"The Promoting 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, and its core is automation and digitization. In other words, it has become an inevitable trend to replace humans with intelligent equipment to complete monotonous mode operations. Similarly, simple data analysis has been difficult to meet actual needs, but rely on big data technology and systems to support enterprise management decisions. As the "technical responsibility" of the textile industry, the nonwoven industry especially needs to realize intelligent manufacturing.

"The Application of Nanotechnology in the Nonwoven Industry"
Nanotechnology is a science and technology that uses single atoms and molecules to make matter. The application prospects of nanotechnology in the nonwoven industry are very broad. Different nanomaterials can achieve different functions. For example, nano-modified fibers can be used for photocatalysis, antibacterial, and antistatic, and nanononwovens can be used to prepare filter masks, carbon nanotubes and other materials. . However, due to technical limitations, the domestic electrospinning nanotechnology is still in the scientific research stage and has not reached 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, electrospun nanofiber-nonwoven composite film development, and nano-carbon material flexible sensor development 5 aspects.

"Research Status and Development of Nonwoven Fabric Preparation Technology from Cellulose Solution"
Cellulose fiber has good skin contact, wearing comfort, physiological safety, moisture absorption, easy finishing, biodegradability and other excellent properties. At present, there are advanced technologies such as wet melt blown wet spunbond, Lyocell melt/melt blown preparation technology, etc. Therefore, non-woven fabrics using cellulose fibers as raw materials are used in medical, nursing, sanitary products, cosmetics, industrial and agricultural fields. A wide range of uses. However, there are also some problems in cellulose solution nonwoven technology, such as special equipment, technology and application development. For this reason, future technology, special equipment development, and product development and market applications should form cooperation and synergy, and influence each other. And promote, jointly develop new products and broaden market applications.

"Development of spunlace equipment technology and differentiated products in the new era"
The characteristic of the new generation of upgraded spunlace production line is the wide upgrade, the net width of the product can reach 3300mm; the production capacity upgrade, the speed is 180m/min~200m/min. The application of this high-speed messy new type of netting technology has improved the physical properties of the spunlace cloth. Some products of the direct laying line can replace the semi-cross, which is in line with the mainstream direction of differentiation in the future. It is reported that the energy-saving and high-efficiency 10,000-ton grade spunlace line will be put into production in Changshu next year, and the working width will reach 3.8m.

"Development Status and Future Application of Meltblown Technology and Products"
The current status of meltblown nonwovens, focusing on the market of meltblown filter products and meltblown automotive sound-absorbing cotton, and pointed out the future development trend of the meltblown industry. He pointed out that there are about 70 large-scale meltblown nonwovens production enterprises in the country, with a total production capacity of more than 80,000 tons. In the future, the meltblown industry advocates the "meltblown +" product development concept. The multiple variability of the meltblown process can produce nonwoven products suitable for multiple purposes. This is incomparable to the spunbond process, and it is also a meltblown process. The particularity. According to this idea, we can add other nano-level raw materials (raw material +) to PP raw materials, or mix and add different fiber materials (spinning +) in the PP spinning process, so that we can develop according to different application fields Different products.

"Nonwovens Green Factory Design and Case Analysis"
He proposed the concept of a nonwoven green factory and looked forward to it. He pointed out that the industrial green development plan (2016~2020), "Made in China 2025", and "Thirteenth Five-Year Development Guidance for the Industrial Textile Industry" all mentioned the concept of green manufacturing, which is also the background for proposing green factories. Green factory design mainly includes three aspects: green products, green craftsmanship, and green buildings. The nonwoven green factory should also start from these three aspects. Therefore, in the future, BIM ( Building Information Modeling ) Technology to create virtual building models; computer simulation aids green building design, except for conventional wind environment simulation, energy consumption simulation, noise simulation, and air conditioning system optimization simulation; light pipes are used for natural lighting; capillary three-dimensional radiant heating and cooling systems are used ; Adopt humidity independent air-conditioning control system, etc., so as to better realize green manufacturing.
