Problems solved by technology

[0004] However, after the polyester fabric is dyed, due to the low affinity of the surface of the polyester fabric to the dye molecules, the dye molecules on the fabric are easy to migrate to the surface of the fiber, resulting in a decrease in color fastness.

Embodiment 1

[0023] A processing method for improving the dye fastness of polyester fabrics, comprising the following steps:

[0024] (1) Pretreatment: Soak the polyester fabric in an ethanol solution with a mass fraction of 30% at 55°C for 30 minutes, then filter, and dry to constant weight;

[0025] (2) Plasma treatment: use a cold plasma processor, first vacuumize, so that the initial pressure of the treatment environment is a vacuum pressure of 0.05MPa, then inject nitrogen, and then conduct discharge treatment, the treatment time is 30min;

[0026] (3) Preparation of active treatment liquid: uniformly disperse nano-silica into the coupling agent solution at a ratio of 60g:280mL, stir at 52°C for 1.5 hours at 1000r / min, then perform suction filtration, and use deionized Water is cleaned, and dried to constant weight, then the nano-silica after processing is evenly dispersed in the maleate solution of 5.3% by mass fraction, and the mass ratio of nano-silica and sodium maleate solution i...

Abstract

The invention discloses a processing method for improving the colour fastness of a dacron fabric and relates to the technical field of processing of clothes. The processing method comprises the following steps: (1) pretreatment; (2) plasma treatment; (3) preparation of active treating fluid; (4) modification treatment; (5) ultrasonic processing; and (6) cleaning. By virtue of performing surface low-temperature plasma treatment on the dacron fabric, the surface substantivity of the dacron fabric can be obviously improved, and the combination property of the dacron fabric with dye molecules is promoted, so that the colour fastness is improved.

Description

technical field [0001] The invention belongs to the technical field of apparel processing, and in particular relates to a treatment method for improving the dyeing fastness of polyester fabrics. Background technique [0002] my country is the world's largest producer, exporter and consumer of textiles and clothing, and its export volume accounts for more than a quarter of the global export trade. Textile fabrics are related to all aspects of people's lives. [0003] Polyester is a kind of synthetic fiber with simple production process and cheap spacing. It has the advantages of strong and durable, good elasticity, not easy to deform, corrosion resistance, insulation, etc., and is widely loved by people. [0004] However, after the polyester fabric is dyed, due to the low affinity of the surface of the polyester fabric to the dye molecules, the dye molecules on the fabric are easy to migrate to the surface of the fiber, resulting in a decrease in color fastness.
