At the same time, seamless transportation has functions, such as: supporting breasts, tightening waist, lifting hips, etc. It can make the neck, waist, buttocks and other parts that have more friction in daily life without seams and avoid the discomfort of wearing.
There are many methods for manufacturing seamless underwear. The most famous and world-leading Italian Santoni seamless knitting machine uses a high-tech special equipment to combine seamless weaving and production of high-elastic knitted underwear and high-elastic sportswear. However, due to the huge investment, a large number of small and medium-sized underwear processing companies are shut out. The hot-melt dispensing and laser cutting integrated machine developed by Dongguan Hengde Optoelectronic Equipment Manufacturing Co., Ltd. provides a set of points for many small and medium-sized underwear processing companies. The integrated solution of glue and laser cutting has low investment threshold, mature technology, simple operation, easy to learn and understand. It is of great significance for the majority of small and medium-sized underwear processing enterprises to improve product quality, enrich products and improve market competitiveness. This equipment has participated in this year's Munich Laser Expo in Germany and has received unanimous praise from Chinese and foreign customers.
The working principle of non-contact PUR jet dispensing and laser cutting
The core sewing technology of seamless underwear is to use a non-contact, high-speed and high-frequency dispensing technology to glue the edges that originally need to be sewn without using traditional sewing machines and other sewing equipment. Two or more parts are glued together through hot pressing. Connected together, (the consistency accuracy of the sprayed glue points is more than 98%, the maximum frequency is 200Hz, the minimum injection volume is 0.2nL, the minimum focus diameter is 0.3mm, the minimum nozzle is 0.15mm, and the minimum line width of the injection is 0.35mm, at the same pressure and temperature down, the dispensing accuracy can reach 2%,).
The model iC7050RF30C "PUR hot melt dispensing laser cutting all-in-one machine provided by DUANGUAN EVER TECH LASER TECHNOLOGY LTD. is based on the principle of importing the layout chart that needs to be bonded into the random ETL-Cutting software control system in the computer (computer) , one-click startup, the equipment automatically completes dispensing and automatic laser cutting along the dispensing edge. The maximum working area of the system is 700*500mm (the factory accepts customization). It can be equipped with automatic feeding, automatic feeding and placing, manual sorting table and hot stamping. system.
