Definitions
- persulfates for the oxidative desizing of fabrics made of cellulose fibers and their blends with synthetic fibers, since persulfate is a starch such as e.g. Potato starch, rice starch, maize starch and tapioca, which are used to size fabrics, break down excellently in the presence of alkali.
- a disadvantage of desizing with persulfates is that damage to the cellulosic fibers can easily occur, which is expressed in a sharp drop in the average degree of polymerization.
- the invention relates to a new oxidative desizing agent consisting of 5 to 20% by weight sodium or ammonium persulfate, potassium, sodium, ammonium or calcium peroxodiphosphate, 20 to 50% by weight of one or more surfactants from the group C 8 -C 20- sec.alkanesulfonates, C 4 -C 12 alkylphenol oxethylates with 6-12 units of ethylene oxide and C 10 -C 18 fatty alkoxethylates with 3 to 8 units of ethylene oxide and water corresponding to the balance to 100%.
- the groups of surfactants mentioned above can be taken alone or in combination with one another. Mixtures of an alkanesulfonate and one of the two nonionic surfactants in a weight ratio of 1: 6 or 6: 1 are preferred.
- the desizing agent according to the invention is obtained by dissolving the persulfate or peroxodiphosphate in the surfactant or surfactants at about 50 ° C. for 1-2 hours, allowing it to cool and then diluting it with the required amount of water.
- This surfactant heel sulfate or peroxodiphosphate mixture is suitable for the oxidative desizing of fabrics which contain cellulose fibers alone or in a mixture with synthetic fibers.
- the fabric is impregnated with an aqueous solution of this desizing agent with the simultaneous addition of alkali, preferably sodium hydroxide solution.
- alkali preferably sodium hydroxide solution.
- the material impregnated in this way is brought to a moisture content of approximately 100% by squeezing and subsequently treated at 20-160 ° C. for a period of between 30 seconds and 24 hours.
- the length of the treatment time depends on the respective process-specific temperature and type of dwelling unit.
- the content of the desizing agent described above in the aqueous liquor is 0.5 to 3, preferably 0.8 to 2% by weight, assuming a squeezing effect of 100%.
- the amount of alkali to add is chosen as usual so that the pH of the liquor is always above 10. This generally requires 0.1 to 10, preferably 0.3 to 4,% by weight of solid sodium hydroxide.
- the fabric is expediently washed out with hot water at approx. 85'- 95 ° C for 10 - 60 seconds and then rinsed cold.
- alkali and detergent are expediently added to the wash water.
- This desizing process can also be combined with a conventional bleaching process.
- the fabric is impregnated with an aqueous liquor which, in addition to the desizing agent and alkali in the amount and composition specified above, also contains 30 to 60 ml of H 2 O 2 (35%) in one liter of liquor and sodium silicate as stabilizer.
- the impregnated fabric is again squeezed to approx. 100% and stored for 6 to 24 hours at room temperature or briefly steamed at approx. 100%.
- the fabric is then washed out, with alkali and detergent being added to the wash water to improve the size degradation.
- the advantage of the desizing agent according to the invention is that it is liquid and can therefore be metered easily. It is also very stable in storage and remains stable for up to 6 months at 30 ° C.
- the amount of per-compound required for desizing can be reduced to approximately 25% of the amount of per-compound that would be necessary for desizing alone with a per-compound. This reduction results in a substantial reduction in fiber damage.
- the fer compound and the surfactant are not added separately to the impregnation liquor, but first the mixture prepared from the ferrous compound and surfactant and this mixture is then added to the liquor.
- Cotton nettle sized with starch was impregnated with a solution of the following composition:
- the impregnated material is squeezed to 100% residual moisture content and treated with steam on a steamer at 103 - 105 ° C. The goods are then washed free of alkali with hot water.
- the goods treated in this way have a whiteness of 66.7%.
- the degree of desizing measured according to the violet scale TEGEWA, is 8 - 9.
- the average degree of polymerization (DP) of the treated material is 2550.
- Cotton fabric as in Example 1 is impregnated with a solution of the following composition:
- the impregnated material is squeezed to 100% residual moisture content, wound up and rests in a steam atmosphere with 100% relative humidity at 95 ° C for 1 hour. The material is then treated as in Example 1.
- the goods treated in this way have a whiteness of 67.2%.
- the degree of desizing, measured according to the violet scale TEGEWA, is 8 - 9.
- the DP value of the treated material is 2500.
- Cotton nettle as in Example 1, is impregnated with a solution of the following composition:
- the impregnated material is squeezed to a residual moisture content of 100%, wrapped on a pillow and wrapped with plastic wrap to prevent it from drying out.
- the lump is then left for 16-20 hours at room temperature.
- the goods are then washed out in the first wash baths with the addition of alkali.
- the goods treated in this way have a whiteness of 85%.
- the DP value of the treated material is 2450.
- Cotton nettle as in Example 1 is impregnated with a solution of the following composition:
- the impregnated material is squeezed to a residual moisture content of 100% and treated with steam on a steamer at 100 - 102 ° C.
- the goods are then washed out with the addition of alkali in the first wash baths.
- the goods treated in this way have a whiteness of 84%.
- the DP value of the treated material is 2400.
- Cotton nettle sized with starch was impregnated with a solution of the following composition:
- the material impregnated in this way is squeezed to a residual moisture content of 100% and treated with steam on a steamer at 103-105 ° C. The goods must then be washed free of alkali.
- the goods treated in this way have a whiteness of 68.6%.
- the degree of desizing, measured according to the violet scale TEGEWA, is 8.
- the average degree of polymerization (DP) of the treated material is 2400.
- Cotton nettle as in the previous example is impregnated with a solution of the following composition: Rest of water
- the impregnated material is squeezed to a residual moisture content of 100%, wound on a pillow and wrapped with plastic wrap to prevent it from drying out.
- the lump is then left for 16-20 hours at room temperature.
- the goods are then washed out with the addition of alkali in the first wash baths.
- the goods treated in this way have a whiteness of 84%.
- the DP value of the treated material is 2300.
