Embodiment 4

[0105] The energy consumption contrast of embodiment 4 and comparative example 1 :

[0106]The chromatic monomers contained in the disperse dye composition in Example 4 are: Disperse Orange 30#, Disperse Red 60# and Disperse Blue 56#; the contained auxiliary agents are sodium lignosulfonate and leveling agent; traditional dyeing methods are used , using water-based dispersion at 130-135°C, in a high-temperature and high-pressure dyeing machine, use 6X105Pa high-temperature steam to heat the dyeing process, that is, use 160°C high-temperature steam to heat the liquid with dye, and directly pass the high-temperature steam into the dye liquid.

[0107] The energy consumption in Example 4 is: the difference in heating value per unit volume of water heated from 30°C to 130°C: 503.67-125.69=377.98J / kg, the heating value released by cooling the unit volume of water from 160°C to 120°C: 675.33-503.67= 171.66J / kg, 120°C dyeing steam consumption per unit volume of water (theoretical ...

Abstract

The invention relates to a disperse dye composition and an application method of the disperse dye composition. During dyeing polyester-cotton blended fabrics, the disperse dye composition can be adopted to remove traditional necessary technical step of reducing and cleaning after dyeing through the disperse dye, therefore, the energy is saved, the production efficiency is improved, and high color fastness can be ensured. The benzoic acid is added to the disperse dye composition to be served as a carrier, therefore, the disperse dye composition provided by the invention can be used for dyeing the polyester fiber at 110 to 120 DEG C without influencing the color fastness and degree of dyeing; meanwhile, the benzoic acid is served as a solid food additive; compared with a traditional carrier, the disperse dye composition can not harm a human body, and has high environmental-protection characteristics; and when the disperse dye composition is applied to pure terylene fabric, the residual dyeing temperature can be utilized for reducing and cleaning by adding sodium formaldehyde sulfoxylate composition without draining liquid, therefore, the resource consumption is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a dye composition, in particular to a disperse dye composition for polyester fiber dyeing. Background technique [0002] In recent years, with the continuous improvement of living standards, people have higher and higher requirements for clothing. High color fastness requirements are generally required. Traditional disperse dye products can no longer meet people's requirements. This requires dye manufacturers to develop dyes with high color fastness requirements to meet customer needs. [0003] In recent years, as the price of cotton yarn continues to rise, the cost of pure cotton clothing has risen sharply. In order to reduce costs, it also improves the wearability of clothing. Polyester-cotton blended fabrics are becoming more and more popular. [0004] Traditional polyester-cotton blended fabrics are dyed with disperse dyes at high temperature, and then cotton fibers are dyed with reactive dyes. Generally, after dyeing...
