Claims20
A nonwoven fabric for forming an oral pouched product, the nonwoven fabric comprising a chemically bonded web of staple fibres, wherein the staple fibres comprise:
- a first component of fibres with a linear density equal to or greater than 0.9 dtex;
- and
- a second component of fibres with a linear density of less than 0.9 dtex.
A nonwoven fabric for forming an oral pouched product, the nonwoven fabric comprising a chemically bonded web of staple fibres, wherein the staple fibres comprise:
- a first component consisting of non-splitable fibres;
- and
- a second component consisting of split fibres.
A method of manufacturing a nonwoven fabric for forming an oral pouched product, the method comprising:
- mixing staple fibres that comprise splitable fibres and non-splitable fibres;
- splitting a proportion of the splitable fibres to form split fibres;
- forming a web of the staple fibres, the web comprising:
- a first component consisting of the non-splitable fibres;
- and
- a second component consisting of the split fibres;
- and
- applying a binder to the web to bond the staple fibres together.
