AI Technical Summary
Technical Problem
Existing medical tapes lose their stickiness during initial bonding due to the influence of water, oil or dandruff on the skin surface, making them unusable. In addition, industrial-grade glue cannot meet the biocompatibility requirements in the medical field, resulting in a waste of resources.
Method used
The staple yarn or network yarn made from short fibers is used as the raw material of the fiber structure layer. The twist and void ratio of the fibers are controlled, and combined with specific chemical treatment and gluing process to form a high-viscosity tape with multiple bonding.
Benefits of technology
The tape maintains high adhesive performance during multiple uses, reduces resource waste, and meets the biocompatibility requirements in the medical field.

Abstract
The invention relates to the technical field of medical materials, and particularly discloses a high-viscosity adhesive tape capable of being bonded repeatedly and a preparation method of the high-viscosity adhesive tape. A high-viscosity adhesive tape capable of being bonded repeatedly comprises a fiber structure layer and an adhesive layer arranged on the fiber structure layer, raw materials of the fiber structure layer comprise short fiber yarn or interlaced yarn made of short fibers, the twist degree of the short fiber yarn is smaller than or equal to 200 twists per meter, the short fiber yarn is of a curled or spiral structure, and the adhesive layer is arranged on the fiber structure layer. The void ratio among fibers in the staple fiber yarns is greater than or equal to 30%; and the distance between connecting points among fibers in the interlaced yarn is greater than or equal to 2mm. When the adhesive tape is extruded by an external force, the fibers can drive the glue to correspondingly change to form a new glue surface, so that the adhesive tape has better bonding performance, and the adhesive tape can be used for multiple times.
