| titleOfInvention | Polyformaldehyde fiber dyeing method |
| abstract | The invention relates to a polyformaldehyde fiber dyeing method, which comprises the following steps: firstly, cleaning polyformaldehyde fibers with a degreasing agent, and then carrying out pretreatment; preparing a dye solution by using a disperse dye and a dye carrying agent solution; then putting the pretreated fiber into a dye solution for low-temperature dyeing; and after dyeing, reducing, washing and drying. The dye-carrying agents used in the low-temperature dyeing method are all environment-friendly ester micromolecular compounds, no residue is left in dyeing, no pollution is caused to the environment, no dispersing agent or leveling agent is required to be added in the dyeing process, and dyeing wastewater is easy to treat; the dyeing method has the advantages of low dyeing temperature, energy consumption saving, good dye uptake and apparent depth of the dyed polyformaldehyde fiber, no damage to the strength of the fiber, and good soaping fastness. |
