Definitions

  • the present invention encompasses articles for providing soil release, softening, odor, and antistatic benefits to fabrics in an automatic laundry dryer.
  • Treatment in an automatic clothes dryer has been shown to be an effective means for imparting desirable tactile properties to fabrics. For example, it is becoming common to soften fabrics in an automatic clothes dryer rather than during the rinse cycle of a laundering operation. (See U. S. Pat. No. 3,442,692, Gaiser, issued May 6, 1969).
  • Fabric « softness is an expression well-defined in the art and is usually understood to be that quality of the treated fabric whereby its handle or texture is smooth, pliable and fluffy to the touch.
  • Various chemical compounds have long been known to possess the ability to soften fabrics when applied to them during a laundering operation.
  • Fabric softness also connotes the absence of static « cling » in the fabrics, and the commonly used cationic fabric softeners provide both softening and antistatic benefits when applied to fabrics. Indeed, with fabrics such as nylon and polyester, the user is more able to perceive and appreciate an antistatic benefit than a true softening benefit.
  • soil release treatment of fabrics in an automatic clothes dryer is not as common as softening treatment.
  • European Published Application No. 0 071 148 discloses a product for imparting fabric softening and antistatic properties to fabrics in a rotary dryer, comprising an absorbent sheet substrate bearing a fabric softening quaternary ammonium salt. together with a condensation product of a fatty acid triglyceride with a hydroxyalkyl polyamine and other optional components, one of which can be a soil release polymer.
  • an article of manufacture adapted for providing fabric soil release and softening benefits within an automatic clothes dryer, said article comprising :
  • the fabric condition composition is releasably affixed on the substrate to provide a weight ratio of conditioning composition to dry substrate ranging from 10 : 1 to 0.5 : 1.
  • fabric conditioning composition as used herein is defined as a mixture of polymeric soil release agent and a fabric softening agent as defined herein.
  • the polymeric soil release agents useful in the present invention are those disclosed in the commonly assigned European Published Application No. 0185427 which forms part of the state of the art under Article 54(3) EPC.

  • the most preferred polymer is a solid at room temperature, has a softening phase transition temperature at or above 30 'C and becomes a flowable liquid below 100 'C, preferably below 90 'C.
  • the softening phase transition temperature can be determined by the differential scanning calorimetry method.
  • a polymer that is a hard solid at room temperature is desirable in order to keep the fabric conditioning sheets from having a tacky feel, while its softening and fluidity at higher temperatures facilitate the substrate coating process and the subsequent fabric conditioning active transfer from the fabric conditioning sheet to the fabrics in the clothes dryer at automatic dryer operating temperatures, i. e. 35 °C to 115 'C.
  • the polymeric soil release agent disclosed in the commonly assigned EP-A-0185427 has the formula : wherein the A moieties are essentially moieties ; the R 1 moieties are essentially 1,4-phenylene moieties ; and R 2 moieties are essentially ethylene moieties, or substituted ethylene moieties having C 1 -C 4 alkyl or alkoxy substituents ; the R 3 moieties are substituted C 2 -C 18 hydrocarbylene moieties having at least one -S0 3 M, -COOM, -0-[-R 5 O) m (CH 2 CH 2 O) n -]-X or -A-[-(R 2 -A-R 4 -A)-]- w -[-R 5 O) m (CH 2 CH 2 O) n -]-X substituent or at least one moiety -A-[-(R 2 -A-R 4 -A)-]- w R 2 -A- crosslinked to another
  • each R 1 is a 1,4-phenylene moiety ; the R 2 moieties consist essentially of ethylene moieties, 1,2-propylene moieties or a mixture thereof ; each X is ethyl or preferably methyl : each n is from about 12 to 43 and u is from 3 to 10.
  • a preferred polymeric soil release agent is POET (polyoxyethylene terephthalate), a compound with the general formula described hereinabove. It is synthesized from the following reactants :
  • reaction was carried out by adding all of the above to a 2 liter round bottom flask equipped with mechanical agitation. A 335 mm unpacked column was also fitted to the flask for methanol distillation. The system was placed under a nitrogen atmosphere and the temperature was gradually raised to 200 'C once the reaction mixture melted. Reaction conditions of 200 'C, atmospheric pressure, and constant mechanical agitation were maintained for 20 hours. To further drive the ester interchange reaction to completion, the reaction mixture was cooled to 130 'C, the methanol receiving flask was emptied, and vacuum was applied while concurrently introducing nitrogen sparge below the level of the liquid reaction mixture. An absolute pressure of 3.3 kPa (25 mm Hg) was obtained.
  • the resulting polymer was submitted to a three-solvent (short chain alcohols) extraction (IPA, EtOH, MeOH) and the EtOH, MeOH soluble fractions were combined in the ratio of 67 33.
  • IPA short chain alcohols

  • commercially available household one-ply toweling paper has a value of 5 to 6
  • commercially available two-ply household toweling paper has a value of 7 to about 9.5.
  • Using a substrate with an absorbent capacity of less than 4 tends to cause too rapid release of the fabric conditioning composition from the substrate resulting in several disadvantages, one of which is uneven conditioning of the fabrics.
