Embodiment 1

[0016] A medical spandex strap is woven from modified spandex fiber and bamboo fiber at a mass ratio of 5:2.

[0017] Further, the preparation method of the modified spandex fiber is:

[0018] Soak the spandex fiber in sodium hydroxide solution at 50°C for 20 minutes, then ultrasonically treat it for 1 minute, then filter it, wash it with deionized water, dry it to constant weight, and then place the spandex fiber in a vacuum reactor under the protection of an inert gas atmosphere , then continuously feed the mixed gas of dichloromethane and isocyanate at 70°C, the reaction time is 3 hours, then continue to feed water vapor, continue to keep warm for 1 hour, then take it out, put it into the coupling agent solution for 30 minutes, and then filter , washed with deionized water, and dried to constant weight.

[0019] Further, the pH of the sodium hydroxide solution is 10.

[0020] Further, the ultrasonic frequency is 30kHz, and the power is 700W.

[0021] Further, the inert g...

Embodiment 2

[0026] A medical spandex strap is woven from modified spandex fibers and bamboo fibers in a mass ratio of 5:3.

Abstract

The invention discloses a medical spandex strap, and relates to the technical field of medical straps. The strap is woven by modified spandex fibers and bamboo fibers in a mass ratio of 5:2-3; the medical spandex strap has excellent tensile strength, which is more than 30% higher than that of a strap of the same specification made of the pure spandex fibers.

Description

technical field [0001] The invention belongs to the technical field of medical straps, in particular to a medical spandex strap. Background technique [0002] Bandages are gauze bandages that bind wounds or affected areas. They are common medical supplies. There are many different types and methods of dressing. It is necessary to choose the appropriate type and method of dressing according to the injured part. There are many kinds of medical bandages, which include: 100% cotton plain weave, wrinkled elastic bandages, polyurethane elastic bandages, PBT elastic bandages, cotton gauze selvage bandages, viscose plaster bandages. The existing spandex straps have general performance and are easy to break. Contents of the invention [0003] The object of the present invention is to provide a medical spandex bandage aiming at the existing problems. [0004] The present invention is achieved through the following technical solutions: [0005] A medical spandex strap is woven fro...
