Abstract

The invention discloses a temperature-regulating aromatic fiber. In raw materials of the temperature-regulating aromatic fiber, polyurea-melamin resin wall material cetane phase change microcapsules account for 10 to 15 percent of the mass of spinning solution, and nano-aromatic microcapsules account for 5 to 10 percent of the mass of the spinning solution, wherein the phase change temperature of the polyurea-melamin resin wall material cetane phase change microcapsules is between 10 and 40 DEG C, and the enthalpy of phase change is between 100 and 180J / g. The preparation method of the temperature-regulating aromatic fiber comprises the following steps: uniformly mixing the polyurea-melamin resin wall material cetane phase change microcapsules, the nano-aromatic microcapsules and viscose solution; pressing into a coagulation bath by virtue of spinning for spinning formation; and preparing the temperature-regulating aromatic fiber through moist heat stretching formation, refining treatment and drying.

Description

[0001] technical field [0002] The invention belongs to the field of textiles, and in particular relates to a functional fiber. [0003] Background technique [0004] The air-conditioning fiber is Outlast fiber, and its technology was developed by NASA for the moon landing program. The purpose is to make moon landing clothing for astronauts, including gloves, socks, underwear, etc., and later developed to be used for ordinary clothing, especially outdoor clothing, including ski jackets, pants, sweaters, etc. Outlast air-conditioning fiber is a new type of "smart" fiber, successfully developed in 1988, first used commercially in 1994, used in outdoor clothing in 1997, and is now widely used in fashion and bedding. [0005] Outlast fiber temperature regulation principle: The key to Outlast fiber technology is the use of heat-sensitive phase-change materials wrapped in microcapsules. This material has the function of absorbing, storing and releasing heat in the form of laten...
