A yarn includes at least one continuous PGS fiber. A continuous poly(glycerol sebacate) (PGS)/alginate fiber forming system includes a feeding tank holding a polymeric solution of alginate and PGS, a pump, a spinneret, a first coagulation bath, a first winder, a second coagulation bath, a second winder, and a bobbin winder, the system forming at least one continuous PGS/alginate fiber from the polymeric solution of alginate and PGS.

A method of creating a soft and lofty continuous fiber nonwoven web is provided. The method includes providing first and second, different molten polymers to a spinneret defining a plurality of orifices and flowing a fluid intermediate the spinneret and a moving porous member. The method includes using the fluid to draw the first and second molten polymers, in a direction toward the porous member, through at least some of the plurality of orifices to form a plurality of individual continuous fiber strands. The method includes depositing the continuous fiber strands onto the porous member at a first location to produce an intermediate continuous fiber nonwoven web, and intermittently varying, in at least two different zones, a vacuum force applied to the moving porous member and to the intermediate web downstream of the first location and without the addition of more continuous fibers and without any heat applied.

An object of the invention is to provide conjugate fibers with an encapsulated liquid crystal, which can be used for forming a flexible liquid crystal display device, and the conjugate fibers without disturbance of arrangement of liquid crystal molecules within the fibers. The conjugate fibers according to the invention are sheath-core conjugate fibers having a liquid crystal composition as a core component, and the conjugate fibers with the encapsulated liquid crystal, in which the liquid crystal composition contains a halogen-containing liquid crystal compound.
