Adhesive elastic biological bandage and manufacturing method thereof

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.

Description

technical field [0001] The invention relates to a viscoelastic biological bandage and a manufacturing method thereof. Background technique [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.

[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 process, which requires the use of a large amount of release paper as the carrier of the colloid transfer, and in the gluing process. The method of full coating means that the glue is applied as a complete adhesive film covering the surface of the bandage base fabric, that is, the coating head (squeegee gun) and the coating roller (bottom roller) are applied closely, as shown in Figure 1 , 1', bottom roller, 2', coating head, 3', guide roller, 4', tension control roller, 5', release paper

Apply glue or zinc oxide to the release paper through the coating head (scraping gun), then compound the bandage with the glue-coated release paper, and transfer the adhesive film to the bandage, so that the adhesive film will The meshes are all blocked, and the products produced have poor air permeability; and the release paper cannot be effectively recycled after use, resulting in a lot of waste and inconvenience to users
