This invention discloses an intelligent dyeing and finishing equipment and process for Tencel-linen blended woven fabrics, relating to the field of dyeing and finishing equipment technology. It includes a dye liquor shell with an installation mechanism for dyeing and finishing the Tencel-linen blended woven fabric. The installation mechanism utilizes the meshing transmission of a first bevel gear and a second bevel gear to drive a stirring bracket and a spiral fan blade to form a vortex, causing the dye liquor to flow upwards in a spiral shape. This ensures thorough mixing of the dye liquor while preventing direct impact on the Tencel-linen blended woven fabric, thus preventing fabric damage or uneven dyeing. A disturbance plate swings up and down within a slide rail bracket, working in conjunction with the spiral dye liquor flow, essentially providing micro-vibration "assisted turning" from below the fabric. This ensures that the front and back sides and the middle layer of the Tencel-linen blended fabric are evenly contacted with the dye liquor, while simultaneously dislodging air bubbles from the gaps in the linen fibers, preventing air bubbles from hindering dye liquor penetration and solving the problem of difficult linen fiber penetration.

The invention relates to a phenoxazine dye intermediate, a dye precursor, a dye and a preparation method thereof, and belongs to the technical field of dyes. According to the phenoxazine type dye, the phenoxazine intermediate is used as a dye matrix, cyanuric chloride and genipin double active groups are grafted, and the phenoxazine type dye intermediate has excellent color light stability, high color development intensity and bright color light and can dye fibers in supercritical fluid. An iridoid structure of genipin reacts with amino groups on protein fibers, and a fiber-dye-color trinity is generated in the dyeing process. The phenoxazine dye does not need to be applied to water and other dyeing assistants in the dyeing process, the dyeing mode is novel and special, the dyeing process is green and environment-friendly, the dye is friendly to equipment, and the phenoxazine dye has a good application prospect in the aspect of supercritical CO2 dyeing.
