[0002] Traditional elastic bandages use chemical fiber filaments when weaving, or add elastic fibers such as latex filaments or spandex-covered yarns. Chemical fiber filaments have poor moisture absorption and air permeability. Latex filaments are slightly irritating to the skin and can easily cause skin allergies. Moreover, after the traditional bandage is bandaged, it is prone to slipping and loosening, so the user must be cautious about activities or dare not do appropriate exercise, and considering that the bandage is mainly used for treatment and sports, the user sweats a lot. If the sweat cannot be removed in time, there may be unsuitable reactions such as skin itching and rashes. In order to ensure the comfort in use, the bandage must have good air permeability. High requirements are put forward for the gluing process, while the traditional gluing process is mostly a transfer gluing proce...

Embodiment 1

[0018] The viscoelastic elastic biological bandage of the present invention uses semi-combed cotton yarn as a raw material, and zinc oxide is coated on the bandage base cloth. Make the bandage sticky to a certain extent, while retaining the elasticity and resilience of the cotton elastic bandage, so that an appropriate compression force will be generated during use, so as to achieve the therapeutic purpose of helping recovery. Its manufacturing method includes the steps of doubling, twisting, warping, weaving, post-processing, gluing, tape cutting, and tape winding. During the twisting process, the double-ply cotton yarn is twisted into two directions of "S" twist and "Z" twist, and the same twist is applied during twisting, so that the bandage will not be unraveled due to the strong twisted cotton yarn after weaving. Twist to produce rollover, and can ensure that the bandage surface is smooth and free of weaving defects. Wherein the gluing adopts the method of direct air-per...

Embodiment 2

[0020] The viscoelastic elastic biological bandage of the present invention uses semi-combed cotton yarn as raw material, and is coated with pressure-sensitive adhesive on the bandage base cloth. Make the bandage sticky to a certain extent, while retaining the elasticity and resilience of the cotton elastic bandage, so that an appropriate compression force will be generated during use, so as to achieve the therapeutic purpose of helping recovery. Its manufacturing method includes the steps of doubling, twisting, warping, weaving, post-processing, gluing, tape cutting, and tape winding. During the twisting process, the single-ply cotton yarn is twisted into two directions of "S" twist and "Z" twist, and the same twist is applied during twisting, so that the bandage will not be produced due to the untwisting of the strong twisted cotton yarn after weaving. It can be turned over, and it can ensure that the surface of the bandage is flat and free of weaving defects. Wherein the g...

Abstract

The present invention discloses an adhesive elastic bandage which is made of semi-combed cotton yarn and pasted with zinc oxide or pressure-sensitive adhesive on the cloth of the bandage and the manufacturing method of the adhesive elastic bandage. The bandage of the present invention has certain adhesive, the cloth is flat and the elasticity is even; meanwhile, the elasticity and restoring force of complete cotton elastic bandage are preserved; when in use for enswathement, the bandage does not slide off or loosen; moreover, the present invention has great ventilation property, fully embodying the character of humanization.
