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

Cotton fabric environmental protection dyeing
Technical field
The present invention relates to the lining process field, particularly relate to a kind of cotton fabric environmental protection dyeing.
Background technology
Comprise among the APEO that NPE (NPEO) accounts for 80-85%, OPEO (OPEO) accounts for more than 15%, and dodecyl phenol polyethenoxy ether (DPEO) and binonylphenol APEO (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.Multiple excellent functions such as the APEO series of products are wetting because of having, infiltration, emulsification, dispersion, solubilising, decontamination are so the consumption wide in variety that relates in the textile auxiliary is big.As in wetting agent, bleeding agent, scouring agent, emulsifying agent slurry, soaping agent, the dispersant all more or less contain APEO.
Since APEO to the potential harm of environment by extensive studies and demonstration; Thereby each state has all formulated the content of relevant criterion and regulation limitations APEO; Pollute lining 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 is produced 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; Said pre-treatment step comprise boil float → heat washes → wash water, is specially:
(110), boil and float: put into the first road body lotion, the first road body lotion is heated to 60 ℃, then grey cloth is gone into the first road body lotion, in the first road body lotion, adds the NaOH of 2g/L, and changes material 5 minutes, adds H again 2O 2, be warming up to 95 ℃, and be incubated 40 minutes, be cooled to 60 ℃ then, discharge the first road body lotion, put into the second road body lotion;
(120), heat washes: the said second road body lotion is warming up to 80 ℃ and be incubated 6 minutes, is cooled to 60 ℃ then, discharge the second road 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; Said staining procedure is specially: put into the 5th road body lotion, and the 5th road body lotion is heated to 60 ℃, in the 5th road body lotion, add dyestuff then and changed material 20 minutes, row machine 6 minutes adds Na again 2SO 4And change material 20 minutes, and row machine 6 minutes then adds NaOH and changed material 30 minutes, and row machine 6 minutes is incubated 30 minutes to 90 minutes with the 5th road body lotion at 60 ℃ then, discharges the 5th road body lotion at last;
(300), post processing: the grey cloth after will dyeing carries out post processing.
In preferred embodiment of the present invention; Said post-processing step is specially: put into the 6th road body lotion, wash water is four times at normal temperatures, discharges the 6th road body lotion; Put into the 7th road body lotion; The 7th road body lotion is warming up to 85 ℃ and be incubated 15 minutes, lowers the temperature and discharge the 7th road body lotion, put into the 8th road body lotion and carry out wash water one time.
In preferred embodiment of the present invention, said grey cloth is the cotton fabric grey cloth.
The invention has the beneficial effects as follows: cotton fabric environmental protection dyeing of the present invention, whole process flow only adopts NaOH, H 2O 2And Na 2SO 4Three kinds of auxiliary agents, the blowdown that is produced does not contain APEO or COD, and the lining of being produced is through detecting the standard that meets the REACH rules fully.
