"Research and development of sanitary hot air non-woven materials" completed the production, research and research project

In order to make consumers, especially infants, more comfortable and smooth when using sanitary products such as diapers, Tianjin University of Technology and Beijing Jinglan Nonwovens Co., Ltd. cooperated in the research and development of sanitary hot air non-woven materials, and The project acceptance was completed on the 25th of the month.

The sanitary topping material needs to contact the user's skin, especially as the surface layer of the baby diaper, and also the baby's delicate skin. Therefore, the surface layer material must be delicate, soft, smooth, and minimize the friction with the skin. Make the user feel comfortable. In addition, it is also required to have high elasticity, support and increase the thickness of the entire cloth surface, and reduce the amount of back-covering of the surface material.

It is understood that the surface layer of sanitary materials currently used is generally hot air or thin spunbonded nonwoven materials. Among them, the hot air non-woven surface layer material has a cotton soft and fluffy touch, while the spunbond non-woven surface layer material has the characteristics of silky softness and smoothness. The flow guiding layer is a layer of non-woven fabric material between the surface layer and the absorbent core layer, which can quickly guide the liquid to flow from the surface layer to the absorbent core layer, and can increase the diffusion range of the liquid, so that the absorption core layer The effective absorption area is increased to prevent the liquid from flowing in a small area to cause gel blocking, effectively avoiding side leakage and back osmosis, and ensuring the dryness and comfort of the surface layer.

Compared with other non-woven fabrics, the thickness of the hot air guiding layer is 3 to 5 times that of the same amount of hot-rolled and spunbonded cloth. It has a good spatial structure, and the gap between the fibers is large, and the quality can be temporarily stored. More than double the liquid, and has excellent anti-leakage performance, is currently the mainstream of the domestic diversion material market.

Tianjin University of Technology and Beijing Jinglan Nonwovens Co., Ltd. jointly developed the “Research and Development of Hygienic Hot Air Nonwoven Materials” project, which was developed through the selection of new fiber materials and hot air process parameters. A smooth, hygienic hot air non-woven facing material with the advantages of hot air and spunbonded nonwovens. At the same time, through the selection of eccentric hollow fiber and optimized hot air process, the hot air non-woven diversion layer material with rapid penetration, low reductive amount and good resilience is developed. The project has very important theoretical significance and practical value for improving the grade of sanitary non-woven products, enriching the variety of sanitary non-woven products, and broadening the application of non-woven materials.

According to industry experts, the overall technology of the project has reached the domestic leading level and has a good market prospect. In the future, the market application and promotion of the technology products should be further promoted. At present, the research results of the industry-university research project have been applied in health products, have independent intellectual property rights , have applied for one invention patent, and have been authorized two utility model patents to help train two graduate students and promote scientific research. The organic combination of technology development, enterprise production and talent cultivation.

Tianjin Polytechnic University

The school's textile discipline was founded in 1912. It has become the most modern textile school in the north of China. It is the first batch of “double-class” universities in the country. It is also the pioneer of textile higher education in China and the leader in the field of industrial textiles . . The Textile College of Tianjin Polytechnic University is an important modern textile talent training and research base in China. It has set up the professional direction of non-woven fabrics in the country and has now developed into a national-level specialty and a Tianjin brand.

In recent years, Tiangong University has undertaken nearly 9000 projects including the “973” plan, the “863” plan, the national key R&D plan project (the project), the National Social Science Fund Project, the National Natural Science Foundation project, and various provincial and ministerial-level scientific research projects. It has won a number of landmark and breakthrough achievements, and has won 13 national science and technology awards and more than 1,000 patents granted. Among them, many scientific research achievements have broken international monopoly and applied to national strategic emerging industries and national defense high-tech industries.

Beijing Jinglan Nonwoven Fabric Co., Ltd.

The company is part of Beijing Fashion Holdings Co., Ltd., founded in 1993, specializing in the development, production and sales of thermal bonded nonwovens. At present, Jinglan is the only wholly-owned state-owned enterprise in the field in China. There are five hot air production lines, and there are perforated ginning and spindle slitting finishing production lines. Two of the production lines are hot air/hot rolling flexible production lines, one of which is a flat net hot air production line with a width of 3200MM. The company's non-woven fabric production capacity has reached more than 6000T.

The company mainly produces hot-rolled and hot-air non-woven fabrics suitable for sanitary napkins, diapers and wet wipes. The varieties cover: perforated ginning hot air non-woven fabric, hot air super soft surface layer, super soft whitening hot air surface layer, hot air non-woven Woven cloth, white flow guiding layer, color guiding layer nonwoven fabric, hot rolled viscose -containing nonwoven fabric.

Jinglan Company pays attention to independent innovation, protects intellectual property rights and enhances product development capability. In 2003, the company's management system has made a qualitative leap through the quality, environment and occupational health and safety management system. A non-woven fabric company that has received this award. In 2017, Jinglan Company established a cooperative relationship with Tianjin University of Technology, and reached cooperation in product research and development, technical consultation and service, and personnel training. In 2018, Beijing Jinglan Nonwovens Co., Ltd., Guangshan White Shark Clothing Co., Ltd. and Tianjin Polytechnic University established a carding technology research station, integrated technical resources in the domestic combing field, and built a platform for scientific research, technology and other collaborative research, and carried out forward-looking Carding technology research. In 2017, Jinglan Company completed the identification of Zhongguancun High-tech Enterprise and won the honorary title of “Zhongguancun High-tech Enterprise”. In 2018, it moved to the national high-tech enterprise.
