Abstract

The invention discloses a phase-change blend fiber. A spinning solution of the fiber contains phase-change materials such as paraffin hydrocarbons and polyols; the fiber is characterized in that the spinning solution comprises components by weight as follows: 1-8 parts of the phase-change materials, 6-9 parts of fibroin, 750-990 parts of water-soluble materials, 30-60 parts of high-molecular polymers and 10-15 parts of polylysine.

Description

[0001] This application is a divisional application of the invention patent application with the application number 2014103692593, the application date is July 30, 2014, and the invention title is "a phase change blended fiber and its manufacturing method". technical field [0002] The invention relates to a phase-change blended fiber, which belongs to the field of spinning preparation and application of phase-change materials. Background technique [0003] Phase change fiber is a kind of heat storage and temperature regulating functional fiber developed by utilizing the characteristics of releasing or absorbing latent heat and keeping temperature unchanged during the phase change of matter. Phase change is manifested in the change of three states of gas, solid and liquid, as well as physical processes such as crystallization, crystal transformation to hydrocarbon, and crystal melting. The phase change from solid to solid shows different heat absorption and heat release func...
