Definitions
- This invention is directed at improving the bleaching of textiles with aqueous alkaline hydrogen peroxide.
- Bleaching of fabrics and fibers with hydrogen peroxide is well-established practice.
- the scoured and desized textile is caused to absorb an aqueous alkaline bleaching solution containing hydrogen peroxide, caustic soda, often with sodium silicate and a wetting agent, and with chelating agents to prevent metal precipitation.
- the saturated fabric is then treated at elevated temperatures approaching the boiling point, which may be elevated well above 212 F. by the use of pressure. Effective bleaching is obtained, with excellent results.
- This invention is applicable to the bleaching of cellulosecontaining textiles such as cotton, linen, rayon and the like, and blends of these fibers with synthetics.
- the textiles are spun into yarns, after which sizing agents such as starch or other polymers which aid in processing are applied; the yarns may be bleached or made into fabrics.
- sizing agents such as starch or other polymers which aid in processing are applied; the yarns may be bleached or made into fabrics.
- the so-called greige goods are then desized and scoured, and bleached. Maximum brightness in the bleached fabric without injury to the fabric by cellulose degradation is wanted, and rapid and uniform absorbency is also desired, for subsequent finishing and dyeing operations.
- the desized and scoured fabric is caused to absorb an aqueous alkaline hydrogen peroxide solution, which generally contains about 0.5 to 1.5 percent of hydrogen peroxide, based on weight of material (percent OWM), and sufficient alkali to get the pH up to the range of about 9 to 14, generally by a combination of caustic soda and sodium silicate.
- Wetting agents are conventionally used to insure fast wet-out of the textile; they may be anionic, cationic or nonionic. Most mills use chelating agents to prevent interference by trace metals during processing.
- the textiles are preferably padded with a hot solution, at temperatures of 140 to 160 F. The saturated fabric is then heated to the boiling point.
- the chemicals are rinsed out of the textile, and the product further treated as required.
- an increase of about 2 points in reflectance is obtainable with about 0.2 to 0.3 percent of peroxydiphosphate; at the same time, the noncellulosics are reduced to about 60 to percent of the values obtained without the peroxydiphosphate.
- Example 1 Prior Art for Comparison A sample of percent cotton Oxford was bleached with 2.1 percent (50 percent) hydrogen peroxide, 0.15 percent sodium hydroxide, 1.0 percent silicate (sodium) and 0.1 percent Triton X-lOO (wetting agent) at 212 F. for 60 minutes. The reflectance obtained was 86.3 percent. Percentages are on weight of fabric. Fabric was saturated to 100 percent wet pickup at room temperature and steamed.
- Example 2 Prior Art for Comparison A sample of 100 percent cotton Oxford was bleached as in Example 1, but with 1.05 percent (50 percent) hydrogen peroxide, and the reflectance obtained was 85.9 percent.
- Example 3 Prior Art for Comparison A sample of 65/35 polyester/cotton fabric was bleached with 2.1 percent (50 percent) hydrogen peroxide, 1.75 percent silicate (sodium), 0.30 percent sodium hydroxide and 0.1 percent Triton X-100 (wetting agent) at 212 F. for 60 minutes. The total reflectance obtained was 95.2 percent.
- This Invention A similar sample of polyester/cotton fabric was bleached as above, but 0.2 percent tetrapotassium peroxydiphosphate was added to the bleach solution. The reflectance increased from 95.2 to 97.3 percent.
- Example 4 Prior Art for Comparison In a mill trial, a 100 percent cotton terry toweling was bleached with 1.3 percent sodium hydroxide, 1.34 percent sodium silicate, 2.3 percent (35 percent) hydrogen peroxide, 0.03 percent wetting agent, and 0.039 percent chelating agent. A reflectance of 86.4 percent was obtained.
- the terry ills a period of time for the peroxide to react, the improvement which comprises having present in the aqueous solution from 0.05 to 0.5 percent on weight of textile material, of a water- :soluble peroxydiphosphate.
