History of American textiles : with kindred and auxiliary industries (illustrated) . icof textile manufacture that no mechanicalmethod expressed by pressure has been de-vised for filling them, while chemical re-actions involving the deposition of a water-repellent substance served at most only tocoat or veneer the fibre, leaving the capil-lary pores in condition to resume their ab-sorptive functions when the veneer or coat-ing was either partially or wholly destroyed. hydroxid by a method involving the use ofa series of electrolysed rolls between which,after preparation with suitable reagents, thefabrics are passed. Chemical reactions thus induced occurunder the influence of an amplified osmoticpressure due to an electric current flowingthrough the fabric from a positive to a nega-tive roll, which causes penetration of thefibre pores by the insoluble salts formedduring the critical period of electric fillings cannot be removed by ex-ternal friction which may be exerted to thepoint of abrasion without affecting are so minutely concealed, and the. The Original Tate Electrolytic Waterproofing Machine It was obvious that if these minute absorbentpores of the fabric could be filled with apermanent water-repellent substance, whichshould in no way impair the quality of ven-tilation, the object sought would be ob-tained. And to maintain the quality of ven-tilation it was imperative that only theseminute pores of the fibre be filled, and notthe interstices of the fabric itself, caused bythe multi-fibred threads as they cross eachother in the warp and weave. After a longperiod of experiment involving the use ofthe principle that an electric current gener-ates in fluids the force or pressure knownas electric osmosis, Mr. Tate succeeded infilling these microscopic pores with a com-bination of insoluble metal palmitate and repellent nature of their substances is suchthat they will withstand the supremelysevere test of molecular friction induced byboiling
