Details

Dyeing and finishing processes of production and application of water analysis to improve production quality and finishing, and finishing the water quality of water is closely related to saving energy and reducing consumption of all printing and dyeing enterprise managers need to think about. In response to this problem, our company over the past five years and dozens of printing and dyeing enterprises, large quantities of water for dyeing and printing characteristics, combined with the user's actual situation, the development of new water sources, using the approach of the depth of the water resources through processing, to replace the municipal tap water, can significantly reduce production costs. However, with economic development, water quality around the river has been polluted to varying degrees, the company's water treatment works for many years of practical experience, combined with water features of printing and dyeing, summing up a set of specialized response to deal with all types of water quality for printing and dyeing water supply and technology process.

2, printing and dyeing of indicators and analysis of water

Note: The data refer to "Printing and Dyeing Manual"
2.2 Water Quality Objectives and impact analysis of staining
2.2.1 Turbidity
Turbidity was the result of water containing suspended and colloidal particles state.
Suspended and colloidal particles on the surface of dyed goods have a greater impact of stains, stain, it is necessary to strictly control the turbidity. "Handbook of printing and dyeing" 5FTU index value requested in the application process will be stained a marginal impact, and I practice in project control turbidity 1FTU the following indicators.
2.2.2 Chromaticity
Color is water-soluble humus, organic or inorganic substances caused, but also caused by industrial wastewater. Staining is used to dye the fabric according to a certain method of dyeing process is a kind of absorption, diffusion process, if the dyes dissolved in aqueous solution exists in color, the color of dye is bound to interfere, resulting in color dyeing phenomenon appears. This phenomenon of light-colored dyeing the impact of which is obvious for the more stringent of the requirements of color, generally require no more than 10 times.

2.2.3 pH

2.2.4 Hardness
Water hardness is mainly calcium and magnesium ions formed as a result of the heating process breaks down into the sediments. Dyeing process of dyes and auxiliaries easily produce precipitation, resulting in uneven staining and the brightly-colored and color fastness to decline, but also to make soap soap to generate insoluble calcium and magnesium precipitation pattern in the formation of stains on the fabric stains, fabrics feel the impact and luster, and there will be serious "white powder. "
2.2.5 Fe-Mn-ion
Mainly in the water solubility of divalent iron, manganese ions exist, the state is very unstable and the oxidation of divalent iron ions after the oxidation of insoluble trivalent iron, divalent manganese ions will be oxidized into insoluble tetravalent manganese. Mn ions in ultra-high dye, the dyeing process of the full oxidation of sediments will cause increased dye color to dye colored surface,
2.2.6 Oxygen Consumption
It is said that the water reducing the number of an indicator material. Include a variety of organic matter, nitrite, sulfide, ferrous salt, but is mainly organic matter, reflecting the degree of organic pollution. Mainly refers to water of organic humic acid and fulvic acid polycarboxylic acid compounds, sewage and industrial wastewater pollutants.
The existence of organic dye in the organic matter willin dyeing, the dyeing phenomenon appears dark shade wilt.
2.2.7 Total Solids
