Filed:

Oct 19, 2004

Appl. No.:

10/904002

Inventors:

Hassan Bodaghi - Alpharetta GA, US
Mehmet Sinangil - Duluth GA, US

Assignee:

Aktiengesellschaft Adolph Saurer - Arbon

International Classification:

B27N 3/04

US Classification:

264115, 156167

Abstract:

Apparatus and method for forming nanofibers and nonwoven webs formed of such nanofibers. The nanofibers are formed by changing the rheology in at least first and second flows of a liquid material such that the changed rheology of the first and second flows differs by an amount sufficient to produce a phase separation when the first and second flows are combined to define meltblown fibers. Each meltblown fiber has lengthwise first and second cross-sectional regions formed of the liquid material from the first and second flows, respectively. These regions are separated along a length of at least a majority of the meltblown fibers to form a plurality of nanofibers, which are collected together with any unsplit meltblown fibers to form the nonwoven web. The difference in the changed rheology of the flows may be produced by using two extruders with different barrel diameters to create differ shear histories for the two flows.

US Classification:

239/290000

Abstract:

Apparatus and methods for applying adhesive to one or more narrow substrates, such as elastic strands, that are in motion. The apparatus includes a coating applicator and an air moving device mounted adjacent to the coating applicator. The coating applicator is capable of applying adhesive in the form of an adhesive filament in a pattern onto each narrow substrate. The air moving device includes one or more air discharge passages capable of directing a flow of air toward the narrow substrate. The flow of air transfers momentum to airborne sections of the adhesive filament for promoting coating uniformity on the narrow substrate.

D04H 1/4291
D04H 1/56

Abstract:

Nonwoven fabrics are provided that include a plurality of mono-component spunbond fibers comprising a polymeric material including a polymeric blend of (i) a TS7 value of at most about 30 as determined by a Tissue Softness Analyzer (TSA) from Emtec Innovative Testing Solutions; (ii) a HF value of at least about 40 as determined by a Tissue Softness Analyzer (TSA) from Emtec Innovative Testing Solutions; (iii) a delta value of at least 20, wherein the delta value is determined by subtracting the TS7 value from the HF value; (iv) a TS7 value that is from about 5% to about 35% lower than that of an identically constructed nonwoven fabric formed from 100% polypropylene; and (v) a HF value that is from about 5% to about 35% larger than that of an identically constructed nonwoven fabric formed from 100% polypropylene.

Abstract:

Nonwoven fabrics having liquid barrier properties are provided. The nonwoven fabrics may include one or more nonwoven layers, in which one or more of the nonwoven layers may include a liquid-barrier-enhancing-additive (LBEA) comprising an amide. The nonwoven fabrics may be suitable for use in a wide variety of liquid barrier applications, including facemasks, surgical gowns, surgical drapes, lab coats, and barrier components of absorbent articles (e.g., barrier leg cuffs).
