A composition is described comprising semicrystalline polylactic acid polymer; polyvinyl acetate polymer having a glass transition temperature (Tg) of at least 25&#xb0; C.; plasticizer; and optionally amorphous polylactic acid polymer. In another embodiment the composition further comprises nucleating agent. Also described are films comprising the composition as well as articles, such as a tape or sheet, comprising the film described herein and a layer of pressure sensitive adhesive disposed on the film.

Compositions and films comprising polylactic acid polymer, polyvinyl acetate polymer and plasticizer

An air filter includes filter media, a sensor, and circuitry coupled to the sensor, the circuitry configured to receive data from the sensor representative of the condition of the filter media and wirelessly transmit such data. The data may be received by a device with a display to use the information to present an indication of the filter media condition to a user.

Air filter condition sensing

Devices, systems and methods for obtaining data representative of the condition of an air filter media of an air filter installed in a powered air-handling system, and for using such data to present an indication of the air filter media condition to a user. The devices, systems and methods use pressure information representative of at least a downstream pressure of the powered air-handling system.

A multi-component fiber including at least first and second components. In some cases, at least a portion of the first component is opaque and microporous, and the second component is different from the first component. In some cases, at least a portion of the second component can be seen through at least a portion of the first component. A fiber having an opaque, microporous region and a see-through region of lower porosity is also disclosed. Fibrous webs including such fibers are also disclosed. In some cases, the fibrous web has at least one first region where first portions of the multiple fibers are opaque and microporous and at least one second region where second portions of the multiple fibers form a see-through region of lower porosity. Articles and laminates including the fibrous webs are disclosed. Methods of making the fibers, fibrous webs, and articles are also disclosed.

Fibers and articles including them

A composition is described comprising semicrystalline polylactic acid polymer; polyvinyl acetate polymer having a glass transition temperature (Tg) of at least 25 C; plasticizer; and optionally amorphous polylactic acid polymer. In another embodiment the composition further comprises nucleating agent. Also described are films comprising the composition as well as articles, such as a tape or sheet, comprising the film described herein and a layer of pressure sensitive adhesive disposed on the film.

The present disclosure describes a display system including a liquid crystal display panel and a light source emitting light capable of emitting light. A nonwoven diffuser element is disposed between the light source and the liquid crystal display panel. The polymeric nonwoven diffuser is non-orientated and has a fiber diameter of less than 50 micrometers, a fiber aspect ratio of length/diameter of greater than 5 and a basis weight in a range from 10 to 80 grams/meter.

A method of forming disposable absorbent articles includes forming at least two different types of absorbent articles on a single product line. Each type of absorbent article has an absorbent structure that differs from the absorbent structure of at least one other absorbent article type on the product line. The method further includes creating a visual distinction between the different types of absorbent articles and packaging the different types of absorbent articles in a single package.

Absorbent articles in a unitary package

A biodegradable nonwoven laminate is provided. The laminate comprises a spunbond layer formed from substantially continuous filaments that contain a first aliphatic polyester having a melting point of from about 50&#xb0; C. to about 160&#xb0; C. The meltblown layer is formed from microfibers that contain a second aliphatic polyester having a melting point of from about 50&#xb0; C. to about 160&#xb0; C. The first aliphatic polyester, the second aliphatic polyester, or both have an apparent viscosity of from about 20 to about 215 Pascal-seconds, as determined at a temperature of 160&#xb0; C. and a shear rate of 1000 sec-1. The first aliphatic polyester may be the same or different than the second aliphatic polyester.

Biodegradable nonwoven laminate

A biodegradable nonwoven web comprising substantially continuous multicomponent filaments is provided. The filaments comprise a first component and a second component. The first component contains at least one high-melting point aliphatic polyester having a melting point of from about 160&#xb0; C. to about 250&#xb0; C. and the second component contains at least one low-melting point aliphatic polyester. The melting point of the low-melting point aliphatic polyester is at least about 30&#xb0; C. less than the melting point of the high-melting point aliphatic polyester. The low-melting point aliphatic polyester has a number average molecular weight of from about 30,000 to about 120,000 Daltons, a glass transition temperature of less than about 25&#xb0; C., and an apparent viscosity of from about 50 to about 215 Pascal-seconds, as determined at a temperature of 160&#xb0; C. and a shear rate of 1000 sec.

Biodegradable continuous filament web

A multicomponent fiber that contains a high-melting aliphatic polyester and a low-melting aliphatic polyester is provided. The multicomponent fibers are substantially biodegradable, yet readily processed into nonwoven structures that exhibit effective fibrous mechanical properties.

Biodegradable multicomponent fibers

The present disclosure generally relates to absorbent articles. More specifically, the present disclosure relates to an absorbent article comprising a surge management layer comprising a nonwoven web. The nonwoven web includes a filler fiber and a binder fiber. A portion of the cross-sectional area of the filler fiber is hollow, and the binder fiber includes a sheath component and a core component.
