Abstract

The invention relates to the field of textile printing and dyeing technologies, in particular to a fabric printing and dyeing pretreatment refining agent and a preparing method thereof. The fabric printing and dyeing pretreatment refining agent is prepared from, by mass, 5-10% of modified clay and 1-5% of a polymer rare earth complex. The preparing method of the refining agent has the advantage ofbeing simple; the refining agent is used for refining textiles, the cleanliness, whiteness, capillary effect, strength and internal texture of the textiles can be significantly improved, and the refining agent also has an obvious effect of deepening and brightening during dyeing.

Description

technical field [0001] The invention relates to the field of textile printing and dyeing technology, in particular to a fabric printing and dyeing pretreatment refining agent and a preparation method thereof. Background technique [0002] Refining is a very important process in the pre-treatment process of fabric printing and dyeing. The purpose is to remove natural impurities such as pectin, wax, cottonseed hulls and chemical impurities such as oils and sizing on the fabric, reduce the impurity content on the fabric, and improve the quality of the fabric. Water absorption and whiteness. Generally speaking, these impurities can be converted into soluble substances and removed under alkaline conditions, but some substances such as waxy substances must be removed by emulsification. , in addition to the alkali agent, it is also necessary to add a certain amount of refining agent, so that the scouring liquid can penetrate into the fabric evenly and quickly, give full play to it...
