Absorbent article with three-dimensional hot-melt bonded laminate
An absorbent article such as a baby diaper comprising a three-dimensional laminate 30 having a first layer 1 intermittently bonded to a second layer 2 by a heterophase polymer. The topsheet comprises three-dimensional protrusions 9 in the first layer 1 which are not bonded to the second layer 2. The heterophase polymer has an enthalpy of fusion of at least 10 J/g. The laminate may be used on the wearer-facing side of the article as topsheet 24 and/or on the garment-facing side as part of the backsheet 26. The first layer may comprise natural fibers.
NONWOVEN JOINT TAPE HAVING LOW MOISTURE EXPANSION PROPERTIES AND METHOD FOR USING SAME
The invention is directed to a joint tape for finishing a joint between boards comprising a nonwoven substrate that does not swell substantially in the presence of water. The invention further provides a method of finishing a joint between boards comprising (i) applying a joint tape of the invention to a joint between boards by embedding the joint tape in a first coat of joint compound, (ii) applying a second coat of joint compound over the tape, wherein step (ii) is carried out before the joint tape and joint compound applied in step (i) have substantially dried, and optionally (iii) applying a third fill or finish coat of joint compound over the tape, wherein step (iii) is carried out before the joint tape and second coat have substantially dried.
MOUNTING MAT FOR A POLLUTION CONTROL DEVICE
The present invention provides a mounting mat for mounting a pollution control element or monolith in a pollution control device, said mounting mat comprising a layer having a mixture of long and short fibers wherein said short fibers have a length of not more than about 13 mm and wherein said long fibers have a length of at least about 20 mm and wherein the amount of said short fibers is at least about 3% by weight based on the total weight of said mixture of long and short fibers.

TIME-DEPENDENT SYNTHETIC BIOLOGICAL BARRIER MATERIAL
Thermally stable absorbable fiber populations, i.e. fiber populations that do not undergo thermally induced crystallization, can be intermixed to yield a stabilizing effect without altering morphological properties of a first fiber system. By addition of a stabilizing fiber population one may minimize thermally induced shrinkage and maintain physical properties of electrospun materials in the as-formed state. In one particular abstract, medical barrier materials may be formed from the electrospun materials to provide improved medical barriers for treatments.
SOUND ABSORBER AND WIRING HARNESS WITH SOUND ABSORBER
If a thickness of a sound absorber arranged in a vehicle and clearances in the vehicle do not match and gaps are formed between the sound absorber and the respective members in the vehicle, abnormal noise due to the mutual contact of the members and noise outside the vehicle enter the vehicle interior to impair vehicle interior quietness. This is solved by a sound absorber which includes a nonwoven fabric containing 5 to 50 mass % of second fibers having a lower melting point than that of first fibers and can cause the first and second fibers to be more loosely interfaced and increase a volume of the nonwoven fabric by heating the nonwoven fabric to about the melting point of the second fibers and softening or melting the second fibers even after production.
SOFT ABSORBENT COFORM NONWOVEN WEB
Soft and strong nonwoven web materials and methods of formation are described. In one embodiment, a nonwoven web material may comprise meltblown polymer fibers comprising bicomponent fibers formed of a first polymer component and a second polymer component, and monocomponent fibers formed only of the first polymer component, or a third polymer component that is different than either of the first polymer component and the second polymer component, and absorbent fibers, wherein the nonwoven web material has a TS7 Softness value of less than or equal to 3.9, according to the TS7 Softness Test Method.
