Embodiment Construction

[0018] The present invention is concerned with multicomponent filaments and their incorporation into various components of sanitary articles. refer to image 3 Generally, the disposable hygiene article 10 comprises a topsheet 12, a backsheet 14 and a fluid storage layer 16 between the topsheet 12 and the backsheet 4. The topsheet 12 transfers aqueous body fluids, such as urine, into the fluid storage layer 16 . The hygiene article 10 includes a fluid acquisition and transfer layer 15 between the fluid storage layer 16 and the topsheet 12, which enables the fluid capacity of the base fluid storage layer 16 to be fully utilized. The fluid acquisition and transfer layer 15 is positioned between the topsheet 12 and the fluid storage layer 16 in the hygiene article. The fluid acquisition and transfer layer 15 distributes aqueous body fluids transferred from the topsheet 12 in the x-y dimension. The term "X-Y dimensional direction" as used herein means a plane normal to the Z dim...

Abstract

A method of forming a plurality of substantially-continuous and uninterrupted multi-component filaments for use as a high-loft non-woven web. The multi-component filaments include at least two polymers of different melt flow rates, which imparts latent crimp in each filament. After collection, the latent crimp of the filaments is activated either thermally or by applying tension to the non-woven web.

Description

technical field [0001] This invention relates generally to melt spinning processes and products, and more particularly to processes and high loft nonwoven webs formed from multicomponent filaments. Background technique [0002] Melt spinning technology is often applied to the manufacture of nonwoven webs and multi-layer laminates or composites, which are made into various consumer and industrial products, such as single-use components or short-life hygiene products, disposable protective clothing, Fluid filtration media, and durable goods, including bedding and carpet coverings. Melt spinning techniques include spunbonding and meltblowing, which form nonwoven webs and composites from one or more layers of entangled filaments or fibers made of one or more Thermoplastic polymer composition. [0003] Certain nonwoven webs and composites are formed by known melt spinning processes, such as spunbonding, which include melt spinning of thermoplastic polymers. The spunbond proces...
