Problems solved by technology

[0002] Wigs are known as "fashion on the head". As a high value-added product, it has broad market development space at home and abroad. However, the current wig products on the market have performance defects, such as flame retardancy that cannot meet the requirements. , easy to cause secondary burns, and consumers prefer wigs with real hair simulation properties, such as skin-friendly, hot dyeing, curling, etc.
Due to the disadvantages of high energy consumption and high pollution in the production of wigs made of chemical fibers, the search for new green and degradable wig raw materials has become a research hotspot

Abstract

The invention relates to a preparation method of a composite fiber for a wig, and particularly relates to a preparation method of a composite fiber for a high-intensity seaweed / euphausiid protein simulation wig. The preparation method comprises the following step: adding a composite enhancer in the preparation process of a spinning solution, wherein the composite enhancer comprises the following components in percentage by weight: 70-90% of micromolecule dialdehyde and 10-30% of a hydrochloric acid and acetic acid mixture, wherein the volume ratio of hydrochloric acid to acetic acid in the mixture is (1 to 1) to (1 to 3). According to the method, natural environment-friendly degradable sodium alga acid and euphausia superb protein are compounded organically so as to prepare the simulation wig similar to real hairs in performance; the enhancer is added into the raw materials for improving the mechanical intensity of composite fibers; according to different thresholds of the added enhancer, the mechanical intensity can be improved by 1-7%.
