Pulp fibers are fed from the side into the air stream of a meltblown die, so the fine thermoplastic fibers wrap around and hold the pulp without a separate bonding step. The result is soft, bulky and absorbent, with the strength of the meltblown network. Coform is used mainly for wet wipes and absorbent products.
Coform line is running 65 percent pulp on the wipe base, and the lint complaints stopped once the MB air came up.
