Abstract
The invention discloses a watchband made of silica gel and a producing method of the watchband. A character pattern ink layer printed on at least one surface of the watchband is durable, abrasion resistant and not apt to release. The watchband comprises a base band and a composite layer composed of at least one unit composite layer, wherein each unit composite layer is formed by a thin film and the character pattern ink layer printed on the inner surface of the thin film, the composite layer is bonded or permeated on the surface of the base band in a liquid state vulcanizing or solid state vulcanizing forming method in the mode that the character pattern ink layers are overlapped between the surface of the base band and the inner surface of the thin film. The watchband is soft and good in toughness. The character pattern ink layers are overlapped between the thin film and the silica gel base band, and the character pattern ink layers, the thin film and the base band are tightly combined under effect of high temperature. Character patterns are printed on the thin film in large-scale printing mode so that cost is reduced and time is saved.
