A compression bandage that is formed by the assembling of a self-adhesive nonwoven based on short conjugate fibers which have been crimped and of an elastic material, the effectiveness of which increases over time. The bandage can be used, alone or in a bilayer compression system, for the prevention or treatment of venous pathologies or lymphedema.

A compression bandage formed by the assembling of a nonwoven based on short conjugate fibers which have been crimped and of a nonelastic material. The compression bandage can be used in a bilayer compression system, in particular for the prevention or treatment of venous pathologies.

There is provided a laminated nonwoven fabric having excellent sound absorbing performance in a low frequency range, the laminated nonwoven fabric having a skin layer and a base material layer, the skin layer having a nonwoven fabric A, the nonwoven fabric A having a density of 100 to 500 kg/m.sup.3, a thickness of 0.5 to 2.5 mm, and an air permeability of 4 to 40 cm.sup.3/cm.sup.2/s; and the base material layer having a nonwoven fabric B, the nonwoven fabric B having a basis weight of 200 to 500 g/m.sup.2 and a thickness of 5 to 40 mm.

A depth filter with excellent filtration accuracy and pressure resistance performance even for fluids containing high density and high viscosity powder fine particles. A depth filter having a base material layer, a filtration layer, and a skin layer, in that order, wherein: the substrate layer and the skin layer are layers made by a nonwoven fabric being wound and thermally fused; the filtration layer is a laminate in which at least a nonwoven fabric and a net are laminated, being wound twice or more; and the nonwoven fabric contained in the filtration layer contains a mixed-fiber nonwoven fabric containing two or more types of fibers with mutually different average fiber diameters.

Tough, durable nonwoven composite fabric panel product and two precursors thereof.

The present invention concerns a process for the preparation of a flocked material for coating surfaces and structures such as the interiors of automobiles, objects for interior decorating (walls, sofas, armchairs, etc.), handbags, suitcases or other accessories, covers or cases for weapons, musical instruments or electronic devices, or to make carpets and/or rugs, and that comprises the use of bicomponent fibres of the island-in-the-sea type of limited length (microfibres). The process of the invention comprises a step of partial and selective dissolution of the sea component by an alkaline removal agent, which makes it possible to obtain a flocked material characterized by improved resistance to abrasion and a more appealing appearance compared to flocked products of the prior art.

The present invention refers to a nonwoven web with multicomponent fibers having at least a first and a second component which differ from each other in color. The nonwoven web is pattern bonded to obtain bonded areas have a different color versus the unbonded areas.

Dimensionally stable nonwoven fibrous webs include a plurality of fibers formed from one or more thermoplastic polyesters and an antishrink additive, preferably in an amount greater than 0% and no more than 10% by weight of the web. The webs have at least one dimension which decreases by no greater than 12% in the plane of the web when heated to a temperature above a glass transition temperature of the fibers. The webs may be used as wipes.

A multi-component fiber including at least first and second components. In some cases, at least a portion of the first component is opaque and microporous, and the second component is different from the first component. In some cases, at least a portion of the second component can be seen through at least a portion of the first component. A fiber having an opaque, microporous region and a see-through region of lower porosity is also disclosed. Fibrous webs including such fibers are also disclosed. In some cases, the fibrous web has at least one first region where first portions of the multiple fibers are opaque and microporous and at least one second region where second portions of the multiple fibers form a see-through region of lower porosity. Articles and laminates including the fibrous webs are disclosed. Methods of making the fibers, fibrous webs, and articles are also disclosed.

A sea-island composite fiber in which island components are interspersed in a sea component on a fiber cross-section, wherein the island components have a composite structure formed with two or more different polymers joined together, and the ratio (L/D) of the length (L) of the joint section of the island component and the diameter (D) of the composite island component is 0.1 to 10.0. The sea-island composite fiber has satisfactory high-order processability, and therefore can be produced with high productivity and quality using existing equipment, and thin fibers obtained by removing the sea component have functions of structure control while having an excellent tactile impression.
