A smokeless tobacco product includes smokeless tobacco and structural fibers. The structural fibers forming a network in which the smokeless tobacco is entangled. The structural fibers have a composition different from the smokeless tobacco. The tobacco-entangled fabric can have an overall oven volatiles content of at least 10 weight percent. In some embodiments, the structural fibers form a nonwoven network. In some embodiments, fibrous structures of the smokeless tobacco are entangled with the structural fibers.

A self-bonded nonwoven web, at least some cellulosic fibers that are self-bonded to each other at points of intersection of the cellulosic fibers with each other; and, an ionic liquid. Methods of making such a web are also disclosed, wherein the method comprises: contacting at least some of the first, cellulosic fibers with an ionic liquid; exposing the ionic liquid and the first, cellulosic fibers to a first temperature; and exposing the ionic liquid and the first, cellulosic fibers to a second temperature that is lower than the first temperature.

A meltblown method for producing nonwoven fabrics with hygroscopic metastatic feature. Firstly, fuse prepared bio-polyamide 6,10 into a melt, then extrude, and blow the melt out spinnerets to form natural bio-polyamide 6,10 filaments laid onto a conveyer to form a substrate fibrous web. Secondly, blend and dissolve prepared pulp by putting N-methylmorpholine N-oxide (NMMO) dissolving solvent, and dehydrate it to form dope, then extrude and blow the dope out spinnerets to form natural cellulose filaments laid up over existing fibrous web of bio-polyamide 6,10 on the conveyer so that a fibrous composite of the bio-polyamide 6,10 and natural cellulose in overlaid lamination is formed thereon. Finally, coagulate and regenerate the fibrous composite of the bio-polyamide 6,10 and natural cellulose by means of ejecting mist aerosol of water, and convert it into nonwoven fabric with hygroscopic metastatic feature by orderly applying post treatments of hydro-entangled needle punching, drying, winding-up processes.

According to an aspect of the present invention, there is provided a method for producing a nonwoven fabric, the method comprising the steps of providing fibres comprising 10-100 wt-% of bast fibres, the bast fibres having at least one angle of at least 20, and the bast fibres having an average fibre length of 10-60 mm; carding the fibres and forming a web of fibres on a wire support; hydroentangling the formed web by using at least a first and a second hydroentangling unit, wherein a hydroentanglement energy in the first hydroentangling unit is lower than the hydroentanglement energy in the second hydroentangling unit; dewatering the hydroentangled web; and drying the dewatered web at a temperature of 105-125 C.

A biodegradable wipe having a three-dimensional perforated structure pattern including a randomized web of pulp and spunlaced cellulosic fibres in a desired proportion, and optionally a colorant. The wipe in the present invention shows dual nature subject to wet or dry condition of the wipe and effectively traps and removes oily and sticky liquids without scratching underlying surfaces or irritating skin.
