Definitions

  • the novel and advantageous process of treating laundry comprises predrying the washed and rinsed laundry to a predetermined degree of dryness such as to a moisture content between 5 and 70 percent and preferably to a moisture content of about 15 percent, subjecting the predried laundry, preferably in a laundry drier, to the action of laundry treating agents, such as brighteners, antistatic, softening, aromatizing, and the like agents, preferably by spraying said agents thereon. and completing drying of the laundry. Thereby. any moldy smell of the laundry and/or its becoming electrostatically charged are eliminated and/or the properties of the finished laundry are considerably improved. Drying is preferably effected in laundry dryers of the tumbler type and the treating composition is preferably sprayed on the laundry in aerosol form.
  • a predetermined degree of dryness such as to a moisture content between 5 and 70 percent and preferably to a moisture content of about 15 percent
  • laundry treating agents such as brighteners, antistatic, softening, aromatizing, and the like agents
  • the present invention relates to a process of treating laundry in laundry driers and more particularly to a process of treating the laundry in such driers in order to eliminate the undesired moldy, typical laundry smell and/or electrostatic charging of the laundry.
  • laundry driers socalled tumblers, which are controlled, regulated, and operated electronically and/or in dependence on the drying time, have been marketed.
  • tumblers which are controlled, regulated, and operated electronically and/or in dependence on the drying time.
  • the washed laundry can be dried so that, after being centrifuged in the automatic washing machine, it is ready for ironing or can be placed into the linen closets or storage rooms.
  • the laundry was additionally subjected, after having been washed and rinsed usually four to five times in the wash ing machine to a so-called softening rinsing procedure.
  • softening rinsing procedure preferably cation active and/or nonionogenic agents, emulsifiers, perfumes, optical brighteners or clarifying agents, deodorants, and coloring agents were added to the rinsing water.
  • cation active and/or nonionogenic agents, emulsifiers, perfumes, optical brighteners or clarifying agents, deodorants, and coloring agents were added to the rinsing water.
  • Part of said agents get on or become attached to the laundry and are supposedto prevent the above-described disadvantages on subsequently drying the laundry in the laundry drier.
  • no satisfactory results could be achieved by proceeding in this manner because said agents most of which are readily volatile were separated and removed from the laundry during drying by the air current which passes through the tumbler.
  • Another object of the present invention is to provide a simple and effective device for carrying out said process.
  • the process according to the present invention comprises the step of applying the treating solutions or emulsions of agents for treating laundry as they are known per se in the laundry drier or turn bler after the laundry has attained a predetermined degree of dryness.
  • the above-described disadvantages of the known processes are avoided.
  • solutions or emulsions of the laundry treating agents are sprayed upon the laundry whereby the spraying operation is automatically initiated by a timing impulse or as soon as a predetermined degree of dryness of the laundry is attained.
  • an aerosol can or container at any place readily accessible to the operator.
  • Said aerosol can is connected by means of a suitable pipeline with a nozzle which is in direct connection with the inner space of the drying drum.
  • a valve is actuated at a predetermined moment by means of an electrical or mechanical impulse so that the treating agents are sprayed into the rotating or tumbling laundry.
  • the moisture content of the laundry should amount to between about 5 percent and about 70 percent and most advantageously to about 15 percent.
  • the process according to the present invention has the great advantage in contrast to the heretofore known processes that the agents used for treating the laundry are directly applied in the desired concentration to the laundry without any loss of active agent. As a result thereof, the effectiveness of the treating agents is fully preserved and the disadvantages of the known processes are not encountered.
  • All agents can be used in the process of the present invention that are able and required to improve the quality of the laundry, such as cation-active and/or non-ionogenic agents, antistatic agents, perfumes, deodorants, optical brighteners, dyestuffs, and others.
  • the cationactive and/or non-ionogenic agents used in the treatment of textiles according to the present invention cause formation of layers and preferably of monomolecular layers of said agents on the textile fibers and thus produce a sliding effect of the fibers with respect to each other. Said layers improve also sliding of the textile fibers on the skin of the person wearing the laundered lingerie 0r garment. As a result thereof, a positive feel and a pleasing fall of the textile material will be achieved and subsequent ironing will be facilitated.
  • the layers have a pronounced cl feet of dissipating static electricity and the textiles can be more readily laundered.
  • Numerous cation-active and/or non-ionogenic agents can be used for this purpose.
  • Especially suitable agents of this type are: 5
  • R is preferably a higher saturated fatty acid such as stearic acid or palmitic acid.
  • Fatty acid sarkosides (this agent is an anionic agent but can also be used in the claimed process) of the formula RCO-N(CH3)CH COONa wherein R preferably is higher alkyl derived from a saturated fatty acid.
  • R is higher alkyl
  • Suitable optical brightening agents are, for instance. derivatives of 4,4'-diamino stilbene-2,2-disulfonic acid, in which the amino groups are substituted by triazinyl or other basic groups or by acyl groups. such as acetyl, phenoxy acetyl or alkoxybenzoyl groups. Ureido substituted diamino stilbene disulfonic acids are also useful for this purpose.
  • Azoles such as monoazoles in the form of their sulfonic acids or bisazoles, such as bis-naphthotriazolyl compounds are also useful optical brighteners, likewise coumarin derivatives. Such optical brighteners are described, for instance, in Kirk-Othmer Encyclopedia of Chemical Technology Second Edition, volume 3, pages 737 to 749.
