Thermoplastic non-woven textile elements
A non-woven textile may be formed from a plurality of thermoplastic polymer filaments. The non-woven textile may have a first region and a second region, with the filaments of the first region being fused to a greater degree than the filaments of the second region. A variety of products, including apparel (e.g., shirts, pants, footwear), may incorporate the non-woven textile. In some of these products, the non-woven textile may be joined with another textile element to form a seam. More particularly, an edge area of the non-woven textile may be heatbonded with an edge area of the other textile element at the seam. In other products, the non-woven textile may be joined with another component, whether a textile or a non-textile.

THERMALLY INSULATING SHEET FORMED FROM A DOWN CORE STRUCTURE AND METHOD OF FABRICATION
A thermally insulating sheet formed by a down core structure which is comprised solely of down feather material mixed with binding material which is heat fused together to form a homogeneous sheet core. The method of fabricating the homogeneous thermally insulating sheet to form the down core structure is described. This novel method restrains the down clusters and binding material during the process of mixing, depositing, conveying and heat fusing to form a homogeneous down core sheet. The down core structure is subjected to two separate heat treatments which produces a down core sheet having at least some of its outer surfaces being of higher bond density than the inside of the core.
Making a nonwoven from fibers
The invention relates to a method for producing a nonwoven fabric from fibres, wherein the fibres are spun by means of at least one spinneret, are cooled and then deposited on a collection device to form a nonwoven web. The nonwoven web undergoes hot fluid bonding during at least two consecutive bonding steps. In a first bonding step, the surface of the nonwoven web is subjected to a hot fluid and, in a second bonding step, the surface of the nonwoven web is also subsequently subjected to a hot fluid and, in addition and at the same time, surface pressure is exerted on the nonwoven web.

Nonwoven molded article
A nonwoven molded article may include at least one thermoformed nonwoven fabric. The fabric may include structural fibers having polyethylene terephthalate, first bicomponent binder fibers, optional second binder fibers, and optional additives. The first bicomponent binder fibers may include matrix-forming polyethylene-terephthalate having a semicrystalline sheathing material having a melting point ranging from 90 to 175° C. The optional second bicomponent binder fibers may include matrix-forming polyethylene-terephthalate having a semicrystalline sheathing material and differ from the first bicomponent binder fibers.
Base material nonwoven fabric for molding and molded product obtained by the same
An object is to realize a base material nonwoven fabric for molding excellent in handling as a material, by preventing peeling between laminated components constituting the base material for molding; and even after the base material is reheated and molded, to provide a molded product having excellent elasticity resistant to external forces such as flying debris or the like, and while maintaining peeling resistance, capable of realizing excellent sound absorbing characteristics, by suppressing air permeability inhibition due to the adhesive component. A base material nonwoven fabric for molding in a predetermined shape by heat molding, characterized by having a two-layer structure of a long fiber nonwoven fabric layer comprising at least a polyester resin and a short fiber nonwoven fabric layer comprising a polyester resin, wherein a flow-solidified undrawn polypropylene layer is localized in the vicinity of an interface between the long fiber nonwoven fabric layer and the short fiber nonwoven fabric layer.
