Embodiment Construction

[0016] The present invention relates to polyester / sorona blended fabric disperse dye one-bath method dyeing method, described method comprises the following processing steps:

[0017] Put the polyester / sorona interwoven fabric in water with a bath ratio of 1:10 at room temperature, add dispersant NNO 0.5 g / l and self-made carrier solution, circulate for 10 minutes, then add disperse dyes, and adjust the dye ratio according to different color requirements , when the pH value is adjusted to 5.5 with HAC, the cycle runs for 5 minutes, and then the temperature is raised to 110°C at 2°C / min, and the holding time is 50min. After dyeing, wash with water, wash with reducing cleaning solution (composed of 1.5g / L soda ash and 1.5g / L sodium hydrosulfite), and treat at 70°C for 20min.

[0018] The present invention adopts the method of adding self-made carriers in the dye liquor, and the above-mentioned dyeing process that takes, only the consumption of self-made carriers in the dye liquo...

Abstract

The invention relates to a polyester / sorona mixed fabric disperse dye one-bath process dyeing method. According to the determined optimal dyeing process of polyester / sorona mixed fabric, the dye dosage is greater than or equal to 2% (owf), the pH value is 5.5, the dyeing time is 50 minutes, the dyeing temperature is 110 DEG C, and the carrier dosage is 1.5g / L. The result indicates that the dyeing method can obtain a product with stable color light, good homochromatism and high color fastness; and the process is simple, the time is short, and the production cost is low.

Description

technical field [0001] The invention relates to a one-bath method for dyeing polyester / sorona interwoven fabrics with disperse dyes, belonging to the technical field of textile printing and dyeing. Background technique [0002] Sorona is a fiber newly launched by DuPont of the United States that perfectly combines functions and environmental protection. It is synthesized by biochemical methods, and 37% of the raw materials come from natural renewable resources; the fabric formed by interweaving Sorona and polyester has an extremely soft feel and long-lasting Excellent shape retention, bright colors, excellent color fastness, good moisture absorption and perspiration performance, comfortable stretch recovery, stain resistance and wrinkle resistance, so it is favored by consumers and has a good market prospect. Polyester / sorona blended fabrics have different dyeing properties due to the differences in physical properties and chemical structures between polyester fibers and Sor...
