Multi-component fibers having enhanced reversible thermal properties
First Claim
1. A multi-component fiber, comprising:
- a fiber body formed from a plurality of elongated members, at least one of the plurality of elongated members comprising a temperature regulating material having a latent heat of at least 40 J/g and a transition temperature in the range of 22°
C. to 40°
C. ,wherein the temperature regulating material has a partial affinity or partial compatibility with the at least one of the plurality of elongate members,wherein the temperature regulating material forms at least one discrete domain within the at least one of the plurality of elongated members,wherein the plurality of elongated members are arranged in one of an island-in-sea configuration, a segmented-pie configuration, a core-sheath configuration, a side-by-side configuration, and a striped configuration.

Abstract
Multi-component fibers having enhanced reversible thermal properties and methods of manufacturing thereof are described. In one embodiment, a multi-component fiber includes a fiber body formed from a set of elongated members, and at least one of the set of elongated members includes a temperature regulating material having a latent heat of at least 40 J/g and a transition temperature in the range of 22° C. to 40° C. The temperature regulating material provides thermal regulation based on at least one of absorption and release of the latent heat at the transition temperature. The multi-component fiber can be formed via a melt spinning process or a solution spinning process and can be used or incorporated in various products where a thermal regulating property is desired. For example, the multi-component fiber can be used in textiles, apparel, footwear, medical products, containers and packagings, buildings, appliances, and other products.
