Description

Technical Field

[0001] The present invention relates to the technical field of viscose macro biofibers, and particularly to viscose macro biofibers containing antioxidant active components and a method for preparing the same.

Background Art

[0002] Viscose fiber, also called viscose yarn, is made from natural fibers such as wood fiber and cotton staple fiber. After being made into soluble cellulose xanthate by processes such as alkalization, aging, and sulfonation, it is dissolved in viscose composed of dilute lye and spun into regenerated cellulose fiber by wet spinning with viscose as the spinning dope. Viscose fiber has advantages such as strong hygroscopicity, air permeability, comfortable wearing feeling, smoothness and coolness, antistatic property, easy dyeing, and good spinnability, and is widely used in fields such as clothing, household fibers, and non-woven fabrics.

[0003] Viscose macro biofiber, that is, macro-functional viscose fiber, is processed by a special technology in which a certain amount of functional substances acting on the human body and other organisms is added to the polymer of viscose polymer to endow the viscose fiber with one or more functions. In recent years, varieties of bio-functional fibers at home and abroad have continuously introduced new ones to provide more space for the development of functional products. The consumption of its market is also growing larger and larger, and it has a broad range of application prospects in fields such as construction, transportation, water conservancy, agriculture, fishery, medical treatment, and even electronic equipment, communication, and national defense. Therefore, functional viscose fiber is the focus of future development in the field of functional fiber materials with the characteristics of viscose fiber, its specialty, differentiation, and functionality, attracting industry attention and market welcome.

[0004] The antioxidant properties of viscose macrobiofibers can be improved by adding antioxidant active ingredients, and among these, plant-derived antioxidant active ingredients are popular among users due to their superior environmental performance. Sources of plant-derived antioxidant active ingredients mainly include tea, peppermint, lavender, tomato, orange, yucca, Japanese knotweed, and grapes.

[0005] Prior art has mainly involved two improvements to enhance the antioxidant performance of viscose macrobio fibers. One method involves mixing the active ingredient into the spinning solution and spinning it directly. However, if the volume of the active ingredient is small, it can be completely encapsulated in the spinning solution, making it difficult to release and limiting its effectiveness. The other method involves spinning the fibers first and then attaching the active ingredient to the outside of the fibers. While fibers produced in this way have good active ingredient release performance, the active ingredient tends to peel off after washing, resulting in a low wash-resistant effect.

[0006] This invention proposes a viscose macrobio fiber containing an antioxidant active component and a method for preparing the same, in order to develop a viscose macrobio fiber with good antioxidant effect and excellent washability. [Overview of the project]

Step 2, Preparation of spinning solution: Thoroughly mix the modified COFs and the spinning solution to obtain the spinning solution. Step 3, Spinning: A spinning solution is used to perform the spinning process and prepare viscose macrobio fibers containing antioxidant active ingredients.

[0015] Preferably, in step 3, the spinning solution is introduced into the spinning machine, the spinning process is carried out at a spinning speed of 15 to 18 m / min, the spun fibers are passed through a solidification bath at a temperature of 30 to 35°C, and after solidification, desulfurization, washing, oiling, and drying are performed to prepare viscose macrobio fibers containing antioxidant active components.
