Abstract
A method and apparatus for the production of nonwovens. The nonwovens including a spunbonding apparatus for forming a first web of nonwoven material on a first belt, and a meltblowing apparatus for forming a second web of nonwoven material on a second belt. The second belt moves in a direction opposite the first belt and after formation, the second web is deposited on said first web to form a composite spunbond and meltblown web.
Claims16
An apparatus for the production of nonwovens comprising:
- at least one spunbonding apparatus for forming a first web of nonwoven material on a first belt;
- and
- at least one meltblowing apparatus for forming a second web of nonwoven material on a second belt, said second belt depositing the second web on said first web to form a composite spunbond and meltblown web.
A method of forming a patterned nonwoven comprising the steps of:
- forming a first web of nonwoven material in a spunbonding process on a first belt;
- forming a second web of nonwoven material in a meltblowing process on a second belt;
- and
- combining said first and second webs of nonwoven material to form a composite nonwoven web.
An apparatus for the production of nonwovens comprising:
- at least one spunbonding apparatus for forming a first web of nonwoven material;
- at least one meltblowing apparatus for forming a second web of nonwoven material on said first web to form a composite spunbond and meltblown web;
- and
- a pattern drum for conveying a pattern to said composite web.
A method of forming a patterned nonwoven comprising the steps of:
- forming a first web of nonwoven material in a spunbonding process;
- forming a second web of nonwoven material in a meltblowing process on said first web;
- combining said first and second webs of nonwoven material to form a composite nonwoven web;
- and
- forming a pattern on said combined web by using a pattern drum.
