Abstract
Fibers, fabrics, mattresses and processes of making the fibers generally include a microencapsulated phase change material; and a polymer, wherein the microencapsulated phase change material is greater than 50 percent by weight of the fiber. The process for making the fibers is a dry jet/wet spinning process free of sonication.
Claims31
A microencapsulated phase change material fiber composite comprising:
- microencapsulated phase change material;
- and
- a polymer, wherein the microencapsulated phase change material is greater than 50 percent by weight of the fiber.
A fabric comprising:
- a plurality of fibers, wherein the fibers comprise microencapsulated phase change material;
- and
- a polymer, wherein the microencapsulated phase change material is greater than 50 percent by weight of the fiber.
A mattress comprising:
- at least one fabric layer in contact and/or in proximity to an end user, wherein the at least one fabric layer comprises a plurality of fibers, wherein the fibers comprise microencapsulated phase change material;
- and a polymer, wherein the microencapsulated phase change material is greater than 50 percent by weight of the fiber.
A dry jet/wet spinning process of manufacturing a fiber comprising:
- providing a spin dope, wherein the spin dope comprises microencapsulated phase change materials, a polymer, a water soluble surfactant, and a solvent, wherein the polymer is soluble in the solvent and the microencapsulated phase change material is uniformly dispersed in the spin dope without sonication,
- pumping the spin dope into a multi-hole spinneret to extrude filaments therefrom;
- feeding the filaments into a coagulation bath system to form microencapsulated phase change material fiber composites and removing residual solvent and water soluble surfactant, wherein the spinneret is spaced apart from the coagulation bath by an air gap;
- and
- drawing the fiber, wherein the microencapsulated phase change material is greater than 50 percent by weight of the fiber.
