The present invention provides a fabricating method for spunbond nonwoven from natural cellulose fiber blended with nano silver, which comprises following steps. Firstly, prepare nano silver colloidal sol by reduction titration for mixture of polyvinyl alcohol (PVA), silver nitrate (AgNO.sub.3) and sodium borohydride (NaBH.sub.4). Secondly, prepare mixing cellulose serum by blending agitation for mixture of wood pulp, N-methylmorpholine N-oxide (NMMO) and stabilizer. Thirdly, prepare blending mucilage from mixing cellulose serum via blending process. Fourthly, produce spinning dope by blending and dehydrating the nano silver colloidal sol and mixing cellulose serum. Fifthly, produce molten filament tow by spunbond spinning method in association with coagulation, regeneration, water rinse and high-speed stretching process. Finally, by post treatments of hydro-entangled needle punching, drying, winding-up processes in proper order, obtain final product of spunbond nonwoven from natural cellulose fiber blended with nano silver, which is biodegradable with features of antibacterial and antistatic capabilities.

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 non-Owoven covered roller comprising a resin-saturated seamless non-woven tube on a shaft and a process for making the non-woven covered roller comprising non-woven fibers and a shaft surface completely covered with at least the same resin wherein the resin-saturated non-woven tube has a hardness of at least 40 wet Shore A. It also has an outer surface configured to both trap metal debris from a metal web during primary metal fabrication operations and temporarily compress to allow larger metal debris associated with the metal web to pass by without permanently damaging the outer surface of the non-woven covered roller. Furthermore, it has an inner surface sufficiently bonded with the same resin to the outer surface of the shaft to permit satisfactory life of the resin-saturated non-woven covered roller during primary metal fabrication conditions similar to that of conventional shafts that are covered with rubber, urethane, or vinyl, and have not been exposed to the metal debris

In various embodiments, the present disclosure relates generally to a method for needling a spiral textile to create a needled preform, the method comprising receiving the spiral textile on a bed plate of a circular needle loom, engaging a positional structure of the spiral textile, rotating the spiral textile around the circular needle loom, depositing a predetermined number of layers of the spiral textile on the bed plate, and needling the spiral textile to create the needled preform. Moreover, the present disclosure also provides, in various embodiments, a method for creating a circular needled preform from a spiral textile, comprising attaching sacrificial fibers to at least one of the weft tow and the plurality of warp tows proximate at least one of the inside diameter and the outside diameter, and engaging the sacrificial fibers with an engagement mechanism on a circular needle loom.

A composite panel with a thermosetting cellular matrix, a method for manufacturing said panel, and a structure for covering a wall that is formed from an assembly of such panels. The structure provides the wall with heat insulation against cryogenic fluids and/or protection against fire or flames and/or sealing against the fluids. A panel having a thermosetting cellular matrix, includes at least one substrate that includes short, non-woven basalt fibers and is impregnated by the matrix. The panel is such that the at least one substrate includes a plurality of non-woven layers stacked to a stacking thickness. The non-woven layers each include the short basalt fibers and are needled through the thickness without using thermoplastic fibers.

A circular needle loom comprises a bed plate for receiving a transport layer. Engagement members may be disposed proximate to the bed plate, such that the engagement members interface with a positional structure of the transport layer that is used to position and rotate the transport layer around the bed plate. The engagement members may be configured to rotate the transport layer around the bed plate until a predetermined number of fibers and/or layers are deposited on the transport layer and/or bed plate in order to create a needled preform.
