Intelligent 3D Adhesive Technology
Over 20 Years Of Research On Scientific And Technological Achievements

Originally used in medical fixation by Germans, it was later applied to the clothing industry; introduced by the Stuttgart R&D Center in Germany.

In 2013, Ascendas International Group introduced the stretch adhesive technology from Germany. Ascendas is the only authorized stretch adhesive product manufacturer in Greater China.

SenElast 3D printing

What is SenElast 3D printing? It is based on a special liquid adhesive, combined with SenElast 3D printing technology, which can perfectly replace traditional materials such as elastic bands, steel rings, and shaping yarns.

Advantages of 3D stretch printing
  1. Possibility of any design
  2. Functional mechanical properties
  3. Super resilience
  4. Wash resistance and fatigue resistance
  5. Applications not limited to any fabric

6 Advantages of 3D Adhesion Technology

Soft support;flexible shaping;super elasticity;Super comfortable;ultra-3D,super safe
Soft support
It can be used on any common fabric.
• Solve the problem of natural fabrics deforming after washing
• Improve the support and plasticity of natural fabrics to address their poor resilience
Soft Shaping
Stretchable surface printing achieves three-dimensional support for the hip curves, showcasing the perfect lines of a woman's buttocks.
• Rebound strength >93.7
• Hip lift 3CM
Super Elastic
It is based on a special liquid adhesive, combined with SensElast 3D printing technology to achieve excellent stretch opening/instant recovery performance.
• No deformation after 2000 stretches
• 100% instant recovery
Super Comfortable
Seamless compression
replaces sewing
flexible and comfortable.
Ultra-3D
3D three-dimensional decorative function (with an embossed texture)
Super Safe
• Medical-grade applications
• Non-toxic and harmless
• Can be used in medical devices
