Embodiment Construction

[0016] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0017] 1. Dyes and dyeing and finishing methods

[0018] A kind of dyestuff of the present invention, comprises following raw material: Disperse dye FW-N violet 0.8%owf, HAC 0.5g / L, disperse leveling agent 0.5g / L, moisture-absorbing perspiration easy decontamination agent FC226 1.5g / L, degreasing Agent 1.0g / L, acid reducing cleaning agent 3.0g / L and anti-ultraviolet shielding agent 10g / L. Among the present invention, the disperse dye FW-N purple is purchased from Quanzhou Modern Dyestuff Chemical Co., Ltd., and the moisture-absorbing perspiration and easy decontamination agent FC226 is purchased from the U.S. 3M company. In addition, disperse leveling agent, degreaser, acid reduction cleaning agent and All the anti-ultraviolet shielding agents are commercially available.

Abstract

The invention discloses a dye comprising the following raw materials: 0.8%owf of disperse dye FW-N violet, 0.5 g / L of HAC, 0.5 g / L of dispersing and leveling agent, 1.5 g / L of moisture absorbing, sweet releasing and dirt repelling agent FC226, 1.0 g / L of degreasing agent, 3.0 g / L of acidic reduction cleaning agent and 10 g / L of uvioresistant shielding agent. The invention further discloses a method for dyeing and finishing a polyester fabric by using the dye, and the method comprises the steps such as embryo setting, dyeing and finished product setting. The method has the following beneficialeffects that (1) the relevant fastness of the fabric treated by using the disperse dye FW-N violet is improved, so that the problems of relevant fastness and brightness caused by dye character in workshop production are solved; and (2) the fabric achieves moisture absorbing, sweet releasing and dirt repelling functions after being treated by using the moisture absorbing, sweet releasing and dirt repelling agent FC-226.

Description

technical field [0001] The invention belongs to the technical field of knitted fabric processing, in particular to a dye and a method for dyeing polyester fabric using the dye. Background technique [0002] Traditional knitted fabrics have poor relative fastness (washing fastness, light fastness, PVC color migration), and their moisture absorption and decontamination capabilities are not satisfactory. [0003] Through the screening of the dyes on the market, it is found that FW-N Brilliant Red (also known as Disperse Violet FW-N) has a better dyeing effect on polyester fabrics, and it can achieve a very bright effect without using fluorescent dyes. All fastness tests are good. [0004] Moisture-wicking and easy-to-decontamination agent FC-226 is a product developed for polyester fabrics to make it have a long-lasting moisture-wicking and easy-to-decontaminate effect. FC-226 can also slightly improve the softness of the fabric and increase the lubricity of the dye tank. C...
