A nonwoven web made of plastic fibers and having a web thickness less than 2 mm (preferably less than 1.5 mm) and a grammage less than 30 g/m.sup.2 (preferably less than 25 g/m.sup.2) and conveyed this web in a travel direction so that it physically contacts a guide or treatment roller. A stabilization plate extending in and transversely to the travel direction of the nonwoven web is provided upstream or downstream of the roller in the travel direction, and the nonwoven web is guided in the travel direction past the stabilization plate such that a spacing between a face of the stabilization plate turned toward the nonwoven web and the nonwoven web face is 0 to 20 mm (preferably 0.1 to 10 mm, and very preferably 0.2 to 5 mm).

It is intended to improve texture of a decoration using a stitch line while improving workability in sewing for forming the stitch line at a skin material, to promote manufacturing efficiency as compared to formation of a stepped shape only by sewing, and to reduce the number of steps. A skin material is used for a conveyance seat, and is molded using a die. The skin material includes a linearly-extending stepped portion having a stepped shape transferred from the die, and a stitch line sewn along the stepped portion. The stepped portion serves as a guide upon formation of the stitch line.

A method of fabricating a composite material part comprises fiber reinforcement densified by a matrix. The method comprises the following steps: making a fiber fabric by weaving yarns having an initial mean fiber percentage; and densifying the fiber fabric with a matrix. The fiber fabric is subjected, prior to densification, to one or more jets of water under pressure so as to reduce the mean fiber percentage in the fabric to a value lying in the range 20% to 45%.

According to an aspect of the present disclosure, an airfoil apparatus is provided which minimizes entry of entrained air into a system having a controlled internal environment, such as a corona treatment system, such entrained air resulting from a high-speed web moving into the system. According to another aspect of the present disclosure, the airfoil apparatus is rotatable relative to the system so that the airfoil apparatus can be adjusted to changes in the web.

A carpet product including a primary backing layer and a plurality of yarn tufts. The plurality of yarn tufts are tufted in and extend upwardly from a top surface of the primary backing layer to form a tufted carpet product. The carpet product has an inner portion and a peripheral portion surrounding at least a portion of the inner portion and extending along at least one of the edges of the primary backing layer. The plurality of yarn tufts include a plurality of peripheral yarn tufts positioned within the peripheral portion of the tufted carpet product. A portion of the peripheral yarn tufts are anchored to other peripheral yarn tufts. At least a portion of each anchored peripheral yarn tuft is entangled with one or more of the other peripheral yarn tufts.

A hydrophobic finishing apparatus of a fabric is described. The hydrophobic finishing apparatus includes a first spray coating device, at least one first plasma device, a second spray coating device and at least one second plasma device. The first spray coating device is configured to spray a hydrophobic agent to a first side of the fabric. The first plasma device is disposed at the rear of the first spray coating device and is configured to perform a first plasma treatment on the first side of the fabric. The second spray coating device is disposed at the rear of the first plasma device and is configured to spray the hydrophobic agent to a second side of the fabric. The second plasma device is disposed at the rear of the second spray coating device and is configured to perform a second plasma treatment on the second side of the fabric.
