Definitions

  • This invention relates to improvements in or relating to clothes washing.
  • Detergents of varying types have been on the market for many years. Over that period of time, the washing ability of detergents has been improving not only from the perspective of cleaning clothes but also from the perspective of providing additives which can have an effect on the clothes other than a cleaning effect.
  • detergents are now being produced which can have the same or a better cleaning effect at temperatures 50° C or below even down to so called "cold wash" where the water temperature can be as low as 20° C as compared with their earlier counterparts which required that clothes be washed at relatively high temperatures generally around 60° C.
  • detergents which are sold by what can be regarded as the brand leaders are relatively expensive compared with so-called own brand products. It is well known that consumers can regard some detergents, which are perceived to be less expensive, as not performing as well as the more expensive brands. Thus, detergent manufacturers have to strike a balance between producing product which is less expensive than the so called more expensive leading brands and the consumer's perception of quality. In order to maintain the same or equivalent cleaning power, particularly at relatively low temperature washing cycles, the comparatively lower cost detergents are less expensive because, quite often, they do not contain certain additives which are not essential for successful washing of the clothes but are desirable.
  • Such additives include, but are not limited to, chemicals which will impart a perfume on the washed clothes; or will comprise so-called whiteners which will provide the consumer with the experience that, in particular, white garments are not only clean but appear sparkling white; or anti-soil re-deposition agents to prevent unwanted matter in the laundry wash from being absorbed, reabsorbed or deposited on the clothes.

Abstract

L'invention concerne une lingette de lavage comprenant un substrat non tissé imprégné d'un azurant optique et/ou d'un premier agent empêchant la redéposition de salissures. Des exemples du substrat non tissé sont obtenus par voie humide, lacés par filage, filés-liés, obtenus par perforation d'aiguille ou obtenus par voie pneumatique. L'azurant optique peut être, par exemple, le 2,2'-([1,1'-biphényl]-4,4'- diyldivinylène)bis(benzènesulphonate) disodique. L'agent empêchant le re-dépôt de salissures peut être, par exemple, la polyvinylpyrrolidone. En outre, le substrat peut également être imprégné d'un pigment tel que la phtalocyanine de cuivre. En outre, le substrat peut également être imprégné d'un second agent empêchant la redéposition de salissures tel qu'un copolymère de polyester modifié.
