The invention relates to the field of dyeing and finishing of bio-based fabrics by bio-based dyes, in particular to a method for dyeing polylactic acid / cotton blended fabrics, which comprises the following steps: mixing visible blue, sodium hydrosulfite, sodium carbonate, caustic soda and water, fully reducing and diluting to obtain visible blue dyeing liquid, adjusting the pH value to be acidic, then mixing with a dispersing agent and an accelerating agent, and uniformly stirring to obtain the polylactic acid / cotton blended fabrics. Immersing the polylactic acid / cotton blended fabric for dyeing treatment, and then performing color development treatment, soaping treatment and color fixation treatment. Aiming at the problem that the polylactic acid / cotton blended fabric is difficult to dye at present, the dyeing method for the polylactic acid / cotton blended fabric is provided, the microbial-sourced ornamental blue is selected as a dye, and the dyeing method has the advantages of being green, environmentally friendly and easy to combine with the polylactic acid / cotton blended fabric; meanwhile, according to the dyeing process, on one hand, the using amount of sodium hydrosulfite is reduced, so that pollution to the environment is reduced, and on the other hand, the dyeing temperature and time are reduced, the energy consumption is reduced, and the dyeing efficiency is improved.

A method for preparing colored radiant cooling wood is disclosed. The purpose of this invention is to solve the application problems of existing microstructured colored radiant coolers, such as difficulty in preparation, high production costs, and lack of environmental friendliness. The preparation method includes: 1. Immersing dried wood in a lignin removal solution under vacuum conditions, followed by a water bath reaction at 75–80°C; 2. Dispersing fluorescent dye in an organic solvent, mixing it with methyl methacrylate monomer, adding the initiator azobisisobutyronitrile (AIBN), and prepolymerizing at 70–90°C; 3. Permeating the delignified wood into a prepolymerized dye / MMA mixed solution under vacuum; 4. Heating and polymerizing at 70–90°C. The delignified wood used in this invention is green and environmentally friendly. While maintaining excellent mechanical strength, the shape and size of the colored radiant cooler can be rationally set according to the needs of different scenarios, taking into account both flexibility and toughness, and is cost-effective.

The invention belongs to the technical field of food fermentation industry, and particularly relates to a yeast composition for improving the fermentation and gas retention capacity of low-sugar dough and preparation and application of the yeast composition. The yeast composition comprises the following components in parts by weight: 420-480 parts of low-sugar active dry yeast, 1-10 parts of amylase, 5-20 parts of an oxidant, 1-5 parts of a stabilizer and 10-80 parts of filler. According to the yeast composition for improving the fermentation gas-retaining capacity of the low-sugar dough, the gas-retaining capacity of the low-sugar dough in the fermentation process is improved, the dryness and smoothness of the low-sugar dough are improved, the stability of the low-sugar dough is improved, meanwhile, the size of a low-sugar bread finished product obtained after the low-sugar dough is baked is increased, and the taste of the low-sugar bread finished product is improved. And the coloring effect of the low-sugar bread finished product is improved.

This invention provides a hair dyeing device based on an immersion mechanism, comprising a dyeing section, a liquid storage section, and a pumping section. The pumping section pumps the hair dye paste from the liquid storage section to the dyeing section. The dyeing section includes a front outer shell and a front upper cover arranged in a relatively open and closed manner. The front end of the front outer shell has a discharge structure communicating with the liquid storage section. A vibration mechanism is installed inside the immersion chamber. The discharge structure forms an immersion chamber with the front upper cover. During hair dyeing, the hair section is located in the immersion chamber and comes into contact with the hair dye paste inside. The vibration mechanism immerses the hair section in the hair dye paste through vibration. This invention, by forming an immersion chamber in the dyeing section, ensures that the hair section is completely enveloped and immersed in the hair dye paste. Simultaneously, the built-in vibration mechanism drives the hair dye paste to fully mix and contact with the hair section, effectively avoiding the problem of uneven distribution of hair dye paste among the hair strands, significantly improving color uniformity and coloring effect, and enabling scientific control of the amount of hair dye paste used, avoiding waste.
