Process of enhanced chemical bonding by electron beam radiation. |
摘要 |
<p>Permanent surface modification of polypropylene nonwoven fabrics is achieved through electron beam radiation induced chemical bonding. The electron beam energy levels suitable for such chemical bonding are between about 5 KeV to about 110 KeV at the surface of the fabric facing the electron beam radiation source. At these energy levels, chemical bonding, control of electron beam penetration and the formation of free radicals in the polypropylene nonwoven fabrics are achieved. Control of electron beam penetration produces free radical formation and chemical bonding at selective levels within the fabric as well as bonding of different chemicals asymmetrically to the same fabric with minimal, if any, loss of polymer fabric strength. <IMAGE></p> |
