Abstract

The invention relates to the technical field of loose wool dyeing, in particular to a low-temperature dyeing method of rabbit wool. The method comprises the following steps: adding raw rabbit wool toa dyeing machine which is a normal-temperature dyeing machine; adding water based on the specified volume; then adding a penetrating agent and glacial acetic acid; stirring for 10min; adding dye, wherein the dye comprises reactive yellow 4RFN, reactive red W-DF and reactive deep blue M-2GE; stirring for 15min, and then increasing the temperature to be 85 DEG C; maintaining the temperature for 30min; washing; then adding a smoothing agent after washing; increasing the temperature to be 45 DEG C; maintaining the temperature for 20min; moving out of vat, thus finishing dyeing. According to the method, the rabbit wool can be dyed under the temperature of 95 DEG C, so that the damage to the rabbit wool fibers can be extremely reduced; moreover, the water, the electricity and the gas are saved,so that the energy consumption is decreased; the processes are simple; the dyeing costs a little time; the dyeing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of loose hair dyeing, in particular to a low-temperature dyeing method for rabbit down. Background technique [0002] In the prior art, the dyeing of rabbit down is carried out at a dyeing temperature above 100°C, which will not only cause damage to the rabbit down fiber, but also cause waste of electricity, water and gas, high dyeing cost, and at the same time there will be Certain pollution. Contents of the invention [0003] The purpose of the present invention is to provide a low-temperature dyeing method for rabbit down at a lower temperature to reduce damage to rabbit down fiber and lower cost in order to solve the above technical deficiencies. [0004] In order to achieve the above purpose, a kind of low-temperature dyeing method of rabbit down designed by the present invention adopts a normal temperature dyeing machine, puts the raw material of rabbit down into the dyeing machine, and adds a speci...
