Definitions

  • the present invention relates to novel bleaching compositions. Specifically, this invention is concerned with bleaching compositions which are aqueous alkaline solutions containing a peroxy compound, an alkali metal silicate and a novel combination which functions as a stabilizing agent for the reduction of the decomposition of the peroxy compound and prevention of silicate deposition.
  • bleaching compositions which are aqueous alkaline solutions containing a peroxy compound, an alkali metal silicate and a novel combination which functions as a stabilizing agent for the reduction of the decomposition of the peroxy compound and prevention of silicate deposition.
  • Preparing textile materials for bleaching, dyeing and finishing generally involves a series of well-known steps.
  • the material is first singed to burn off excess fibers, desized to remove any artificial coating put on the material for processing, rinsed, and then it is scoured. After scouring, the material is again rinsed and then, in succession, it is bleached, scoured, rinsed, mercerized, rinsed, dyed or printed, and finished.
  • These steps are more specifically described in Chemistry and Chemical Technology of Cotton, Interscience Publishers, Inc., New York, NY. 1955, edited by Kyle Ward, Jr., and which is incorporated herein by reference.
  • a discussion per se of the bleaching step starts on page 190 of said publication.
  • bleaching is the fifth major step in the above-described textile finishing process.
  • the general purpose of the bleaching step is to oxidize any foreign matter on the textile material in order to provide a substantially absorbent and white material which is readily acceptive to dyeing.
  • the bleaching (oxidative) process is desirable in order to attempt to remove impurities or foreign matter and thus ultimately prepare a whiteness in color product suitable for subsequent dyeing and effecting a uniformity of color thereon.
  • commercial bleaching (including boiling) processes involve contacting the textile material with alkaline aqueous solution (bath) containing a peroxy compound such as hydrogen peroxide and an alkali metal silicate such as sodium silicate.
  • a stabilizing agent to minimize the decomposition of the peroxy compound is well established in the peroxy bleaching art, because, among other things, the oxygen released by decomposition of the peroxy compound in general has no bleaching action as contrasted with the normal autodecomposition of the peroxy compound which does function as a bleaching agent. In fact, the decomposition of the peroxy compound may be harmful. For example, cellulosic materials in strongly alkaline peroxy (bleaching) solutions are attacked by the oxygen from decomposition with the result of loss of strength by the materials.
  • stabilizing agents are of various and diverse nature and the ability of a material to be an effective stabilizing agent is apparently unpredictable. For example, although a few sequestering agents such as 3,795,625 Patented Mar.
  • the stabilizing agents for peroxy solutions vary in their ability with changes in the prevailing conditions such as pH, temperature conditions and the like of the peroxy solutions.
  • the stabilizing agent should preferably be effective in alkaline solutions and under relatively high temperature conditions which are frequently encountered in practice as well as being compatible with other additives usually present in the peroxy bleaching solutions such as optical whiteners, that is, brighteners or fluorescent white dyes, wetting agents and the like.
  • an object of this invention is to provide an improved method for stabilizing aqueous peroxy solutions.
  • Another object of this invention is to provide a stabilizing agent which affects synergism in the reduction of the decomposition of the peroxy compound and also prevents water-insoluble silicate deposition.
  • Another object of this invention is to provide an improved method for bleaching cellulosic materials using aqueous peroxy solutions having dissolved therein novel stabilizing agents.
  • synergistic stabilizing agent which is a combination of:
  • NTA nitrilotriacetic acid
  • HEDP l-hydroxy ethylidene-l, l-diphosphonic acid
  • HHH Hoi -bi oH HHH and Water soluble salts thereof
  • a water soluble magnesium or calcium salt in the aqueous peroxy solution 1.
  • the water-soluble salts are also included within the scope of the present invention.
  • the preferred salts are the sodium salts.
  • Other alkali metal salts such as potassium, lithium and the like, as well as mixtures of the alkali metal salts may be used.
  • any water-soluble salt, such as the ammonium salt, which exhibit the characteristics of the alkali metal salt may be also used to practice the invention.
  • the magnesium and calcium salts include, without limitation, magnesium acetate, magnesium benzoate, magnesium bromate, magnesium bromide, magnesium chlorate, magnesium chloride, magnesium chromate, magnesium citrate, magnesium fluosilicate, magnesium formate, magnesium lactate, magnesium nitrate, magnesium nitrite, magnesium hypophosphate, magnesium selenate, magnesium sulfate, magnesium sulfite, magnesium thiosulfate, calcium butyrate, calcium chlorate, calcium chloride, calcium hypochlorite, calcium chromate, calcium formate, calcium gluconate, calcium lactate, calcium maleate, calcium nitrate, calcium nitrite, calcium propionate, calcium l-quinate, calcium sulfide, calcium di-thionate, calcium thiosulfate, calcium valerate, and mixtures of these salts.
  • the above list is not all inclusive and the magnesium or calcium salt is anyone which is water-soluble and provides magnesium or calcium ions in an aqueous system.
  • these salts include both inorganic and organic salts.
  • the magnesium or calcium salt can be supplied to the aqueous peroxy solution in the form of the magnesium or calcium salts of NTA and/or HEDP.
