Experts believe that under the current monopoly of fiber-grade polylactic acid chips and production technology in foreign countries, the results have self-designed and built a 50-ton/year polylactic acid continuous bulk polymerization, direct spinning filament device with a thin film reactor as the core. The first “one-step spinning†new process not only fills the gaps in the domestic market, but also shortens the technological process, reduces the melt decompression, and reduces the production costs compared to the “sliced ​​spinning†technology used in the United States and Japan. It ensures the quality of fiber and enhances China's competitiveness in the international polylactic acid market. This is of great significance for promoting the industrialization of polylactic acid resin and fiber in China, prolonging the industrial chain of corn, and promoting the major changes in the textile and clothing industry, and it contains enormous business opportunities.
This technology is called continuously polymerized melt direct spinning polylactic acid filaments, which is abbreviated as "one-step spinning." Polylactic acid filament is a new type of polymer fiber material obtained from corn starch as a raw material, using bacterial fermentation and chemical synthesis methods. It can be fully biodegradable, technical indicators reach the level of similar products in the United States, physical properties and commercial polyester and nylon length There is no difference in silk.
It is understood that Jing Qibin, researcher of Changchun Yinghua Institute of the Chinese Academy of Sciences and his research team have cooperated with Changshu Changjiang Chemical Fibre Co., Ltd., which is a powerful company in the chemical fiber industry in China, and organized the continuous polymer melt direct spinning polylactic acid fiber technology from 2006. "Study with the technology", and in November 2006, firstly spinning a polylactic acid filament on a model device. Based on this, they independently developed a continuous polymerization direct spinning device with a production capacity of 50 tons per year and a thin film reactor as the core. In November 2007, they succeeded in spinning polylactic acid filaments at a spinning speed of 2800-5000 m/min. Tests and dyeing tests conducted by the Jiangsu Provincial Fiber Inspection Institute have proved that the polylactic acid filaments are comparable to commercially available filaments such as polyester and nylon, and the main technical specifications are the same as those of US sliced ​​and spun polylactic acid fibers.
The next step of the project will be transferred to an expanded test of 500 tons/year. While stabilizing the production quality of polylactic acid filaments, polylactic acid staple fibers and their downstream products will be developed.
Pour your milk into a microwaveâ€safe container and heat for about 45 seconds, or heat it in a saucepan on the stove until just before boiling.
Transfer the milk to your Mellow Bird`s coffee mug.
Place the whisking end of the frother into the milk. It should be just barely under the surface of the milk.
Turn on the frother and move the whisk around the surface of the milk, creating a thick foam on the top.
Turn off the frother when you have created the desired amount of foam. This is usually about ? inch thick on top of the milk.
Rinse the Milk Frother head under warm running water to ensure that all residue is removed. Dry with a dish towel and store for the next use.
Brew your coffee and pour into the mug. Add sugar if desired and enjoy a milder coffee experience.
