But in the past, there were few red disperse dyes with particularly good light fastness to dye these fabrics such as car interiors. Therefore, as an understanding of the above situation, there is an urgent need for disperse dyes with high light fastness for polyester fibers to meet the needs of the market. Require

[0021] According to the data shown in Table 1, after pre-dispersing and crushing the original dye monomer A, dye monomer B and dye monomer C in the metering ratio, add a dispersant and warm water to stir, disperse and dissolve, repeat through continuous grinding and filtration, sand After grinding to the end, it is sent to a spray drying tower through a pipeline for drying, and at the same time, dust-proof oil and dispersant are sprayed evenly, and finally the finished product is packaged.

The invention relates to a disperse red dye with high light fastness for polyester fiber, and the dye comprises the following components by weight percent: 10-60% of dye monomer A, 20-70% of dye monomer B, 5-40% of dye monomer C and the balance of auxiliaries. The disperse dye can be used for dyeing of polyester fiber automobile interior fabric and other products, and the use of the dye can reduce the phenomena of color change and color fading of the fabric due to solar radiation to the maximum extent, thereby greatly improving the light fastness of the dyed fabric, realizing good dyeing equalization and leading other various items of color fastness to be optimal.
Description
technical field [0001] The invention relates to a red disperse dye, in particular to a disperse red dye (disperse red HLF-E) with high light fastness for polyester fibers. Background technique [0002] Disperse dyes with high light fastness are mainly used in the dyeing of polyester fiber or polyester blended fabrics that require high light fastness, such as curtains, parasols, outdoor products, and automotive interiors. However, these items are usually exposed to sunlight at high temperatures, are prone to color fading, and are difficult to maintain a good color for a long period of time. Therefore, it is necessary to dye polyester fibers for outdoor use with dyestuffs having particularly good light fastnesses. But in the past, there were few red disperse dyes with particularly good light fastness to dye these fabrics such as automotive interiors. Therefore, as an understanding of the above situation, there is an urgent need for disperse dyes with high light fastness for p...
