Processing of chemically modified cellulosic fibres

A chemically modified cellulosic fibre or filament having a moisture content of at least 7% by weight obtained by a process comprising the steps of (i) obtaining cellulosic fibres or filament and chemically modifying the cellulose by substitution to increase its absorbency; (ii) washing the fibres after step (i) in a mixture comprising water and up to 99% by weight of water-miscible organic solvent; (iii) drying the fibres to a moisture content of at least 7% by weight.

A PACKAGING MATERIAL AND AN ORAL POUCHED SNUFF PRODUCT
20220112638 · 2022-04-14 ·

The present invention relates to a packaging material for use in an oral pouched snuff product in order to enclose a smokeless tobacco composition or non-tobacco composi¬tion. The packaging material is a saliva-permeable nonwoven comprising carded fibres, whereof 0%-95% of the carded fibres are of a first type and 5%-100% are of a second type. The fibres of the first type are cellulose-based staple fibres. The fibres of the second type are thermoplastic fibres, comprising a first component and a second component, the second component having a lower melting temperature than the first component. The packaging material is bonded by means of at least partial melting and/or softening of the second component of the fibres of the second type and has a smooth-calendered surface.

The present invention also relates to an oral pouched snuff product comprising such a packaging material.

Nonwoven Fabric Including Fibers Formed from Post-Consumer Recycled Plastic
20220042222 · 2022-02-10 ·

Nonwoven fabrics are provided that include a mechanically entangled blend of fibers comprising (a) post-consumer recycled polymer staple fibers (PCR-staple fibers) and (b) one or more additional fibers, in which the one or more additional fibers are different than the PCR-staple fibers. The PCR-staple fibers are mechanically entangled with the one or more additional fibers to define the nonwoven fabric.
