Description

Auxiliary dyeing mechanism for ramie fabric Technical Field The utility model relates to the technical field of printing and dyeing equipment, in particular to an auxiliary dyeing mechanism for ramie fabric. Background The ramie fabric is a natural fiber fabric, mainly derived from fibers of ramie plants, and is widely applied to the fields of clothing, home textiles and the like due to good air permeability, hygroscopicity and antibacterial property. However, the ramie fabric has a relatively low dye-uptake rate in the dyeing process due to the relatively coarse and hard fiber structure and more gaps, namely the dyeing is relatively difficult, so that the use of the ramie fabric is severely limited. The conventional solution is to add an accelerating agent in the dyeing process of the ramie fabric so as to improve the dyeing rate of the dye on the ramie fabric and ensure the dyeing effect of the ramie fabric. However, most of existing dyeing promoters are to directly soak the ramie fabric in the dyeing promoter solution, and the dyeing promoter can act on the ramie fibers only after the ramie fabric is soaked for a long time, so that dyeing processing efficiency of the ramie fabric is affected. Disclosure of utility model The utility model aims to overcome the defects in the prior art and provides an auxiliary dyeing mechanism for ramie fabric.
