    摘要： A method to manufacture an elastic laminate is disclosed. Thermoplastic Elastomeric Material (TEM) is selected from a polymer supply and fed into an extruder. The TEM film is extruded by the extruder by passing the TEM polymer through an extrusion die head to form a TEM film layer on a carrier web provided by a carrier supply. The TEM film layer is allowed to solidify on the carrier web, thereby forming a first laminate. The first laminate is stored in a first storage prior to being delivered to a delamination unit, which delaminates the first laminate by separating the TEM layer from the carrier web. The delaminated TEM layer is stretched at least in its Machine Direction (MD) in a stretching station via a plurality of web guide means. The stretched TEM layer is positioned between a first envelope web and optionally a second envelope web prior to being delivered to a bonding unit, which connects them to form a second bonded laminate. The second bonded laminate is unstretched and stored in a second storage for a predetermined time. The stored second bonded laminate is wound under controlled tension to form a roll or spool, thereby forming the elastic laminate.

    摘要： A nonwoven fabric is provided having a plurality of semi-crystalline filaments that are thermally bonded to each other and are formed of the same polymer and exhibit substantially the same melting temperature. The fabric is produced by melt spinning an amorphous crystallizable polymer to form two components having different levels of crystallinity. During spinning, a first component of the polymer is exposed to conditions that result in stress-induced crystallization such that the first polymer component is in a semi-crystalline state and serves as the matrix or strength component of the fabric. The second polymer component is not subjected to stress induced crystallization and thus remains in a substantially amorphous state which bonds well at relatively low temperatures. In a bonding step, the fabric is heated to soften and fuse the binder component. Under these conditions, the binder component undergoes thermal crystallization so that in the final product, both polymer components are semi-crystalline.

    摘要翻译： 提供了一种非织造织物，其具有多个彼此热粘合并由相同聚合物形成且呈现基本上相同的熔融温度的半结晶长丝。 织物通过将无定形结晶聚合物熔融纺丝以形成具有不同结晶度的两种组分来制备。 在纺丝期间，聚合物的第一组分暴露于导致应力诱导结晶的条件，使得第一聚合物组分处于半结晶状态并用作织物的基质或强度组分。 第二聚合物组分不经受应力诱导结晶，因此保持在相当低的温度下良好结合的基本无定形状态。 在粘合步骤中，织物被加热以软化并熔合粘合剂组分。 在这些条件下，粘合剂组分经历热结晶，使得在最终产品中，两种聚合物组分都是半结晶的。
