Analysis on the Application of Chemical Dyes by Environmental Dyestuff Manufacturers

Analysis on the application of chemical dyes by environmental protection dye manufacturers 1. Select chemical dyes according to fiber properties. Because of their different properties, various fibers need to choose suitable chemical dyes when they are dyed. For example, when cotton fiber is dyed, because its molecular structure contains many hydrophilic hydroxyl groups, it is easy to absorb moisture and expand, can react chemically with reactive groups, and is more alkali-resistant, so you can choose direct, reduction, vulcanization, ice chemistry Dyes and reactive chemical dyes. Polyester is highly hydrophobic and is not resistant to alkali at high temperatures. Under normal circumstances, the above chemical dyes should not be used, but disperse chemical dyes should be selected for dyeing.

Introduction of active color fixing agent manufacturers on issues related to textile color fastness

Introduction of active color fixing agent manufacturers on issues related to textile color fastness

Manufacturer of active color fixing agent: Fabric dyeing fastness (referred to as dyeing fastness) refers to the degree to which dyed or printed fabrics fade under external factors such as compression, friction, washing, rain, sun exposure, finishing, seawater immersion, saliva immersion, water stains, sweat stains, etc This is an important indicator of the fabric during use or finishing. Good dyeing fastness, fabric products are not easily faded during finishing or use; If the dyeing fastness is poor, there may be fading, slight fading or staining, which can cause a lot of trouble.

Manufacturers of active color fixing agents: related content and methods of dyeing

Active color fixing agent manufacturer: The printing and dyeing factory selects dyes based on the fastness performance provided by the dye color card and sample testing to determine the wet treatment fastness level of the dyes. Because the color fastness provided on the color card is for deep dyeing at a dye concentration of 1/1, it can only be used as a reference, with the latter being the main focus.

Production process of printing and dyeing factory applying environmental protection immediate chemical dyes程

Production process of printing and dyeing factory applying environmental protection immediate chemical dyes程

The production process of environmental protection immediate dyestuffs in printing and dyeing factories is generally: two soaking and two padding-steaming (102~105℃, 45~60s)-water cleaning-(color preservation solution)-air drying. Roll-coil dyeing is the process of dipping textile fabrics in a pad-dyeing solution, rolling them, leaving them idle for a period of time under the condition of slow rotation, and then post-processing. Energy-saving instant dyes for polyester/cotton (polyester/viscose) textiles: polyester/cotton, polyester/viscose blended cotton fabrics and other chemical fibers with different characteristics are dyed in the same bath. This requires that the instant dyes have high-quality high-temperature reliability and Excellent improving power and repeatability, good color fastness and environmental protection characteristics.

Difficulties in the application of immediate dyes for environmental protection

Difficulties in the application of immediate dyes for environmental protection

Environmental protection immediate dyes refer to dyes that meet the requirements of environmental protection and can be used in the production process. Environmental protection dyes should meet the following standards and have no or no impact on aromatic amines; the dye itself has no carcinogens, allergens, acute toxic side effects; indoor formaldehyde and purifiable heavy metals after application exceed the limit below the limit; no natural environment growth hormone; no continuous Organic chemical air pollutants; harmful organic chemicals that are not easy to cause environmental pollution; compounds that are not easy to cause environmental pollution; color fastness to washing and performance indicators are better than prohibiting the use of dyes.
