Definitions

  • 1l rIhis invention relates-to a method oftreating fabrics ⁇ or othervtextile materials consisting Wholly or partlyvof Wool, to reduce the -natural tendency to shrink-Whenwashed invaqueous liquors.
  • Wool goods are usually treated to render ⁇ them unshrinkablewith an acidiiied solution of ahypochloriteat a pH varying from 1 to5 according to the nature of theuacid, and the quantity employed. Under these conditionsthe ⁇ yvool fibre has such a sbtrongraffinityfor the halogen,-that complete exhaustion of ⁇ the A bath takes place ⁇ Within a fewl minutes.- This procedure cannot he expected'togive uniform penetration of ⁇ *the chlorinating agent, especially?v Where highly twisted yarns or thick fabrics are yunder treatment, and it generally results inlthe surface bres being over treated, while those in the Vcentre of the yarn criabricremaineappreciably unaiected.
  • nitrogen chloro compounds used in e,this.speciiic'a'tion' is intended to cover only nitro "chloro compoundsin 'Which'the' chlorine 'atom is directlyattached .to the" nitrogen atom and'wiierein tlief chlorine is available chlorine;
  • the oxidising agent has the effect of making the animal fibres more susceptible to attack by the halogen-containing agent, with which they react to give materials having a high degree of unshrinkability.
  • Our invention further comprises treating the materials with a dilute aqueous solution of a.
  • permanganate compound mixed with a dilute aqueous solution of an alkali metal or alkaline earth metal hypochlorite or hypobromite at a regulated pH Value.
  • Our invention further comprises a ⁇ process in which the materials are first treated in a dilute aqueous solution of a permanganate compound (e. g., an alkali metal permanganate) at a pH of approximately to approximately 10, and at a temperature not exceeding 60 C., and subsequently treated in a dilute aqueous solution or suspension of a nitrogen-chloro compound of the type such as nitrogen trichloride, monochloramine, p-toluene-sulphonchloramide, etc., at a pH of approximately 1 to approximately 3.
  • a permanganate compound e. g., an alkali metal permanganate
  • a nitrogen-chloro compound of the type such as nitrogen trichloride, monochloramine, p-toluene-sulphonchloramide, etc.
  • Our invention further comprises a process in which the materials are treated in a dilute aquecus solution of a permanganate compound (e. g., an'alkali metal permanganate) at a pH of approximately 5 to approximately 10V and at a temperature not exceeding '60 C. and subsequently treated in an alkaline solution of ⁇ an alkali metal or alkaline earth metal hypochlorite or hypobromite, with or without the addition of metallic salts such as magnesium sulphate, calcium chloride, calcium acetate, barium chloride, barium acetate and/ or zinc sulphate at a pH of approximately 7.5 to approximately 11.
  • a permanganate compound e. g., an'alkali metal permanganate
  • Our invention further comprises treating the materials with a liquor which is alkaline and contains a dilute aqueous solution of an alkali metal or alkaline earth metal hypochlorite or hypobromite, together with a permanganate compound (e. g., an alkali metal permanganate) at a pH, of approximately '7.5 to approximately 11.
  • a permanganate compound e. g., an alkali metal permanganate
  • the oxidising agent has theeffect of making the animal fibres more susceptible to attack by the halogen-containing, agent, with vwhich they react to give materials having ahigh degree of unshrinkability.
  • a relatively small concentration of permanganate e. g., 1 to 2% on the weight of the textile material, is required, and whilst for economic reasons one would employ the lowest concentration which gives the desired; results, we have found that higher concentrations such as 5 or 6% have no deleterious effects.
  • the treatment with permanganate may be carried 'out in the cold or at varied temperatures, e. g., to 60 C.
  • the treatment with the halogencontaining agent may be carried on until exhaustion of the halogen is obtained, and it is preferably followed by an antichlor treatment.
  • the solutions used are preferably adjusted to pH values ranging from5 to 6 for the oxidising pretreatment, from 1,to 2 for the nitrogen-chloro solution, and from 8to 10 for the hypohalite solution.
  • Resistance to shrinkage is alsov induced by rst subjecting the animal libres to treatment with a dilute aqueous solution of alkaline hypohalite particularly in the presence of the above metallic salts, and after exhaustion ofthe bath to give the additional oxidation with'permanganate, maintaining alkaline conditions throughout.
  • alkali hypohalite as used herein is intended to designate alkali metal and alkaline earth metal hypochlorites and hypobromites.
  • the animal fibres. are subjected to ⁇ an even anti-shrink-treatment,which is readily controlled, and shows low; loss of proteinmatter.
  • the treatedA wool develops an improved soft handle and lustre, and retains its loftiness and resiliency even onv repeated washing.
  • a bleaching treatment may be. given Vsimultaneously with theV anti-'shrinkprocess.
  • the process can be carried-out in almost any type of machine, i., e .,wood.stainless steel, etc.
  • Acidied bisulphite solution is then added and processing continued until the discolouration of the permanganate is removed.
  • Example 5 --100 parts of 12/4 Botany yarn in the grease are treated with 2500 parts of Water containing:
  • aqueous liquors comprising treating such materials with a dilute aqueous solution of an alkali metal permanganate at a pI-I o f not less than about 5 and with a dilute aqueous solution containing a substance selected from the group consisting of alkalihypohalite at a pH of at least 7f.5 and a nitrogen-chloro compound in which the chlorine atom is directly attached to the nitrogen 4atom and in whichthe chlorine is present as available chlorinehaving a pI-I of about 1 to 3.
  • a method of treating fabrics and other textile materials consisting at least in part of wool, to reduce the natural tendency to shrink when washed in aqueous liquors comprising treating the textile materials with a dilute aqueous solution of an alkali metal permanganate mixed with a dilute aqueous solution containing an alkali hypohalite at a pH of approximately 7.5 to approximately 11.
  • a method of treating fabrics and other textile materials consisting at least in part of wool, to reduce the natural tendency to shrink when washed in aqueous liquors comprising treating the textile materials with a dilute aqueous solution of an alkali metal permanganate at a pI-I of 5 to 10 and at a temperature not exceeding 60 C'., and subsequently treating them with a dilute aqueous solution containing a nitrogen-chloro compound at a pH of 1 to 3.

  • a method of treating fabrics and other textile materials consisting at least in part of wool, to reduce the natural tendency to shrink when washed in aqueous liquors comprising treating the textile materials with a dilute aqueous solution containing an alkali hypohaliteat a pH of 7.5 to approximately 11 and subsequently treating them with a dilute aqueous solution of an alkali metal permanganate at a pH over 7.
  • a liquor for treating textile materials containing Wool in order to reduce the natural tendency to shrink when Washed in aqueous liquors, said liquor containing an alkali metal permanganate, an alkali hypohalite and a metal salt selected from the group consisting of magnesium sulphate, calcium chloride, calcium acetate, barium chloride, barium acetate, zinc sulphate having a pH of approximately 7.5 to approximately 11. y
