Recently, the first domestic post-processing complete set of “single-line annual output of 60,000 tons of new solvent-based cellulose fiber” independently developed by Hengtian Heavy Industry was successfully launched at the user’s factory. The complete set of equipment includes a refining combined machine and a dryer The combined machine is a complete set of post-processing equipment specially developed by Hengtian Heavy Industry based on the characteristics of lyocell fiber.
As a textile machinery manufacturing enterprise specializing in the production of chemical fiber equipment, Hengtian Heavy Industry has never been absent from the research and development of new fiber equipment. As early as 2004, it provided the refining combined machine, drying combined machine and solvent recovery device for the Shanghai Leo project, the first lyocell fiber test line in China.
After years of research and development, Hengtian Heavy Industry has developed a complete set of post-processing equipment with completely independent intellectual property rights specifically for the production of lyocell fiber based on the production process characteristics of lyocell fiber. The refining machine is equipped with a special structural capillary pipe, fiber feeding trough and high-pressure rolling car with multiple patented technologies to ensure the fiber opening, leaching effect and moisture regain; the drying machine uses hot air to penetrate the lyocell fiber The resistance characteristics of the fiber were experimentally determined and the thermal calculation was performed to ensure the uniformity of the hot air in the width direction of the dryer and good sealing.
Since 2010, Hengtian Heavy Industry has provided post-processing for lyocell fiber production lines with an annual output of 0.5 to 60,000 tons for more than ten projects including Baoding Swan, Shandong Yingli, and China Textile Research Institute. A set of equipment. Among all lyocell fiber projects in China, Hengtian Heavy Industry’s complete set of post-processing equipment has a market share of more than 90%. In addition, the lyocell fiber complete equipment developed by Hengtian Heavy Industry covering the entire process of dope, spinning and post-processing has also been successfully launched on the market and put into production and application by many users.
