摘要:
The present invention relates to a web of vegetable wool fibres of which the mechanical cohesion is ensured by a fully or partially biosourced thermoplastic polymer. In particular, said polymer consists of poly(hydroxyurethane) (5), and is sourced, at least partially, from biomass. The poly(hydroxyurethane) (5) is preferably obtained through a reaction between two comonomers, the first comonomer corresponding to a dicyclocarbonate unit (3) and the second comonomer consisting of a diamine unit (4).

Provided are: a homogeneous fiber board which has small variation in weight per square meter; and a method of the same. The present fiber board (100) is obtained by: mixing a vegetable fiber (1) (such as kenaf fiber) and a thermoplastic resin fiber (such as polypropylene fiber) to form a web; forming a fiber mat by needle punch method or the like to interlace the fibers that constitute the web; and heating and compressing the fiber mat. The vegetable fiber is crimped in advance by stirring a raw material fiber in presence of water. The present production method has: a web-forming process wherein a web is formed by mixing a vegetable fiber and a thermoplastic resin fiber; a mat-forming process wherein a fiber mat is formed by interlacing the fibers that constitute the web; and a board-forming process wherein a fiber board is formed by compressing the fiber mat with heating.

The present invention relates to an absorbent fibrous product containing at least 50% of cotton fibers or other cellulose fibers and less than 0.1% of a chemical or hot-melt binder, including a first layer consisting of hydroentangled non-woven fabric and a second layer consisting of fibers that are more weakly bonded together than the fibers of the first layer, the bonding of the fibers of the second layer resulting from a hydrophilic treatment of the layer of fibers, the two layers being bonded by adhesion of the entire surface between the fibers of the two layers, and the debonding force being at least 0.1 N. The invention also relates to a manufacturing method, which includes the following steps: a) forming at least two separate laps of fibers, one of which is at least partially made of cotton fibers or other cellulose fibers; b) consolidating a first of said laps by bonding using fine water jets; c) stacking the laps; and d) the hydrophilic treatment of the formed complex lap by means of wetting, followed by extracting the liquid, in particular by subjecting the lap to negative pressure.

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.

Cellulosic fibers having enhanced reversible thermal properties and applications of such cellulosic fibers are described. In one embodiment, a cellulosic fiber includes a fiber body including a cellulosic material and a set of microcapsules dispersed in the cellulosic material. The set of microcapsules contain a phase change material having a latent heat of at least 40 J/g and a transition temperature in the range of 0°C to 100°C, and the phase change material provides thermal regulation based on at least one of absorption and release of the latent heat at the transition temperature. The cellulosic fiber can be formed via a solution spinning process, and can be used in various products where thermal regulating properties are desired.
