Abstract: 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.

Abstract: Dimensionally stable nonwoven fibrous webs include a multiplicity of continuous fibers formed from one or more thermoplastic polyesters and polypropylene 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 10% in the plane of the web when heated to a temperature above a glass transition temperature of the fibers. A spunbond process may be used to produce substantially continuous fibers that exhibit molecular orientation. A meltblown process may be used to produce discontinuous fibers that do not exhibit molecular orientation. In some embodiments, the fibers comprise a viscosity modifier and/or an anionic surfactant. The webs may be used as articles for filtration, sound absorption, thermal insulation, surface cleaning, cellular growth support, drug delivery, personal hygiene, medical apparel, or wound dressing.
Abstract translation: 尺寸稳定的非织造纤维幅材包括由一种或多种热塑性聚酯和聚丙烯形成的多种连续纤维，其量大于纸幅重量的0％且不大于10％。 当幅材加热至高于纤维的玻璃化转变温度的温度时，幅材具有至少一个尺寸，其在幅材的平面中减小不超过10％。 纺粘方法可用于产生显示分子取向的基本上连续的纤维。 可以使用熔喷法来制造不显示分子取向的不连续纤维。 在一些实施方案中，纤维包含粘度调节剂和/或阴离子表面活性剂。 纤维网可以用作过滤，吸声，隔热，表面清洁，细胞生长支持，药物递送，个人卫生，医疗服装或伤口敷料的制品。

Abstract: A sample collection device includes a housing including an exhalation portion and a coupling portion. The coupling portion can be coupled with/to a sample collection tube. An airflow path extends through the housing. The device further includes porous sample collection media partially disposed between within the housing and arranged to occlude the airflow path. The porous sample collection includes nonwoven material and may include polylactic acid, polypropylene, or a combination thereof. The housing can be a single piece, part, or component, or can be multiple pieces, parts, components, or portions. In an embodiment of a two-piece housing, the first part includes an exhalation piece (e.g., a mouthpiece or nosepiece) and the second part includes a coupling end constructed for coupling with a sample collection tube. A method of obtaining a sample using the sample collection device includes breathing into the exhalation piece or portion to collect a sample on the porous sample collection media; coupling the second part or portion with a sample collection tube; and transferring the collected sample on the porous sample collection media into the sample collection tube.

Abstract: A sample collection device including a housing extending from a mouthpiece portion to an air outlet portion. The housing defines an airflow channel from the mouthpiece portion to the air outlet portion. The mouthpiece portion is configured to receive an h exhalation airflow. A porous sample collection media is disposed within the housing and along the airflow channel. A fluid inlet port defines an aperture through the housing and is adjacent to the porous sample collection media. The fluid inlet port is configured to direct id onto the porous sample collection media. A metered fluid dose element is attached to the fluid inlet port. The metered fluid dose element is configured to dispense a metered volume of fluid into the fluid inlet port.
