Definitions

  • the present invention relates to fabric softening compositions that not only provide excellent fabric softening benefit but also protect the fabric, especially wool fabric, from felting.
  • the fabric softening composition contains, in addition to common ingredients found in such compositions, at least one thickener that is substantive to the fabric, a fabric softening silicone compound and at least one protein or derivative thereof.
  • the object of the present invention is to provide a fabric conditioner composition which not only provides excellent fabric softening benefit but also protects the fabric, especially wool fabric, from felting.
  • Felting is the process whereby fibres, in particular wool fibres, become impossibly matted. In particular it can be a problem with the use of warm/hot "soapy water" during the washing process, which opens up the wool fibre structure. When the wool fibres are cooled in the rinse cycle this can lock the fibre structure into a matted state.
  • Clearly a product that can protect against felting, especially during the rinse cycle has a major benefit in helping garments retain their original size and finish.
  • compositions preferably have a medium to high viscosity (by medium to high viscosity we mean from 50 to 50,000 cps, preferably from 100 to 1,500 cps, as measured using a Brookfield LVT viscometer, spindle no. 2 at 12 rpm and at 20°C.

  • the silicone materials employed as the antifoam agents herein can be alkylated polysiloxane materials of several types, either singly or in combination with various solid materials such as silica aerogels and xerogels and hydrophobic silicas of various types.
  • the present invention also encompasses a method for treating fabric, especially wool or mixed wool fabric, which comprises the step of contacting said fabric in a rinse cycle of a fabric washing machine with an aqueous medium containing a composition as defined hereinbefore.
  • the aqueous medium is at a temperature between 2 to 40 °C, more preferably between 5 to 25 °C.
  • the present invention also comprises the use of a composition as defined hereinbefore in the prevention of felting of wool or mixed wool fabric during the rinse cycle of a fabric washing process.
  • test machines of the same model are used for the test.
  • the test conditions described are controlled before to start the test for each of the four washing machines.
  • the towels are changed between the machines so that each product is used equally in each of the four washing machines. In this way all test swatches undergo the same treatment.
  • the washing machines are loaded with ballast and test swatches, paying attention to use the same procedure for all the products.
  • the detergent is added as normal, according to the label instructions.
  • the test fabric conditioner added into the rinse cycle.
  • test swatches are line dried.
  • test swatches which undergo more than one wash are line dried between each wash cycles before the assessments. Evaluation
  • test swatches which undergo more than one kind of assessments the order of the evaluation must be the following: instrumental evaluation, visual evaluation and lastly feel of fabrics.
  • the softness evaluation (feel of fabrics) is measured by means of a panel test.
  • a panel of at least five trained techmcians was used. Softness evaluations are carried out after three, five, ten, fifteen and twenty repeated wash cycles.
  • the degree of shrinkage is reported as % of reduction of surface area.
  • Luw length unwashed swatch
  • the degree of felting is measured by means of a panel test. A panel of at least five trained technicians is used obtain reliable result. The samples washed were compared to each other, using the corresponding unwashed fabric sample as a reference, according to the following scale:
