Embodiment Construction

[0014] The embodiments of the present invention are described in detail below.

[0015] The fabric used in this embodiment is pure cotton fiber knitted fabric.

[0016] 1. Preparation and selection of natural plant dyes: walnut bark is selected as the raw material of plant dye extracts. First wash the walnut bark and boil it, then extract the boiled juice into the dye solution. When extracting the dye solution, add potassium carbonate lg / L (pH 9).

[0017] 2. Dyeing: dyeing equipment, rope dyeing machine: dye: walnut bark vegetable dye extract 25% (o.w.f.)

[0018] 3. The initial dyeing temperature is 45℃, keep for 30min. Raise the temperature to 95℃, keep for 20 min.

[0019] The specific process: Desizing in the tank→draining, watering→washing with running hot water for 1 pass→draining, watering→washing with running warm water for 1 pass→draining, watering→adding leveling agent and dye, stirring even→dyeing (initial Dyeing temperature is 45℃, keep for 30min. Raise the temperature to...

Abstract

The invention discloses a method for harmless dyeing of school uniform fabric. The method is characterized in that textile fiber fabric is dyed by adopting a natural vegetable dye dyeing method; the textile fiber fabric is completely prepared from textile fibers as raw materials by conventional processing equipment.

Description

Technical field [0001] The invention discloses a harmless dyeing method for fabrics of school uniforms. In particular, the present invention relates to a method for dyeing school uniform fabrics made from textile fibers dyed with natural plant dyes. Background technique [0002] At present, textile fiber fabrics are widely used in the production of school uniforms in my country's universities, middle and elementary schools and various schools. Moreover, at present, almost all textile fiber fabrics are dyed by chemical synthetic dyes. We all know that most of the chemically synthesized dyes are extracted and synthesized from petroleum. This part of the product can decompose more than 20 kinds of carcinogenic or allergenic banned azo dyes and can also dissociate lead and lead under certain conditions. Heavy metal ions such as chromium and mercury are harmful to the human body and the environment. As a chemical synthesis product, synthetic dyes are more or less harmful to the hum...
