Problems solved by technology

CN101343780A discloses a viscose fiber containing aloe and a preparation method thereof. The fiber is prepared by wet spinning after the aloe extract is directly mixed with the viscose spinning liquid to obtain the aloe viscose fiber. The shortcoming of the method is that The aloe extract is directly added to the viscose spinning solution for blending. The vitamins and amino acids contained in the aloe will be destroyed under the condition of strong alkali, resulting in a large loss of effective substances, and the ideal skin care and moisturizing effect cannot be obtained.
Patent No. CN1664186A discloses a kind of preparation method of aloe viscose fiber, this method directly joins aloe vera gel in the viscose spinning solution and carries out wet spinning and prepares aloe viscose fiber, and this method is also in strong alkali If the aloe gel is directly added to the spinning solution, the high-concentration lye will destroy the physical and chemical properties of the aloe gel, thereby affecting the performance of the aloe viscose fiber

Abstract

The invention discloses regenerated cellulose fibers containing ceramide micro-capsules and a preparation method of the regenerated cellulose fibers. Raw materials of the regenerated cellulose fiberscomprise viscose spinning fluid and the ceramide micro-capsules, and capsule cores of the ceramide micro-capsules comprise ceramide and glycerinum. The preparation method comprises the steps of mixingceramide micro-capsule dispersion fluid with the viscose spinning fluid and then carrying out wet spinning on the mixture to obtain the final product. The ceramide is prepared into the micro-capsulesby a micro-capsule wrapping technology, and then the micro-capsules are added in the viscose spinning fluid to obtain skin-caring and moisturizing viscose fibers.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to a regenerated cellulose fiber containing ceramide microcapsules and a preparation method thereof. Background technique [0002] With the continuous development of the economy and the continuous upgrading of domestic consumption levels, people's demand for textiles is also increasing, especially for textiles with special functions. The demand is increasing day by day. Therefore, various functional textiles have emerged in the domestic market in recent ten years, such as various products such as antibacterial and anti-mite, skin care and moisturizing, and safety protection. [0003] At present, the production of functional textiles can be roughly divided into two technologies: one is to carry out functional finishing on the fabric, mainly in the process of finishing the fabric after the fabric is impregnated, dried or coated, and the additives with special functions are sorted int...
