On August 14th, the China National Textile and Apparel Council held a technological achievement appraisal meeting for the project "Key Technologies and Industrialization of Bi-Component Spunbond Nonwoven Materials Preparation" in Longkou, Shandong. Leaders and experts from the China National Textile and Apparel Council, CTA, China Nonwovens and Industrial Textile Association, as well as appraisal institutions, higher education institutions, and relevant enterprises attended the event.

According to the information provided, the project was jointly completed by Shandong Dawn SWT Technology Co., Ltd. and Qingdao University. The expert group listened to the project's technical leader's work report and technical presentation on the scientific and technological achievements. After reviewing technical documents, conducting on-site inspections, raising questions and receiving answers, and engaging in rigorous discussions, the expert group unanimously agreed that the overall technology of the project has reached an international advanced level.

The project independently developed a specialized modified bi-component spunbond material that altered the interface polarity, resulting in products with enhanced fluffiness and stability. They also introduced a plate-type melt flexible distribution technology and developed a high-throughput, multi-gradient stretching system, which enabled controlled curling of bi-component fibers during the spinning process. Additionally, they invented a multi-layer composite, fluffy, 3D dimensional, and soft nonwoven fabric molding technology, achieving high-speed and stable production of fine-denier dual-component nonwoven materials.

Only by mastering core technology can we gain the initiative in development. This project holds independent intellectual property rights and has built the first set of 3S flexible bi-component spunbond nonwoven production line in China. It has achieved a combined annual production capacity of 21,000 tons across three lines. The products have wide applications in fields like medical and sanitary supplies, resulting in significant economic and social benefits. "We recommend further market expansion and increased promotional applications," commented the expert group.

Dawn SWT Technology Co.,Ltd located in Dawn New Materials Science and Technology Industrial Park in Longkou City, is recognized as a national high-tech enterprise and a "Gazelle Enterprise" in Shandong Province. The company has expertise in the entire process, formulations, production, and application of nonwoven equipment research and development, manufacturing, and nonwoven fabric technology. They pioneered the production of the first bi-component nonwoven fabric production line in China. With unique development technology and comprehensive solutions for bi-component nonwoven fabric production, the company is dedicated to becoming an expert in "soft nonwoven fabrics."

In the future, Dawn SWT Technology Co. Ltd will leverage the technological advantages of the industrial park and integrate Dawn's unique material modification expertise. They will continue to explore new technologies, applications, and fields while adhering to their business philosophy of "product-based, people-oriented, technology-led, and customer-first." The company plans to research and develop biodegradable nonwoven fabrics using PLA (polylactic acid) and PBS (polybutylene succinate) materials. They will continuously optimize products, extend the product chain, and strive to establish the largest domestic and internationally leading research and production base for bi-component nonwoven fabrics.
