Abstract

The invention relates to a temperature-regulating antibacterial pearl regenerated cellulose fiber and a preparation method thereof. The preparation method includes the steps of: preparing temperature-regulating pearl micro-capsules; preparing an additive mother liquid; preparing a blend spinning solution; performing spinning; and performing after-treatment. In the invention, the temperature-regulating pearl micro-capsule is composed of a composite core material, which is formed from pearl powder and paraffin in a blending absorption manner, and a wall material composed of a high-molecular polymer. The mass ratio of the composite core material to the wall material is 0.3-3:1. The pearl powder is not more than 1.2 [mu]m in average particle size. The micro-capsule is not more than 3 [mu]m in average particle size. The preparation method solves the technical problems that a product in the prior art causes discomfort and reduction of health-caring functions in winter, reduction on production efficiency and increase on raw materials cost due to sediment of pearl powder granules during the production process. The preparation method improves the antibacterial effect of the product.

Description

technical field [0001] The invention belongs to the field of textiles, and relates to a temperature-regulating antibacterial pearl regenerated cellulose fiber and a preparation method thereof. Background technique [0002] At present, with the improvement of people's living standards, consumers have higher and higher requirements for the functionality and comfort of textiles, and the demand for antibacterial, comfortable and health care textiles is increasing day by day. Regenerated cellulose fiber textiles are chemical fibers obtained by spinning natural cellulose and / or cotton linters through a series of processing procedures to prepare a spinning solution. The textile products made of them have the characteristics of soft moisture absorption and comfort; Recognized as a precious health care product, it has miraculous effects such as beautifying the skin, delaying aging, clearing fire and detoxification. The development of pearl regenerated cellulose textiles has enriched...
