A clinical garment for patient warming including a front body panel having a first edge, an opposite second edge, an insulated sheet comprising an insulated layer positioned between an outer layer a film layer, a permeable layer adjacent to the film layer of the insulated sheet, a blanket section defined by a lower portion of the insulated sheet sealed to a lower portion of the permeable along a top edge, a bottom edge, and opposite first and second side edges of the blanket section, and at least one inlet port extending into the blanket section. The garment further includes a first back panel secured to at least a portion of the first edge of the front body panel and a second back panel secured to at least a portion of the second edge of the front body panel.

Patient warming systems and corresponding methods

A pleated multilayer air filter assembly including a primary filtration layer and a prefilter layer that are bonded to each other and are co-pleated with each other. The primary filtration layer includes meltblown electret fibers. The prefilter layer includes meltspun, spunbonded electret fibers that comprise a radially outer surface comprising polymethylpentene. The ratio of Effective Fiber Diameter of the fibers of the primary filtration layer to Effective Fiber Diameter of the fibers of the primary filtration layer is at least 1.5.

Pleated filtration assembly comprising spunbonded prefilter

Provided are acoustic articles, and related methods, that include a porous layer and heterogeneous filler received in the porous layer. The heterogeneous filler can include clay, diatomaceous earth, graphite, glass bubbles, polymeric filler, non-layered silicate, plant-based filler, or a combination thereof, and can have a median particle size of from 1 micrometer to 1000 micrometers and a specific surface area of from 0.1 m/g to 800 m/g. The acoustic article can have an overall flow resistance of from 100 MKS Rayls to 8000 MKS Rayls. The acoustic articles can serve as acoustic absorbers, vibration dampers, and/or acoustic and thermal insulators.

Acoustic articles and methods thereof

The present disclosure relates to multi-layer composite articles including at least two nonwoven web layers. Each or the layers may be a spunbonded web, and each may include biodegradable materials. The multi-layered composites of the present disclosure are particularly well suited for air filtration, as they can combine a high dust holding capacity with sufficient strength, dimensional stability, and a relatively low pressure drop.

Multi-layer, biodegradable composites for air filtration

Provided are acoustic articles having a porous layer () placed in contact with a heterogeneous filler comprising porous carbon and having an average surface area of from 0.1 m/g to 10,000 m/g. The acoustic articles can have a flow resistance of from 10 MKS Rayls to 5000 MKS Rayls. Optionally, the porous layer includes a non-woven fibrous layer or a perforated film having a plurality of apertures with an average narrowest diameter of from 30 micrometers to 5000 micrometers. The heterogeneous filler can enhance low frequency performance without significantly compromising high frequency performance, thickness or weight.

Acoustic article and related methods

The provided articles, assemblies, and methods use a non-woven fibrous web () having one or more layers () that are densified in situ to provide a layer that is densified relative to one or more adjacent layers, collectively within a unitary non-woven construction. The non-woven web () can be made from fibers having a composition and/or structure that resist shrinkage induced by polymer crystallization when subjected to high temperatures. Advantageously, the provided non-woven webs () can be molded to form a three-dimensional shaped article that displays dimensional stability.

Non-woven fibrous web and methods thereof

A relofted, spunbonded nonwoven web exhibiting a solidity of from less than 8.0%, to at least 3.0%, and exhibiting a Quality Factor of at least 0.30. Methods of making a relofted web; and, methods of using a relofted web as an air-filtration web, e.g. as a filter media or a layer thereof.

A flat-fold respirator is made from a stiff filtration panel joined to the remainder of the respirator through at least one line of demarcation. The panel contains a porous monocomponent monolayer nonwoven web that contains charged intermingled continuous monocomponent polymeric fibers of the same polymeric composition and that has sufficient basis weight or inter-fiber bonding so that the web exhibits a Gurley Stiffness greater than 200 mg and the respirator exhibits less than 20 mm HO pressure drop. The respirator may be formed without requiring additional stiffening layers, bicomponent fibers, or other reinforcement and can be flat-folded for storage. Scrap from the manufacturing process may be recycled to make additional stiff filtration panel web.

Flat-fold respirator with monocomponent filtration/stiffening monolayer

Spunbonded electret webs comprising polylactic acid fibers, in which at least some of the polylactic acid fibers are meltspun, drawn, charged fibers that include charging additive; and, methods of making such fibers and webs.

Spunbonded web comprising polylactic acid fibers

Wound dressing articles comprising a nonwoven web comprising a plurality of fibers having grafted pendant hydrophilic groups, methods that use high energy irradiation for making a plurality of fibers having grafted pendant hydrophilic groups, useful for making wound dressing articles.

Monomer-grafted fibers and uses thereof

A functionalized nonwoven substrate and methods for preparing the same are described. The functionalized substrates are useful in selectively filtering and removing biological materials, such as biocontaminates, from biological samples.

The disclosure relates to composite nonwoven fibrous web including an embedded phase having a population of particulates forming a substantially continuous three-dimensional network, and a matrix phase comprising a population of fibers forming a three-dimensional network around the particulates. The disclosure also relates to methods of making a composite nonwoven fibrous web including forming an embedded phase having a population of particulates in a substantially continuous three-dimensional network, and forming a matrix phase comprising a population of fibers forming a three-dimensional network around the particulates. Articles made from a composite nonwoven fibrous web prepared according to the methods as described above are also disclosed. In exemplary embodiments, the articles may include gas filtration articles, liquid filtration articles, sound absorption articles, surface cleaning articles, cellular growth support articles, drug delivery articles, personal hygiene articles, and wound dressing articles.

Dimensionally stable nonwoven fibrous webs include a plurality of fibers formed from one or more thermoplastic polyesters and an antishrink additive, preferably in an amount greater than 0% and no more than 10% by weight of the web. The webs have at least one dimension which decreases by no greater than 12% in the plane of the web when heated to a temperature above a glass transition temperature of the fibers. The webs may be used as wipes.
