Description

EXAMPLE 1

[0156] 48 g of water are introduced in a beaker with stirrer (agitator). While stirring, 15 g of the fatty alcohol Lutensol TO-20 (C13, 20EO) are added. The mixture is heated to 80 C. while the surfactant is completely dissolved. Next, 17 g of a secondary alkanesulphonate (Hostapur SAS 60) are added and dissolved. Successively, 10 g of Dowanol (dipropylene glycol monomethyl ether) and 10 g of aqueous poly-DADMAC (active substance 53%) are added. The initially turbid mixture is cooled while stirring. This forms a clear colloid solution.

[0157] A liquor is prepared by diluting 40 g of the resulting product to 1000 mL with water. The textiles to be finished are finished with the product by dipping in the liquor and subsequent squeezing (padding). The pressure on the padder is chosen so that the wet pickup is 100%.

[0158] After 3, 5 and 10 household washes, the antistatic and hydrophilic properties are measured according to DIN EN 1149-1 or the TEGEWA drip test.

[0159] Polyester (polyethylene terephthalate, knitted fabric): Zero value antistatic 1.010.sup.14 ohms, hydrophilicity >180 sec.

EXAMPLE 2: WASHCLOTH

[0162] Preparation of the Composition

[0163] 47.4 g of water are introduced in a beaker with stirrer (agitator). While stirring, 15 g of the fatty alcohol Lutensol TO-20 (C13, 20EO) are added. Next, 5 g of butyldiglycol are added. The mixture is heated to 90 C. while the surfactant is completely dissolved. Next, 13.8 g of an alkoxylated (4EO) phosphoric acid ester (Hordaphos 222) are added and dissolved. Successively, 1.66 g of sodium hydroxide solution (50%) and 9.2 g of aqueous poly-DADMAC (active substance 53%) are added. The initially turbid mixture is cooled while stirring. This forms a clear colloid solution.

[0164] Production of the Washcloth

[0165] The washcloth comprises a substrate of polypropylene spun fibre fabric with an area of 900 cm.sup.2. The substrate has a mass of 17.3 g.

[0166] The substrate is finished by dipping in the resulting composition and then squeezing (padding). The pressure on the padder is chosen so that the wet pickup is 200%. Next, the finished substrate is dried at 120 C. for 2 minutes.

[0167] Application of Washcloth and Results

[0168] The washcloth thus obtained is washed together with a 0.6 kg accessory pack (household washing at 40 C.). The accessory pack consists of 0.3 kg of polyester (polyethylene terephthalate, knitted fabric) and of 0.3 kg of polyamide (polyamide 6,6; knitted fabric)

[0169] After household washing, the accessory pack is dried for 2 days in air and conditioned for 3 days in an air-conditioned room. Next, antistatic and hydrophilic properties are measured. In order to check for homogeneous finishing, the accessory pack is tested in four different places.

EXAMPLE 3: WASHCLOTH

[0174] Preparation of the Composition

[0175] 43.0 g of water are introduced in a beaker with stirrer (agitator). While stirring, 30 g of the fatty alcohol Lutensol TO-20 (C13, 20EO) are added. The mixture is heated to 90 C. while the surfactant is completely dissolved. Next, 17.0 g of a secondary alkanesulphonate sodium salt (Hostapur SAS 60, active substance 60%) are added and dissolved. The mixture is cooled to 60 C. At this temperature, 9.2 g of aqueous poly-DADMAC (active substance 53%) are added. The initially turbid mixture is cooled while stirring. This forms a clear colloid solution.

[0176] Production of the Washcloth

[0177] Analogously to Example 2, the same proportions are used in the scale 1:10.

[0178] The washcloth comprises a polypropylene spun fibre fabric substrate with an area of 90 cm.sup.2. The substrate has a mass of 1.0 g.

[0179] The substrate is finished by dipping in the resulting composition and then squeezing (padding). The pressure on the padder is chosen so that the wet pickup is 240%. Next, the finished substrate is dried at 120 C. for 2 minutes.

[0180] Application of Washcloth and Results

[0181] The washcloth thus obtained is washed together with a 60 g accessory pack (household washing at 40 C.). The accessory pack consists of 30 g polyester (polyethylene terephthalate, knitted fabric) and 30 g polyamide (polyamide 6,6; knitted fabric). The accessory pack simulates the textiles to be finished by the end user.

[0182] After household washing, the accessory pack is dried for 2 days in air and conditioned for 3 days in an air-conditioned room. Next, antistatic and hydrophilic properties are measured. In order to check for homogeneous finishing, the accessory pack is tested in three different places.
