Abstract

The invention relates to the field of textile dyeing and finishing treatment, and concretely relates to a terylene fabric dispersive dyeing non-reduction cleaning technology. A high alkali-resistant dispersive dye is used for dyeing the terylene fabric, an alkaline solution is used for dyeing the terylene fabric, and soaping and washing can be carried out. The terylene fabric dispersive dyeing non-reduction cleaning technology does not require a reducing agent for reduction cleaning on dyeing terylene fabric, and can effectively remove floated color and color spot on the surface of the fabric,the dyed fabric can obtain the stable colored light and excellent washable color fastness, the technology is simplified and is more environmentally friendly, and reduces the enterprise cost, and increases the enterprise benefit.

Description

Technical field [0001] The invention relates to the field of textile dyeing and finishing, in particular to a non-reduction cleaning process for polyester fabric dispersion dyeing. Background technique [0002] Polyester fabrics are usually dyed with high temperature and high pressure at pH 5-6 using disperse dyes. After dyeing, in addition to the floating color caused by the dyes attached to the surface of the fabric, the oligomers contained in the polyester will also dissolve during the high temperature and high pressure dyeing process, and will deposit on the surface of the fabric during the cooling process to form stains, which will affect the dyeing of the polyester fabric. quality. The reduction and cleaning of dyed polyester fabrics with reducing agents such as sodium hydroxide is currently the most common and effective method to remove floating and stains on the surface of the fabric. However, the reducing agent removes stains based on the damage of the dye, and the rem...
