a) arranged in the web formed directly coordinated to the C- type fibers and b) more than 5% by weight of the directly formed fibers, including a new collected lump of staple fibers having a 15% or more crimped fiber formed directly dispersed in non-woven fiber web is taught. The web Lofty but no macropores. Preferably, the web has a light transmittance variation of less than 2% or more and about 50 non-filled. Typically, the fibers in the web are self-bonded at the fiber intersections preferably by a combination provides a resistance to compression matrix. The web is particularly useful for acoustic and thermal barrier. Fiber nonwoven web directly formed fibers and crimped staple fibers, C- shaped coordination, sound and heat insulation
