"The Role of Engineering Companies in the Development of Intelligent Manufacturing"

Intelligent manufacturing is a new generation of industrial revolution driven by personalized customer needs and led by new technologies. Its common feature is the digitization of automation equipment, whose core is automation and digitalization. In other words, it has become an inevitable trend to replace the person with intelligent equipment to complete the monotonic mode operation. Similarly, simple data analysis has been difficult to meet actual needs, but rely on big data technology and systems to support corporate management decisions. As the “technical responsibility” of the textile industry, the non-woven industry needs to realize intelligent manufacturing.

"Application of Nanotechnology in the Nonwovens Industry"

Nanotechnology is a science and technology that uses a single atom or molecule to make a substance. Nanotechnology has a wide range of applications in the non-woven industry. Different nanomaterials can achieve different functions. For example, nano-modified fibers can be used for photocatalysis, antibacterial and antistatic. Nano-woven fabrics can be used to prepare filter masks, carbon nanotubes and other materials. . However, due to technical limitations, domestic electrospinning nanotechnology is still in the scientific research stage and has not reached the mass production capacity. According to market demand, the future development direction of this technology will focus on the development of functional masterbatch, nano-material functional finishing, nano-nonwoven material preparation and application, electrospinning nanofiber-nonwoven composite film development, nano-carbon material flexible sensor development. 5 aspects.

"Research Status and Development of Nonwovens Technology for Preparation of Cellulose Solution"

Cellulose fiber has excellent properties such as good skin contact, wearing comfort, physiological safety, moisture absorption, easy finishing, and biodegradability. At present, there are advanced technologies such as wet melt-blown wet spunbond and Lyocell melt/meltblown preparation technology. Therefore, non-woven fabrics made from cellulose fibers are used in medical, nursing, sanitary products, cosmetics, industrial fields, and agriculture. Broad use. However, there are also some problems in the cellulose solution nonwoven technology, such as in the special equipment, technology and application development. For this reason, cooperation and synergy between the future technology, special equipment development, product development and market application should be mutually affected. And promote, jointly develop new products and broaden market applications.

"Development Status and Future Application of Meltblown Process Technology and Products"

The current status of meltblown nonwovens, focusing on the market of meltblown filter products and meltblown car sound absorbing cotton, and pointed out the future development trend of the meltblown industry. He pointed out that there are about 70 large-scale melt-blown nonwovens manufacturers in the country with a total capacity of more than 80,000 tons. In the future, the melt-blown industry advocates the concept of “meltblown+” product development. The multiple variability of the melt-blown process can produce non-woven fabrics suitable for various purposes. This is incomparable to the spunbond process and is also a melt-blown process. Particularity. According to this idea, we can add other nano-scale raw materials (raw material +) to the PP raw material, or mix different fiber materials (spinning +) in the PP spinning process, so that it can be developed according to different application fields. Different products.

"Nonwoven Plant Green Factory Design and Case Analysis"

He proposed the concept of a green factory for nonwovens and looked ahead to it. He pointed out that the industrial green development plan (2016~2020), "Made in China 2025", and "13th Five-Year Development Guidance for Industrial Textiles Industry" all mentioned the concept of green manufacturing, which is also the background of the green factory. The green factory design mainly includes three aspects of green products, green crafts and green buildings. The green factory of non-woven fabrics also needs to start from these three aspects. Therefore, in the future, BIM (BuildingInformationModeling) technology will be incorporated into the design of the nonwoven plant to create a virtual building model; computer simulation will assist the green building design, except for conventional wind environment simulation, energy simulation and noise simulation, air conditioning system optimization simulation, etc.; The light pipe is used for natural lighting; the capillary three-dimensional radiant heating and cooling system is used; and the humidity independent air conditioning control system is adopted, thereby realizing green manufacturing.
