Protein fiber micro-suspension energy-saving and environmentally-friendly dyeing technology is suitable for the dyeing of protein fiber (including wool, cashmere, silk, soy protein fiber and yak wool) by hair reactive dyes, acid dyes, neutral dyes and acid complex dyes.
The core of the technology is to use the self-developed micro-suspension auxiliaries in the dyeing process to significantly enhance the adsorption capacity of the micro-suspended dye particles on the fibers, so that the dyeing time is greatly shortened and the amount of waste dyes is significantly reduced. To achieve the goal of energy saving and environmental protection.
The project is a project of “environmental dyeing technology and development of nano-composite dyeable functional fiber†(“10th Five-Year Science and Technology Research Project†has been accepted) and “Dyeing and Finishing Technology and New Soybean Protein Fiber Processing Technology Research†project ( The in-depth and continuation of the national “10th Five-Year Plan for Science and Technologyâ€.
The technical achievements were recognized by the expert appraisal committee as “with independent innovation and at the international leading levelâ€. In addition, this technology has been listed as a key new technology by the National Development and Reform Commission, the Ministry of Science and Technology and the Ministry of Commerce in 2004, the “Priority of the High-tech Industrialization Key Areas of Priority Developmentâ€.
Technical points:
The initial dye bath temperature of the technology can be maintained at 25-35 ° C according to the temperature. No artificial heating is needed. The dissolved micro-suspension auxiliaries are added to the dye bath, and the pH of the dye bath is adjusted to 4.0-4.5. between.
After the dyeing bath is circulated for 2 to 5 minutes, the dissolved dye solution is added to the dyeing bath, and the amount of the dye is in principle consistent with the conventional dyeing process or less than the amount of the conventional dyeing process.
The dye bath is circulated for about 5 minutes. When the amount of dye is less than 1% (owf), it is kept at the above temperature for about 10 minutes to completely absorb the dye.
When the amount of dye is >1% (owf), the dye bath can be heated to 40-60 ° C according to the amount of dye, and the heating rate is about 1.5 ° C / min, so that the dye is completely adsorbed to the fiber.
When the adsorption of the dye to the fiber is completed, the dye bath is rapidly heated at a rate of 3 to 5 ° C / minute. When the dye bath temperature reaches 90 to 95 ° C, the dye is kept for 15 to 40 minutes according to the amount of the dye, and then washed and soaped. After the treatment, the dyeing process is finished.
Economic evaluation:
The industrial dyeing production of protein fiber by micro-suspension energy-saving and environmentally-friendly dyeing technology can shorten the dyeing time by 1/3~1/2, and has remarkable energy-saving effect.
At the same time, the percentage of fixing of the dye is increased by 10% to 30%, and when dyeing the same color depth, the amount of dye can be reduced by about 10%.
According to the above situation, the amount of waste dyes (including waste dyes produced after soaping and washing) in the dyeing residual bath can be reduced by 10% to 30%.
According to the dye bath ratio of 10:1, the waste dye content in the residual bath is ≤0.015% (w/w).
Taking into account the dilution effect produced by the total amount of water discharged during the dyeing process (calculated at 10 times dilution rate), the total content of waste dye in the wastewater discharged from the dyeing process is ≤0.0015% (w/w).
Expert Reviews:
The predecessor of this technology, microcapsule dyeing technology, has been successfully operated in Xinjiang Tianshan Wool Textile Co., Ltd. for 9 years. As an improved protein microsuspension dyeing technology, it has been implemented in Anhui Fuyang Huayuan Wool Textile Co., Ltd. for nearly 1 year.
