made with deniers substantially different than the above described results difficulty can arise when using the latex containing the adhesive and the polymer material the polyester containing latex composition is prepared by taking a conventional latex of a material such a styrene butadiene an acrylic polymer a vinyl acetate resin a vinyl chloride resins or other suitable latex forming polymer and adding an amount of a polyester powder which is sufficient to impart good adhesive properties to the finished stiffener material saturated powdered polyesters such as polycaprolactone azelaic adipic sebacic and copolymers of polyethylene terephthalate and the like may be employed as substantially pure resins or in the form of commercially formulated adhesive compositions with conventional dispersants tackifiers stabilizers fillers and the like if the polyester is employed as a pure resin conventional dispersants such as non ionic surfactants gums colloids or thickening agents may be added to stabilize the latex containing the polyester in order to provide an adhesive which adheres to the non woven fabric without u201c dropping out u201d or in other words separating as a discrete powder on the non woven fabric it is preferred to grind the powdered polyester to a finely divided state which will remain dispersed on the non woven fabric when it is applied from a dispersion in a polymeric latex generally an average particle size of less than 150 microns and more preferably less than 100 microns will provide good results the u201c dropping out u201d phenomenon is usually observed when the process of the invention is practiced on a full scale commercial apparatus as compared to a laboratory scale operation ammonium.
