The invention discloses a
dyeing treatment process for pure cotton fabrics based on pure natural biological preparations, which is designed for solving the technical problems that the environment is seriously harmed in an existing pure cotton fabric
dyeing treatment process, and the
human health is harmed in an application process. The adopted technical scheme is as follows: the
dyeing treatment process comprises the steps of singeing,
desizing, boiling-out, bleaching, dyeing,
softening treatment and preshrinking treatment, and the key point is that biological preparations, which are respectively a
desizing enzyme solution, a boiling-out
enzyme solution,
glucose oxidase solution and a
plant dye, are respectively adopted in the steps of
desizing, boiling-out, bleaching and dyeing. The dyeing treatment process has the technical effects that the operation is simple; the pure natural biological preparations almost do not contain any toxic substance, and
wastewater produced in the treatment process is less and biodegradable, so that under the premise of keeping the characteristics such as softness, sweat absorption, comfortableness and naturalness and the like of pure cotton fabrics, the harm to the environment is alleviated, and the harm to
human body is avoided, and therefore, the process has a zero-
pollution environmental friendliness characteristic.
