Silk uniformly dyeing method

Abstract

The invention discloses a silk uniformly dyeing method. The silk uniformly dyeing method comprises A, dye liquor preparation including dissolving and uniformly mixing dye liquor of dye solution and auxiliary solution in soft water according to dyeing process requirements and storing the mixtures in liquor storage barrels for standby application;, B, dye liquor conveying including mixing and inputting the dye solution and the auxiliary solution at a ratio of 5:1 into a padding liquor tank at 18-35 DEG C, C, dye liquor padding including continuously and smoothly immersing silk fabrics into the dye liquor inside the padding liquor tank to absorb the dye liquor, and rolling up the dyed silk fabrics, and D, stacking including instantly wrapping the rolled silk fabrics and shaft ends tightly with films, stacking the wrapped silk fabrics in a rotating state with a rotating speed of 4-8 r / min and an environment temperature of 15-35 DEG C for 5-24 hours. The silk uniformly dyeing method saves vapor and auxiliaries and has the advantages of being high in dye utilization rate, low in dyeing wastewater and environmentally friendly; the dyed fabrics are higher in permeability, uniformity and flatness than fabrics dyed through conventional methods.

Description

technical field [0001] The invention relates to a silk dyeing method, in particular to a dyeing method of padding dye solution at room temperature, winding, covering and stacking to achieve uniform dyeing of dyes. Background technique [0002] The existing silk dyeing method is to adopt the exhaust dyeing method, and the liquor ratio is generally between 1:10 and 1:50 (that is, 1kg of fabric needs 10 to 50kg of water). The dyeing agent and leveling agent are used for high-temperature dyeing (generally at 75°C to 95°C); the disadvantage is that it consumes a lot of steam, water and auxiliaries; and the utilization rate of dyestuffs is low, the discharge of dyeing wastewater is large, and the environmental pollution is serious. Contents of the invention [0003] In order to overcome the technical defects in the above-mentioned prior art, the object of the present invention is to provide a dyeing method for evenly dyeing silk. High efficiency, high dyeing quality, and enviro...
