Abstract
A manufacturing method of a viscoelastic bandage, having a nonwoven fabric, an elastane yarn, base cloth, and natural latex or synthetic latex as main raw materials. A viscoelastic bandage suitable for such trades as medical bandaging, industrial operation protection, field operation and sports protection can be manufactured after going through the following steps, manufacturing of the elastic base cloth→surface treatment→anti-seizing treatment→adhesive coating process. Provides high production efficiency and low cost, suitable for an industrialized mass production, with outstanding comprehensive processing economy and very powerful market competitiveness. Besides, the product has the following properties and characteristics: (1) Breaking tenacity up to 180-220 KN/m; (2) tensile ratio up to 80-120%; (3) good air permeability; (4) perfect stripping uniformity; (5) stable product property and longer storage life; and (6) attractive appearance; there is no rough fiber on the exterior surface of the nonwoven fabric any more.
