Definitions

  • This invention relates to a method for the treatment of fibrous material and more particularly to a method for reducing the tendency of fibrous materials to discolor or darken when cured at elevated temperatures in the resence of an alkalizing agent.
  • a number of alkaline heat-curing methods for fibrous materials are known, as for example treatments involving the application of certain crease-proofing or wash-andwear agents, reactive dyestuffs and other functional substances.
  • a chemical reaction takes place between the treating agent (including reactive dyes) and the fiber as a result of which the agent becomes chemically bound to the fiber.
  • an alkalizing agent or alkaline-reacting material is employed as a catalyst, acid-binding agent, or for some other purposes.
  • the color produced by the action of the alkaline material in such heat-curing methods may be destroyed or eliminated by bleaching, as with oxidizing agents such as hydrogen peroxide, sodium hypochlorite and the like.
  • oxidizing agents such as hydrogen peroxide, sodium hypochlorite and the like.
  • Sodium hypochlorite solution performs better than hydrogen peroxide in this bleaching operation but it is less desirable because of undesirable side reactions which may occur.
  • cross-linking agents for crease-proofing, water repellency, etc.
  • optical brighteners or reactive dyestuffs for example, in the dyeing of fibers with reactive dyestuffs, or in the simultaneous treatment of fibers with cross-linking agents (for crease-proofing, water repellency, etc.) and optical brighteners or reactive dyestuffs, the
  • -brightener and/ or dyestuff may be more or less destroyed by the oxidizing bleaching agent. If the amount of color produced during such alkaline heat-curing method is too large, it becomes too difficult to bleach with oxidizing agents such as hydrogen peroxide, the bleaching operation becoming too time-consuming and commercially unfeasible.
  • Another object of this invention is the provision of an alkaline heatcuring method for fibrous materials with a reduced tendency to discoloration.
  • Still another object of this invention is the provision of a process involving treatment of fibrous materials in an alkaline medium followed by drying and heat-curing the treated fibrous materials which process has a reduced tendency to discolor the 3,498,736 Patented Mar. 3, 1970 fibrous materials.
  • the present invention which is based upon the discovery that when the heat-curing step is carried out in the presence of a boron-containing compound, the above described tendency of the fibrous material to discolor is unexpectedly reduced or eliminated. More particularly, the invention broadly comprises the step of heat-curing fibrous material in the presence of an alkalizing agent and a boron-containing compound at a temperature of at least about 250 F. It has been unexpectedly found that even when the use of a boron-containing compound in the alkaline heat-curing of fibrous materials does not completely eliminate color formation, the minimizing effect is great enough to permit commercially practical bleaching of residual color with oxidizing agents such as hydrogen peroxide or oxidizing agents that do not cause undesirable secondary degradations.
  • oxidizing agents such as hydrogen peroxide or oxidizing agents that do not cause undesirable secondary degradations.

  • boron-containing compounds are the borohydrides of the same cations as referred to in the preceding paragraph with respect to the borates. Those preferred are the alkali metal borohydrides, particularly sodium borohydride.
  • the invention is effected by adding the boron-containing compound to the aqueous alkaline medium containing the functional agent (e.g. brightener or reaciive dyestuff, cross-linking, crease-proofing, wash and wear agent, etc.) in an amount sufficient to obtain the desired reduction in discoloration. This amount will be readily ascertainable in any particular instance by routine experimentation.
  • the functional agent e.g. brightener or reaciive dyestuff, cross-linking, crease-proofing, wash and wear agent, etc.
  • the optimum amount to be employed in any particular instance will depend upon the particular boron-containing compound employed, the functional agent being applied to the fibrous material, the result desired, etc.
  • the borohydrides are extremely effective in relatively small amounts in the lower part of the aforementioned range, and may be employed in proportions of about 0.03 to 0.08% in the aqueous alkaline medium.

It imparts wet and dry crease resistance in addition to increased resistance to washing, laundry sours, mildew damage, moth damage, shrinkage, chlorine retention, odor and/ or dyeing.
  • the present invention is carried into effect by adding the boron-containing compound to the aqueous alkaline medium, in the form of a solution, emulsion, suspension or other type of dispersion, containing the desired amount of crease-proofing agent.

  • Sodium carbonate or bicarbonate is preferred for this purpose.
  • the aqueous medium may be applied to the fibrous material .by immersion, padding, spraying, printing or any other desired manner, continuously or otherwise. For overall effects, it is preferred to apply an excess of the aqu ous alkaline medium fo o e by a squeez g step with a liquor pick-up of about 30% or less to or more by weight of the fiber.

Too high a curing temperature and/or duration causes fiber damage and is to be avoided. These maximum permissible conditions are readily determinable in any instance.

  • Example I Cotton print cloth (80 x 80) was padded through an aqueous solution containing 2% sodium carbonate, 12.5% 2,2'-sulfonyldiethanol and 0.2% sodium tetraborate deca-hydrate (Na B O -10H O), commonly known as borax. The pressure on the squeeze rolls had been previously adjusted so that the pickup of the solution was 80% of the weight of the fabric. The fabric was dried and then subjected to heat-curing for three minutes at 300 F.
