Abstract

The invention discloses a preparation method for a fiber having functions of thermal storage and temperature regulation. The method comprises the following steps: 1, preparation of a master batch having the functions of thermal storage and temperature regulation: blending a thermal-storage and temperature-regulation agent and polyvinyl, drying, pouring into a screw type extruder for smelting, blending and extruding, and performing granulation to obtain the master batch having the functions of thermal storage and temperature regulation; 2, production of the fiber having the functions of thermal storage and temperature regulation: blending and slicing the obtained master batch and a fiber, and performing spinning, reeling and stretching to form the fiber having functions of thermal storage and temperature regulation, wherein the thermal-storage and temperature-regulation agent comprises the following components by weight: 75-90 parts of nonadecane, 30-50 parts of molybdenum oxide, 15-25 parts of titanium dioxide, 2-5 parts of aluminium-zirconium acid ester couplint agent, and 0.5-1.2 parts of polyacrylate sodium dispersant. According to the method, the thermal-storage and temperature-regulation agent and the fabric fibers can be firmly combined, so that the durability is high, and the superior thermal-storage and temperature-regulation function for the fabric fiber is achieved.

Description

technical field [0001] The invention relates to a preparation method of heat storage and temperature regulating fibers. Background technique [0002] Heat storage and temperature regulating fiber is a new type of fiber with two-way temperature regulating effect. According to the change of the external environment temperature, it can absorb heat from the environment and store it inside the fiber, or release the heat stored in the fiber, and form a microclimate with a basically constant temperature around the fiber, thereby realizing the temperature regulation function. This heat-absorbing and exothermic process of heat-storing and temperature-regulating fibers is automatic, reversible, and infinite. [0003] The difference between heat storage and temperature regulating fibers and traditional fibers lies in the different insulation mechanisms. Traditional fiber insulation mainly uses heat insulation to avoid excessive skin temperature drop, and the heat insulation effect ma...
