These components are mixed as in Example 4. The dye dissolved in 21 seconds.
Example 7 Example 6 was repeated, substituting equal quantities of the alkalis indicated below for the Na CO with the satisfactory results, as indicated by the number of seconds required for the dyestufi to dissolve when tested as stated above:
Alkali: Seconds K2003 19 NaOH 14 Na SiO l3 Na SiO l5 N34P207 Na B4O7' Although the preferred alkali is Na CO similar but can be obtained by replacing the Na CO with K CO NaOH, Na SiO Na SiO Na P O or Na B O- 10H O, using substantially the same quantities of these other somewhat less satisfactory results, as indicated above,
materials. For satisfactory results in the practice of the present invention, the elimination of the blue speck or blue'streak formation must last for several months, due
to the time which has elapsed while the sour-blue formulation is in storage and the other alkalis indicated have been found to have this property.
The alkalis indicated are prefarably used in amount corresponding to 13% of the Na- SiF content although 2% is the preferred quantity, but larger amounts can be used with some sacrifice of the alkali-neutralizing efliciency of the sour-blue.
The H SiF is usually present in from 0 to 0.15% based on the Na SiF content.

The dyestuif can be varied according to its strength, but for dyestuffs of the character indicated above the preferred quantities are from 0.0S0.3% based on the Na SiF content.
It will be obvious that other components which are customary components of sour-blue formulations may be used and may be added to the above compositions, for example, the optical whitener which may be Calcofluor White B Conc. made by American Cyanamid Company,
New York, N.Y., may be used, and the customary amount is 0.8% based on the Na SiF content. Similarly, light paraffin oil may be used to prevent dust, and the customary amount is 0.3%.
Generally, the amount of laundry sour-blue added to laundered fabrics is suflicient to lower the pH to 5-6. However, more sour-blue may be used for heavily starched materials like shirts: The amount of sour-blue required to attain the desired lowered pH will vary-with efliciency of rinsing operations and alkalinity of 'the water supply. With low alkalinity water and efficient removal of alkaline detergents, by rinsing prior to souring, one ounce of sour-blue formulation to pounds of fabric is generally suflicient. As much as three or more ounces to 100 pounds of fabric may be required in laundries having high alkalinity water supplies.
It is apparent that many widely different embodiments of this invention may be made without departing from the spirit and scope thereof, and, therefore, it is not intended to be limited except as indicated in the ap pended claims.
We claim:
1. A laundry sour-blue comprising commercial sodium fiuosilicate, a blue dyestufi selected from the group consisting of Blue Dye-Colour Index 707 and Blue Dye- Color Index 698 and 0.1 to 3.0% of an alkali selected from the group consisting of sodium carbonate, sodium hydroxide, sodium orthosilicate, sodium metasilicate, sodium pyrophosphate and sodium tetraborate.
