must not contain free ions of metals or of bases.
• a very good auxiliary in textile processing is, for instance, obtained by reaction of 1 mol of copper chloride with 2 mols of octodecylbiguanide hydrochloride, if desired, in conjunction with protective colloids and solvents such as methyl-, ethyl-, propyl-, butylor benzyl alcohol.
• the metal complex salts are suitable as softeners and as dulling-, levellingand through-dyeing assistants for artificial silk, artificial silk staple fibre, cotton or the like as well as preservatives of textiles, for instance, fishing nets, sacks, ropes or the like.
• Example 1 octodecyl biguanide hydrochloride are stirred for a short time at a raised temperature together with 14 parts of methanol, 2 parts of a product obtained according to Example 23 of the U. S. Specification 1,970,578 and 4 parts of copper chloride containing water of crystallization and the whole is allowed to cool. A green paste is obtained which dissolves in water to a bluish pink solution.
• Undyed material is practically not coloured by the above treatment.
• Example 32-50 parts of zinc sulphide are stirred into a paste with ,5 parts of a preparation obtained according to Example 1, 0.5 part of a product made according to the U. S. Specification 1,970,578 and 10 parts of water.
• a solid, strong mat efiect is obtained which is fast to rinsing and at the same time the material is given an agreeable, full and soft feel.
• Example 4 Fishing nets made from crude cotton are treated for 1 hour at room temperature in an aqueous solution of 02-05% of the preparation described in Example 1, calculated upon the weight of the goods, the proportion of the goods to the liquor being 1:4.
• the preparation is absorbed by the fibre and is not removed therefrom by rinsing.
• the nets thus prepared are fast to rotting.
• the highly preserving action of the above solution is evident from the following: Whereas the untreated net after having been kept for 6 weeks in moist earth is practically entirely decomposed (only some knots will be found) a net treated according to this example preserves under the same circumstances almost its entire resistance to tearing.
• complex compound of a water-soluble copper salt and a biguanlde containing an alkyl radical of at least 10 carbon atoms said complex compound Example 2.
• -Viscose artificial silk piece goods being obtained by reacting said copper salt and said guanide in molecular proportions, with neither constituent present in excess so that the resulting reaction mixture contains no free ions of copper or of said guanide.
• the process for improving uncolored textile fabrics which comprises treating: them with -a complex compound of a water-soluble copper salt and a water-soluble salt of a guanide containing an alkyl radical of at least carbon atoms, said complex compound being obtained by reacting said copper salt and said guanide in molecularproportions, with neither constituent present in excess so that the resulting reaction mixture contains no free ions of copper or of said guanide.
• the process for improving uncolored textile fabrics which comprises treating them with a complex compound of copper chloride and a guanide containing an alkyl radical of at leastlO carbon atoms, said complex compound being obtained by reacting said copper salt and said guanide in molecular proportions, with neither constituent present in excess so that the resulting reaction mixture contains no free ions of copper or of said guanide.
• the DIOL ss for improving uncolored textile fabrics which comprises treating them with a complex compound of copper chloride and a biguanide containing an alkyl radical of at least 10 tains no freeions of copper orof said guanide.
