A pouched through the washer and dryer laundry additive product having at least one of its walls constructed of finely apertured polymeric film. In a particularly preferred embodiment, both pouch walls are constructed of finely apertured polymeric film to permit substantially full dissolution and discharge of the washer additive contained in the pouch during the washing cycle, yet retain substantially all of the dryer additive until the product is transferred into an automatic clothes dryer along with the laundered textiles. Pouched through the washer and dryer laundry additive products of the present invention deliver a significantly greater quantity of dryer additive material onto the textiles being tumble dried when contrasted with comparably constructed pouches comprised entirely of nonwoven and/or paper material. Furthermore, pouched through the washer and dryer laundry additive products of the present invention accomplish the aforementioned objective without an accompanying increase in staining of the textiles by the dryer added materials. Subcombination dryer additive products which contain no washer additive, but which are capable of withstanding a wash cycle without adversely affecting their performance in the dryer are also disclosed.

A pouched through the washer and dryer laundry additive product for distributing a substantially predetermined quantity of washer additive into the water during the wash cycle and for applying a substantially predetermined quantity of dryer additive substantially uniformly onto the surfaces of the laundered textile articles during the tumble drying cycle, said laundry additive product comprising: (a) a predetermined quantity of particulate water soluble washer additive; (b) a predetermined quantity of particulate dryer additive which is substantially insoluble in water, said particulate dryer additive having a softening temperature which is greater than the temperature of the wash water, but less than the temperature normally encountered in an automatic clothes dryer; and (c) a pouch formed from at least two pliable opposing walls, said pouch including at least one discrete compartment formed by said pliable opposing pouch walls, at least one of said pliable opposing pouch walls being comprised of substantially water impermeable synthetic polymeric film which has a softening temperature greater than the maximum temperature to which it will be exposed during the washing and drying cycles, said film also being substantially nonabsorbent to said washer additive and said dryer additive, said compartment totally enclosing said particulate washer additive and said particulate dryer additive, said polymeric film pouch wall further exhibiting a pattern of protuberances which are outwardly oriented relative to the interior of said compartment, each of said protuberances exhibiting an aperture at its tip, each of said apertures being of substantially predetermined size, said pattern having a density in the range of between about 1,600 and about 14,400 apertures per square inch, substantially all of said apertures in said polymeric film pouch wall exhibiting a maximum cross-section which is small enough to prevent the bulk of said particulate washer additive and the bulk of said particulate dryer additive from passing therethrough so long as they remain in a substantially dry, solid state, said apertures in said polymeric film pouch wall also being large enough to permit said wash water to enter said pouch, dissolve said particulate washer additive and form a wash liquor which thereafter exits said pouch through said apertures during said wash cycle without dissolving said substantially water insoluble particulate dryer additive, said apertures in said polymeric film pouch wall also functioning during the tumble drying cycle to substantially uniformly distribute said dryer additive onto the surfaces of the laundered textiles which come in contact with said apertured pouch wall during the tumble drying cycle while said dryer additive is in a softened and viscous state.
