of the product and will involve balancing the amount of sorbency desired with properties such as integrity or strength of the web or desired web thickness generally sorbent particles account for at least 1 and more typically at least 20 volume percent of the solid content of the sheet product 34 solid content 34 is used to contrast with bulk volume and refers to the physical components of the sheet product and not the voids or interstices between those components however amounts under 10 or 20 volume percent are useful and have the advantage that they are retained in the web even more completely than particles at higher loadings are retained where high sorbency is desired the sorbent particles generally account for at least 50 volume percent of the solid content of the sheet product one of the advantages of the invention is that high particle loadings can be achieved though there is seldom need for particles in excess of 90 volume percent sheet material of the invention has a variety of uses including uses listed in the prior art such as bandages diapers incontinent pads and sanitary napkins two sets of sheet product of the invention were prepared from polypropylene microfibers that averaged about 5 micrometers in diameter sorbent particles comprising a synthetic high molecular weight acrylic polymer containing hydrophilic carboxylate groups 34 permasorb 29 34 supplied by national starch and chemical corporation and surfactant particles of dioctyl ester of sodium sulfosuccinate 34 aerosol ot b 34 from american cyanamid the sorbent particles and surfactant particles in the amounts stated below were mixed together and introduced into a stream of the microfibers using apparatus as shown in fig1 the die orifices of the.
