VIBRATING DEVICE FOR AN INSTALLATION FOR PRODUCING A NONWOVEN, FABRIC WEB
A vibration device for an arrangement for producing a nonwoven fabric web, wherein the vibration device is configured to be arranged in a transverse direction of the arrangement under a conveyor belt for fibers from which the nonwoven fabric web is produced, wherein the vibration device is configured to cause the conveyor belt and the fibers transported thereon to vibrate, and wherein the vibration device includes a beam whose top side is configured to contact a bottom side of the conveyor belt at least temporarily, wherein the beam is supported or only excited or excitable by the vibration device so that the beam essentially performs or permits no vibrations in a conveying direction of the arrangement.

CUTTABLE KNITTED FABRIC AND METHOD FOR MANUFACTURING THE SAME
A cuttable knit fabric of the present invention may comprise: a knitted fabric woven with a single yarn; a first reinforcing part disposed to correspond to a central portion on the lower surface of the knitted fabric; and a second reinforcing part disposed to surround the periphery of the first reinforcing part on the lower surface of the knitted fabric. A first reinforcing fiber of the first reinforcing part and a first reinforcing fiber of the second reinforcing part may be formed by tangling with the yam of the knitted fabric. The first reinforcing part and the second reinforcing part may be formed of different materials. The first reinforcing part and the second reinforcing part may have different tensile strengths.

Multipurpose functional nonwoven fiber, and method for manufacturing same
The present invention relates to a multipurpose functional nonwoven fabric, and more particularly, to a multipurpose functional nonwoven fabric which is manufactured by performing a pretreatment process on carbonized fiber cotton, and stacking the pretreated carbonized fiber on natural cotton, mixing the pretreated carbonized fiber cotton with the natural cotton and scutching the mixed cotton, or introducing the natural cotton and stacking the natural cotton on an intermediate layer of the pretreated carbonized fiber, and a method for manufacturing same. Web formation and stacking at a cutting machine can be easily performed by performing the pretreatment process on the carbonized fiber. Also, excellent heat resistance and conductivity can be obtained by stacking the carbonized fiber cotton on natural cotton, mixing the carbonized fiber cotton with the natural cotton, scutching the mixed carbonized fiber cotton and the natural cotton and stacking the scutched cotton, or introducing natural cotton into an intermediate layer of the carbonized fiber cotton, stacking the natural cotton on the intermediate layer of the carbonized fiber cotton, and subjecting the stacked cotton to needle punching. Since a surface temperature of the nonwoven fabric can be lowered and the loss of heat can be reduced through dissipation and dispersion of heat, thermal retention and insulation properties of the entangled natural cotton can be enhanced, and carbonization prevention and incombustiblization of the natural cotton can be achieved. Also, the multipurpose functional nonwoven fabric can be manufactured at a low production cost and exhibit environmentally friendly characteristics, and a waste material can be recycled.

REINFORCED NON-WOVEN FABRIC, ASSEMBLY INCLUDING SUCH A FABRIC, AND METHOD FOR TREATING A NON-WOVEN FABRIC
A non-woven sheet (10) comprises at least one zone of reinforcement (20a, 20b, 20c, 20d) in which fibers and/or filaments constituting the sheet are bonded together in a reinforcing pattern (22) comprising a plurality of geometric shapes (24), the zone of reinforcement extending over the entire length (L) of the sheet measured in the longitudinal direction (X1), and over a width (l1, l2) strictly less than the width (l) of the sheet (10) measured in a lateral direction (Y1) orthogonal to the longitudinal direction (X1). The sheet (10) thus further comprises at least one non-reinforced zone (30a, 30b). Because of the bonding between the fibers and/or filaments, the elongation of the reinforced zone (20a, 20b, 20c, 20d) under the effect of a given force exerted in a longitudinal direction of the sheet (10) is less than the elongation of the non-reinforced zone under the effect of the same force. Such a sheet (10) may be used in particular for fabricating a laminated assembly.
