Definitions

  • the present invention relates to a method for providing good in-wear comfort, in particular on the skin contacted with the treated fabric.
  • Softening compositions have long been known in the art and are widely utilized by consumers during for example the rinse cycles of automatic laundry operations.
  • fabric softening refers to a process whereby a desirably soft hand and fluffy appearance are imparted to fabrics.
  • Typical of such softening compositions comprise softening compounds like ditallowdimethylammonium chloride, and di-(tallowyloxyethyl) dimethyl ammonium chloride.
  • the conventionally known softening compositions have been used to reduce the harshness and wearing-out after multiple cycle to reduce the side effect of the laundry process coupled with environmental effects, e.g. water hardness.
  • the softness of the garment and consequently the reduction of the mechanical friction between the garment and dry skin is obtained.
  • WO 98/03 619 discloses a liquid fabric softening compositions comprising softener actives including di- and triesters of quaternary ammonium compounds having a cloud point between 11.2°C and 34°C.
  • the detergent formulator is thus faced with the challenge of formulating a product which provide good in-wear comfort, that is which maximises the thermophysiological aspect of the clothes but minimises the friction on wetted skin, i.e. minimises the hydrophobilisation of the treated fabric surface whilst still providing a good softness perception of the fabric to the consumer.

  • the softening compound maintains the balance between the air, heat (or temperature) and moisture on the skin, thereby delivering a better climate control for the clothes as well as for the skin (body) that are contacted with the treated fabric. Consequently, the skin can breathe and so does the cloth as the cloth absorb moisture away from the skin, i.e. the treated fabric provides a thermal absorbency that reacts to the body's changing needs.

  • the above polymer for use herein it most preferred that they have a molecular weight in the range as described herein above. This range is typically higher than the range for polymers which render only dye transfer inhibition benefits alone. Indeed, the high molecular weight enables the abrasion occurring subsequent to treatment with the polymer to be reduced, especially in a later washing procedure. Not to be bound by theory, it is believed that that this benefit is partly due to the high molecular weight, thereby enabling the deposition of the polymer on the fabric surface and providing sufficient substantivity that the polymer is able to remain adhered to the fabric during the subsequent use and washing of the fabric. Further, it is believed that for a given charge density, increasing the molecular weight will increase the substantivity of the polymer to the fabric surface.
  • the balance of charge density and molecular weight will provide both a sufficient rate of deposition onto the fabric surface and a sufficient adherence to the fabric during a subsequent wash cycle.
  • Increasing molecular weight is considered preferable to increasing charge density as it allows a greater choice in the range of materials which are able to provide the benefit and avoids the negative impact that increasing charge density can have such as the attraction of soil and residue onto treated fabrics. It should be noted however that a similar benefit may be predicted from the approach of increasing charge density while retaining a lower molecular weight material.
