The present invention refers to a nonwoven web with multicomponent fibers having at least a first and a second component which differ from each other in color. The nonwoven web is pattern bonded to obtain bonded areas have a different color versus the unbonded areas.

A textile graphene component thermal fiber, or filament yarn, is able to be integrated into a textile, for example performance knits, woven and non-woven garments and linens, in order to conduct absorb or emit heat in order to regulate the body temperature for a user. The textile graphene component thermal fiber is able to absorb thermal energy and optimally conduct the thermal energy for extended periods of time. The textile graphene component thermal fiber includes a quantity of polymers, a first quantity of graphene, and a second quantity of graphene The quantity of polymers and the first quantity of graphene are mixed into a polymeric sheath. The second quantity of graphene and the quantity of thermally conductive substances are mixed into a thermal-conducting core. The polymeric sheath encloses the thermal conducting core in order to form the textile bi-component thermal fiber.

A multi-component fiber including at least first and second components. In some cases, at least a portion of the first component is opaque and microporous, and the second component is different from the first component. In some cases, at least a portion of the second component can be seen through at least a portion of the first component. A fiber having an opaque, microporous region and a see-through region of lower porosity is also disclosed. Fibrous webs including such fibers are also disclosed. In some cases, the fibrous web has at least one first region where first portions of the multiple fibers are opaque and microporous and at least one second region where second portions of the multiple fibers form a see-through region of lower porosity. Articles and laminates including the fibrous webs are disclosed. Methods of making the fibers, fibrous webs, and articles are also disclosed.

There is provided an apparatus for drawing a fibre, the apparatus comprising, a first outlet for dispensing a volume of a first polyionic polymer solution; and a second outlet for dispensing a volume of a second oppositely charged polyionic polymer solution; said second outlet disposed adjacent to the first outlet such that the polymer solutions dispensed therefrom are capable of contacting each other to form a fused droplet comprising a polyelectrolyte complex interface separating the first polyionic and second polyionic polymer solutions; wherein the fused droplet is arranged to move along a fibre drawing path under gravitational force in an opposing direction from the first and second outlets such that nascent fibre is drawn from the polyelectrolyte complex interface. There is also provided a method of drawing the fibre.

A network of microfibers are fabricated with a core-shell construction from sustainable materials, where the core includes a phase-change material, such as coconut oil, and the shell includes a biomass, such as cellulose. The microfibers are made via a wet-wet electrospinning process utilizing a coaxial spinneret with an inner conduit and an outer conduit. The biomass and the phase-change material are coaxially extruded into a coagulation bath including a mixture of ethanol and water. The collected microfibers exhibit a beaded structure of PCM aggregates and biomass connecting regions between the aggregates and are effective to aid in the thermoregulation of the immediate environment surrounding the network. The microfibers are suitable for use in a variety of sustainable products such as wearable thermoregulating textiles, wall/ceiling panels, insulation, packaging material, and more.
