Cellulosic fiber containing kendir and preparation method thereof

Abstract

The invention provides a cellulosic fiber containing kendir. The fiber comprises 10 to 10.3% of modified functional component (composite particles) and 3.2 to 3.6% of silicic acid colloid. The invention also provides a preparation method of the cellulosic fiber. The preparation method comprises the following steps: preparing the modified functional component (composite particles), preparing silicic acid colloid, blending two components, and carrying out spinning and moulding. The fiber is modified by modified functional component (composite particles) accounting for 10-10.3% and silicic acid colloid accounting for 3.2-3.6%, thus the loss of functional extract is reduced, the decomposition of functional extract caused by strong acid and alkali is reduced; isatis root, sarcandra glabra, and kendir extract in the cellulosic fiber are combined to effectively resist influenza A virus and influenza B virus, and furthermore, the cellulosic fiber can also inhibit staphylococcus aureus, candida albicans, and typhoid bacillus effectively.

Description

technical field [0001] The invention relates to cellulose fiber containing apocynum and a preparation method thereof, belonging to the technical field of textiles. Background technique [0002] The development of functional fibers is a symbol of the progress of modern fiber science. The development of functional fibers, differential fibers and high-performance fibers has created favorable conditions for the technological innovation of the traditional textile industry and the transformation to high-tech industries, and has contributed to the improvement of human living standards. Functional fiber refers to a new type of fiber that has some special function in addition to the physical and mechanical properties of ordinary fibers. [0003] The Chinese patent application number 201210454096.X discloses a viscose fiber containing a natural antibacterial agent and its preparation method. In this patent, the extract of Folium Folium is added as an antibacterial agent to the viscos...

AI Technical Summary

Problems solved by technology

[0007] (1) Adding the functional components of apocynum to the spinning solution directly or as a solution will inevitably lead to the loss of effective substances of plant components due to problems such as strong acid, strong alkali, and high temperature, which will not only affect the quality of the product, but also affect the quality of the product. cause a great waste of resources;

[0008] (2) In the prior art, the functional components of apocynum and the spinning stock solution are generally blended, and then sprayed into the coagulation bath for spinning, because the distribution of the functional components of apocynum in the fiber is random, that is to say, a large amount of The functional components will be distributed in the core layer of the fiber, and the ones distributed on the surface of the fiber or the cortex are less; therefore, a large number of functional components are distributed inside the fiber core layer, which not only cannot exert its functional effect, but also causes a lot of waste of functional components, and also will increase production costs;

[0009] (3) The functional components on the fiber surface will also be lost during washing and friction, thereby reducing the functional effect of the fiber
