The present invention provides threads of hyaluronic acid, and/or derivatives thereof, methods of making thereof and uses thereof, for example, in aesthetic applications (e.g., dermal fillers), surgery (sutures), drug delivery, etc.

Clothing articles formed of melting yarn and non-melting yarn, and system and method of producing such clothing articles. A clothing article includes: a first garment-region which consists of, exclusively, non-melting yarn, wherein the first garment-region has a first level of rigidity; and a second garment-region which comprises a mixture of both (i) non-melting yarn and (ii) stiffed melted-yarn, wherein the second garment-region has a second level of rigidity which is greater than the first level of rigidity. A garment includes multiple garment-regions having different levels of rigidity, wherein each garment-region consists of a different ratio of non-melting yarn to stiffed melted-yarn.

A consumable filament for use in an extrusion-based additive manufacturing system, where the consumable filament comprises a core portion of a first thermoplastic material, and a shell portion of a second thermoplastic material that is compositionally different from the first thermoplastic material, where the consumable filament is configured to be melted and extruded to form roads of a plurality of solidified layers of a three-dimensional object, and where the roads at least partially retain cross-sectional profiles corresponding to the core portion and the shell portion of the consumable filament.

The present disclosure generally relates to extrusion die systems. In particular, the present disclosure relates to the cyclical extrusion of materials to generate small sized grain features, generally in the range of nanosized grain features, in a tubular or profile shape, in which the individual nanolayers possess pores and/or polymer crystals oriented parallel to the extrusion flow direction and including products with enhanced permeation properties.

A method of drawing a material into sheet form includes forming a preform comprising at least one material as a large aspect ratio block wherein a first transverse dimension of the preform is much greater than a second transverse dimension substantially perpendicular to the first transverse dimension. A furnace having substantially linearly opposed heating elements one spaced from the other is provided and the heating elements are energized to apply heat to the preform to create a negative thermal gradient from an exterior surface along the first transverse dimension of the preform inward toward a central plane of the preform. The preform is drawn in such a manner that the material substantially maintains its first transverse dimension and deforms across its second transverse dimension.

The instant invention provides bi-component fibers and fabrics made therefrom. The bi-component fiber according to the present invention comprises: (a) from 5 to 95 percent by weight of a first component comprising at least one or more first polymers, based on the total weight of the bi-component fiber; (b) from 5 to 95 percent by weight of a second component comprising at least an ethylene-based polymer composition, based on the total weight of the bicomponent fiber, wherein said ethylene-based polymer composition comprises; (i) less than or equal to 100 percent by weight of the units derived from ethylene; and (ii) less than 30 percent by weight of units derived from one or more -olefin comonomers; wherein said ethylene-based polymer composition is characterized by having a Comonomer Distribution Constant in the range of from greater than from 100 to 400, a vinyl unsaturation of less than 0.1 vinyls per one thousand carbon atoms present in the backbone of the ethylene-based polymer composition; a zero shear viscosity ratio (ZSVR) in the range from 1 to less than 2; a density in the range of 0.920 to 0.970 g/cm.sup.3, a melt index (I.sub.2) in the range of from 10 to 40 g/10 minutes, a molecular weight distribution (M.sub.w/M.sub.n) in the range of from 1.8 to 3.0, and a molecular weight distribution (M.sub.z/M.sub.w) in the range of from less than 2; and wherein said bi-component fiber has a denier per filament in the range of from 0.5 to 10 g/9000 m.

The present invention relates to a dynamic fiber/yarn capable of changing in response to external stimuli. The fiber/yarn in accordance with the present invention undergoes a radial symmetric change. The fiber/yarn in accordance with the present invention may be heat sensitive, moisture sensitive, magnetic field sensitive, electromagnetic field sensitive, etc.

Disclosed herein are polyesters and fibers made therefrom. The fiber comprises a polymer, poly(trimethylene furandicarboxylate) (PTF), and PTF based copolymers.
