& nbsp; Honeycomb core (honeycomb structure absorber) is a new type of absorber created by Dawang paper after 40 years of experience in baby diapers. At present, two invention patents of the research have been authorized by the State Intellectual Property Office (patent numbers: zl201711431157. X, zl201780017373.1). It is now used in goo launched in 2020 N big Wang Guangyu gilt series baby diapers.
& nbsp; Its hexagonal structure like a honeycomb is bonded by ultrasonic waves of different intensities to realize the product characteristics of fast absorption, high air permeability and high strength. Combining the advantages of mixed core and composite core, we can achieve the best of both worlds.
& nbsp; Ultrasonic bonding technology is used to bond the absorber, reduce the use of hot melt adhesive, and form a good ventilation channel at the embossing to achieve high air permeability
& nbsp; In order to make SAP have enough space after water absorption and expansion and give full play to its absorption force, each hexagon point and line is slightly bonded with ultrasonic technology to improve SAP's absorption of urine.
