preparation example Construction

[0039] The invention provides a method for preparing viscose fibers with multiple functions such as temperature control and antibacterial, comprising the following steps:

[0040] mixing the phase-change microcapsule emulsion, the graphene dispersion and the viscose solution to obtain a spinning solution; the phase-change microcapsules include a polymer capsule wall and a phase-change material embedded in the polymer capsule wall; the The phase change material is selected from n-tetradecane, n-pentadecane, n-hexadecane, n-heptadecane, n-octadecane, n-nonadecane, n-eicosane and polyethylene glycol E600 or more;

[0041] The spinning liquid enters the coagulation bath through the spinneret, and the as-spun fibers are separated out, and then the multifunctional viscose fibers are obtained through drafting and winding.

[0042] The viscose fiber prepared by the invention has multiple functions such as temperature control and antibacterial, and can be used as clothing fabrics to k...

Abstract

The invention provides a multifunctional viscose with functions such as temperature regulation and bacterium resistance, a preparation method of the viscose and a fabric. The multifunctional viscose comprises a graphene component and phase-change microcapsule particles; the phase-change microcapsule particles comprise polymer capsule walls and phase-change materials embedded in the polymer capsule walls; the phase-change materials are selected from one or more of n-tetradecane, n-pentadecane, n-hexadecane, n-heptadecane, n-octadecane, n-nonadecane, n-eicosane and polyethylene glycol E600. According to the multifunctional viscose, by mainly using the heat storage function of the phase-change materials and the heat conduction function of graphene, the viscose can regulate the temperature and balance the heat. The graphene component has the bacterium resistance and far-infrared transmission capacities. When the multifunctional viscose is used as the garment fabric, the temperature and humidity micro-environment of the human body can keep balance, the human body keeps a good and comfortable wearing environment as long as possible, the multifunctional viscose has the bacterium resistance function, and the health of the human body is protected.

Description

technical field [0001] The invention relates to the technical field of functional viscose fibers, in particular to a viscose fiber with multiple functions such as temperature regulation and antibacterial, a preparation method and a fabric. Background technique [0002] As the greenhouse climate problem becomes more and more serious, the summer temperature frequently breaks the history. When the sun is strong in summer, people will sweat outdoors due to the high ambient temperature and cause discomfort, which will affect the thermal physiological comfort of the human body. Human sweat contains a lot of minerals, amino acids and other substances that are beneficial to the body. When sweating, it is lost with the sweat. If the fluid is not replenished in time, it will lead to a decrease in blood volume, a faster heart rate, a decrease in perspiration rate, and a decrease in heat dissipation capacity; Elevated blood pressure will lead to electrolyte imbalance and acid-base balan...
