Aspects herein are directed to a recyclable, asymmetrical-faced composite nonwoven textile suitable for use in apparel and other articles and methods of making the same. In example aspects, the asymmetrical-faced composite nonwoven textile includes a first face formed, at least in part from a first entangled web of fibers and an opposite second face formed, at least in part from a second entangled web of fibers. When incorporated into an article of apparel, the first face forms an outer-facing surface of the article of apparel, and the second face forms an inner-facing surface of the article of apparel. The first face includes features making it suitable to form the outer-facing surface such as resistance to abrasion, and the second face includes features making it suitable to form an inner-facing surface such as a soft hand.

Aspects herein are directed to a composite nonwoven textile suitable for use in apparel and other articles that are resistant to pilling. The composite nonwoven textile may be finished by one or more of applying a chemical binder to a first face of the composite nonwoven textile and forming thermal bonding sites. The chemical binder and the thermal bonding sites help to secure fiber terminal ends and minimize the formation of pills.

The present application describes a surgical swab composed of two or more outer layers made of non-woven fabric and an inner layer of a textile polymer net, with or without x-ray detectable thread, which can be obtained, for example, by a process of knitting or weaving. The textile net can present in its composition materials with high elasticity such as elastane or alternatively combinations of materials that allow shrinking after heat treatment such as the polyamide or polyamide and polyester or even polyamide and cotton. In the present application, it is also described the production process of this surgical swab which, after the junction and overlapping of the non-woven fabric layers and the inner layer of textile polymer net, comprises ultrasound welding of the layers. The surgical swabs of this application present improved performance features and the production process involved is simple, economical and automated.

Energy mechanism assemblies and methods of operating such assemblies are described. One method of providing energy to an item may comprise positioning an item proximate an energy mechanism assembly comprising a first and second energy mechanism and a translation system configured to move the second mechanism along between a first position and a second position along a first axis and a second axis, positioning the item between the first and second mechanisms, moving the second mechanism from the first position to the second position, moving the second mechanism along the second axis for a first length while the second mechanism is in contact with the item; and providing energy to the item at least while the second mechanism contacts the item.

A chemical barrier fabric and a method of manufacturing the fabric is provided. The chemical barrier fabric includes at least first and second chemical barrier layers which have an interfacial region therebetween and which are intermittently point bonded providing a point-bonded area which is in the minority and an un-bonded area which is in the majority in the interfacial region. The chemical barrier layers typically comprise single layer polymer films and/or co-extruded layers. A non-woven layer may also be point-bonded to either the first or the second chemical barrier layer to give support to the fabric.
