摘要： The present disclosure relates to methods for assembling elastomeric laminates, wherein elastic material may be stretched and joined with either or both first and second substrates. First spools are rotated to unwind first elastic strands from a first unwinder in a machine direction. The first elastic strands are positioned between the first substrate and the second substrate to form an elastomeric laminate. Before the first elastic strands are completely unwound from the rotating first spools, second spools are rotated to unwind second elastic strands from a second unwinder. Subsequently, the advancement of the first elastic strands from the first unwinder is discontinued. Thus, the elastomeric laminate assembly process may continue uninterrupted while switching from an initially utilized elastic material drawn from the first spools to a subsequently utilized elastic material drawn from the second spools.

摘要： A method of preparing a nanocomposite fiber comprising suspending carbon powder comprising graphene flakes in a carrier fluid. A solid polymer material is added to the carrier fluid having the carbon powder suspended therein to create a mixture. The mixture is heated and the solid polymer material is at least partially dissolved within the carrier fluid having the carbon powder suspended therein. The carrier fluid is removed from the mixture, forming the polymer into a fiber carrying the graphene flakes.

摘要： A hollow fiber that extending along at least a portion of the fiber along a longitudinal axis thereof and is defined by an interior wall is provided. Through selective control over the manner in which it is formed, the present inventors have discovered that the hollow fiber can exhibit a unique combination of a high void fraction and small fiber size that makes it particularly suitable for use in certain applications, such as in nonwoven webs for absorbent articles.

摘要： The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. The elastomeric laminates may include a first substrate, a second substrate, and an elastic material located between the first and second substrates. During assembly of an elastomeric laminate, a beam is rotated to unwind the elastic strands from the beam, wherein the strands may include a spin finish. First bonds are applied to bond discrete lengths of the stretched elastic strands with and between the first substrate and the second substrate, wherein the discrete first bonds are arranged intermittently along the machine direction. In addition, second bonds are applied between consecutive first bonds to bond the first and second substrates directly to each other, wherein the second bonds extend in the machine direction and may be separated from each other in a cross direction by at least one elastic strand.

摘要： An absorbent article having longitudinal cuffs of improved structure is disclosed. The improved cuffs may be elasticized by a plurality of elastic strands that are substantially greater in number, closer in spacing, lower in pre-strain, and lower in decitex, or any combination of these, as compared with those in conventional articles. This combination of features results in ruffles or gathers of cuff material joined to the elastic strands that are substantially greater in machine-direction frequency and substantially lesser in z-direction amplitude, than those in conventional articles. As a result, the cuff structure lies more closely and evenly against the wearer's skin, has an improved, more cloth-like appearance, provides improved gasketing, and provides improved wearer comfort, as compared with cuff structures in conventional articles. A method for manufacturing articles with such cuff structures, utilizing a warp beam as a supply mechanism, is also disclosed.
