The problem of the present invention is to offer a nonwoven fabric for reinforcing foam molded articles that enables cushion materials to be efficiently foam molded by improving adhesiveness of the reinforcing nonwoven fabric to a mold. The present invention is a nonwoven fabric for reinforcing foam molded articles, having a reinforcing nonwoven layer and at least one resin layer, wherein the reinforcing nonwoven layer and the at least one resin layer are laminated, the reinforcing nonwoven layer has a discontinuous part including a magnetic material, the at least one resin layer has a resin having softening point A of 20&#xb0; C. or higher and 60&#xb0; C. or lower, and the nonwoven fabric has an air permeability of 30 cc/cm/sec or more and 300 cc/cm/sec or less.

Nonwoven fabric for reinforcing foam molded articles

The present invention relates to a backing having a three-layer structure prepared by sticking together an inner fiber layer for holding a pasty preparation, a film layer having through-holes, and an air-permeable outer fiber layer which prevents leaking out of the pasty preparation or a liquid component exuded from the pasty preparation, and also relates to an aqueous patch using the backing which can be applied for a long time.

Backing having three-layer structure and aqueous patch using the backing

It is provided that a nonwoven fabric for reinforcing foam molded articles which is excellent in the dimensional stability in a cutting/sewing step, in the followability to a mold in a foam molding step, and gives a foam molded article with excellent appearance and durability. A nonwoven fabric for reinforcing foam molded articles formed by interlacing at least 2 filament nonwoven fabric layers with different apparent density, wherein the nonwoven fabric has base weight of 50-110 g/m, thickness of 0.5-1.2 mm, 23 to 50 N/5 cm stress at the time of 5% elongation in longitudinal direction, 15 N/5 cm or lower stress at the time of 5% elongation in transverse direction, and air permeability of 50 to 250 cm/cm&#xb7;sec.

Nonwoven fabric for reinforcing foam molded articles and product using same

Provided is a thermocompression-bonding filament nonwoven fabric, which is inexpensive, has excellent molding properties and design properties, and is suitable as surface materials for automotive acoustic absorbing materials. The thermocompression-bonding filament nonwoven fabric comprising a polyester-based resin having a melting point of 250&#xb0; C. or more, wherein the filament nonwoven fabric has a weight of 20 to 80 g/m, a sum of 5% tensile loads in a MD and CD per weight of 1.0 to 1.9 (N/5 cm)/(g/m), and a 180&#xb0; C. dry heat shrinkage of 3.5% or less in both the MD and CD, and is not mechanically interlaced.

Thermocompression-bonding filament nonwoven fabric having excellent molding properties

The present invention relates to a backing for a water-based patch consisting of the following constituents, wherein the backing is excellent in pasty preparation retention and moisture retention, improves the persistence of drug efficacy by inhibiting the sublimation of the drug, gives neither restrained feeling nor rough feeling due to a thin thickness and an excellent elasticity, controls the moisture permeability, gives almost no sticky feeling and thereby gives an excellent feeling in application. A patch backing for a water-based pasty preparation consisting of a laminate, wherein the laminate consists of three layers, a film layer having through-holes is laminated between a nonwoven fabric layer A and a nonwoven fabric layer B, said film layer consists of a resin containing an olefin elastomer, the through-hole area per a hole is 0.02-0.18 mm, and the opening ratio of the through-hole is 1-10%.
