The invention relates to an impregnated yarn, a ribbed thin-walled composite product comprising such an impregnated yarn, and a method of making them. Such an impregnated yarn (10d; 10e) comprises at least two continuous strands (10a; 10b) comprising plant fibers (11), said strands (10a; 10b) being impregnated with thermoplastic material (12a) in at least 60% of their volume, each of said strands (10a; 10b) being individually twisted and all of said strands (10a; 10b) also being twisted in a configuration (10d) held by the thermoplastic material (12a).

A thread conditioner dispenser is provided as well as a method of conditioning thread. The dispenser has a base with two longitudinally extending sidewalls attached which are joined by two transverse sidewalls. A receptacle for thread conditioning compound is defined interior thereto. Notches are formed in each transverse sidewall. The point on each notch closest to the base defines a saddle point. An adhesive layer is attached to the base such that the dispenser may be removably attached to a solid surface. Thread may be passed through one of the notches and withdrawn through the opposed notch.

A welding process may be configured to convert a substrate into a welded substrate by applying a process solvent to the substrate, wherein the process solvent interrupts one or more intermolecular force between one or more component in the substrate. The substrate may be configured as a natural fiber, such as cellulose, hemicelluloses, and silk. The process solvent may be configured as an ionic-liquid based solvent and the welded substrate may be a congealed network after the process solvent has been adequately swollen and/or mobilized the substrate. A welding process may be configured such that individual fibers of a substrate are not fully dissolved such that material in the fiber core may be left in the native state by controlling process variables. The welding process fibers may have a tenacity 10% or 20% greater or a diameter 25% less than that of a cellulosic-based yarn substrate.

The present invention is at least one coating machine (1) having at least one impregnation unit (2) for realizing dyeing during wrapping of the yarn (26) from at least one first bobbin (25) onto at least one second bobbin (41), at least one drying unit (3) for providing drying of the yarn (26) dyed essentially in the vicinity of said impregnation unit (2), at least one first roller (355) and at least one second roller (359) positioned mutually for providing moving of the yarn (26) at a predetermined line in said drying unit (3), at least one wrapping unit (4) for providing wrapping of the yarn (26), dyed in the vicinity of the drying unit (3), onto said second bobbin (41). The improvement of the present invention is that said second roller (359) is configured to displace between an operation position (I) defined at one side of said first roller (355) and a yarn changing position (II) defined at the other side of said first roller (355).
