Webs can be embossed and laminated using irregular bonding patterns with the pin-on-pin embossing process. Different patterns are provided onto each web and the webs are joined in a bonding nip to form a laminate. The bonding pattern formed in the bonding nip is irregular. The irregularity of the bonding pattern reduces vibrations within the machinery and allows increased machine speed. The irregularity of the pattern can be determined using the Self-Similarity Count or the Energy Suppression Factor method.

An inexpensive breathable protective outer garment is produced from a breathable laminated fabric having a breathable film adhesively bonded to a nonwoven fabric. The film constitutes the outer layer of the garment and the nonwoven layer is on the inside. The seams of the garment are ultrasonically bonded such that the film sides of the laminate are in contact with each other during seaming.

The present invention pertains to an airlaid composite which is made of pulp fibers, at least about 2% by weight bicomponent fiber, and moisture. This airlaid composite is unique in that a uniformly even composite is made which upon calendering, becomes a thin structure which maintains significant absorbency when saturated. The bicomponent fibers of the present invention include a first polymer component and a second polymer component, and the first polymer component melts at a temperature lower than the melting temperature of the second polymer component. Mixing of the pulp fibers with the bicomponent fibers is done in such a way that the fibers are evenly dispersed in the airlaid composite. This airlaid composite is then heated such that at least a portion of the first polymer component of the bicomponent fiber is melted, which bond the bicomponent fibers to many of the pulp and bicomponent fibers when cooled. Moisture is added on to the composite to further facilitate bonding when the composite is subsequently subjected to calendering. Optionally, a sheet layer may be attached to the airlaid composite to form a multi-layered absorbent structure. Such composites and absorbent structures are characterized by a drape stiffness of at least about 5 cm, an absorbency of at least about 12 g/g, and a dry tensile strength of at least about 1300.

A method for making an absorbent member is disclosed. The method includes introducing fibers into an air stream to form an air-fiber mixture. This air-fiber mixture is then directed to a porous media having a first surface. The air-fiber mixture contacts the first surface and the fibers collect on the first surface and forms a fibrous mat. The air passes through the first surface and can be recovered and recycled, if desired. The air-fiber mixture is then terminated or diverted so that the fibrous mat can be removed from the first surface. The fibrous mat is wetted by water to obtain a desired moisture content. Finally, the wetted fibrous mat is compressed to a predetermined thickness to form an absorbent member, which has unique expansion properties.
摘要:
An absorbent member is disclosed which has a high absorbent capacity and which exhibits exceptional expansion properties when wetted by an aqueous fluid. The absorbent member includes a multitude of randomly oriented cellulosic fibers having an average length of from between about 1 mm to about 5 mm and containing at least about 20% lignin within each fiber. The absorbent member also has a moisture content of from between about 1% to about 20% water by weight of fiber and has a density in the range of from between about 0.1 g/cc to about 1 g/cc. The fibers are stressed and bonded by hydrogen bonds and are retained in an elastically stressed condition.

Generating a visual three-dimensional model specific to a user for personal care education. A request for instruction regarding a personal care product is received from a user. Data defining physical characteristics of the user that relate to the personal care product is also received from the user. A three-dimensional model demonstrating use of the personal care product is generated. The three-dimensional model is a function of the received data and the personal care product. The generated three-dimensional model is provided to the user for display.
