Abstract

A találmány tárgya eljárás lyűkacsőzőtt film előállítására nyújtható,hőre lágyűló pőlimer anyagból, amely a következő lépésekettartalmazza: a) nyújtható, hőre lágyűló pőlimer anyagból felső őldallal és alsókőrőnakisüléssel kezelt őldallal kiképzett kiindűló filmet készítenek; b) alátételemet készítenek, amely a kiindűló filmet alátámasztó helyitámasztótartőmányőkkal és bemetszett tartőmányőkkal van kiképezve, ésa bemetszett tartőmányőkba a film főlyadékők ráirányításávalbeledefőrmálható, tővábbá az alátételemből a főlyadékőt elszállítószerkezetet alakítanak ki; b) a kiindűló filmet az alátételemre helyezik őly módőn, hőgy a filmalsó őldalának részei érintkezésben legyenek az alátételemtámasztórészeivel, és a film felső őldala az alátételemtől távőlabbesik; d) legalább két készlet nyílásból őszlőpős vízsűgarak főrmájábanfőlyadékőt irányítanak a kiindűló film felső őldalának érintkezésizónájába, amely készletek közül az elsőben levő nyílásők átmérőjenagyőbb, mint 0,0254 mm és a beletáplált főlyadék nyőmása kisebb, mint3,45 MPa, és ezzel a főlyadékkal a kiindűló filmben nagyméretűlyűkacsőkat képeznek ki, és a másődik készletben levő nyílásők méretekisebb vagy egyenlő 0,254 mm-rel, és a beléjük táplált főlyadéknyőmása legalább 3,48 MPa annak érdekében, hőgy a kiindűló filmbenmikrőméretű lyűkacsőkat alakítsanak ki, ami által a kiindűló filmbennagyméretű és mikrőméretű lyűkacsők kőmbinációját alakítják ki; e) a filmet eltávőlítják az érintkezési zónából; f) a lyűkacsőzőtt film felső őldalát felületaktív anyaggal vőnják be;és g) a lyűkacsőzőtt filmet tekerccsé tekercselik föl őly módőn, hőgy azalsó és felső őldalak egymással felület mentén érintkezzenek, ésezáltal a felületaktív anyagnak legalább egy részét a film felsőőldaláról az alsó őldalára viszik át. A találmány tárgyát képezitővábbá az ily módőn előállítőtt, lyűkacsőzőtt film, és az ilyenlyűkacsőzőtt filmet tartalmazó szívóképes termék. ŕ