  • the novel, stabilizing agent can be in the form of (1) a three component combination of NTA, HEDP, and a magnesium or calcium salt (such as magnesium sulfate), or (2) a two component combination of the magnesium or calcium salts of NTA and HEDP.
  • the mole ratios of NTAzMg or Ca saltzHEDP be in the range of from about 1:1:1 to about :3:1, preferably from about 2:121 to about 2:2:1.
  • textile material includes any natural and/or synthetic fibrous base material such as cotton, nylon, viscose rayon, polyester, e.g., Dacron, hemp, linen, jute, and blends thereof such as, for example, cotton-Dacron, cotton- Dacron-viscose rayon,, cotton-nylon-viscose rayon, cotton-Dacron-nylon, cotton-nylon, and cotton-polyester (all in various weight ratios).
  • any natural and/or synthetic fibrous base material such as cotton, nylon, viscose rayon, polyester, e.g., Dacron, hemp, linen, jute, and blends thereof such as, for example, cotton-Dacron, cotton- Dacron-viscose rayon,, cotton-nylon-viscose rayon, cotton-Dacron-nylon, cotton-nylon, and cotton-polyester (all in various weight ratios).
  • the specific synthetic organic surfactant can be any of a wide variety of surface active agents. Typical surfactants are described in U.S. 2,846,398 and U.S. 3,159,581, both of which are incorporated herein by reference. Furthermore, other publications which describe surfactants which can be used in the present invention processes include Schwartz and Perry, Surface Active Agents, Interscience Publishers, New York (1949) and The Journal of American Oil Chemists Society, vol. 34, No. 4, pages 170-216 (April 1957), both of which publications are incorporated herein by reference. The amount of surfactant will vary, depending upon various process conditions and any amount can be used as long as no substantial adverse effect is incurred in the bleaching operation.
  • Peroxy solutions which are capable of being stabilized in addition to hyrogen peroxide and its addition compounds, such as the peroxide of sodium and the super oxide of potassium include urea percompounds, perborates, per sulfates, and the peracids such as persulfuric acid, peracetic acid, peroxy monophosphoric acid and their water-soluble salt compounds such as sodium, potassium, ammonium and organic amine salts.
  • the pH of the aqueous peroxy solution is usually adjusted with any caustic material in order to effect a pH of greater than 7, e.g. inorganic alkali metal basic materials, such as sodium hydroxide, sodium carbonate, sodium silicate, diand tri-sodium phosphates and the like, including mixtures of these as Well as the potassium forms of the foregoing materials, to a pH of between about 7.5 and about 12.5.
  • inorganic alkali metal basic materials such as sodium hydroxide, sodium carbonate, sodium silicate, diand tri-sodium phosphates and the like, including mixtures of these as Well as the potassium forms of the foregoing materials.
  • the pH is higher than about 12.5 rapid bleaching occurs and the peroxy-compounds rapidly decompose so that it is difficult to control a proper bleaching rate without undue damage to the fibers.
  • the rate of bleaching in most cases is slow to the extent of being uneconomical for bleaching.
  • the amounts of caustic used are from about 1% to about 4% by weight based on the total weight of the alkaline aqueous (peroxy) solution.
  • concentration of peroxy solutions can vary depending upon, inter alia, the type of peroxy-compound, pH, temperature, type of bleaching desired and the like, however, normal concentrations, i.e., from about 0.01 to about 5% can be used with concentrations from about .2 to about 3% being preferred. It is to be understood that the concentration is not a limitation herein and that any concentration can be utilized as long as the desired end result is achieved.
  • the stabilizing agents of the present invention may be dissolved in the peroxy solution which is ready for use or may be incorporated in a concentrated peroxy solution, such as a 35% solution of hydrogen peroxide, which is usually further diluted to form the peroxy solution for bleaching.
  • the stabilizing agent can be incorporated in dry bleach compositions, such as perborate compositions, by admixing therewith, and the resulting composition dissolved in the aqueous system immediately preceding its end use application.
  • the stabilizing agent is intended to be used with the peroxy solution at the time of its use for bleaching purposes.
  • the concentration of the stabilizing agent of the present invention in the peroxy solution can vary depending upon, inter alia, concentration of the peroxy solution, type of peroxy-compound used, pH, temperature and the like, and usually for normal concentrations of peroxy solutions and with conventional bleaching methods, the stabilizing agent is preferably present in concentrations from about 0.001 to about 5% with from about 0.1% to about 1% being especially preferred.
  • the methods for bleaching using the peroxy solutions containing the stabilizing agents of the present invention vary widely, as for example, from using the peroxy solutions at normal temperatures, i.e. from about 20 C. to about 35 C. and contacting the textile material by immersion for periods of time of several hours, i.e., from about 12 to about 36 hours, to using the peroxy solutions at temperatures from about 70 C. to about C. for periods of time from about 30 minutes to about 6-8 hours, as well as continuous bleaching methods which entail the use of the peroxy solutions at normal temperatures, i.e., about 25 C. and contacting the textile material by saturation, removing the excess moisture and exposing the textile material to saturated steam at temperatures from about 100 C. to about C.
  • U.S. Pats. 2,839,353, 2,960,383, and 2,983,568 are illustrative of being representative of continuous peroxy bleaching methods.