  • Especially useful quaternary ammonium compounds are, for instance, dimethyl benzyl cetyl ammonium chloride, dimethyl distearyl ammonium chloride, and the like compounds which in aqueous solution have not only a germicidal effect but also act as deodorants because they inhibit the production of malodors due to the action of micro-organisms and, therefore, are useful odor cont rolling agents.
  • Perfumes act as malodor counteracting and masking agents without involving any chemical changes. They also have a deodorizing and/or odor modifying effect. Any suitable perfume may be used, whereby, of course; the preferred perfumes are those which do not stain and do not cause discoloration of the laundry. Especially useful are the perfumes of the floral group, imparting flower odors to the laundry, as well as those of the herbal group imparting thereto the odor of hay and grass, clover, and the like. Lavender fragrances or the fragrances of citrus fruits may, of course, also be applied to the laundry.
  • Suitable deodorants are, for instance, phenolic polyoxymethylene derivatives, quaternary ammonium compounds, formaldehyde derivatives, 2,4,4 -trichloro-2- hydroxy diphenyl ether, 3,4,4-trichloro carbanilide, alkylolamides of undecylenic acid, and others.
  • Antistatic agents are added especially when washing synthetic fiber materials.
  • antistatic agents know, such as polyhydric alcohols, for instance, glycerol; amines, for instance, triethanolamine; amides, for instance, N,N-bis-(2-hydroxy ethyl) stearyl amide; polyoxy ethylene derivatives, for instance, hexadecyl ethers of polyethylene 'glycols; amine soaps, for instance, the soaps of stearic acid and octadecyl amine; amine salts of alkyl sulfates, for instance, the salts of guanidine and octadecyl sulfate; quaternary ammonium compounds, for instance, octadecyl trimethyl ammonium chloride; alkyl phosphates, for instance, bisdodecyl hydrogen phosphates; amine salts of alkyl phosphonic acids, for instance, the salts of
  • An aerosol composition which has proved to be useful for carrying out the present invention may have the following composition:
  • pecially a lower alcohol or a halogenated alkane pecially a lower alcohol or a halogenated alkane.
  • the preparations used for treating the partly dried laundry need not contain all the above mentioned groups of active agents. Their composition can be varied considerably; for instance, if a special softening effect is to be achieved, the predominant component of the preparation is the softening agent while the other agents may be omitted or added only in relatively small amounts.
  • the preparations may specifically contain a perfume or an aromatizing agent if a pronounced aromatizing effect is desired, or such agents may be omitted completely, for instance, when laundering hospital linen.
  • the treatment with the treating solution should be effected as early as possible, i.e., with laundry of a relatively high moisture content because then optimum distribution of the active agents over and throughout the laundry will be achieved due to the extended drying and thus treatment time.
  • the treating solution should be applied as late as possible, i.e., when the moisture content of the laundry is very low and thus its degree of dryness is high. Thereby optimum utilization of the treating agents will be achieved and, at the same time, the optimum amount of perfume will adhere to the laundry.
  • the treating solution is applied to the laundry at a moisture content between about 5 percent and about percent and preferably at a moisture content of about 15 percent in order to meet both above mentioned requirements.
  • a moisture content corresponds to a degree of dryness between 95 percent and 30 percent and preferably of percent.
  • compositions according to the present invention without a propellant and to spray them into the dryer by the action of compressed air.
  • a solvent is then added to the composition such as, for instance, FREON TF" i.e., l,l,2-trichloro-l,2,2-trifluoro ethane and the like.
  • FIG. 1 illustrates a dosing device introducing an aerosol composition into the laundry drier by means of a nozzle and valve controlled by a timer.
  • the aerosol can 1 is placed into the holding device 2 with an opening at its bottom through which the outlet 4 of the aerosol can 1 can be conneeted by means of adapter 3 to pipe 5.
  • the adapter 3 is designed so that it opens the valve of the aerosol can 1.
  • the electrically controlled valve 6 is provided in said pipe 5. Pipe 5 thus is under permanent pressure.
  • Pipe 10 leads from valve 6 to nozzle 7.
  • Valve 6 is also connected with timing device 8 which is either controlled by the moisture content of the air leaving the drier or by the moisture content of the laundry tumbling in said drier.
  • valve 7 is actuated for a certain period of time by an impulse issued from said timing device 8 so that a predetermined amount of active treating agent is sprayed into the dryer and onto the tumbling laundry through nozzle 7. If the aerosol can 1 becomes exhausted, it can easily be replaced by a new aerosol can. The entire dosing device is attached to door 9 of the drier.
  • the aerosol composition in the aerosol can 1 may be composed as described hereinafter in the Examples although it is not limited thereto.

  • the quaternary ammonium compound is then added thereto and the mixture is thoroughly emulsified in water of 60 C.
  • the optical brightening agent and the perfume are admixed thereto. Thereafter, 80 parts of said mixture are then filled with 20 parts of the propellant into suitable aerosol cans.
  • An aerosol can with about 350 g. of said mixture is sufficient for treating an average amount of laundry (35 kg. of dry laundry) in a laundry drier about 20 times.
  • the aerosol has a softening, bactericidal, and antistatic effect.
