Phase-change temperature-regulating fiber as well as preparation method and preparation equipment thereof

Abstract

By reducing the extrusion melting temperature of a skin layer raw material and a core layer base material in a traditional skin-core composite spinning process, the content of a phase-change material in phase-change temperature-adjusting fiber is increased, the risk of leakage of the phase-change material in the phase-change temperature-adjusting fiber is reduced, and the quality of the phase-change temperature-adjusting fiber is improved; and the phase-change temperature-adjusting fiber has relatively good practical value and popularization and application prospects.

Description

technical field [0001] The invention relates to a phase-change temperature-regulating fiber, a preparation method and preparation equipment thereof. Background technique [0002] Phase-change temperature-regulating fiber is a kind of heat-storing and temperature-regulating functional fiber developed by utilizing the characteristics of releasing or absorbing latent heat and maintaining temperature during the phase change of substances. Applying it to textiles can absorb heat and store it inside the textile, or release the heat stored in the textile to form its own relatively independent microclimate, thereby achieving a stable regulation function. In addition to being used as spacesuits, phase-change temperature-regulating fibers can also be used in sportswear, underwear, and bedding. [0003] The method for preparing the phase-change temperature-regulating fiber includes: a blending method, a microcapsule method and a composite spinning method. Among them, the blending met...

Problems solved by technology

However, in the microcapsule method, the larger microcapsules will be filtered out and cannot enter the fiber, resulting in a smaller fiber phase change enthalpy; the poor compatibility between the microcapsule and the fiber matrix leads to the problem of low fiber strength.
