Multi-component fibers having enhanced reversible thermal properties
First Claim
1. A multi-component fiber, comprising:
- a plurality of island members, at least one of the plurality of island members comprising a raw or non-encapsulated phase change material having a latent heat of at least 40 J/g and a transition temperature in the range of 10°
C. to 50°
C., wherein the raw or non-encapsulated phase change material forms at least one discrete domain within the at least one of the plurality of island members and provides thermal regulation based on at least one of absorption and release of the latent heat at the transition temperature; and
a sea member surrounding the plurality of island members and forming an exterior of the multi-component fiber.

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.
