Abstract
The invention discloses a green environment-friendly dyeing process for all-cotton fabrics, which particularly comprises the following steps of boiling and bleaching, hot washing, water washing, dyeing, posttreatment. The green environment-friendly dyeing process for all-cotton fabrics of the invention adopts only three additives of NaOH, H2O2 and Na2SO4 during the whole process flow; the produced pollutant discharge does not contain APEO or COD; the produced fabrics completely meet REACH regulations after detection.
Description
Technical field
The present invention relates to the fabric process field, particularly relate to a kind of cotton fabric environmental protection dyeing.
Background technology
Comprise among the APEO that polyoxyethylene nonylphenol ether (NPEO) accounts for 80-85%, OPEO (OPEO) accounts for more than 15%, and dodecyl phenol polyethenoxy ether (DPEO) and Dinonylphenol Polyoxyethylene Ether (DNPEO) respectively account for 1%.APEO can be summarized in following four aspects to ecology influence: toxicity, biological degradability, environmental hormone, produce harmful side product in process of production.The multiple excellent functions such as the APEO series of products are wetting because having, infiltration, emulsification, dispersion, solubilising, decontamination are so the consumption wide in variety that relates in the textile auxiliary is large.As in wetting agent, bleeding agent, scouring agent, emulsifying agent slurry, soaping agent, the dispersant all more or less contain APEO.
Since APEO to environment potential harm studied widely and proved, thereby each state has all formulated the content of relevant criterion and regulation limitations APEO, pollute fabric and in dyeing, will stop APEO, must from whole technical process, stop to contain the use of APEO auxiliary agent.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of cotton fabric environmental protection dyeing, and the blowdown that produces does not contain APEO or COD.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of cotton fabric environmental protection dyeing is provided, and concrete steps comprise:
(100), pre-treatment: at first grey cloth is carried out pre-treatment; Described pre-treatment step comprise boil float → heat washes → wash water, is specially:
(110), boil and float: put into the first body lotion, the first body lotion is heated to 60 ℃, then grey cloth enters the first body lotion, adds the NaOH of 2g/L in the first body lotion, and material 5 minutes, adds H again
2O
2, be warming up to 95 ℃, and be incubated 40 minutes, then be cooled to 60 ℃, discharge the first body lotion, put into the second body lotion;
(120), heat washes: described second body lotion is warming up to 80 ℃ and be incubated 6 minutes, then is cooled to 60 ℃, discharge the second body lotion;
(130), wash water: put into the 3rd road body lotion; Embryo cloth is carried out the wash water first time, and discharge the 3rd road solution; Put into the 4th road body lotion, grey cloth is carried out the wash water second time, and discharge the 4th road body lotion;
(200), dyeing: the grey cloth after the pre-treatment is dyeed; Described staining procedure is specially: put into the 5th road body lotion, and the 5th road body lotion is heated to 60 ℃, then added dyestuff and material 20 minutes in the 5th road body lotion, row machine 6 minutes adds Na again
