A flame resistant fabric containing a plurality of warp elements comprising flame resistant (FR) yarns extending in a warp direction and a plurality of filling elements comprising FR yarns extending in the fill direction transverse to the warp direction in interwoven relation to the warp elements. At least a portion of the FR yarns in the fill and/or warp direction comprise intermingled FR yarns. The intermingled FR yarns contain at least 2 plies, at least one of the plies contain staple fibers or continuous multifilaments and at least one of the plies contain FR fibers. The plies are intermingled together with a portion of the staple fibers or continuous multifilaments of the first ply entangled with the second ply.

An implantable, pliable silk device (e.g., in a form of a knitted mesh) for use in human soft tissue support and/or repair that provides stretch or pliable properties, e.g., multi-directional elongation properties. Such a device permits physicians or users to alter or manipulate the device dimension and/or shape at the time of device implantation, thereby permitting the device to conform to the contour of a target area or tissue more easily and providing more precise positioning of the device over the target area or tissue. In some embodiments, the implantable pliable silk device comprises a knit pattern feature that substantially prevents unraveling and preserves the stability of the mesh when cut. For example, the pliable silk device is a knitted mesh comprising at least two yarns laid in a knit direction and engaging each other to define a plurality of nodes.

A process for texturing a multicomponent fiber having a shaped cross section is provided. The process comprises: (A) providing a multicomponent fiber having a shaped cross section and at least one water dispersible polymer; and a plurality of domains comprising one or more water non-dispersible polymers, wherein said domains are substantially isolated from each other by said water dispersible polymer intervening between said domains; and (B) passing the multicomponent fiber through a first zone comprising a first heating device and a twisting unit, wherein the first heating device has a heating temperature that is at least 10% less than the temperature used for a fiber without the water dispersible component having the same water non-dispersible polymer, same number of total filaments in the fiber, and the same total denier for a given type of equipment and process conditions.

An article is provided comprising a multicomponent fiber having a shaped cross section, wherein the multicomponent fiber comprises: (A) at least one water dispersible polymer; and (B) a plurality of domains comprising one or more water non-dispersible polymers, wherein said domains are substantially isolated from each other by said water dispersible polymer intervening between said domains; and wherein said water dispersible polymer is present at the perimeter of the outside cross-section of said multicomponent fiber in a proportion of not greater than 55% water dispersible polymer.
