Abstract: An improved nonwoven web composite is formed by combining splittable bicomponent thermoplastic filaments with a component selected from other fibers and particles. The bicomponent filaments include distinct regions of first and second incompatible polymers extending the length of the filaments. After the bicomponent filaments are combined with the other fibers and/or particles, the bicomponent filaments are caused to split lengthwise along boundaries between the regions of different polymers, resulting in a web or matrix of finer filaments which entrap, ensnare and contain the other fibers and/or particles within the web or matrix. The nonwoven web composite is particularly useful for making absorbent articles, which require durability and optimum levels of absorbent fibers and/or particles.

Abstract: The present invention is directed to crimped and resilient polymeric fibers and to fabrics and laminates made from the fibers. In general, the fibers are produced by crimping a polymeric fiber and then cross-linking a polymer and/or monomer contained within the fiber. Cross-linking the polymer makes the crimp contained with the fiber more permanent and more resilient. When formed into a nonwoven web, the fibers produce high loft fabrics which are resilient to compressive forces. Nonwoven webs made in accordance with the present invention are particularly well suited for use in filter products and liquid absorbent products.

Abstract: A nonwoven papermaker’s fabric, usable in the dryer section of a paper machine, has a spiral wound machine direction (MD) base layer of raw stock which is wound around a pair of parallel rolls or cylinders until the desired length and width is achieved. The spiral wound MD layer is overlaid with a cross-machine direction (CD) layer of similar or dissimilar raw stock and mated by any of a number of means. The spiral wound MD layer can also be mated to another MD layer spiraled in the opposite direction and in one embodiment further mated to a CD layer. The fabric is preferably produced so that its neutral line is oriented toward the paper side of the fabric so that the paper sheet will stretch less than when typical dryer fabrics are used to turn the paper sheet and fabric around the dryer cylinders.

Abstract: A bonded web of multi-component strands that include a first polymeric component and a second polymeric component is capable of overcoming a number of problems associated with nonwoven webs including both stickiness and blocking. The first polymeric component and second polymeric component are arranged in substantially distinct zones extending longitudinally along at least a portion of a length of the strands which make up the web with the second component containing a zone constituting at least a portion of the peripheral surface of the strand. The first polymeric component also has an elasticity which is greater than that of the second polymer component. A process producing elastomeric spunbonded nonwoven fabrics which utilizes the activation by incremental stretching of the strands is also provided.

Abstract: This invention relates to a method for preparing nonwoven fabrics having an improved balance of properties in the machine and cross-directions. More specifically, the invention utilizes nonwoven webs that include relatively low levels of multiple-component fibers having latent three-dimensional spiral crimp combined with fibers that do not develop spiral crimp. The latent spiral crimp of the multiple-component fibers is activated, such as by heating, under free shrinkage conditions, after formation of the nonwoven web to achieve re-orientation of the non-spirally-crimpable fibers and an improved balance of properties such as tensile strength and modulus.
