Disperse dye printing technology for polyester blanket

Abstract

The invention discloses a disperse dye printing technology for a polyester blanket. The technological process comprises steps of printing, pre-baking, aging, washing and tender drying. With adoption of either low-temperature dyeing carrier printing technology or high-temperature and high-pressure aging printing technology, the medium-temperature AF-series disperse dye can guarantee chromatic aberration in a range from grade 4 to grade 5, color reproducibility and brilliance are good, the shape of a color fixation rate curve is more flat or a flat area is wider, mutual splicing is facilitated, dye molecule particle size and particle size distribution are more concentrated, crystal form stability and reproducibility are good, the hue change in certain temperature fluctuation range is small, and front and back roll-to-roll shading is more stable; and besides, the dye has good synchronous fadedness, light fastness and staining fastness and totally meets JIS (Japanese industrial standards) of Japanese textile testing, and the rate of graded products of warp knitting fabric blanket and woolen blanket production is higher than 98%.

AI Technical Summary

Benefits of technology

This patented technology allows for better control on how colors appear when printed onto fabrics during manufacturing processes such as weaving, embroidery, dying, etc., resulting in improved quality products made from these materials.

Problems solved by technology

This patented describes different types of materials that can show good resistance against water or chemical agents such as solvents during cleanup operations on fabrics made from synthetic fibers like nylon-66 (N66). These properties make these fabrics ideal candidates for use in various applications where they come into contact with liquids containing harmful substances. Different methods were developed overall, but it was found difficult to achieve consistently results due to factors including poor fixing rates at lower temperatures, issues with compatibility between colored threads, difficulty controlling the desired degree of brightness, and potential damage caused when exposed to harsh environments involving strong acids or bases.
