Claims36
A tufted coform nonwoven web comprising a matrix of thermoplastic meltblown filaments and at least one secondary material, wherein the coform nonwoven web has a first exterior surface comprises tufts, each tuft comprising a matrix of the thermoplastic meltblown filaments and the at least one secondary material.
A method of preparing a three-dimensional tufted coform nonwoven web comprising:
- a. providing at least one stream comprising meltblown filaments;
- b. providing at least one stream comprising at least one secondary material;
- c. converging the at least one stream containing at least one secondary material with the at least one stream of meltblown filaments to form a composite stream;
- d. depositing the composite stream onto a shaped forming surface as a matrix of meltblown filaments and at least one secondary material to form a first deposited layer;
- e. optionally applying a pressure differential to the matrix while on the forming surface;
- and
- f. separating the nonwoven web from the shaped forming surface, wherein the nonwoven web comprises an array of projections and land areas corresponding to the shaped forming surface.
