This invention relates to a blending process for hemp fiber and sorona fiber, belonging to the technical field of blending and processing of natural fibers and bio-based elastic fibers. The blending process for hemp fiber and sorona fiber of this invention includes the following steps: raw material selection → pre-spinning process → post-spinning process → packaging. This invention solves the problems of poor spinnability, high breakage rate, and stiffness and wrinkling in pure wet-spun hemp through specific proportions and wet spinning processes, achieving high-count, stable, and high-quality production. This significantly improves spinnability, enhances yarn quality, and greatly improves hand feel and comfort, achieving high elasticity and comfort to meet user needs.

The application discloses a kind of embroidery methods based on color separation proportion mixing silkworm silk thread to realize gradual change color effect, it is characterized in that: embroidery thread is composed of multiple same hue or multiple different hue silk threads, wherein, each strand is several silk threads of same hue but different lightness, and is formed by mixing and parallel or slightly twisting according to predetermined lightness proportion, and the silk threads of same hue in each strand are divided into dark, intermediate color, light, highlight color according to different lightness from dark to light.The embroidery method is to divide the entire embroidery pattern into three embroidery layers to be embroidered in sequence, i.e., bottom layer, middle layer and upper layer, and different predetermined lightness proportion silk threads are used for each layer.The application utilizes the characteristic of silkworm silk thread with luster, under the action of natural law of light reflection, combined with multi-color combination and different lightness proportion change of color in different embroidery layers, thereby solving the problem that there is no suitable gradual change color embroidery effect in the field of Suzhou embroidery for a long time.

The invention provides a preparation method of modified stropharia rugosoannulata crude polysaccharide and application of the modified stropharia rugosoannulata crude polysaccharide in lactobacillus fermentation of rhizoma polygonati, and belongs to the technical field of bioengineering. The method comprises the following steps: carrying out irradiation treatment on crude stropharia rugoso-annulata polysaccharide, and then carrying out ultrahigh pressure treatment to obtain the modified crude stropharia rugoso-annulata polysaccharide. In order to solve the problem that the proliferation of lactic acid bacteria is inhibited in the fermentation process of rhizoma polygonati, the growth of the lactic acid bacteria is promoted by adding the modified stropharia rugoso-annulata crude polysaccharide. The method can effectively reduce the inhibition effect of the polygonatum sibiricum primary pulp on lactic acid bacteria and improve the fermentation efficiency. After the fermentation broth is applied to polygonatum sibiricum fermentation, the content of irritant components is reduced, the taste and flavor of primary pulp are improved, the content of saponins, total phenols and total flavonoids is remarkably increased, and meanwhile the content of cholesterol is reduced. In addition, the inhibition capability and the antioxidant activity of the fermented polygonatum sibiricum primary pulp on alpha-glucosidase are enhanced, and the comprehensive quality of the product is remarkably improved.
