After break through of traditional concept of joining cutting pieces with needle and sewing thread, creative development of high-strength environmental-friendly adhering material of new type and successful research of manufacturing technique of seamless adhering, seamless pure cotton shirt is first created and a new leap from seam shirt to seamless shirt is realized, a technical revolution in the world's closing history.
Luthai with Hong Kong Polytechnic University has developed low torque yarning technique, or Nu-Torque yarning technique, with application of which yarns have features of low torque, low twist and high strength, finished fabrics have features of softness. Moreover, advantages of higher production capacity and pollution free in the whole process are showed.
The promotion and application of Nu-Torque yarning technique not only improves the quality and grade of fabric but also produces the new trend of “scientific fabric” in international high-grade fabric industry. Industrial application of Nu-torque yarning technique in producing pure cotton high count yarn has been realized.
Luthai has joined hands with Jiangnan University and Wuhan Textile University to make extensive research on the yarn structure and its surface properties, performance of sizing agents and their compatibility, sizing techniques and parameters of supportive facilities and other aspects. Industrial application of foam sizing technique is finally realized which will greatly reduce the consumption of sizing agents. Great achievements have been made in research and application of degradation of desizing agents.
Luthai has developed high flux membrane treatment and reuse technology of dyeing water with the cooperation with Donghua University and has build up a modern wastewater treatment plant with a daily processing capacity of 80,000 tons. Top technologies of Orbal oxidation ditch of Germany and high-sludge sedimentation tank of France have been adopted. The water quality after treatment reaches standard A of the first class and wastewater reuse rate is up to 40%. Moreover, segregation of high and low concentration wastewater in early stage, recollection in medium stage and further treatment in later stage have been realized which pushes forward the development of wastewater reuse technology in China.
Considering the disadvantages of traditional dyeing process – large energy consumption, high cost, low output that are against sustainable development, Luthai has put forward overturning concept – “jigger dyeing” based on the existing equipment performance. This technology breaks the traditional method of full immersion. Luthai is the first to successfully develop “jigger dyeing” technology of international leading level in the industry based on creative transformation of dyeing equipment and research on dyeing parameters, bring about remarkable energy saving effect.
