Under the ban on plastics, meltblown non-woven fabrics have entered the era of degradability!

In today's world, green development has become an important trend. The concept of green development is deeply rooted in the hearts of the people, and green development will become an important starting point for sustainable development and economic structural transformation. After years of green innovation and development, the non-woven industry has continued to promote the transformation and upgrading of the textile industry, and has gradually become an important force for the continuous improvement of China's industrial textile industry and even the entire textile industry.

At present, the ecological environment and economic environment are undergoing profound changes. Green development, green products, and low-carbon environmental protection have become important issues in industrial development. In the context of global green production and responsible consumption, the nonwovens industry is facing higher requirements from regulators, environmental protection organizations, supply chains and consumers. Green development has become the top priority of the future development of the industry.

Realizing the green development of the non-woven industry is not only an urgent requirement of the world, but also an inevitable choice for my country's economic and social development, and it is also the key to the sustainable development of the industry; to realize the green development of the non-woven industry is to create value, focus on the long-term, and integrate into the international market. It is a major event that has a foothold and a dominant position in it; realizing the green development of the non-woven industry is an important way to promote consumption upgrades, and an important link to promote consumer preferences for technology, green and product functional attributes; The green development of the industry is an important means for the industry to break through the international green trade barriers and enhance the competitiveness of the entire industry.

As far as the research and development of nonwoven products is concerned, the nonwoven technology of polymer direct-forming method has been continuously developed and widely used in many industrial and civil fields due to its simple process and short production process, especially by spunbond and meltblown nonwovens. The protective properties of woven materials have been proven in special periods, so their demand has increased sharply. However, nearly 90% of polymer direct-laid nonwovens are currently made of polypropylene (PP), and some are made of polyester (PET), which are derived from natural petroleum and are non-renewable. resources, and cannot be degraded in the natural environment, so its waste disposal has caused many environmental problems. Waste of PP polymer direct-laid nonwovens is also included in this category.

Driven by the new crown pneumonia epidemic, the market demand for spunbond and meltblown nonwoven materials for masks and protection has surged, and the disposal of PP spunbond and meltblown nonwoven material waste has also been put on the agenda. Due to its 100% complete biodegradability and excellent biocompatibility, PLA has successfully become a new generation of "green" fibers in the 21st century. In order to protect the environment and save resources, polymer direct-forming nonwovens also urgently need green raw materials. Among many biodegradable materials, PLA has undoubtedly become the preferred raw material for preparing biodegradable nonwovens. Domestic and foreign industry companies have accelerated the process of improving the performance of PLA spunbond and meltblown nonwovens.

As far as the application of nonwoven products is concerned, with the technological progress and equipment improvement in recent years, the energy structure adjustment, the energy consumption of spunlace nonwovens has dropped significantly. With the advancement of spunmelt technology and the improvement of drafting equipment, the modification of raw materials, the energy consumption of spunbond and meltblown nonwovens has also dropped significantly. The technical standards for energy consumption in the production of spunbond meltblown nonwovens, covering raw materials such as polyester, polypropylene, PLA, nylon, polyethylene or other synthetic fibers, and formulating relevant energy consumption limits for nonwovens per unit product based on the above process technologies energy consumption parameters.
