Abstract 1. A METHOD FOR PRODUCING A FLEXIBLE GAS PERMEABLE NONWOVEN MATERIAL CONSISTING OF AT LEAST ONE WEB OF SPLIT FIBERS WHICH COMPRISES ARRANGING SIDE BY SIDE THE SPLIT FIBERS OF AT LEAST ONE WEB OF SPILT FIBERS HAVING A NETWORK STRUCTURE, ELONGATED LENGTHWISE WITHOUT SUBSTANTIAL SLACKING AND SUBSTANTIALLY PARALLEL TO EACH OTHER; LAYING ON THE SAID WEB OF SPLIT FIBERS A PREFORMER SOLID SHAPED PATTERN OF ADHESIVE BINDER POLYMER WHICH COVERS THE SURFACE OF THE SAID WEB OF SPLIT FIBERS ONLY LOCALLY THOSE PORTIONS OF SAID WEB WHICH UNDERLY SAID SHAPED PATTERN OF ADHESIVE AND; THEREAFTER PRESSURE ADHERING THE RESULTING ASSEMBLY TO BIND SAID ADHESIVE AND SAID WEB SO AS TO LEAVE LOOSE AND UNFIXED PARTS AMIDE FIRMLY FIXED FIBER PARTS, SAID SHAPED ADHESIVE BINDER HAVING A SOFTENING TEMPERATURE RANGE LOWER THAN THE HEAT RESISTING TEMPERATURE OF SAID WEB SAID PRESSURE-ADHERING BEING EFFECTED BY HEATING SAID MATERIALS AT A TEMPERATURE LOWER THAN THE HEAT RESISTING TEMPERATURE OF THE SAID WEB BUT WITHIN THE SOFTENING TEMPERATURE RANGE OF THE SAID ADHESIVE BINDER.
