Abstract

The invention discloses a pearl modified regenerated cellulose fiber and a preparation method thereof. The modified regenerated cellulose fiber contains 1 to 10 weigh percent of pearl powder and 1 to 6 weight percent of mica powder relative to alpha cellulose in the modified viscose. The preparation method comprises the following steps of firstly, uniformly mixing the nanoscale pearl powder and the nanoscale mica powder, and packaging a mixture into honeycomb micropores of honeycomb silicon dioxide to prepare microcapsules; grinding at high speed, then adding caprylic/capric triglyceride which is 3 to 10 weight percent of microcapsules, stirring and infiltrating for 3 to 10 minutes; then dissolving into water, adding an additive, a cross-linking agent and a modifying agent and uniformly mixing to prepare modified emulsion; sufficiently mixing the modified emulsion with a spinning solution by a static or dynamic mixer and then spinning to obtain the modified viscose. The modified fiber disclosed by the invention has efficacy of caring skin, moistening and beautifying and excellent properties of absorbing heat, cooling, resisting ultraviolet rays and the like, and is particularly suitable for summer clothing accessories as well as underclothes such as scarves, scarfs and the like.

Description

technical field [0001] The invention relates to the technical field of functional cellulose fibers, in particular to pearl modified regenerated cellulose fibers. Background technique [0002] With the improvement of people's living conditions, it is particularly important to improve the quality of life. The development of new functional cellulose fibers can not only meet people's requirements for textiles to keep warm and comfortable, but also have good health care effects, which is in line with the concept of healthy life. [0003] At present, most of the production of pearl fiber is to add nano-scale pearl powder into the viscose solution during viscose spinning, so that the pearl particles are combined into the fiber. Because pearls are rich in various amino acids and trace elements, the pearl fiber fabric When in contact with the human body, it exerts a good beauty and health care effect. Due to the defects in the process, the current production method has uneven dispe...
