Abstract

FIELD: textile industry. SUBSTANCE: material contains variety of thread-like fiber bunches which pass between knots and intersect them. These fiber bunches and knots form pattern from ports, mainly, square in shape. Each fiber bunch has fiber segments which are compacted and pressed. many fiber segments are parallel to one another in the fiber bunches. As can be seen from drawings, there is, in essence, entangled zone in the center of fiber bunches between adjacent knots where fibers tend to curve along the circumference round the periphery of the parallel pressed fiber segments. As it is seen, fiber bunches protrude from opposite sides out of entangled over circumference zone. This configuration in the present solution is preferable to the so-called arch bundle or zone with arch bundle. EFFECT: higher efficiency. 1 dwg

Material 50 comprises a variety of filamentous fiber clumps 51 that extend between and intersect nodes 52. These fiber clumps and nodes form a pattern of windows 53, the windows being mostly square in shape. Each of the fiber clumps contains fiber segments that are densified and compressed. In these fiber clusters, many of the fiber segments are parallel to each other. In the center of the fiber bundles between adjacent nodes there is a subsequently tangled zone 54, where the fibers tend to wrap around the circumference around the periphery of parallel pressed fiber segments. As you can see, the fiber clumps protrude from opposite sides of the tangled around the zone. This configuration in the present solution is preferred over the so-called "arc ligament" or "zone with an arc ligament." 1 ill.
