A kind of phase change temperature regulating fiber blended yarn

Abstract

The invention discloses a phase-change temperature-regulating fiber blended yarn and a preparation method thereof. Firstly, paraffin, graphite powder and methyl-2,4-diisocyanate are mixed and stirred at high speed to obtain phase-change temperature-regulating microcapsules. The prepared phase-change temperature-regulating microcapsules are added to nano-silver hydrogel to obtain modified nano-silver hydrogel, and then modified sodium alginate hydrogel is obtained by adding chitosan to sodium alginate hydrogel, The modified nano-silver hydrogel and modified sodium alginate hydrogel are mixed into the spinning stock solution, and composite fibers are made by electrospinning, and the composite fibers are helically twisted with wool fibers and combed cotton to obtain phase-change temperature-regulating fibers blended yarns. The invention provides a phase-change temperature-regulating fiber blended yarn and a preparation method thereof. The prepared phase-change temperature-regulating fiber blended yarn has good temperature-regulating and antibacterial properties, and is more washable while retaining good fabric properties. Excellent water absorption and air permeability, with high practicality.

Description

technical field

[0001] The invention relates to the technical field of blended yarns, in particular to a phase-change temperature-regulating fiber blended yarn and a preparation method thereof. Background technique

[0002] Phase-change temperature-regulating fiber blended yarn refers to a high-tech fiber blended yarn that can respond to external temperature changes obtained by blending phase-change temperature-regulating fibers with other types of yarns. The fabric made of the blended yarn can undergo phase reversible reactions according to temperature changes, thereby improving the comfort of clothing. When the temperature rises, it absorbs and stores heat, and the phase-change substance changes from solid to liquid. When the temperature drops, the stored heat is released, the phase change material changes from liquid to solid, and the temperature around the fiber is kept constant to a certain extent through the heat-absorbing and exothermic process. This performance is n...
