    2014/12/17 7:47:00 36

    Low Carbon Water SavingDenim YarnClean Dyeing.

      

    Zhen Hua Luo

    Over the years, he has devoted himself to the research of the new technology and principle of jeans dyeing. He is the technical director of the project. He is mainly responsible for the research and development of the technology of denim yarn, reactive dyestuff, wet short steaming, dyeing and finishing, cleaning and dyeing equipment, digital on-line detection and control integration technology, digital online collection system key technology research and development, modified liquid adding control technology, dyeing tank level balance replenishment technology research and development, and the research and development of the antique style high-end colorful cowboy series products.

    Main innovation points of the project

    One

    Denim yarn

    Paint,

    Technology of reactive dye wet short steamed yarn

    The process is short and the salt free dyeing is achieved. Compared with the traditional denim yarn dyeing technology, the water saving is 85% and the energy saving is more than 30%, which basically realizes zero discharge of waste water. The precise control of the temperature and humidity and the salt free dyeing of the denim yarn production process enrich the flower color products of the cowboy products.

    2. independent research and development of clean dyeing equipment, digital online detection and control integration technology, digital online collection system key technology, to achieve precise temperature and humidity control technology in denim yarn production process, adding control technology of modified liquid, and water balance technology of dyeing tank.

    3. development and preparation technology of unique modifiers, environment-friendly adhesives.

    4. the dye is circularly distributed on the cross section of the yarn to meet the market's demand for the antique style colorful denim series products.

    The project has built 1 clean and dyed yarn production lines for denim yarn. Through the implementation of this project, it can promote the synchronous development of the related textile printing and dyeing enterprises in China, and it has a positive and positive effect on the implementation of energy saving, environmental protection and cleaner production technology in the printing and dyeing industry.

    In 2013, the sale of clean dyed denim fabrics was 7 million 200 thousand meters, with an additional profit of 11 million 730 thousand yuan and a tax of 5 million 570 thousand yuan.

    Li Zi army has long been engaged in the development and innovation of new shuttleless looms, such as rapier, jet, towels and water sprayed.

    It has hosted more than 30 new products of shuttleless looms.

    The head of the project is responsible for the overall technical design of the project and the development of core technologies such as electronic loop.

    Main innovation points of the project

    1. develop a reed high grade towel loom with electronic loop function.

    The combination of the electronic loop mechanism and the electronic control system can realize the arbitrary switching of the 3~7 weft ring. The height of the terry can be set freely, and the automatic speed change can be used to weave the high-grade Terry tissue such as wavy hair, convex concave hair and so on.

    2. R & D reed ring connecting rod mechanism, kinematics and dynamics analysis of reed movable ring connecting rod mechanism, optimization design of "trapezoidal acceleration electronic cam" motion curve, careful analysis and optimization of materials, not only to ensure high strength, high wear resistance, but also reduce the material weight, meet the speed and accuracy of the mechanism and stability.

    RFTL60 high-speed towel rapier loom has sold more than 1300 units.

    It has been sold in bulk to Zhejiang, Hebei, Sichuan and other places.

    In the past three years, the total sales revenue increased by 466 million 100 thousand yuan, with a profit of 53 million 455 thousand yuan, a profit of 17 million 818 thousand yuan and a foreign exchange earning 27 million 649 thousand yuan.
