Cellulose fiber for non-woven fabric and preparation method

The invention relates to the technical field of preparation of special fibers for non-woven fabrics, in particular to cellulose fibers for non-woven fabrics and a preparation method. Comprising the following steps: preparing a viscose stock solution from pulp, preparing a spinning stock solution, spinning, and post-processing nascent fiber bundles. A turmeric pigment solution is added in the step of preparing the spinning solution, or the turmeric pigment solution is added in the step of post-processing the nascent fiber bundle. By adding the turmeric pigment, the obtained fiber presents a natural color, and has the advantages of cleanness, no fluorescence, low residual sulfur, environmental protection and bacteriostasis; a bleaching step is omitted, so that the problems of chronic toxicity, environmental pollution and the like caused by bleaching are avoided. The cellulose fiber can be widely applied to fibers in the non-woven field, and can meet the product requirements of national standards or related indu
