Definitions

  • the present invention relates to "superabsorbent" particles and their use to improve the in-wear comfort of fabrics, especially synthetic fabrics, by increasing fabric absorbency.
  • JP03220371 A discloses the coating of the surface of synthetic textile with a resin which contains particles of the silk protein "fibroin".
  • the fabric is tack- free and flexible and has high moisture-permeability. Excellent dry touch and quality is said to be produced at a fibroin content of 10-35 wt %.
  • JP2000110027A discloses the introduction of a fine clay particle e.g. montmohllonite during the preparation (polymerisation) of thermoplastic polyester, to give a water absorbing polyester. Preferably the clay is swollen with water and water replaced with glycol. Treated fabrics have good spinability, dyeability and softness.
  • JP08041783A discloses the application of a sizing agent (e.g. starch) to polyester before a high temperature shape-setting process is carried out. The sizing agent is removed with enzyme but the decomposition product allowed to remain on surface of fabric. The treated fabric has soft feeling and good water absorption properties by increasing space between fibers.
  • WO9849220A discloses a soft, hydrophilic fabric which has been treated with functionalised polyorganosiloxane.
  • a superabsorbent particle comprising a superabsorbent polymeric core and a hydrophobic porous shell in the domestic treatment of fabric, wherein the shell comprises silicone.
  • a non-aqueous fabric treatment composition for domestic use comprising superabsorbent particles and a solvent, wherein the superabsorbent particles comprise a superabsorbent polymeric core and a porous shell, wherein the shell comprises silicone.
  • composition of the second aspect of the invention to increase the moisture absorption of fabric.

  • a preferred cellulose-based superabsorbing polymer is Sodium Carboxy Methyl Cellulose (SCMC).
  • the shell prevents sticky feeling when the absorbent material is on the fabric.

Jacobs, edited by Van Nostrand; or Perfume and Flavor Chemicals by S.
  • perfume in this context is not only meant a fully formulated product fragrance, but also selected components of that fragrance, particularly those which are prone to loss, such as the so-called 'top notes'.
  • Top notes are defined by Poucher (Journal of the Society of Cosmetic Chemists 6(2):80 [1955]). Examples of well known top-notes include citrus oils, linalool, linalyl acetate, lavender, dihydromyrcenol, rose oxide and cis-3-hexanol.

  • Preferred non-encapsulated perfume ingredients are those hydrophobic perfume components with a ClogP above 3.
  • ClogP means the logarithm to base 10 of the octanol/water partition coefficient (P).
  • the octanol/water partition coefficient of a PRM is the ratio between its equilibrium concentrations in octanol and water. Given that this measure is a ratio of the equilibrium concentration of a PRM in a non-polar solvent (octanol) with its concentration in a polar solvent (water), ClogP is also a measure of the hydrophobicity of a material-the higher the ClogP value, the more hydrophobic the material.
  • ClogP values can be readily calculated from a program called "CLOGP" which is available from Daylight Chemical Information Systems Inc., Irvine Calif., USA. Octanol/water partition coefficients are described in more detail in U.S. Pat. No. 5,578,563.
  • Perfume components with a ClogP above 3 comprise: lso E super, citronellol, Ethyl cinnamate, Bangalol, 2,4,6-Thmethylbenzaldehyde, Hexyl cinnamic aldehyde, 2,6-Dimethyl-2-heptanol, Diisobutylcarbinol, Ethyl salicylate, Phenethyl isobutyrate, Ethyl hexyl ketone, Propyl amyl ketone, Dibutyl ketone, Heptyl methyl ketone, 4,5-Dihydrotoluene, Caprylic aldehyde, Citral, Geranial, lsopropyl benzoate, Cyclohexanepropionic acid, Campholene aldehyde, Caprylic acid, Caprylic alcohol, Cuminaldehyde, 1-Ethyl-4-nitrobenzene, Heptyl formate,

  • perfumes with which the present invention can be applied are the so-called 'aromatherapy' materials. These include many components also used in perfumery, including components of essential oils such as Clary Sage, Eucalyptus, Geranium, Lavender, Mace Extract, Neroli, Nutmeg, Spearmint, Sweet Violet Leaf and Valerian.

A control composition, containing pentane only were also applied to polyester and cotton samples. A pad mangle was used to apply the compositions (Vertical laboratory padder VFM type ex. Werner Mathis AG). Fabric samples were pad applied to 100% pick-up. The fabric samples were then dried in air.

  • Sofcare S-SP on polyester significantly increases the amount of moisture that can be absorbed, i.e. 8.8 % absorption compared with 0.6 % for untreated polyester.
  • a 10 % loading of Sofcare S-SP on polyester gives a greater absorbency than untreated cotton, i.e. 19.6 % compared with 13.5 %.
